you mean the TobayFest2 vid that's 65mb long?jdmuscle said:hey man.....may be u could hear it in the tobay/obi cruise video.....i have the type ii in my t78 supra...sounds very nice...i love it!!!![]()
awesome! thank you so much for posting these and make sure to post the Type IImav7 said: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.

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.

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.mav7 said: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.

Great Post Mav! Now if someone can chime in on my question, lolmav7 said: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

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.SupraFan55 said:Great Post Mav! Now if someone can chime in on my question, lol

Best combo, 1 hks racing type 2 and 1 hks ssqbov![]()
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)mav7 said:I'm almost willing to bet a SSQBOV... after the burnout there is a really high pitch to the blow off sound = ssqbov.

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.upyun said: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
