Print Page - 1971 Oldsmobile Cutlass "S71"

Here you can see the smaller internal webbing supporting the main caps and the otherwise less meaty block of the original 350 engine from the S71 Olds.

Being that this is going to be a turbocharged car, we took a moment to mock up the engine with an idea we had on using the existing exhaust manifolds for the turbocharger. The idea was to flip the manifolds facing forward and have them exit into a pipe under the engine and up into the turbo on the passenger side front of the engine. After several tests, we found that this plan won't work... the manifolds hit the steering box and won't let the block mount where we need it to sit. Incidentally, the 350 block is dimensionally the same as the 350 DX Diesel block for comparison.

You can also see the filler work had begun on the body by this point.

so kevin, on the S71 , did you fab a new frame or did you purchase it, like it is in the picture on page one?.....that frame looks a lot better than the 40 year old stock frame....also in the artist rendering, it looks like oldsmobile rally wheels, but the look like 16 - 17 inch rally's, are you gonna have them special made or can you buy them like that?....I am interested in replacing my old frames, 1965 F85, 1972 442 so I was looking at some options at sema and on your projects......thanks keep the S71 updates coming, oh where are you located approx.?..joe in kansas

Joe,

We reinforced the stock frame on the S71, but we took some cues from the RS Performance frame in the picture on page 1. The S71 frame came out pretty nice after being reinforced and de-burred.

There are several great new frame options out there. The RS Performance frame is very nice, and so are the Art Morrison MAX G chassis. A '66 Chevelle recently won a Car Craft shootout on a Schwartz chassis. Add to that the wide variety of killer bolt-on parts from AirRide, Detroit Speed, Global West, and many others, and you have alot of choices.

The wheels in the picture are indeed oversize Olds Super Stock IIs. There is a company working to make these available in 17 and 18 inch diameters, but their progress has taken a while and the price is pretty high, as they are basically 1-offs. They do look cool, though. We'll post more info on them if they become available, but right now we're leaning in a different direction with the wheels on the car.

Our shop is in the midwest.

We've got much more to post on this car, so keep tabs on this thread for more info.

Nice nice nice. Love that color. You guys have been killing me on this build. Can't wait to start on my "S72" next fall. More more more PLEASE!!!!! Give us all the videos you can. If you guys were in Maryland you'd have to get the cops to evict me from your shop. Love all of the other stuff too, not just the S71. Great stuff.

Thanks Mike! Sounds like you have some cool cars yourself. I dig '87 Monte SSs also.

Here's a little more to tide you over... we built the dash face for the Auto Meter Ultralights we got from the YearOne Speed Shop catalog. This is a little slideshow of the process, it will have more detail in the video. Yes, the car had a Ford Rotunda tach installed since '71...

We used Blair Holcutters to cut the small gauge holes, and the good old HTP plasma torch to cut the panel and the two large gauge holes. We're going to put the Boost and Volt gauges in the dash where the ashtray used to be.

Wow. I think the paint choice is fantastic! I have to say, the S71 is turning out to be my favorite of all the V8TV builds. I'm super excited about the current plans for the motor. It's going to be a beast, for sure, but I'm a bit curious to see how responsive the turbo'd V8 will be on the autocross/road course. Having a turbo'd 428 kick you in the pants at mid-corner might be a bit tricky. :o

Still, I love the idea of turbocharged muscle cars. The F-Bomb Camaro over at CarJunkieTV/Frieburger's Junkyard is a very cool (and expensive) example, although it was designed for an entirely different application.

Title: Re: 1971 Oldsmobile Cutlass "S71"
Post by: Kevin O on December 03, 2008, 08:20:11 AM

The turbo motor is going to be interesting in the autocross, but that's also why it's going to make torque naturally. May have to dial the boost back for those kinds of events.

Here's round 2 of the dash build... we were really impressed how the Eastwood wrinkle black powder matched the factory plastic dash pattern! As always, more to come!

Title: Re: 1971 Oldsmobile Cutlass "S71"
Post by: ZeGerman on December 03, 2008, 11:35:31 AM

Judging by the detail afforded in the photos, the Eastwood wrinkle finish is nearly a dead ringer for the original plastic dash surface. It's hard to believe that a spray-on finish can match so accurately. It looks like the gauge cluster is going to be awesome when finished. Nice work!

