Got a 2003 sti with a bailey dump valve on it at the moment and was thinking bowt the hks one. Anyone got one or theirs and are they ok? thanks

 

Got one on at the moment, its coming off! Each to there own, but my car hates it! Jerky gear change, lumpy idle............. Im going back to standard re-circ, the best option imo

 

Just put a Turbosmart BOV on mine yesterday - car loves it to be fair - 04 model WRX - turbo is more responsive on quick change, also fully adjustable which helps

 

think they are classed as the best on the market but as said, some scoobys just dont like them , mine included , i had one but went straight back to oem until i have funds for a supersonic turbosmart one

 

I have one and have no problems atall with it, its on a 05 STI, not sure if they work better on certain models, think classic maybe had more trouble with them than the newages (air flow metres different?). I did a search on here before I brought one, and got 90% positive results, glade I did get one in the end.

I found that if the car runs lumpey etc its down to a fitting problem, air getting in where it shouldn't, make sure all clips are tight and the gasket which is already on is in good condition, so other than that I can see no problems.

 

SSQV is a very well made unit. Has a re-circ option too.

 

Had an HKS ssqv on my STi2, car always ran perfectly with it on and I'd certainly recommend it

 

Had one on my last scoob, 2003 sti type uk ppp and had no problems at all, it gave a nice loud whoooosh.
