need help with blow off valve

[nickoli240sx]

i just got a bov from my boy i put it on my ka24de-t and when i build boost and come to a stop or wen i push the clutch down and let the rpm fall it cuts off but with my old bov it doesnt do that,is the bov bad or wat should i try cuz its sounds better then my old one

It cuts off? I'm not sure what you're talking about but sounds like you are venting the BoV to atmosphere and its causing the car to stall. Recirculating the BoV would help.

idle drops down to 0 when i build boost but my old bov doesnt do it

Sense: this makes none.

How is your car making boost if it's at zero rpm?
Are you trying to say it stalls when you give it gas?
Explain, using words, what is happening.
Provide details such as:
-what kind was your previous bov
-what kind did "your boy" give you
-was anything else changed/modified at the same time
-did the problem begin right when you swapped in the new bov

ok i have a cheap bov that runs good but is not lound and my boy gave me a greddy bov. i build 10 pounds of boost push the clutch in and wen the rpm goes to 0 it cuts off but i can keep it on if i give gas but only happens with the greddy one

Hahaha I was gonna add the "your boy" also! I agree this dude makes no sense.

Sounds like its venting to atmosphere a d causing the car to run super rich since its missing the metered air and causing it to stall (0 RPM). Venting the BoV back into the intake after the MAF before turbo would help.

So you're saying the car stalls unless you give it gas to keep it running? A Greddy bov is adjustable. Most likely, you need to tighten the spring so that it doesn't stall your engine out.

i tryed that as well

You need to adjust the bov! I had the same thing with several cars. I would adjust the bov to a loose setting so that it would sound louder, but they would all stall when coming to a stop. That was years ago thou! I know have mine to a tighter setting so that it won't stall. I had to keep playing with mine over, and over until I got it where it won't stall.
Good luck!
