Help On B.o.v Style And Sound

[O.I.C Napster]

Hey guys, i just brought me a R33 Gts-t and was wanting a bov for it. I dont want the one that just goes woooosh (haha) im wanting the one that kinda sound like it has several woooosh's (sorry cant put sound effects on lol)

I think its called a super sequencial?

Your help would be greatly appreciated.

Thanks

Matt

PS a photo of what it looks like would be great too.

take the bov off and you will get flutter. It sounds good

isnt that the cheap way? im sure there is a BOV that does the flutter sound?

mine does the fluttering sound and the wooosh sound.. it depends on how u release the accelarator.. if u spool up ur turbo and build up heaps of pressure in the intake pipes, and u release the accelarator quickly, it makes the wooosh sound, if you release it slowly it makes the fluttering sound.. i think this also has to do with what type of intercooler you have (large FMIC or SMIC)..

you're talking about the HKS Super Sequential Blow Off Valve (SSQV)

it flutters/chirps/whistles agressively , when you let off the throttle....but if you rip on your engine and boost up HARD and let off the throttle, it makes a piercing woosh as it dumps off excess pressure and does it's job to prevent compressor surge (which will also make a fluttering sound)

the HKS SSQV makes two different sounds is because it has 2 valves instead of most bov's single. the small one (purple colour) only vents at low-moderate boost.

so if i dont want the flutter or the woooosh sound but like a higher pitch whistle like steam out of a kettle but real short, oh and have it 50/50 plumb back for the fully sick kettle sound ? what would i buy ?
