Talk with Huff on the other site. He is the turbo expert around these parts.
I may be wrong about this, but my gut feeling is you can't feed a turbo into a supercharger, unless you have a clutch on the supercharger that will let it freewheel.
detroit diesels were made this way--8vt92--turbo and supercharger both--supercharger for down low--turbo as the r's came up---theyd hummm!!!!!!!!!I may be wrong about this, but my gut feeling is you can't feed a turbo into a supercharger, unless you have a clutch on the supercharger that will let it freewheel.
See that is what is confusing me. Why when you triple the rpms with a blower does the boost go up more. That to me makes no sense. Why wouldnt it be linear, its running off the crank, so as rpm's go up the blower speed goes up. Why would it push more air up top (more efficiency maybe ) that what it should.
And I would say your EGT thinking is false. I can see it easily with my truck. If I lug it with no boost (say 1300rpm's in 4th gear), I'll be roaling the coal and my EGT's will go up to 1000*. Now take for instance me going down the road, say 2000rpm's 3psi of boost and 600* EGT's, if I step on it it will take me almost triple the time to get to 1000* compared to lugging it, and this is with hardly any smoke output (because I would be at almost 8psi boost).
