Ok this might be a dumb questions but my wife keeps telling me there is no such thing. I have seen on a couple of the newer cars (Corvette, Hemi Chargers) they are replacing the mufflers at the rear of the car with turbos. Can you do that on a diesel or will there be too much turbo lag. I am not planning on moving mine back there but I just come up with these thoughts alot of the time.

 

There is such a thing, I have seen them and I believe they call them "stealth turbos" or something like that. I would think that it would not make much difference at all how far away the turbo is because 30 pounds is 30 pounds no matter where it is-----maybe I'm wrong, but sounds alright in MY mind.

 

i have seen twins on the backside of a bmw. you would probably loose some heat energy unless you coated the pipes and wrapped them. maybe i should put a stealth turbo on my truck hmmm....

 

its called remote mounting. I have seen it done before and there is really no noticable power loss. I put one on a 99 Land Rover freelander 1.8 when i lived in the middle east. Lets just say i got good at replacing headgaskets.

there is no distance limit from the engine to mount a turbo...in theory, you just have to maintain exhaust gas velocity to the turbine

 

I would think there would be a increase in lag, the turbo now has a much larger volume to fill up to the specified pressure. You also might be surprised how much of an effect friction has on fluids in long runs of pipe, but long is relative I guess (length vs diameter)

 

The important thing in remote mounting a turbo is to not lose any of the energy contained in the exhaust. This would be done through too small diameter of a pipe or a pipe that loses a lot of the heat. You would also need much longer intake piping more than likely.

Putting a turbo on an engine with less than 4 cylinders requires a similar sort of thing with a lot of volume before you reach the turbo. This is because the exhaust pulses do not line up with the intake pulses so you need to put some form of a buffer in there. You can provide this buffer by putting a big air chamber before the turbo and wrapping it in insulation.

 

Like others have said, you can do it but........the lag in the diesel would be a problem. I think the reason it works so well on the gasser kits is because you're not detuning the engine to allow for the performance increase provided by the turbo and the extra fuel. A 400 hp Corvette is still a 400 hp Corvette, until the turbos spool. On our trucks, the hp provided by the turbo is part of the original package. The boost and fuel provided are part of the performance in our base line build. Take the turbo away from our CTD and you would not like what was left.

 

Very good point, what do you say, 110hp?

 

I wouldn't want to guess but I'm sure it would be disappointing.

 

When My last turbo went out I drove the truck a few miles with the manifold only. It had no power and was really loud. It sounded cool though like a tractor.

 

the sts system the turbo is always building boost they just open the BOV. most of these are designed for low boost pressures

 

There are a couple of reasons why you would not do it on a diesel but can get away with it on a gasser.

1 - Lag on spool up due to drive pressure build time. Diesels want bottom end (lag hurts) and the gassers want more top end Lag is not that big a deal)
2 - Heat and flow friction loss on the way to the turbo inlet. May not be too much of a big deal if you want it to cool some due to very high exhaust temps.
3 - Friction losses of the compressed air from the long run.
4 - Lag on bleeding the intake charge on deceleration, on a gaser you block the air flow with the butterfly and then pop a bleed valve, on a diesel you have no butterfly so the air wants to go into the engine so it will really want to over rev when you get off the go pedal and push in the clutch.

 

positive pressure in a gas engine is a totaly different thing... I wanna see a daily driven gasser push 2.5bar !! I have had people say to me... Whada' ya' makin'?? 8 psi? maybe 10?... I say, nahhhh 35... and I get the

 

You can put as far as you want. Will it be effective??
