i want an aftermarket blowoff valve. i dont want a recirculating one. i just want one with real good sound. i am looking at an HKS SSQV and a perrin atmospheric BOV. any comments? suggestions? help would be appreciated.

thanks

what year is your car?

best thing to do is to get a tune. The air is metered just past the air filter and the fuel is preset for that air. when you vent the BOV to the outside you end up with less air than was metered initially. so you end up with an over rich condition. and what tends to happen is that the ECU will adjust and you end up with a lean condition.

so if you have it tuned you will run fine and have the sound you are looking for.

There are a few on here that can help you with the tuning aspect. PM Ralli or Trainable. they both have quite nice setups.

Cheers

I just purchased a GFB (Go Fast Bits) piece and it's very nice. I have the Stealth FX, it's fully adjustable ... from 100% recirc to 100% atmospheric. It allows to to adjust it as far as possible to get maximum noise without backfiring from making the mixture to rich.

If you run 100% atomospheric, you'll run rich, assuming you have a WRX ... I would think the STi is the same, I wouldn't know though.
