Forge Bypass Valve Owners!!!

[AutoXRacer]

What are the benefits of upgrading to the Forge Bypass Valve?
What differences are there to the stock piece...?
Will it help produce more power, etc...??
How do you like it?
Any long term problems/issues...?

Thanks!!(thumb)

Good questions.

I'm thinking about getting the Forge BPV as well.

I wonder if PG has them in stock? I just might get me one....

Forge BPV folks, please offer your opinions!!

Just spoke with someone at BEGi about this valve; thats where I first saw it.
According to BEGi, the valve holds boost better than the stock valve. I asked her is you had someone drive the car with both valves would they notice a difference...she said no, other than the Forge sounds different...

So whats the point of changing this part...? She did mention it was a better quality part than the stock valve, but the stock valve wasn't a bad piece either...

(uhm)

you replace it if

A)you like the sound
B)you are going to start upping the boost on the engine via engine management or manual/electronic boost controllers.

If you start pumping way more boost in, the stock bpv might leak.

 

[subparpunk03]

oh yeah also, 99% of people replace it JUST for the sound.

I just took my HKS off and put the stocker back on. I can tell you that shifting is a little smoother with the stocker on. Although once I get my PNP connectors for my CP-E EMS, I am thinking of buy the forge bpv and selling my HKS.

There is no reason to change BPV or BOV's unless you start producing more boost than the stocker can handle...which is a level most people wont get to...However, if you want to waste hundreds of dollars because you like the sound quality better, well that is your perrogative...but i think it is lame

Does NOTHING for performance and running a BOV when your car was designed to run a BPV is even dumber.

Thanks for the comments... I was particularly looking at the direct replacement for the stock BPV that Forge offers...its identical to the stock piece...

Doesn't seem like its an upgrade I am interested in doing...

I had read some where in this forum that some members have experienced better throttle response, quicker spool, and slightly higher boost levels +1 +2 psi...supposedly the boost is steadier...

Anyone can confirm this...?
Again, this is strictly for the Forge BPV (the direct stock replacement)...

An upgraded BPV is not going to affect spool or throttle response and is certainly not going to raise boost levels. Anyone who claims that a BPV decreased spool time, increased throttle response, or raised boost is flat out lying. And if they believe it to be true they better post some kind of proof.

...unless the stock BPV is leaking boost, which they have been known to do...

This is a direct qoute from PG:

"You’ll notice improved throttle response, better boost handling capacity and quicker spool recovery. Machined from Billet aluminum the MSP02 is completely tunable and serviceable to keep up with your modifications as they progress.

Installation is simple and takes less than 10 minutes requiring no modification to the factory plumbing. The BPV comes with Forge’s “No Hassle” limited warrantee and is available in polished or black anodized finishes."

Anything else Crash???

Come on dude, of course the manufacturer's quote is going to say some crap like that...I call BS..proof doesnt come in the form of the manufacturer's quote when trying to sell the million of them they produced

I'm all for the performance value. If upping the boost is where this thing helps the most, then I'll just hold off until I actually need more boost. I want to get my car ready for tracking events in the distant future. So I'll save the extra 150 or so for the wheel and tire package. Thanks for the info you all. Until then, I'll just continue to use the stocker until I actually need to go with an after market BPV.

don't knock it unless you try it! i can speak from experience that my stock BPV DID leak especially on the spike which can be confused with throttle responce so it is what it is you think what you think and i know what i know. i do have the forge and i stand by it and in case anyone was wondering i am running the blue spring with no shims

Different car but the same principals apply. Stock car brought to the same temperature with the only change being swapping the factory valve for one of ours:

You really need to inspect your forge for leaks. I was able to move mine about a 1/4 inch and im not sure it its still leaking or not. Beautiful valve but the quality control is less than impressive on these unit.

 

[astraelraen]

I replaced my intake on the CX-7 before I had my forge bpv and you can definately hear some sort of noise which sounds like boost leak to me with the stock valve. Once I put on the Forge a few days later the noise went away.

We had a batch go out with two problems: loose lock-ring (this part holds the flange to the valve body), and lack of thread sealant on the 28mm side port.

Apologies for that, I've made the techs in the UK aware of it.

If you buy one now, how will you know if its part of the bad batch...?
Are there serial numbers that we can look for?

Nothing like that. It wasn't even a complete batch that had the problems, just a smattering of valves.

The best thing to do is ask for the valve to be inspected when you order... if you order from one of our dealers just ask them to verify that the side port and the lock ring are tight. The valve should NOT rotate on the flange. If it does it is too loose.
