Hi I'm ready to be shot down in flames for asking such a stupid question, but here goes. I've not long fitted the HKS BOV and the Blitz sus filter. My question is when I give the car some stick and I'm on turbo should I be getting a whoosing sound, it's not the same as the bov dumping air , but it's there never the less. I always thought an induction roar was more of a well a roar. This sounds like the charge escaping out of the bov. The bov still works correctly when you throttle off, could the bov need adjusting?

Quite normal 4 a turbo engine , the inlet 2 the turbo compressor is at low pressure on boost , so the noise is the sheer volume of air being sucked in2 the turbo. Induction roar will b heard on an atmo engine due 2 the intake air pulse resonance , turbo engines have pressurised intake air so no resonance of any magnitude.

Moby,

I've just done the exact same thing. The majority of the whoosh is that you can now hear the turbo spinning up, cos there's nothing except a stainless sieve to drown the noise.

Can you make your BOV sing different tunes yet?

Not arguing with Evoboy, you understand, 'cos he's the daddy! I always thought a grommet was to stop electrical cabling chaffing through a hole, and Blitz was something my wife did to soup!

HKS have various diffusers (the little three legged star in the outlet) available for the SSQV , so u can change the loudness and frequency of noise , thats nice 4 the sad amongst us , that'll b me then :)
