im sure someone has posted this before, i already tried searching through previous threads, but can someone please help me out and point me in the right direction as to what kind of blow off valve is good for the msp? also do i need both the bpv and bov?
 
If you do not want to stall you should keep your stock bpv. As for bov any one will be fine for the msp. I personally like the HKS SSQV or the Greddy Type S.
 
i have a Greddy type-s and i do stall rarely but I can tell my car wants to stall.

what is bvp? Which BOV has the loudest sound =)
i think you mean bpv(by-pass valve). its a valve meant for recirculating.
the loudest bov out there would have to be the turboxs rfl.
 
If you dont want to stall and not use the BPV/BOV setup 505zoom posted then get the Forge Motorsport 2 piston BOV. It works with stock piping and replaces the BPV. It vents without stalling becasue of the 2 piston design. It sounds like the turkey with a woosh of air (not as loud as Greddy or TurboXS). So gooble goooble goooble wooosh!

If you want to run any other BOV you'll probally have to use the stock BPV with it. I recommend the HKS SSQV...cuz its not air sounding like 99.9% of BOV out there. Its not gonna leak under high boost (not does that matter). But the main catch is that HKS SSQV has a recirulating kit. so it it doesnt work you can spen a extra $10 and recirculate it back like the stock BPV. Greddy is my second favorite....its pretty loud. If you want super loud then its TurboXS RFL BOV. You can guess why its called "RFL." It doesnt really matter to me...just that it works. you can checkout clips at www.blowoofvalve.com

As soon as forge releases the Forge BOV...I'll try to put on HKS SSQV when I get hard pipes. So hopefully you'll hear: Gooble Gooble Gooble Whoosh Psettttt...(three sounds) pure ricer s***!
 
If you want little to no stalling with stock piping get the Forge BOV, actually it's known as a dump valve on their site. Kit was 170, although I got one before the actual production run, so it may be cheaper. It only stalled a couple of times the first day or so, and that was from 4k or higher to idle drops. Now even in the same situations it will dip down real low but it hasn't stalled out completely in a while. Makes a nice super turkey then whoosh sound, and I'm at stock boost no intake. Can't wait to hear what it sounds like with more boost and the intake/dp/exhaust.

You can recirculate a Greddy Type S too. All you need is the 19mm adaptor (which costs about $12) and some 19mm hose. Then connect the adaptor to the 19mm inlet hole on your stock intake (where stock BPV blows air into).

Tightening the Spring Tensioner on the Greddy type S will also help alliviate stalls, but it will not iliminate them (at least not in my case) I've had mine in for about 2-3 weeks and have stalled maybe twice. Both times were from dropping the car into neutral when it was over 2000 RPMs. Any time I drop it below 2000 RPMs it will only bounce the RPM meter, but not stall.
 
Do we have to talk about this every week?

I have stated repeatedly that under normal driving my car DOES not stall.
When I bring it down from high RPM, i tap the throttle once or twice to catch the revs.

If you have a vented BOV on almost any new turbo car, you run into the stall. Its not an MSP specific issue.
 
This is a question I have had for a while and never saw a post that clarified it. I totally understand the whole new BOV recirculated into stock Bpv to prevent stalling and kill the turkey if I remember the DIY thread.

I've always wondered if adding the old Bpv into the loop would "hurt" the system. I mean you are buying a new BOV valvue cause it is better at handling high boost and it just plain operates better, lenghtens turbo life blah blah blah. But wouldn't running the charge thru the old Bpv again just take away some of the advantages? Wouls there be a little more hesitation since the air had to go through another checkpoint before getting into the engine?

Please clear up my confusion. Maybe I dont fully understand how they work, thx.
