ke382TG Forums Junkie Registered: May 2002	Re: Blow Off Valves Thu, 21 October 2004 04:17 I have had two types of BOV mounted in 3 different ways 1st was the classic Bosch BOV plumbed back, it was almost silent in operation. 2nd was the same Bosch BOV venting to atmosphere, it let out what I would consider a low to medium level classic pssshhhhh sound. It wasn't too loud but the sound was there and could be heard outside the car, this worked very well. 3rd and current BOV is a GFB one that works fine but is considerably louder than the the Bosch one was. The sound doesn't bother me as I don't do laps and look like a tool . As far as I am aware the only type of BOV that are distinctly different sounding are the super sequential type (HKS) (I like this style as it sounds like a WRC cars BOV). Most just make the classic psshhh noise to varying degrees. The "flutter" noise that some peoples cars have is NOT a BOV noise (despite what some think), it is compressor surge due to not having a BOV or having too much spring tension in the BOV so it is not even opening or is opening late. The people who want the "mad" flutter noise created by compressor surge should get that "mad" pinging noise that some finely tuned machines have as well they both do wonders for your car. Good luck with it mate, must be hard when you can't just head down to your local car hang out place and find a car with a BOV you like the sound of and just ask them what they are using. Cheers.