Title: Re: 1971 Oldsmobile Cutlass "S71"
Post by: Kevin O on December 03, 2008, 12:39:55 PM

The wrinkle is a powder coat, so it's not exactly "spray on", but it kinda is. The great thing is how hard it is when finished... the coating is like iron. And the texture even feels just like the original plastic.

Thanks again for the positive feedback!

Kevin...

The dash looks great! I'm curious how easy that dash comes out. Was it tough to remove without screwing up the dash pad? Or didn't you guys care cause you planned on replacing it anyway. My 36 year old dash pad is perfect, in fact the interior on my car is the best thing it has going for it.

Title: Re: 1971 Oldsmobile Cutlass "S71"
Post by: Kevin O on December 03, 2008, 02:39:08 PM

The dash wasn't really that hard to take apart, although the guys in our shop did the work. So for me, it was simple! Maybe I can get our man Nick to chime in on the dis assembly process. Actually, it's just a matter of squeezing in the car and disconnecting all the hang-ups, like the heater controls, the ductwork, etc. Our dash pad isn't cracked, but it looks pretty beat, so I think we're having Just Dashes restore it once we get everything mocked up.

Title: Re: 1971 Oldsmobile Cutlass "S71"
Post by: Kevin O on December 07, 2008, 06:53:50 PM

One of the major elements of this build is the turbo system, and we've been contemplating the best way to do the turbo install for many months. I think I finally have an idea of what we're going to do.

There are many factors that needed to be addressed in designing the system, including:

- It's an Oldsmobile, which means you can't just go buy pre-made turbo headers
- It's going to be street-driven, so the headers need to be up to the task from a strength standpoint
- It's a mechanical 4-speed, so the driver side has a linkage clearance obstacle
- We didn't want to cut the car apart to accommodate the system
- Olds manifolds don't fit if you point them forward to plumb the piping in front of the engine
- Olds manifolds are not able to be flipped vertically to point the outlets up

So after much consideration, I think the latest idea is going to require the least amount of fabrication time and the most simplicity. Here's how it goes...

We're going to use the factory Olds exhaust manifolds, pointing in the factory direction. The passenger side manifold actually has a second port where the factory 2-1 exhaust system cross-over pipe would connect.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_08.07.08s_020.jpg)

So we're going to run the exhaust out the driver side, under the motor like a factory 2-1 setup, then out the passenger manifold like a single exhaust car. Then, the plan is to have the exhaust make a 180 degree turn around under the car and come forward up the passenger side. We got this idea from the Turbonetics 2005 Mustang turbo kit...

(http://www.turboneticsinc.com/Library/images/products/large/Mustang_turbosystem_02_sm.jpg)

(http://www.turboneticsinc.com/Library/images/products/large/Mustang_turbosystem_01_sm.jpg)

Then, the turbo will live up on the passenger side of the engine bay, and dump it's exhaust back down the passenger side. This way we're clear of the clutch linkage on the driver side. The turbo will then pressurize an intercooler in the grille area, and force the charge up into the FAST EFI throttle body.

Word on the street is that the cast iron manifolds will handle the heat better than mild or stainless headers, and that the power levels are similar. We'll probably have them coated with some exotic high-temp coating and then milled flat for good sealing.

Another factor is that we already have these in-house, and the fabrication will be minimal. It's such a simple idea, we feel it would be almost irresponsible not to try them. If not, custom stainless headers are only a couple thousand dollars away....

Of course, this strategy might change if we have a bunch of problems, but that's the current plan.

The rear mount deal is a possible solution, but I don't want the system to get that complex. I think this is going to be a nice simple way to put the turbo up behind the core support without 9 miles of tubing. I always wondered about the safety of having the turbo exposed below the car and the oil system being that far away. On a race car it would be fine, but we want this one to be as reliable as possible.

This is the site I've been looking for! Great info. We have an original 1970 Monte Carlo - never wrecked or repainted. We have a similar isue with our rear quarters in that the original is in near perfect shape EXCEPT for the wheel lip. You guys repaired the Olds lip with a TIG, would this repair be do-able on a '70 Monte with a MIG welder? Would having a 1/4" overlap behind the patched lip be prone to rust? What filler would you recommend. Also, how in the hell do you get the female to contribute? My wife says she is interested in me & my son's cars, but as of yet she has not contributed. Even my then 6 year old daughter helped tear down the engine. How long has this site been here?

Hey Tj -

Thanks for stopping by. V8TV has been around since 2004.

