BLOW OFF VALVE question
Im looking at getting a set of Blow off valves. My question to all you guys is will say a set of HKS ssqv BOVS using stock turbos affect the performance of my car. Will it give my car a rough idle. I have a 93 TT apexi intake, Brullen stainless steel exhaust, JWT ECU, Stainless Steel downPipes and a RPS SPort Clutch. Also which BOV would you guys recommend. Thanks in Advance

Yes, it's the stock recirc location. It's supposed to be a direct bolt on with the Z32 kit. No, it shouldn't cause a rough idle. Why do you want BOV's? How much boost are you running?

Well i am planning to put a boost controller in soon but im still running stock turbos so at that point anywhere from 12-14 psi. Will the Bov make a difference at that PSI?

As far as quality, HKS super sequential are regarded as the best, RFL's the loudest...

oK the blow off valve goes off when shifting gears and releasing the throttle , right??? Meaning that it blows off the air into the atmosphere, right after you shift, your engine will run rough won't it cause ur computer reads the mass airflow sensor at your intake and correspods with the proper amount of fuel. And the way every ricer does it, they drive hard, shift gears, hears the BOV go off and coasts.. NOT Smart..
WOULDN'T IT BE SMART TO MOVE THE AIRFLOW SENSOR AFTER THE BLOWOFF VALVES THAT WAY YOU CAN BLOW ALL YOU WANT AND YOUR ENGINE WILL ALWAYS RUN THE SAME.

If they are doing their jobs they should be doing the exact opposite.

To answer your question, no. Stick with recircs.

Alrite thanks turtleboy.. i know the intake plumbing but wasn't exactly sure if that would fix that problem or not.

To sum the thread up, stick with recircs, unless they start to leak from age or high boost levels, or malfunction.

the bovs will only release the air pressure to keep from surging the turbos and make that cool sound
theres nothing performance about them
you will need to replace stock recir valves when you get up to rediculous hp because the stock ones cant handle the pressure
