So, what the hell does a screamer pipe do that is any different to a wastegate or BOV? I am obviously missing something here.
Sounds to me just a very efficient way to get tugged  |
a waste gate and bov serve completely different purposes, the waistgate stops the turbo from delivering to much boost, the bov or recirc valve let off presure on throttle shut situation, to stop the back pressure in the inlet damaging the tirbine in the turbo, as for screamer pipe I'v got no idea what the advantage of one of them would be
