1g BOV flutterbox
doesn't matter what psi i get my bov flutters so bad. it actually doesn't sound bad, but isn't it suppose to make a solid whooosh sound?? vac source off intake manifold for bov and wg aswell. both go directly into the intake manifold.
could the bov be bad?? |
Re:1g BOV flutterbox
Are you sure the bov is opening? It could also be compressor surge. try a stronger vacuum source.

Re:1g BOV flutterbox
My 1g has a very strong whoosh. I think yours is not opening. Can push it open with your finger? Mine was cruded up but I cleaned it and its good as new.

Re:1g BOV flutterbox
my 1st gen dsm bov does the same thing and my vac lines are just like urs, i think im going to use the nipple on the turbo for the wg and give the bov its own vac.

Re:1g BOV flutterbox
Maybe you have oil in it... When i blew my motor...my blow off valve was making a weird noise at idle, and would lag and stutter when i let the throttle off... then when i took the lines apart there was oil in them... thats what was causeing it... like when you have air in your brake lines... they tend to stutter when you stomp on them

Re:1g BOV flutterbox
My 1g DSM BOV goes "Choo" when I let off the gas, not whoosh. I also get fluttering EVERYTIME... i think its compressor surge. :(

Re:1g BOV flutterbox
pop the hood with the car idling, pull the throttle cable and give her a nice rev. Feel if any air comes out the bov. If not, it's either not hooked up right, or is bad.

Re:1g BOV flutterbox
get one of those vaccume pumps at pepboys put it on the vaccume port of the bov... it should open between 15-20 inches of HG.

Re:1g BOV flutterbox
check your vac. source. mine did that to when my vac line was pinched. use a different vac. line.

Re:1g BOV flutterbox
and the answer is:
compressor surge. do to the fact that it is crushed. the bov will not open under low boost AT ALL!!the only time i got it to open was when i boosted up to 8lbs. so i put an uncrushed 1g in there and it's loud as hell and sounds exactly like a HKS SSQV/Greddy Type S. so i'm happy. |
Re:1g BOV flutterbox
your 1g dsm bov is crushed? no wonder it wont open!! :-[ you need like 20+ psi to open those things LOL, glad you got it fixed...compressor surge...bad!!! :-X

Re:1g BOV flutterbox
i recomend T ing off one of the large intake manifold hoses, PCV valve, charcoal canister hose ex. get a 1/4" plastic T at the auto parts and the small clamps for the hoses and T off the charcoal canister filter for the wastegate and the PCV valve hose for the BOV, both of these are strong vacuume/boost sources.
