SSQL Screw ???

[tang0]

lo all ...

bought a hks super squential bov a while ago, 1nd hand, and just got around to fitting it, great noise, apart from the whistle thing, that just gets annoying after a while ...

anyway, question is the screw adjustment on the back ... what teh fook does it do ??? tried adjusting it in and out, couldnt really notice much difference other than it stalled a bit on the full out position ...

anyone got any clues ??

cheers

could be like the adjustment screw on the blitz dual drive that I had on my S15. Adjusts the spring resistance for the valve. I had mine fairly full out and would stall on clutch engagements when stopping at lights or even driving along without blipping the loud pedal.

The benefit is getting the pssst on gear changes even when not boosting If you adjust it inwards bit by bit and test it, you will get to a point where it will not stall, and will be able to vent to not hold revs up and not cause de-spooling of the compressure wheel on throttle lift off. If you adjust it all the way in it may not vent quick enough, and cause the compressor to slow, then has to spool up again on gassing it
