A Furious niggle at the back of my mind.

This thread may have something to do with the "skittle?" thread, but in "The Fast And The Furious", when Brian Spillner (aka Paul Walker) is revving up his green Mitsubishi Eclipse at the stadium (just after the first truck hijacking), what is the weird noise that the engine makes as it revs back down? It's a sort of cross between humming and buzzing... hard to put my finger on, but is really obvious. Look at the 2nd chapter on the DVD.

its the blow off valve, re;eases boost pressure as you come off the throtte to prevent it from surging back into the compressor after you close the throttle butterfly

wastegate is 1, blow-off valve is other.

the wastegate comes before the turbo which releases gasses so the turbo doesn't spin more than what its set to(at the wastegate).
the blow-off valve, as megotmea7 said, takes out the pressure that is made at the intake after releassing the accelerator(the throttle body closes) so all the air doesn't go back to the turbo and damage it.

Buy the turbo , and intercooler , and then go for the waste gate and blow off valve. That will give you something to be happy about!

id but the turbo and wastegate first. without the wastegate you'll have no way to regulate you boost... and you'll have a broken motor

Errr, film editing error, because his car has a 5 or 6 speed gearbox. Or just the same shot viewed from diferent angles.

well in the second movie, in the first race, brian walker changes up 18 times, and always has that little bit more room to push the accelorator that little bit further.
