lol satanic, i was actually quite surprised when people said flutter is caused by the BOV. :P

I myself use the HKS ssqv. I do get a soft flutter sometimes if i release my throttle at low revs but once i rev it higher than about 2300rpm? I get the loud noise from my ssqv.

Those who wants real flutter, try taking out your BOV or plumb it back. It'll sound like a VL Commo in no time!

plumback bov so you dont get bov noise... and mount the bov parralel to the throttlebody so as the air bounces off the TB back down the piping it will be in direct line of the bov

ie... if you are using standard elbow for rb20/25

why is this still going? my post was short sharp and too the point...

compressed air has no where to go when the throttlebody is shut (car 101 - throttlebody closes when you take your foot off the accel pedal)

it bounces back down your cooler piping to your turbo and comes out your pod... if you have an airbox you would still have flutter - you just cant hear it

by having no bov, a bov not mounted correctly, a pod/no filter at all or an aftermarket bov which is not plumbed back and not in the right location - you will have flutter

to fix this... mount bov directly inline with the throttlebody and plumb it back into the cooler piping before the turbo

END OF DISCUSSION :P

i had the same bov and at 1st the spring was too tight making it flutter a little bit coz air would be goin back thru the intake, losened the spring a bit and it was fine, also to not i had the stock bov andit fluttered an was plumbed back into the intake only at low revs though, so i dont think that makes a difference...

As far as I am concerned it is your wastegate???

LOL ok, learn how a wastegate works then think about ur answer...

      That looks good, but I think you're going to need much beefier side skirts now.

      new 1.5 LSD issues/concerns

      By GTSBoy · Posted

      I gotta pull you up on this. It's driving me crazy. A shutter is something that closes, like over a window or in a cmera. The word you want is shudder. That LSD is clearly f**ked. Take it to a diff shop and get it disassembled and examined by an expert. YOu might have plates welded together or something equally crazy.

      S1 rb25/s14 starting problem

      By GTSBoy · Posted

      Check the Nistune doco. There are a few assumptions being made here that might not be valid. I will list the things that occur to me: Base map. Base map for what? Base map for Z32? Then the cranking pulse width is probably wrong for an RB25. The extra 500cc of capacity might well be enough to prevent it from catching. Base map for RB25? I don't think you can load one of those into a Z32. You have to just make the settings correct for an RB25 in the Z32 base map. That is either K or the TIM to get the pulsewidth right. Loom. You bought a loom for an RB. And you plugged it into a Z32 ECU. Did you make sure that any iwre differences were swapped. From memory, there's at least a couple. And as per the others, I would suggest making sure that the fuel pressure is correct while cranking and that the injectors are actually flowing as expected. They really must come out and go on the bench, unless you do find that you have messed up as per above points. I would also suggest watching in Nistune to make sure that everything is reading correctly. That the correct binary flags are raised at the right time (like the crank signal), that there's no stupid values in K or TIM. That you have not got mismatched firmware for the ECU and/or a wrong image loaded.