As for your quarter panel questions, yes, you can repair them with a MIG. Just take your time, go SLOWLY. I recommend getting some extra steel of the same gauge to practice / set up your welder with. Use a high heat setting, and burn individual tacks quickly, then let the panel cool for a full second (or more) between tacks. This way, the high heat will burn both panels cleanly, with less grinding later. The pause time will let them cool to reduce warpage. You'll also have to jump around the panel while welding to keep the heat out of any particular spot to minimize warpage.

The lip inside the quarter is sealed with seam sealer to keep the moisture out. We're going to be posting that in a the final bodywork video coming soon.

Kelle has some tips for getting women involved in these builds.. I'll defer to her for that advice.

Your Olds looks cool and is inspiring. We're certainly not on an unlimited budget by any stretch, so we're playing it safe to make sure we do this one right the first time.

The latest news is that the turbo mount is all fabbed up, and we've got a pretty trick scheme to finish the exhaust plumbing. We're waiting on a few parts and a suitable intercooler, but we've got some video to post soon.

The engine is going to be built by Bill Trovato at BTR Motorsports, and we're obtaining the last few items to finally put this thing together. Olds parts don't fall off trees like Chevy stuff does, so it's taken some time.

We're also installing an ISIS wiring system in the car, which is a new experience, but extremely cool. The ISIS system is going to allow for lots of trick features beyond the original design, and it's lighter and safer as well. Cool stuff.

Thanks for posting the video!

Our Olds is going to be powered by a 400 + cubic inch, FAST fuel injected , Bullseye Power Turbocharged Olds engine built by BTR Performance (http://http//www.btrperformance.com) , which means it's going to make alot of power. It also means the car is going to need a stout fuel supply to keep up with the engine. Today, we're looking at the components of our FAST Fuel System (http://fuelairspark.com/) including the fuel pump, filters, regulator, y-block, and all the included wiring and fittings. We're also taking a sidebar to explain the mystery behind AN and NPT fittings and what those "dash" numbers mean.

Glad you dug it, Ze... the Cragars are purely roller wheels while we put this car together. It's running Baers all around with a Hydroboost from Hydratech. It definitely will NOT have a stopping problem!

Post by: ZeGerman on May 25, 2009, 03:55:25 PM

Yeah, I figured the Cragars were just for moving it around the shop.

Just out of curiosity, which Baer kit did you choose? I know the "Serious Street" kit is the one that Baer recommends for muscle cars if stock wheel size is being retained. And although I presume you'll eventually choose a larger wheel size for the S71, I don't imagine the Cragars that are temporarily on it are much larger than stock, yet the Baer brakes still fit underneath.

Title: Re: 1971 Oldsmobile Cutlass "S71"
Post by: Kevin O on May 25, 2009, 06:42:13 PM

I don't recall exactly what Baer kit this is off the top m of my head, but the 15" wheels only fit over the rotors & calipers in the rear, the fronts to not clear the calipers with 15". But we're running larger wheels on this car, so it won't be a problem. I think these are 13" rotors in front and 12" in the rear.

Hi Kevin and all at the shop.
Have been folowing the progress of the olds for some time now and shes looking mighty fine.
spotted on U Tube your video on making use of what you have re holding the crossflow pipe from a magna flow exhaust whilst it was cut and welded and metion was made of the cutlass.
Do you intend to run all the exhaust from the turbo down one side of this system? If so will that not create massive back pressure?

Title: Re: 1971 Oldsmobile Cutlass "S71"
Post by: Kevin O on January 19, 2010, 07:16:42 AM

Hey Redneck,

The S71 exhaust comes out of the turbo and splits at the MagnaFlow "X" into dual mufflers with dual outlets, 3" tube. It's a pretty typical way to exit a single turbo exhaust system, and while there will be some back pressure, the MagnaFlow mufflers are a straight-through design which will keep the path as open as possible. If this were a race car and not intended for street use, we may run something different, but we think this is the best mix for packaging, power, and sound levels. We'll have more on that posted here soon!

This is great stuff! It makes me want to start working on the stroker motor I have sitting here for the 68. 467 CI of Pontiac power with a big a$$ roller cam in it. I got it from a guy who put the short block together 10 years ago and never finished it. I figure I will need to take it alll apart clean it hone and re ring it before I can use it. These videos are just the ticket.

Kevin,

How much for the video plus shipping? This is too good not to have as a reference for future builds.

Chris,

We feel the same way, nobody should build or have an engine built without watching this series. Next update later today!

