your intercooler doesn't cool your turbo....
So exhaust back pressure does not overheat a turbo, it's only hight boost that heats it up because it will spin faster.Tenacious-B said:If I were you I'd do more research on these points. You are confusing a few things and I think that is what is leading to your concern.
To answer your question though, having a more restrictive exhaust won't cause your turbo to excessivly overheat. In overly simplified terms if the exhaust isn't as free flowing, then the turbo won't spool as quickly. The higher the RPM's on turbo, the hotter it will get, so if it's not spinning like crazy you won't have the issue of it overheating.
I meant a restrictive exhaust with the turbo boosted to 15psi or more.White91GSX said:if your engine is over heating you would notice it on your temp gauge inside of your car... and no restrictive exhaust wont cuz exxesive(sp?) overheating or every stock turbo car would always be over heating
When you are pushing the 1600 degree mark what is your stock temperature gauge reading?knewblewkorvett said:Huh?
My EGT tells me exactly what the temperature is coming out of the engine via the manifold. When I'm beating the crap out of her (ie. doing a steady 125 mph (on a closed road ) ), she will get up to 1600 degrees
At a steady 65 or so it is no where near that hot. Is the air/fuel different at a different steady speeds, hell, I don't know. All I know is I do not want to go over 1600 degrees and that is what the EGT tells me.
