Where could i find a Turbo that attaches on to your muffler...

[corkscrew]

I saw one on TV the other day and am very interested...thanks for your help

[neonlarry]

here is one place:

[corkscrew]

Anywhere else guys?

Contact forum member Capt Kaos. Chris is a dealer for the one above...

Im interested in seeing this forum play out; being ignorant in such matters it seems to me "how do you suck instead of blow?" would you need a new cam to have an "exhaust turbo" seems to me that you would but my knowledge is limited.

[Longhorn Man]

Turbos are run by the exhaust, with the exception of some new belt driven turbo...which is basicly a supercharger then.
These being discussed here are just mounted under the vehicle instead of right off the exhaust manifold.
If you have room under hood for a traditional turbo, then there is pretty much no advantage to this under body type.

[GREASEMONKEY72]

the turbo style ones run by the belt are prochargers and are a mix of a supercharger in the turbo form and as far as the turbos under the car or at the back you will have more lag vs being under the hood and closer end result is the less lag the sooner the power hits

[Longhorn Man]

and less boost period since the exhaust has cooled quite a bit and has less force to it. More high pressure compressed air leaks, esp in the cold weather too

[Pl4yboy]

Yeah you can only run 6-8 #'s of boost on these...

[pharcydekm]

Now I speak from zero experience with these turbos but... You can run up to 15psi of boost and from what I have heard the lag is not an issue. I too would like to see how this thread goes and would love to hear someone chime in that has used one or at least been in or seen a vehicle with one.
I saw an episode of Horsepower TV that they intalled one on a C5 Corvette. It looked awesome!!!

They are still very new so I can see how people would be cautious on throwing down the cash for it.

It seems like a lot of money for the "universal system" from STS. $3k gets you a run of the mill diesel truck turbo, a pop- off valve & trinkets, an oil scavanging pump that can be bought here http://www.rbracing-rsr.com/oilsystems.htm for $530 (which includes the "super" pump & check valves). Sure, the trinkets add up, but not that much. Buy the oil pump from RBR, pick up a turbo from a diesel shop, get the pop-off on ebay, have your oil lines made locally, buy a power relay & make the simple wiring yourself. I think all this could be bought for under $1500. Then the $1500 you saved can be used for the exhaust work/ mounting & air piping.

[Pl4yboy]

Maybe I'm wrong about the boost. But I did hear that somewhere.

[GREASEMONKEY72]

nice camaro

[special-K]

Is there a slight chance water might find it`s way into the filter on the red car???
With these under body turbos,what about wastegate controllers?Under the hood they have problems hanging up,already.I can imagine road grime,oil,and corrosion would surely play havoc on this component.

IMO, the lag is going to be increased with the turbo back that far. You have the intake at the rear now and you are going to pressurize the pipe that runs all the way back to your carb/throttle body. The shorter that plumbing is the better, plus it will be less prone to boost leaks.

Agreed on the longer pipe more chance for leaks sid eof it. But... on the boost once the pressure is there it is there. In my mind it would be like an air hose connected to an air compressor if it is 100psi 2" from the compressor it is going to be 100psi 10' from the compressor.

But your air compressor doesn't put out 1200° air that cools to 100° in that 10'. The airspeed is a lot less 10'ft away from the manifold.

[special-K]

Cooler air is a good thing.That`s why there`s intercoolers.Cooler charge air allows higher boost with tolerable EGTs.Longer tubing does not effect charge air pressure.

[GREASEMONKEY72]

cooler air also makes more HP, but IMO theres just alot more risk just driving normaly on the street with the turbo sitting under the car and the airfilter being right there next to the road plus i mean come on it looks so much cooler sitting under the hood

[N2TRUX]

Maybe this will answer some of your questions and minimize the speculation.-

Benefits of Remote Mounting



Ease of installation. STS turbo systems can be installed in about 8 hours with standard tools and average mechanical ability.

Performance Sound. The turbo acts as a muffler and sounds like an aftermarket performance muffler. Turbo spool and rushing air from the blow-off valve make a unique sound that will turn heads!

No need for major modifications to your vehicle. STS systems are designed to "bolt-on" to factory mounts.

Increased gas mileage. Unlike a belt driven supercharger, the turbo utilizes "wasted" energy leaving your tailpipe. Most of our customers get 1-3 mpg increase in gas mileage.

Lower underhood temperatures. No need to worry about melting wires, hoses, or other components.

Converts back to stock in about an hour.

More room under the hood. Future repair work or modifications will not require the expense of removing the turbo system to allow access to engine components.

Cooler oil to the turbo. Cool oil is better for both the turbo and engine.

Approximately 500F lower turbo temperatures. Eliminates the need for a turbo-timer, which allows the engine to run after the car is shut off in order to cool down the turbo and prevent oil and bearing damage.

Denser exhaust gasses drive the turbo turbine wheel more efficiently.

Built-in intercooling. Intake piping provides ~50% intercooler efficiency. There is no need for the expense, pressure drop, and installation problems associated with a front mounted intercooler.

Turbo is exposed to ambient air rather than underhood air. Allows for better cooling of turbo components.

No need for expensive headers, mufflers, or exhaust systems.

Turbo is closer to the tail pipe outlet. Provides a better pressure differential across the turbine wheel which promotes better flow across turbine.

Better weight transfer. Increases traction because the bulk of system is mounted in rear of vehicle rather than up front.

Less noise in the passenger compartment.

[special-K]

Sorry N2TRUX,that sounds like a bunch of sales b.s. to me.A few possible pluses,none to outweight the minuses IMO.

"Better weight transfer?"About like sitting a 12-pack on the passenger floor.
"Increased gas mileage?"They only compare it to a belt system.

Just a sample

[N2TRUX]

It may be sales hype BS, but at least it's coming from someone that knows the system, and not a bunch of " I heard from a friend" speculation. Or "buy all the parts and build it yourself".

I have my concerns over this system too, but it does produce results. On an older car or truck, there isn't as much advantage since space under the hood is not a real concern.

On a late model car or truck where space under the hood is a major issue, this system has huge advantages. Yes, there may be some trade offs but the benefits "appear" to out weigh the trade offs.

I saw the guys on "horsepower TV" do this to a Corvette. Longhorn man is right on when he said that room under the hood is the main reason for this. As for Lag, they said it wasn't that noticeable but the benefit came from cooler boosted air since it had to travel the length of the car to enter the engine. Cooler air is denser air = more good! The car sounded like a jet with twin exhaust turbos screeming...

[russellmarling]

I read a review (In Chevy High Performance Magazine I think) on the STS turbo setup on a 4th gen Camaro. It performed great except in the rain. They said the car ran rough when it was wet because the air filter was so exposed. This would be a major concern on a daily driver. If you plan on driving in heavy rain don't use one.

Great point!!
This is exactley why this board kicks *ss!!!