You can order one here : www.v8tvshow.com/enginedvd (http://www.v8tvshow.com/enginedvd)

The shipping depends on the delivery address, but the average total is around $32.00 shipped.

Thanks!

Yeah! I'm dying to see this engine (& car) come together (especially since it is sooo similar to one I'm doing).
Planning to buy the full video too.

One question though, what ever happened to the wheels for this car?
I think I remember seeing something about 17" versions of the Olds Rally wheels being made? any info on those?

Title: Re: 1971 Oldsmobile Cutlass "S71"
Post by: Kevin O on August 22, 2010, 03:22:40 PM

The wheels have been like chasing a ghost for this car. The designs were made, but then the manufacturing never came through. The plans were sold, then the new company didn't make them either. They would be cool, but I guess they take so much billet material to create the deep face details that they would be outrageously expensive to make. That's the last I heard, anyway.

Title: Re: 1971 Oldsmobile Cutlass "S71"
Post by: Kevin O on May 22, 2011, 08:20:18 PM

We posted the basic install plan for the Bullseye Power (http://www.bullseyepower.com/racing.asp) turbo install on the S71, and here's some of the photos of the process.

After evaluating the underhood location options, Brett Evans from Outlaw Turbo Motorsports (http://www.outlawturbomotorsports.com) determined the best locale for the 75MM turbo would be on the passenger side behind the headlights.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.21.09s_010.jpg)

As shown earlier, here's the beast. These things are not light, thanks the large cast iron turbine housing. Because of this, we're going to build a frame-mounted stand to support the weight. Some choose to mount the turbo on the exhaust manifold, but we wanted to "over do" it, so on the frame it goes.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.21.09s_014.jpg)

One of the features we liked about the Bullseye Power unit is the extended tip design of the turbine. This effectively increases the size of the impeller while keeping the same external dimensions, allowing more power from the same size unit as other 75s.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.21.09s_023.jpg)

One tip Brett shared is the "knife edging" of the flange, smoothing the entryway for the exhaust. This was smoothed with a die grinder lubricated with some Tap Magic cutting foam.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.21.09s_047.jpg)

Brett and Nick worked up a temporary base using some 4" square tube steel to help conceptualize the mount base. The turbo will be pitched slightly for packaging reasons, and angled so ease the piping in & out of the turbo.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.21.09s_059.jpg)

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.21.09s_061.jpg)

Title: Re: 1971 Oldsmobile Cutlass "S71"
Post by: Kevin O on May 22, 2011, 08:34:06 PM

Construction starts on the mount. Brett cuts 3 sides from some sheet stock, and hammers them to form the desired shape. Then they are tack welded together for test fitting.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.23.09s_002.jpg)

Some vise-grip clamps and welders magnets hold the pieces in place while Brett tacks them with the HTP MIG 200 (http://wwww.usaweld.com) MIG welder.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.23.09s_023.jpg)

At this point, Brett is still considering the 4" base material, but this would eventually change to a cleaner design. However, that comes later…

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.23.09s_040.jpg)

The 3-sided stand is cleaned up on the Multitool belt / disc sander. Other essentials include ear plugs and Doritos, along with a stocked fridge.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.23.09s_041.jpg)

Here, the turbo flange is tacked in place.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.23.09s_056.jpg)

Title: Re: 1971 Oldsmobile Cutlass "S71"
Post by: Kevin O on May 22, 2011, 08:50:24 PM

Once happy with the shape, Brett welds the 4th side.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.23.09s_070.jpg)

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.23.09s_067.jpg)

Next up is a little grinding and sanding with some 3M abrasives, and the piece starts to look nice.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.23.09s_077.jpg)

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.23.09s_079.jpg)

Next, Brett tackles the challenge of routing the exhaust gas into the turbo. He starts with a section of mandrel bent 3" tubing and the chop saw.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.23.09s_087.jpg)

Here's the cut piece of tubing entering the turbo flange.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.23.09s_094.jpg)

Brett notched the turbo stand to accommodate the feed tube.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.23.09s_103.jpg)

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.23.09s_112.jpg)

Brett spent some time welding the piece, especially joining the oval tube to the turbo flange. Much time was spent filling the gaps and filing the edges for a smooth airflow path into the turbo.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.24.09s_004.jpg)

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.24.09s_014.jpg)

Title: Re: 1971 Oldsmobile Cutlass "S71"
Post by: Kevin O on May 22, 2011, 09:20:17 PM

