turbo exhaust?, speed channel turbo exhaust on a corvette Options

[2bcelica]

i was watching the speed channel and saw that they installed a turbo into the back of the exhaust pipes on a corvette. it looked sweet and sound awesome when the test drove it. Imagine a Turbo in the engine bay and an additional turbo used for the exhaust - . If I remember correctly the turbo was adding near the rear bumper of the corvette and the end piece was the exhaust tip. Any one heard about this - it would be awesome on a celica

ive seen it on mustangs. and first heard about it on a Dodge ram....idk anything about moving the turbo to the back, but i wouldnt mind some insight as to why. (besides lack of physical space)

[JDcelica]

think of the turbo lag. omg!

[playr158]

They are called Remote mount turbos....they have been around for 3+ years

turbo lag isnt' an issue considering the velocity of the air. Lag is more due to the size of the turbo than the actual length of pipes.

But shoot have fun scraping turbo on the ground

that's retarded. i suppose that being able to turbo a car with limited a/m turbo support and a cramped engine bay is nice, but really.

how much fresh air can you possibly get to the filters when they're mounted behind the tail lights, way up inside the rear bumper cover? how serviceable is any of this stuff anyway? can you imagine having an oil leak or popping a coupler on that? that's gotta be louder than hell, too. looks like way too much work and money for what it is.

it's a clever idea i guess. i like how the outer two pipes of the exhaust are actually just screamers. the intercooler design is neat too.

other than that though....

Guy down here had a mustang gt running constant 13.20's in the quarter mile while N/A. He put a turbo from an airplane rear mounted like this and ran 17.40's hahaha. Needless to say he took them off. It sounded like a jet was coming down the road but it was barely moving. I coulda beat it in my old celi.

there is lag in a sense
the longer piping will cause more of a pressure loss that will seem like lag.

good idea for cramped space

Could be stolen so easily though.

Thats deffinitely an interesting idea, i saw it in a magazine once. There are definitley pro's and con's to the set up. Im sure lag will be an issue to some extent, not really because its far from the exhaust man, but because its far from the intake manifold. I could imagine it takin a sec to refil the charge pipe after the BOV/BPV has ejected some air. - either way, a turbo is still a turbo wherever you mount it, and if it generates boost, (even if its laggy) it will still create hp assuming you tuned the motor correctly.

I see it as a good way to hide a turbo setup, especially here in cali where cops are constantly popping hoods. Just hide the charge pipe in your stock plastic intake pipe. As far as air getting to the filters like Uberschall was concerned about.... you dont have to mount it like they did in the vette, you could route it however you would like but i think the issue would be finding a spot that gets air but isnt volnerable to water being sucked in too easily.



There's my though on it, dont know if anyone cares or not , but it would be interesting to see if someone were wiling to try it out.

[uberschall]

it could be done for a quick and dirty +fte setup. you might not even need an intercooler depending on where you route the charge pipe. it would probably work best with a recirc.

it almost makes sense for a v8 car because there isn't alot of ral estate under the hood for turbo manifolds, turbos, and ic piping. on the celica, there's so much extra space and compatible parts that this might actually be harder that just using a 3s manifold and an fmic.

any cop worth his badge is going to know what a bov sound means, and with the screamers on the wg's of the vette setup, they'd surely know you had a turbo somewhere on the car by the noise alone. the sound clips on the sts site don't seem to work for me, but i assume it's pretty noisy.

eggman, how do you tune this engine compared to a traditional turbo set up?

[tim86]

wow thats pretty sick... you cant even see the turbos from the rear... id really like to hear how it sounds on that vette

[SlickRick]

yeah its just as effective as a regular turbo bcuz since it is away from all the hot engine components it run about anywhere from 50-100 degrees cooler, and lag is not as much of and issue as you think, as long as u really make sure all ur connections are right. also the install is greatly simplified. But right now i have only seen them for high end domestics. but there is STS universal system i think. i think a remote set-up used in conjuction with a variable geometry turbo would be a tremendous set-up. the colder charge more than makes up for the small lag, in fact the air is so much more cold and dense that u can a few PSI lower and still get the same HP #s as a normal set-up.

[eggman40]

eggman, how do you tune this engine compared to a traditional turbo set up?

Im no expert, but i would assume you would take the same steps as you would boosting any other N/A motor. For example the a 5sfte setup. It starts off as a N/A but once you start adding boost to it, you need to start by changing MAP sensor, maybe add piggy back of some sort, fuel supplements (new pump, maybe injectors, depending on amount of boost) intercooling if needed. and many more



A motor is NOT gonna care where the turbo is mounted. All it knows is that there is more air being pushed into the intake manifold than usual and if you dont tell it what to do, its gonna destroy itself, depending on the amount of boost this rear mounted turbo setup could generate this will be an issue.



Again this is based on my intermidiate knowledge and this rear mounted turbo is a new concept, so if anyone disagrees with any of my statements fell free to say so, thanks!



im off to celebrate my B-Day! the big, two-one!

I'm sorry, I misread, I thought you were saying that you would have to tune a turbo set up w/ the turbo in the exhaust differently than if you had the turbo at the manifold

No problem man.

[urbandork]

ive seen that set up on a integ before. personally im not to crazed about it... althought it must sound bad @$$ fo sho
