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?

unmm......... ok........ are you trying to tell me the belt runs the opposite direction when car is in reverse?

 

OHHHHHHHH.... yer being sarcastic...

lol

 

It doesn't?



The guy didnt respond back at all, im sure he felt like a complete dumb ***.

 

Well here is how it works with a turbo.

when going in reverse the turbo DOES suck the air out of the intake, and pushes it back through the exhaust where it makes its way into the cyliners.

 

exactly, I lol'd when i read the original thread.

 

That Cobalt guy should just redeem himself on the internet by doing his own port and polish job to show everyone he's not a complete dumbass, all he needs is a bag of sand. Probably want to remind him to put it in forward rather than reverse, no need to polish the bottom of the valves.