Next, Brett revised the base mount to use a plate welded to the frame with 3 mounting tabs with lock nuts welded inside.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.24.09s_020.jpg)

TIG welding the mount

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.24.09s_025.jpg)

The turbo and mount in place on the frame.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.24.09s_028.jpg)

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.24.09s_038.jpg)

Checking hood clearance, and all seems to be in good shape.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_02.24.09s_044.jpg)

Brett uses a 5" v-band flange and section of 45-degree mandrel bent tube to aim the exhaust out of the turbo. He then welded it to a 5" to 3" stainless cone to taper the exhaust to the downpipe which connects to the MagnaFlow (http://www.magnaflow.com) exhaust system.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_03.18.09s_002.jpg)

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_03.18.09s_009.jpg)

Next, Brett fabled up a new cross pipe which connects the driver side exhaust manifold to the passenger side to supply to the exhaust to the turbo. The Olds 350 has a provision in the passenger side manifold to connect the two sides together for the single pipe exhaust cars which we took advantage of.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_03.19.09s_001.jpg)

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_03.19.09s_006.jpg)

Radiator installed, checking for clearance on turbo outlet. Hmmm.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_04.21.09s_005.jpg)

Then the big brown truck delivered the giant Bell (http://www.bellintercoolers.com/) intercooler. We were impressed with the quality of the fabrication, and they are known to offer substantial air charge cooling with minimal pressure loss.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_10.05.09s_044.jpg)

We chose the largest core we could stuff in the nose of the Cutlass, and this one measures 4.5" inches thick.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_10.05.09s_048.jpg)

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_10.05.09s_053.jpg)

We had to cut the main vertical support apart to accommodate the intercooler, and here, Brett contemplates the entry / exit strategy. The intercooler fit better inverted, so he decided to move the turbo outlet to match.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_10.05.09s_056.jpg)

Title: Re: 1971 Oldsmobile Cutlass "S71"
Post by: Kevin O on May 22, 2011, 09:30:51 PM

The boost levels will be controlled with a Turbosmart (http://www.turbosmartonline.com/) Pro-Gate 50 wastegate. This is plumbed inline with the turbo on the exhaust side, and dumps extra exhaust heat & pressure at a pre-determined pressure level.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_10.05.09s_026.jpg)

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_10.05.09s_037.jpg)

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_10.05.09s_043.jpg)

In this shot, the protruding tube is the wastegate mount, and the longer tube is the feed into the turbo.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_12.12.09s_011.jpg)

Wastegate installed, ready for wastegate exhaust tube fabrication.

Meanwhile, Nathan jumped on the S71's bodywork. Our buddy Mark Poole roughed-in the body filler on the car, and Nathan completed the process of refining all the surfaces to make for a super-straight finish. Here, the S71 is all masked off ready for a coat of Standox sprayable polyester filler.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_06.30.09s_002.jpg)

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_06.30.09s_006.jpg)

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_06.30.09s_009.jpg)

Being sprayed-on, the Standox polyester goes on without any pinholes, and fills all the sanding scratches left in from the filler stages.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_07.01.09s_016.jpg)

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_07.01.09s_017.jpg)

It lays out thick, but sands off smoothly.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_07.01.09s_020.jpg)

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_07.01.09s_024.jpg)

Once hardened, Nathan sprays out a layer of guide coat before block-sanding the S71 straight. The guide coat allows him know easily spot the low and high spots while sanding, as the guide coat comes off revealing the white polyester.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_07.01.09s_035.jpg)

The original GM fiberglass Outside Air Induction (OAI) hood was repaired and bodyworked straight, and receives its polyester coats off the car.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_07.01.09s_048.jpg)

Hood and decklid in polyester.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_07.01.09s_058.jpg)

We added a reproduction rear wing from YearOne (http://www.yearone.com). It's a fiberglass piece that was pretty nice out of the box, but we also bodyworked it and sprayed it with polyester to perfect it's shape.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_07.01.09s_060.jpg)

Block sanding the polyester… Nathan runs on 44 ounces of go-juice at a time!

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_07.02.09s_007.jpg)

After sanding, the S71 awaits primer.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_07.04.09s_004.jpg)

The backside of the rare and fragile S71 OAI hood was stripped using an Eastwood (http://www.eastwood.com) dual blaster, which blasts media from two different tanks allowing an abrasive media in one tank, and a less abrasive baking soda on the other side. The soda blasting revealed the original fiberglass, and the abrasive aluminum oxide quickly stripped the rust from the steel understructure.

