4agze + bov (read before flaming please)

[Intense]

I've noticed with my car that sometimes even after you've let off the throttle it continues to rev, it's nothing huge but it's noticeable especially at slow speeds. Would a blow off valve alleviate this problem? And would it be possible to get a plumb back blow off valve that plumbs before the supercharger. And just so you guys can flame me how do I get the woosh noise and sick fluddars bro hahaha

could be lean AFR's that are causing it to continue revving....but if you really wanted to, you could always add a bov....flutter is caused by the backpressure building up in front of the turbo causing air to travel bak out the air filter (thats how i understand it, correct me if iam wrong)...so the only way to get a flutter with a supercharger would be to make the rpms of the supercharger drop as quickly as possible so backpressure can build..

then again...i aint no supercharger xpert.....so i aint sure how accurate my advice actually is!

but i hope it helps ya out a bit!

if the throttle is before the SC.. then you have that amount of volume to keep engine revving when the pedal goes up...
a BOV uses a vacuum signal to operate.. maybe you could take that from between the TB and the SC?

is the throttle pre or post supercharger on them? i probly should know but the only time i ever look is when removing the S/C and adding a tubo to them which involves ditching everything on the intake side of the engine.
if its throttle then S/C there could be a small vac leak, if its S/C then throttle it could be the blade on the throttle not shutting as quick as it should, do they run a small vac operated stopper on the throttle? could be adjusted incorrectly or the accelerator cable could be gummed up?

lotsa variables

The throttle body is before the SC. I'd agree with Linden, check for vacuum leaks.

If you really want to go for a BOV, check out my epic when I installed one..
