STS turbo under a regal?

[1dollardog]

Has anyone ever done one of the STS turbo systems (or one like it) on a regal with a V8 or V6. That is the turbo system where the turbo is placed under the car usually in the place of the muffler(s) and the legnth of pipe from the turbo back to the tb usually acts as an innercooler. I'm sure it would save some space under the hood if that is an issue. I was just wandering if it had been done on a regal.

Im sure it can be done, but I do not think anyone has actually gone with a rear mounted set up. All of them I've seen are underneath the hood. For some reason most shy away from the rear mount setup, even though they have been proven to work well...

There is just so much space under the hood that anything short of Twin mid frame turbos on a BBC will go in with little to no issue. I considered a in-trunk mounted turbo at one time. It would have worked just fine , just lots of labor involved.

I think the biggest downsides are the length of the plumbing and the fact that a lot of exhaust heat is lost between the engine and turbo.

I could see a problem with the length of the piping and inceased turbo lag, however it also should act as its own innercooler and cool the air some as it travels back too the engine. As for the exhaust cooling before it gets to the turbo, wouldn't that be a good thing? I'm sure I don't know the science behind it but I would think that it would be good for the turbo to be cooled somewhat. Besides I'd say it wouldn't cool all that much.

Heat=energy, long pipe to turbo means cooler exhaust. Longer pipe from turbo to engine=cooler air. + and -

I have seen a few turbo kits on vettes hear at the dealership with the sts kits on them. They run a small twin setup and they seem to run well. The trubos are small enough that there is no noticable lag. Then I have another costomer that comes in with a really nice twin setup from HP. It has them hidden so well you can even see them with out just following the exhaust. The new owner put 775 to the wheels with a pair of 60-1's. It is a very clean red c5 Z06. Super stealthy!

I guess I've owned a hot air GN too long. Using the heat=energy formula my car should be in the 10's.lol. Seems like the hotter the turbo the more slugish the engine but I guess this is primarily because it is also heating up the intake air and losing air volume. I wander what the ideal "exhaust gas temp" at the turbo should be for max performance from the turbo? If the turbo is cooler does that mean that it is going to spool slower than it would if it was hotter?I guess I just don't get it.