Post by: Kevin O on May 23, 2011, 07:04:40 PM

After the poly was sanded, Nathan applied several coats of DuPont Hot Prime and wetsanded that down in preparation for color. If you watched the video on the fender test panel a few pages back, you know the color is DuPont Hot Hues Warp Speed Blue, an awesome mix of vibrant blues with pearls and metal flake elements that really light up in the sunlight.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_11.19.09s_011.jpg)

This time, Nathan sprayed color on the inside and outer surfaces of the parts, and then checked them with a 3M Sun Gun to make sure the coverage was complete and the pattern looked good.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_06.18.09s_021.jpg)

Then, the "jamb" areas and panel backsides were masked and prepped for a coat of HotClear clearcoat to make them shine.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_11.19.09s_009.jpg)

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_11.19.09s_017.jpg)

Smaller parts were cleared in their entirety.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_11.19.09s_004.jpg)

Next, the body shell was rolled in for a coat of Hot Rod Black satin on the dash, firewall, and interior details.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_11.25.09s_013.jpg)

Once blacked-out, the body shell was sprayed in Warp Speed Blue, and the jambs cleared. The outside will receive another several coats of color and clear once the car is reassembled to minimize the risk of chips and metallic pattern mis-matches.

Back on the frame, the S71's interior was wrapped in Hushmat, a temperature and sound blocking product designed to deaden the noise and make the car more enjoyable to drive.

We're going to be running some Glasstek fiberglass bumpers on this car, so Nathan spent some time doing some bodywork on them to make them fit nice and tight.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_09/images/S71_12.15.09s_002.jpg)

The front bumper was very lightweight, and more of a race car part than a street car piece, so Nathan made a mold from the original steel bumper's turn signal housings and made 'glass versions for the new bumper.

WOW! I been waiting for more news on this project, and it is looking great!
Looking at the pics, I do not see much room on the pass side for an A/C compressor.....
Is this car not going to have A/C, or are you locating the compressor on the other side?
Can't wait to see more!

Good call on the fiberglass bumpers. I am planning the same body mods for my Olds. I plan to paint them the body color.
I've also been toying with the idea of building a lightweight rad core support, as the original old GM unit seems to weigh a ton.

Alain,

This car is not running A/C at this point. A compressor could be added to the driver side with a custom bracket, but we're out of space on the pass side.

The bumpers will be painted in ALSA's MirraChrome (http://www.alsacorp.com/products/mirrachrome/mirra_prodinfo.htm)for a 70 - 80% reflectivity, they should look like aluminum when done.

Here's a demo of the product...

Post by: Alain V. on May 26, 2011, 04:42:09 AM

Looks interesting. I must be living under a rock (or in Kansas ;D ) because I've never heard of this process before.

One more question. Are you guys going to use a flex pipe somewhere or a softer mount for the turbo to accomodate for engine movement?
It seems that even if you use solid engine mounts, since the turbo is mounted to the frame, there is going to be some movement which could cause trouble with cracks in your exhaust feed tube???

Title: Re: 1971 Oldsmobile Cutlass "S71"
Post by: Kevin O on May 26, 2011, 06:49:48 AM

The engine and turbo are all solid mounted to the frame, so we're not anticipating very much movement. There is a very slight amount of "give" in the exhaust system as well, so we hope to not have any issues. The transmission is on a urethane mount to protect the aluminum case.

We decided to run an Edelbrock intake elbow on the EFI system, so some preparations needed to be made to make sure it cleared the hood.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_10/images/S7102.18.10s_005.jpg)

We ended up milling the top of face off, and re-drilled it to accept a Holley (http://www.holley.com) LS style throttle body rather than the Ford style. This would gain us some room under the hood.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_10/images/S7102.18.10s_008.jpg)

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_10/images/S7102.18.10s_014.jpg)

The BTR (http://www.btrperformance.com) built engine is running a magnetic pickup mounted on the crank snout for timing, which means it adds 3/8" of an inch to the front of the engine. We had to re-work all the brackets to extend the pulleys forward 3/8" to make them line up. Here's the alternator bracket.

Before:

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_10/images/S7106.10.10s_002.jpg)

After:

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_10/images/S7106.10.10s_023.jpg)

Hard to tell what happened, but it's been cut, stretched, welded, and ground back into shape.

