please don't hate me

what is the difference between a blow off valve and a wastegate? or is there, thanx

i could be wrong, and i probably am, but i think the blow off valve just releases the air going from the intake to the manifold, and the wastegate actuator is this "flapper" that controls how much boost you use on turbo...because you get boost from the exhaust spinning the turbine wheel.....so like i said dont quote me on this because i am probably wrong.

One other thing, you shouldnt be sorry or think were gonna hate you. Its a legit question.

Search for the answer next time...

Yes, Metalhedskater is pretty much on the money. BOV releases compressed air when your throttle closes so you dont put stress on the turbo.

Wastegate regulates how much boost/psi the turbo builds. It allows exhaust gases by the turbine wheel when the turbo has reached a certain PSI so the turbo doesnt keep building boost.

so a boost controller controllers when the wastegate opens?

Exactly.

If you go to www.racingknowledge.org, DSM section, there is a sticky where I explain all that stuff in some detail. If I wasnt so lazy I would transfer all those good threads to this site, so I could stop linking or point to RKO :) Someday...

www.howthingswork.com is also a good site for technical info like that
