Can anyone tell me how long the adjuster screw is on their blitz BOV's asmine sound like an owl only at high boost, no response an lower end and my thinking is they need set up.

 

Cheers John

i just fitted blitz bovs today,and the sound is only on high boost ,nothing on low boost....

Ive fitted blitz units on hard pipes this week, normal driving you barely hear them but when i give it some they go quite loud. As long as the car idles fine they shouldnt need setting up. Hope this helps. Rob

Thanks for the replies guys.

 

When I fitted the valves only when I really pushed the car was there any sound from the valves. I have adjusted the screws on both in and now I can hear the valves exhaust when under load but not as high as before. As a matter of intrest what length of the adjuster is left on your valves so I can compare. I have no issues with stauling etc after fitting them.

John have you blanked off the recircs?

I havent done anything with the recircs other than remove the pipe from the manifold and use that for the new fit valves. I have seen posts that does mention blanking them but I thought I would get away with leaving them on. Guess I need to blank them then.