Here, the BTR Performance (http://www.btrperformance.com) engine is installed. Note the reflector ring on the crank. The revised alternator bracket is installed, but that would eventually change again. Note the spacer on the steering pump bracket, and the beginning of the fuel system in place.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_10/images/S7112.04.10s_001.jpg)

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_10/images/S7112.04.10s_006.jpg)

We hate to drop nuts and bolts, so we try to weld nuts to the backside of brackets and stuff when we can.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_10/images/S7112.04.10s_011.jpg)

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_10/images/S7112.04.10s_014.jpg)

And then to attach it to the original alternator support bar.

(http://www.v8tvshow.com/images/stories/71_Oldsmobile/S71_W_10/images/S7112.04.10s_017.jpg)

Just about ready for prep work and powdercoating.

Title: Bullseye Power Turbo Video Install Part 2 - S71 Olds Project V8TV
Post by: Kevin O on June 24, 2011, 05:14:42 PM

In this chapter, we're fabricating the hardware and tubing needed to install the Bulleseye Power 75 MM extended tip turbo from Outlaw Turbo Motorsports into our 1971 Olds Cutlass S71 project. The install required mating the stock exhaust to the custom turbo mount, then sending the exhaust out the custom MagnaFlow 3" dual exhaust system. Other tasks include installing the large Bell intercooler in the nose of the car, installing a TurboSmart Race Port 50 wastegate, and fabricating all the tubing to manage the airflow. In the next chapter, we high-temp coat the parts, install the TurboSmart blow off valve, complete the tubing, and address the cooling and oiling systems.

Alain,

This car is not running A/C at this point. A compressor could be added to the driver side with a custom bracket, but we're out of space on the pass side.

You'd have enough room on the passenger side for an AC compressor if you set it up like a factory Cutlass AC is done: the alternator goes on the driver's side, above the PS pump. The PS pump moves down a bit, looks like. I haven't looked closely at non-AC setups other than to note the alternator being where my AC compressor is. I live in TX, so the majority of Cutlasses I see have AC (including mine), as you might imagine...
(http://wright-here.net/gallery/d/2039-2/DSCF0194.JPG)
Not the best picture, but you can see the AC and alt, at least.

Neat idea. I'd like fiberglass bumpers myself, but since my car is black, I think body color is the way to go. Mirrachrome is a good alternative, especially if you're trying to stick to a stock look.

Post by: Kevin O on July 22, 2011, 04:48:51 PM

Thanks for the pic. We're REALLY out of room on the pass side because of the turbo and tubing... the alternator barely fits on that side. The alternator rides right in front of the valve cover, so even if we moved it to the driver side, we'd still not have a deep enough hole for a compressor on the pass side.

What else have you done to yours?

Title: Re: 1971 Oldsmobile Cutlass "S71"
Post by: 70OldsSportsCoupe on July 24, 2011, 01:26:11 AM

Well, just recently I came in to some cash, so I went through the whole suspension. Basic stuff, not major high dollar tubular everything (that's later) but polyurethane all around, Hotchkis springs and Edelbrock IAS shocks (in the "classic" grey rather than red.) Blasted and painted all the bits. Edelbrock tie rod adjusters, and just generally made sure everything was up to snuff. I installed the same Magnaflow exhaust (in 2.5") you guys used, but still duals all the way of course. I did have to shorten the mid section; apparently, Magnaflow never fitted it to a car with a TH400 (or 700-R4 or 200-4R) where the crossmember was in the rear position. It doesn't fit out of the box like that. I was a little disappointed in a $500 exhaust I had to modify so much to make fit, but everything else went together almost painlessly.
Engine's mostly stock, but it was the 310-horse version to start with. Mild Mondello cam, Edelbrock intake, Hooker headers. Still running the Q-jet, until I build up my MegaSquirt EFI system. Installed a 200-4R same time as all the suspension work. Works OK, but I need to put in lower rear gears (highway-friendly 2.7x gears are a bit tall for the OD...)
The irony is that I finally got all the mechanical bits up to snuff, and I can't afford gas for it. 10.25:1 factory compression says I must use Super Unleaded, and it only gets about 13-15 MPG (before, with the TH350 - haven't had a full tank to check mileage with the OD!)
It looks rough, but the chassis and drivetrain are solid. I guess it's time to start on the bodywork now... :D
Eventual plans are to turbocharge it, which is why I'm watching S-71 closely. I wanted to go with two smaller turbos tucked a bit more forward on each side to avoid having to ditch the AC and power steering (I live in Texas - AC is NOT a luxury!) and maybe two smaller or siamese intercoolers. I'll have to build a different engine, though. 10.25:1 + boost probably would not fare well.
My car is raggedy-looking, but I love it. I've had it for around 15 years now. Someday it might look as god as S-71. I like the blue you're using, but mine was originally silver (black, now) and I think I'll go back to that eventually.
Keep up the good work!

