That crippling HORRID sound coming from your turbo is NOTHING compared to the sound of a BOV.  It's just painful.

I'm not so sure.  I've heard BOV's on other turbo cars and it isn't much louder/different than what my STE sounds like.  My STE for some reason is A LOT louder (probably 3 times as loud if not more) than the coupe.  Maybe its just odd or maybe the turbo's going.  Anyways, if I got a BOV for it and it was any louder than it already is, I wouldn't want to drive it, it would be at the rediculously loud and overexaggerated point IMO..but thats just me.

The TurboXs valves are really loud. My friend has one on his RX7 and another friend has one on his WRX.

The TurboX RFL BOV has gotta be the loudest BOV ive heard.  My buddy with his SRT-4 and that thing will make ya go deaf if ya standing to close to it.

an .mp3 of my 1g DSM BOV:

it isn't that bad is it?  i would think it would be worth it just for the well-being of your turbocharger.

Is the BOV the first or second sound?

I wonder why my bov doesn't sound like that. Maybe because I can't really hear it inside my car with my stereo going, windows open, and almost straight pipe exhaust  :wink: [used to run straight pipes :twisted: ]

it's the 1st sound; the big "PSSSSHHHTTTTT".  i think the second sound was the tires screeching around a turn :)

BTW: that was recorded with my brother holding a condensor mic outside of the car, while my other brother drove by him and let off the gas pedal right next to him.  it was recorded into a Tascam portable DAT.  it was a 1g DSM BOV, but it was on an '89 Dodge Shadow ES with a 2.5 Turbo I 4cyl running 12psi with complete 3" JRB exhaust.  i don't think it would sound any different on a TGP since the BOV vents to atmosphere also.  i know they are pretty quiet on the Eclipse/Talon because those cars are MAF and they vent right back to the intake.  maybe they are quieter with less boost?

ahh... I see... did you get a custom pipe, or just have it welded. My problem is I don't really know anyone who welds well, but I would love to get on put on there.

It came with a weld in adapter, that I had my cousin TIG weld in for me.

I used the OEM pipe, I just drilled the appropriately sized hole with a hole saw, had the adapter welded in, and then repainted the pipe.

Make sure the BOV you get comes with a MILD STEEL weld in adapter.
