I've been told my single HKS SSQBOV sounds like a Racing Type 2.. so you can listen to it here: http://mavbsd.rh.rit.edu/supra/ssqbov.wav

The HKS SSQBOV on a single turbo sounds nothing like it used to on stock twins.
This is what it sounded like on stock twins: http://mavbsd.rh.rit.edu/supra/video/bov.wmv

I have a Racing Type 2 BOV sitting in the garage I am going to throw on, I'll be sure to post clips of the differences between the two.

awesome! thank you so much for posting these and make sure to post the Type II

your SSQBOV is exactly the sound i was looking for in a Type II :)

No problem, glad I could help. BTW the boost on the first video was probably 25psi or so. The sound does get a bit different on lower boost levels... I have a video of that too but it's a longer download.

its pretty interesting that you say that since I came to the same conclusions even on my twin turbo setup on my 3000GT. I have upgraded turbos and the BOV sound is totally different at 10 psi and at 25psi. I have a single HKS SSQBV.

I'm almost willing to bet a SSQBOV... after the burnout there is a really high pitch to the blow off sound = ssqbov. When doing burnouts and anything that doesn't build much boost the ssqbov makes a higher pitched noise. The Racing type 2 will "shutter" and have a much lower pitched sound.

Best combo, 1 hks racing type 2 and 1 hks ssqbov :)

Thanks for the quick reply!:) How bout that rephrased :), Best Combo: 2 SSQV's(or 1) mounted on FMIC Piping, thats what Adrock has and I wouldn't be suprised if it is the same setup on the T51R Supra. Thx again for the clips and vid Mav!

i've heard that the one Type II and one SSQBOV will create blow off at different times which will stress the turbo (like compressor surge)

i also heard that the "shuttering" effect is just as bad as compressor surge since a blow off valve should "blow off" all the excess air in one powerful exhale, not "shuttering out" bit by bit. i've been told that the "Shuttering" noise is actually just a misadjusted BOV

I have to agree with you. But most Racing II BOV's from HKS sound like that (at least from what I have heard)... And I have never heard my ssqbov do it.
