Compressor surge or flutter?

[nfernotalon]

Ok ever since I installed my ebay16g I either get surge or flutter, I tried adjusting the screw in the back of the BOV but it didnt do a thing. It only happens when I shift or let go of the gas.

Any suggestions? Oh i have the HKS SSQV thanks guys

Sounds like normal HKS noises to me they tend to flutter.

Is it a quick SSSHHHHssshhhhSSHhhhSSHHhhh or is it longer and the same amount of time between flutters but just gets progressively quieter? My crushed 1g BOV flutters occasionally at low boost.

Is your wastegate/MBC tapped off your BOV line? If so, that is a major cause for Compressor Surge.

I got rid of my SSQV because of the "flutter" that they're known for. But yes mine sounded like that and was working properly.

Most likely its just flutter, the 16g takes a little longer to hit boost, so youre probably shifting at low boost causing the flutter sound.

Hey guys no my MBC and is hooked up correctly to my jpipe and and to the WGA the BOV is just hooked up to the vacuum line to the intake mani, Im gonna try and see if I can borrow a BOV from someone and try it, my buddys TIAL with a 16g sounds the same too.

HKS SSQV will flutter at low boost. Pretty hopeless... (My HKS just broke and won't open, bad news...(talk about flutter))

Is your turbo ported?

thats just the hks ssqv like everyone else says. that adjustment screw does little to nothing, thus why its actually removed in current versions. more technical details of this can be found by searching "hks" and its the longest thread regarding an hks bov. how much boost are you running?

this is authentic ssqv right?

SSSHHHHssshhhhSSHhhhSSHHhhh .

hmm sounds like you have a boost leak.

but serious note, all of the ssqv's ive heard on many different cars sounded like that, its the way they are designed i guess. i would just use the stock 1g, hell paint it crome and write hks on it in yellow to make it look better.

So I guess its just typical SSQV flutter right? It didnt flutter with my 14b but it does with the 16g, Im running about 19psi and yes it is a genuine HKS, thanks guys.
