do you guys know if comptech makes turbocharger for 3.0s? I'd be interested in buying one...hmm....and ive got a question?? whats a "BLOW OFF VALVE"?

 

a Blow Off Valve relieves turbo pressure between shifts, actually technically when u let off the throttle it does it.....so it doesnt suck all of it back in..

 

When the throttle is open, the turbo is happily cramming 15psi (in the case of my WRX) into the intake manifold. When you suddenly let off the throttle (to shift), all that air has to go somewhere, and that's what the BOV is for. Stock ones shoot it back into the intake manifold and aftermarket ones vent it to atmosphere (PSSSSSHHHHHH!!! sound).

If the BOV wasn't there, closing the throttle would cause the air to stop and stall the turbo, causing long term wear.

 

can i install BOV w/o turbo? i LOVE LOVE LOVE the "psshhhh" sound.

 

nah sorry, u have to have a turbo...i heard they made fake ones at one time that hook to your intake.....but u dont wanna be a ricer..
