From what i hear HKS BOV's have the Whistle sound, and the XS and Greddy have that wooosh sound. Any other name brands that have the whistle sound that any of you know of? The wooosh sound is cool, but the whistle is just awesome. Please post your knowledge

 

I just know of hsk ?

 

HKS SSQ

MAYBE the Greddy Type-S....but I have never personally heard the unit.

 

i hear that the HKS SSQ has idle problems as well as cruise Putts. Is that true or is it caused by a bad install or cause of the MAS?

 

only heard of problems with the HKS SSQV myself.....cept from maybe EvoJimbo

 

Greddy type-s sounds like a whistle. Actually sounds like a pig being squashed!!! hehe!!! goto:www.blowoffvalves.com to listen to a sound clip of the type-s. sounds awesome!!! I have one brand new with evo8 install kit for sale if your interested. Need money for rim purchase

 

how much are you asking for the Greddy Type S BOV? and is all the mounting and installation hardware is included?

 

Turbo xs rfl

 

The reason why your having problems with the HKS SSQV is because it vents to the atmostphere, the only way it will work is if you buy the recirculation kit. The Greddy Type S and the Forge vent back to the intake, therefore there is no idle problems. You get problems with blow off valves that vent to the atmosphere on these cars, it's because of the MAS.

 

yea but is there any way i can get a nice Blow off sound? im looking for one that has a cool sound to it, but i dont want the problems to go along with it

 

well after trying SHKS SSQ the bov sound was nice -i had rpm drop when comes to stop and shifting was ****ty too, I DID buy REC kit, installed- ok a little bit better but still some rpm drop. and it sounds like crap - i tried Forge VTA, sweet bov sound (with yellow spring) even when shifting at normal speeds you could hear, but if you want that BIRD sound - i think i would go with GREDDY TYPE "S" or XS RTFL, i had Greddy type "S" on eclipse T - the sound was nice, i cant imagine with bigger turbo never tried RTFL some people say its the loudest -

 

ok cool, but the Greddy type "S" recirculates right? but you can still hear the whistle loud?

 

feedback please

 

Yes the Greddy Type S recirculates, it is made to be vented back to the intake. I personally like the Greddy Type S, thats what I have on my car right now. I noticed a big difference in sound after I got Cams, well you know why, more power, and i turned up the boost.


I have seen 1 Evo with a HKS SSQV BOV, and his car seem to run fine.


Also, the Turbo XS RFL BOV doesn't have a chirp/bird sound like the Greddy Type S does. It sounds totally different. It is very loud, hence the name RFL (Really F'in Loud)

*Note*
The Turbo XS RFL BOV does not vent back to the intake.
