Hey guys,

where cna I find those turbo exhaust kits for  my '77, I seen the Boyd Cottington show and htye did it toa  '63. Thanks,

Louis,

 That wasn't a kit. That was being custom made. Pretty slick setup. But I don't think that even with both of our incomes combined, we could afford something like that. LOL. But apparently the car owner has plenty of cash. L8R

about the closest thing I can think of to that is banks twin turbo kit. but that kit cost about $25K Banks Twin Turbo Chevy 350

There is actually a company making a rear mounted turbo kit.  The company is called STS.  This kit is great for crowded engine bays and supposedly easier to install.

I don't think our C3's would be a good candidate.  Mainly because the turbo has to be mounted in the rear up around our axle.  With all our iRS suspension I don't think there would be enough room.  Even if you could mount it there has to be enough room under the car to run an additional air tube up to the engine compartment to expell the boost from the turbo into the engine.  That means you would need three pipes under the car.  In most cases where this kit is being used the turbo is being spooled off of a single pipe Y together off the headers.  This would mean only two pipes would be required under the car.

The last issue to contend with would be Heat.  Obviously mounting a turbo at the rear of our C3's mean the turbo would be up against the fiberglass.  And incase your wondering.  Resin and glass can catch fire it subjected to too much heat.  Somehow a heat shield would need to be created.

I'm not saying it can't be done, anything is possible with enough engineering, but at least this would be a kit that could possibly be modified to work.

I believe it could be accomplised by eliminating the spare tire carrier and mounting the turbo where one of the mufflers use to be.  This would allow you to run the boosted side of the turbo across the rear, back up where the other dual exhaust side used to be up to the engine compartment.  You would also need a specailized blow through carb.  I have worked with the Carb Shop in ontario and they have mastered these types of carbs and I would give a 100% recommendation to use this piece rather then trying to addapt a different carb.  They spent count less hours of development making these carbs in conjunction with ATI procharger blow through centrifical setups.

I'm working on an engine project right now that I', heading up for 5.0 Mustang Magazine that will be a 427 351 Windsor based Ford Stroker that will be using a Procharger blowing through a carb that should make a 1000HP on pump gas running an intercooler. We wll easlily have 12K just in the parts alone.

Thats not saying you should try to make this type of engine or power.  You would have to heavily modify the rest of the car just to handle that type of power.  If you had an engine that was making 375 Hp I would add 7 PSI boost and it would push that number up to 525HP.  That would be reasonable.

rear mounted turbos are kind of strange to me since exhaust gas loses alot of its energy by the time it reaches the back of the car. (velocity and temperature are way lower, plus the compressed air has to travel all the way back forward to the engine, more energy loss. It goes against the logic of thermodynamics for me. Unless I was very strapped for engine compartment space I would try to mount the turbos as close to the exhaust valves as possible to maximize turbo efficency and performance. But maybe those guys who made the kit, overcame those problems with the turbo design. My two cents. Tumarr38399.3814467593

Hey guys thanks but neither kit will work anyhow. The companies bot said that they are for EFI systems not carburated systems.

Is there any other Turbo system? I don't want to use NoS I view it as un-natural and wrong.

I was thinking of upgrading to a Holley Blue Electric fuel pump, with a Holley fuel regulator to get 14PSI of fuel.

I was also thinking some World Brand alumninum heads with a 64CC cahmber size, and 220CC intake runners. I would still keep my precision roller rockers from Mid Lift, and my Edlebrock 1406# card and 27012 intake, and my hedman elite headers. How much extra HP you think I'll have? right now this is the current setup:

Thanks guys,

p.s. can you guys look at my check list:

http://fattyslims.com/vette/vettechecklist1.doc and make sure that my fan kit, and stuff is all correct?

Thanks again guys

As ive recommended 20 times before..  get the holley blue pump... but you cannot use 14 psi on your carb.  youll use the regulator to take the pressure back down to 6.5

14 PSI is the maximum Pressure a blue pump is capable of making.  I believe the max pressure you can run on an edelbrock in 4.5 to 5 PSI. 

The carb and intake you have will not support a 220cc head.  In your current setup you would be better off with a head in the 180 to 190cc range.

Also that carb and intake I would not use on a turbo or supercharger set up.  My two cents.

If you want to run a supercharger then go to www.procharger.com

Get of their blow through setups.  You may have a hard time getting it mounted because our engines accessories are almost perfectly inline with the A-arms which may get in the way.

You will want to get a carb for the blowthrough from the carb shop in Ontario, Ca. www.customcarbs.com

Just be prepared to spend lots of money on the fuel system upgrades and rear axle upgrades.

Just and FYI.  Adding nitrous is no different then adding a supercharger.  Both are means of gettng more air/oxygen into the engine so the engine can burn more fuel.  While one is on all the time, nitrous is not.  Both are artificial means of making power.  Ones just a whole lot more expensive to do then the other. 

 

 

 

Dude, Matt, seriously. Now you got me scared. I want to add this turbo kit on, but now you are making me think that I’m going to blow the engine up. I think he said it’s only 6PSI of boost. To give you guys a low-down on what happened yesterday... I came home from getting my hair cut, only to find my dad on the phone with a dude named Brady. They called me back from STS Turbo. They only have kits for EFI applications, not carb. They do have a kit they are working on for carb applications but it’s not totally out yet. They put it on a newer car, but not a car such as a '77 Vette, and since you don’t see many of our cars around anymore they won’t to put it on an older car. They guys said that when we were ready he'd give it to us for $2,000. He said that the jets in the carb would have to be replaced with the ones that come in the kit. Matt you said:

"Also that carb and intake I would not use on a turbo or supercharger set up.  My two cents." why is that? I mean my dad told them what we got, and the guy said it should work, and he would help us install the system on the phone, the only thing he said we would need to do is replace the jets with the ones from the kit. But also just to be safe I want to upgrade to the electric fuel pump. If I knew I was going to do this I would have just got it already. I also am confused as to why I can't use a set of 220CC heads? WHy do I have ti use 180-190CC? WHat is the current size of stock?

Just look at these videos:

My Vette would be able to do that. :)

Lots of reasons I said what I said.

I would not run 220cc heads on a mostly stock setup.  Its over kill.  What you need to remember is just because it has big flow doesn't make for a good engine.  If the flow becomes too big, you can actually hurt your engine because you will actually slow down scavenging of the cylinders.  Basically hit can hurt velocity.

220cc heads would be fine with a turbo  or supercharger setup.

Performer intake is a dual plane mild intake.  It would be a mismatch to the 220cc heads.  Fine for a set of 180cc heads.

You should consider a performer RPM or an Air Gap for the 220cc Heads or even a single plane.

600 cfm carb will not be large enough to supply 220cc heads and will be a restriction on this setup.  Just an FYI that 600 cfm is a dry flow number.  This carb actually wet flows around 500 to 525 cfm. 

Blow through on a carb:  You are actually pressurizing the carb which is the opposite of what it was designed to do.  They were designed to opperate based on atmospheric pressure.  When your forcing air into the carb you are creating forces above and beyond atmospheric.  Therefore the entire metering is off on the carb.  The seals in the carb are not designed to handle this either.  Thats the reason I said to go to the carb shop for one of their blow through carbs and Carb Bonnets.  They have engineered their carb with 2000PSI throttle seals and pressure balance tubes to make it blow through friendly.  They are the only ones that have been able to do this correctly.

Blow it up:  Maybe!!!  Remember an engine is only as strong as the weakest part in the engine.  While you can run a supercharger on stock parts you have to be cautious about how much pressure you are using.  Build it for overkill and you will have no problems.
