hello,
I got a question for yall FI folks, since im mostly into na and not familar with FI setups out there. I will attempt to mimic the noises by lettering, so feel free to laugh.

Ive seen a lot of FI cars run at the track and heard various blow-off sounds, but I cant make out what blow-off they ran. All I know of HKS, Blitz, & Tial. Ive heard squeaks, chirps, pssst, "loose sounding" blow-offs, but there was this one AWD DSM at the track...

launched softly and then shifted 2nd gear "squeeench", 3rd gear "squeench",
4th gear "squench" ..thats all I heard everytime it shifted; no exhaust note or anything. It sounded soooo sweeet! compared to any car out there that day including supras. Im sure it was boosting at least 12. It ran around a low 13 @something mph, but thats not the point. Whadda hell kinda blowoff produces that "squench"? Btw, Im pretty sure it wasnt tial, because thats all my friends use and their blow-offs sound "skippy".

 

I think the HKS make those squeeky dying squirrel noises.

 

hks ss - low boost.. (cha cha chaaaaa) mid boost (pusshhhhht) ***** to the wall, 8k rpm shifts as fast as you can... (high pitched squeek)

 

bahahahaha

 

here this will help so we all dont make idiots of ourselves trying to explain PHSSS!

You guys will kill me for saying this...but I call it the butterfly sound. I have the HKS bov.

 

Thank you guys and gal for the replies.. I still cant find the "squench" one.
Actually, its not really squench.. its "squinch" now. I just remembered, since it was under quick shifts.

I found the same "squinch" in this badass Supra video on a night track run. I searched out the mods, and it turns out it had a Greddy Rtype BOV
For those who've probably seen the video, the supra is silver and the opponent broke something on the line ..ring a bell?.

 

Yikes! It says in the description that you must run 15psi to take advantage of the Greddy R-type.
I think its secondary port might be the one causing the "squinch". Probably takes 15psi for the secondary to work.

 

Does the HKS have a whistling sound when spooling?

 

i don't think ya should hear a bov period while spooling up the turbo

 

the HKS ssqBOV is definalty nice if you have the money, but i have the greddy type s bov, and its pretty loud for my taste.
