if the bov leaks air while in boost, will that cause the car to go slower? if i tighten it, should i feel a difference?

 

Yes the car will feel slower because ur losing boost.

 

how do you know if the blow off valve leaks boost?...my hks ss bov makes a shhhhhhhh noise then goes tshhhhh noise... is the shhhhh noise at first boost leaking out? Can i adjust the bov bolt in the back and make it tighter??

you sure the shhh isnt thr turbo?
you know it makes that sound when its boosting.

 

does it make noise while you on the throttle or is it when you let off the throttle?

 

yea i guess it is my turbo....i wasn't sure...it makes the noise on throttle..... i just got confused because my friend with a wrx has the same bov, but when he throttles it i dont hear the shhhhh build up. But when i thorttle it i hear the shhh build up....thanks for the input

 

i now have a wrx, and you cant hear the turbo spool nor the BOV at all as long as the car is stock. people take off this resonator, or "silencer" from the intake of the car, then you start to hear the actualy turbo spool and the BOV goes off, but barely. thats why maybe youre not hearing the wastegate or turbo spool, but on your car, you do. the hks flutters a lot at low boost, partial throttle. hth

 

the shhhshhhh sound that your talking about is probably the compressed air running through your charge pipes.

 

sometimes the BOV comes loose and while at ilde in vacuum the valve sometimes stays open.. the car has to boost in order for the valve to shut which will make you car slower in the lower RPM. you can tighten the screw on the top to keep the valve closed.

 

Thanks camp.. that makes a lot of sense

 

as for the HKS super sequential, supossedly they cannot leak due to their design.
