Epic FAIL

We all know that forums can be a rough place from time to time and even the most sensible of questions can be met with an unprovoked flaming from regular site trolls.

So, when you are a complete noob it does tend to help if your question is factually correct. But sometimes even the most senior of forum members can become misinformed about the workings of a car engine. Forums are minefields mixed with fact, fiction and people’s opinions of what they think is best, a bit like Wikipedia.

I really can’t think of anything to write that will prepare you for the thread I found on Cobaltss.net, so I’ll just paste in the original below and let you decide…

Although If you think you can answer his question, feel free to have a go…

“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?”
