Reverse ?

HMUSN · July 10th, 2008, 06:22 PM

So we all know that the supercharged engines need the intake bypass valve so they work in reverse. Otherwise the supercharger would just suck all the air out of the cylinder. So knowing that, how does the turbocharged version work in reverse? The engine is trying to suck air backwards, yet the turbo wants to spin forward so I don't see how it works. Is there some sort of exhausting intake bypass valve on the turbo version? Also, if it does have the valve, does that also mean that it can make boost in reverse? Like how much boost? Like 5 psi or does it go over 20?

Can anyone help me sort this out?
