Engine/Transmission (1998.5 - 2002) Remote mount Turbo

Is this doable? Seem like EGT's would be a lot lower and a set of twins in the bed of the truck with a stack would be easy.

I think that is such a load of crap I don't know where to begin. First, a turbocharger is driven by heat caused by expanding gases, so the most efficient place to put it would be as close to the engine as possible to reduce heat/power/drive force through an exhaust system. Now having a turbo all the way in the back of the vehicle, now you have to run your compressed air all the way back up to the engine. Good senario here, if you take a compressor, turn it on and wait for it to reach 150psi. Now add a 50' hose to that 150psi compressor and measure the pressure at the end of the hose. Loss of pressure over distance would be a major concern with this system, we have enough pressure loss through the intercooler now. And they say its exposed to "ambient air temps" and all the road debris and everything else, i. e. elements. IMHO, I can't believe people actually market that, if they figured it was that good why have'nt major manufaturers been doing this???

Wow, 5 psi of boost and up to 20 with tuning and upgrades !



YAWN

Exactly. Turbine energy is best the closer to the engine it is. The available exhaust energy is the product of pressure AND temperature. When you remote mount the turbo, you lose that thermal element, so you have to have MORE pressure to make up for it.

I can't see how a system like this could even HOPE for 1:1 drive/boost ratios. Drive should be substantially higher than boost because of the loss of heat.

Exactly.

I have seen reporting on the LS1/LT1 (gm gassers) kits... . They do pretty well 5-20 psi on a gas motor is decent... . I think its neat, i wouldnt do it but it is neat. At least they are "thinking out side the box"

 

[Hohn]

Of course, I WOULD like to see one in action, so let my caveat my above post. IF the cooler drive pressure causes better turbine efficiency, the thing COULD work as advertised.

I just can't get over how no OEMs are doing this if it is such a wonderful idea?? You'd think with all the MILLIONS of $$ they have, they would have considered this...

Even max effort turbocharged big blocks in drag racing keep the turbocharger (or turbos) as close to the engine as possible. I can't make sense of running the compressed air charge 15' forward and into the engine, just does'nt make sense. Have you guys seen the electric powered turbochargers on ebay?? They look like an Echo leaf blower, and these people claim big power gains. I look at this product as the same sort of "hype".

Yeah I think it was more of an Fbody thing to begin with... . In a LS1/LT1 car there really is no room for the charger anywhere near the motor and this was probly just a way to get around that with decent power gains with out the major fabrication it would take to mount one near the motor... . I bet the turbo still sees enough heat to make it work decently... .

 

[Tcolesanti]

I would'nt say "it does'nt work" but work efficiently? Thats a whole other subject. I agree with you that most people don't want to spend in upwards of $1000 or more on just a set of headers to bolt on a turbocharger. But, in my mind peicing together a turbocharger setup off ebay and having a custom set of headers built I could probably still spend less than that setup and it would be way more efficient. As for it not being able to fit, hang it out of the hood so it gets a blast of AMBIENT AIR TEMPURATURE!!!!!!! :-laf

 

[SKneeland]

this is a concept developed for the import/tuner market , where space is at a premium. cant see why anyone would bother with a cummins, lag must be atrocious, but on a gasser where you only need a few pounds boost it might not be so bad... .

 

[SEmerson]

They sure must be good. They say 5-20 psi and one guy said he can take bullet bikes. I make 45 psi and am still slow. I also drive a GSXR 1000 and would love to race one of those guys. :-laf

 

[KYLE4]

Those are designed for gassers and for economical reasons You don't have to have a special set of headers made for your car to run turbo there is a guy here locally turbo technology's for gassers and he charges a fortune for his setup's a remote system cheap. Get er done!

Actually, Ricks' systems work quite well... contrary to popular speculation. There are at least 2 STS kitted LS1 F-bodies here in town and they are both in the low 12's or high 11's with an otherwise stock engine. Here, these cars would normally run in the mid 13's.



While the kit is removed from standard concept, and does have some efficiency losses, the cost to benefit very much outweigh doing it the "right way" with the turbo near the engine. If I'm not mistaken, the kit sells for about $4k (about the same as a supercharger for the same car), and will add at least 50% more power than a blower would.



A couple pounds of boost in a gas application is a world of difference.