Post by: Kevin O on August 16, 2011, 04:57:16 PM

In this chapter of our S71 Olds build, we are completing the install of our Bullseye Power 75 mm turbo, our fabricated turbo piping, Bell intercooler , and the Be Cool Radiator . All of the exhaust tubing and turbine housing parts were coated by Extreme Powder Coating using their 2200° high temperature black ceramic coating to keep them looking new. The charge air tubing was painted with Eastwood's high temperature Nano Ceramic engine paint, which is a very durable paint suitable for parts reaching regular engine temperatures. The be cool radiator module encompasses a pair of Spal electric fans, and Be Cool guarantees it to cool engines up to 1000 HP. We installed a Turbo Smart Reaceport blow-off valve inline with the air intake to help keep the turbo spooled-up during shifts. To help reduce underhood air temperatures and to make our turbo system more efficient, we installed a DEI Titanium Turbo Shield , which is made from lava rock strands that can withstand temperatures over 1800°. We also wrapped our turbo exhaust with DEI Titanium Exhaust Wrap to keep the hot exhaust gas in the tubing and underhood temperatures down. A K & N air filter and various silicone connectors from IntakeHoses.com completed the intake tubing. In the coming chapters, we will complete the ISIS Intelligent Multiplex wiring system install and FAST Fuel Injection installs before firing up the S71 Olds!

Anything new on the olds yet? I'd really like to know what wheels you ended up going with.
I'm still hoping someone out there will eventually make either a steel or alum version of the SS II wheels in 17-18 inch.
The original GM design just looks soo good on the cutlass that I just can't seem to bring myself to "like" anything else.

As for the wheels, we're eyeing the new Rushforth Salt Shakers... with the centers painted, they'd have a very similar vibe as the SSIIs. What do you think?

It is an American Racing "Hopster" with a little gold paintwork and the center cap photo shopped with an olds emblem.
I am definatley going to look closer at this as it really looks like a modern interpratation of the SSII.

I think they can be custom ordered with varying backspace up to 20 inch wheels.
I will send you a PM with a link to the site where I found this info, as it may be of help.

You are right about the fenderwells on the 70-72 Cutlass, they can take alot of tire,,,,if I remember right 27 inches tall seems to be the magic number to maintain a good look.

Well, that's pretty stupid. Buy a design then not make it. It's got to be frustrating for the dude that designed it as well. I remember following the threads on Protouring and such. He put a lot of effort into that design.

Title: Re: 1971 Oldsmobile Cutlass "S71"
Post by: Kevin O on November 30, 2011, 06:01:55 AM

He did put a lot of thought and time into the design. I think the issue was that the face of the wheel would have to be made from a very thick piece of billet, making them a pretty expensive wheel to make, and Bonspeed has not seen the demand for them. Most Olds enthusiasts seem to be happy with the stock wheels or lower-cost aluminum aftermarket wheels, and $3200+ for a set of wheels might be a tough price point for that crowd. I'm just speculating here, but that's the vibe I got.

Title: Re: 1971 Oldsmobile Cutlass "S71"
Post by: 70OldsSportsCoupe on November 30, 2011, 07:10:20 AM

Probably so. It might have worked better as a two-piece wheel.
Ah, well. I like my Torq-Thrust IIs well enough, common as they are. The Hopsters that Alain posted would look great with body color (Like the later SS II) instead of gold, as well, I think. There are several nice interpretations of the SS I, AKA the Magnum 500 out there as well, like American Racing's AR500 and NewGen's Classic Series Five Hundred (I particularly like that one.) I went with the TT IIs over them because a) I like a more "open" wheel, because I like the mechanical look of the brakes, and hope to have something worth showing off eventually, and b) I found the TT IIs in 17x8 cheap, with tires at a swap meet. :) I need to have them blasted or something, though, as the chrome is peeling from the aluminum. For the moment, it fits the generally ratty look of the car...
