Now, I don't know much about turbocharged cars or turbochargers in general.. But I was thinking the other day..

What is the point of a blow off valve? Wouldn't you want the air to stay in the turbo, so it doesn't have to spool up again when you shift?

But then, I suppose, what happens when you're not shifting but rather taking your foot off the gas to slow down.. I guess I just answered my own question?

Oh well.. maybe someone can explain it to me in detail.
