"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?"

BUT! Just ito be sure I'm going outside and have wife watch my engine as I back out of the driveway and see just exactly what the engine does with turbos when going in reverse! I'll post if anything monumental happens.

No really, he might be on something, we've never seen what happens with the engine with a closed hood, maybe its like what goes on behind closed doors.

Note, if I've gotten any facts wrong in the above, just ignore any points I made with them
