Default Anyone here have any experiences with the HKS bypass valve?

I was just curious as to what the sound is like in comparison to the Vortech bypass valve. Does it still have that aircraft like sound when cruising in first and second? Is it louder or quieter? Does it "whoosh" when yo left off the throttle or is it a different sound?

Any valid input would be appreciated.

The vortech is a little annoying at times during highway driving. Does the HKS bpv vent to the atmosphere?

It does vent to the atmosphere. I was just wondering if it also made that aircraft-like noise because I would like that gone. But I think it might just be the nature of the beast. So I hope someone adds their 2 cents that already has it or has used it.

Forget you guys! I bought an HKS Bypass valve and I'll test it out. I'll post my thoughts on it when it comes in.

Cool I'll look forward to your results. I am curious to see how it's going to sound compared to what we have now.

I believe the HKS Race Bypass valves are good up until 18psi.

Well then maybe I won't post up results then! Lol jk. Sad part is that someone on this board must have it but won't post. So I guess I'll be the guinea pig.

I had it on my APS TT kit but never on a SC.

I sometimes alternate between the APS Recirculating BOV and the HKS SSQV Vent to atmosphere BOV. I really can't say which I like better but from a performance stand point I like the APS BOV better since it holds some boost between shifts.

I have one in my garage if you want to test it out until you get yours but I don't know exactly how your going to mount it unless you have a HKS Compatible Flange

Hey thanks for the input man. Unfortunately the HKS SSQV bov and the HKS bpv are different. I wouldnt mind throwing a BOV on but it doesn't vent excess boost when at idle.
