Default Post-engine "supercharger"

Just throwing this out there....

I was talking to my buddy from the TCCoA and we were playing with the idea of a supercharger in the exhaust. Ya know, something to create large amounts of vacuum to get air through the engine and out the tailpipe faster. So instead of pushing large volumes of air into the intake, you're pulling large volumes of air out the other side. I suppose it would have to be electric, so maybe it'* a pipe dream. But I figure with the right valve overlap, maybe it could work. Thoughts?

Hmm not too sure on this one. Although I tend to think that it would be detrimental to performance. If people wanted as much flow as possible we would all be running ridiculous 6" exhaust or something.

I think the key is balancing intake and exhaust, so neither of the 2 is out-flowed.

I think that would be interesting, and maybe would show some real gain...Problem is that the engines rely on the a proper amount of back pressure to make their power.

I don't see it as something very practical. But that'* some very creative thinking!

Sort of like a "bizzaro" turbo setup in a way

Thing is, would this "inverse turbo" setup get you more gain than an actual, normal turbo setup? If not, the point is kinda moot.

there is a turbo setup that is mounted where the muffler should be on a F body, then there is a pipe up to the intake, it looks really weird but keeps the air cool and there is no need for a intercooler

one of my friends is running one on a 2000 SS that is HEAVILY modified that is pushing 600+ hp on 6 psi
