Vent to atmosphere for $6!!!

[yellerandahalf]

Hey guys, i tried the "Trick BOV fix" here
http://www.msprotege.com/vbb230/sho...ov&pagenumber=2
with a few changes. Instead of using the 1" brady valve and gluing/siliconing it on there, I used the 3/4" one-way valve and used a drill to get the threads out of there so I could cram the hose in. AND IT WORKED!!!!!!!!! It drives exactly like it's recirculating, no stalls, not even a dip in the revs dumping from redline, high load. Amazing. A few observations were made, however. It is not incredibly loud, about 3/4 as loud as with it not on there, most likely do to the passageway in the one-way valve is so friggin tiny. Also, I've got one hell of a turkey under there. I did not hear the turkey at all when running simple open atmosphere with the stock BOV, but with the one way on there, it's mean! Interesting, huh? So I have an idea. The valve is a 3/4" diam w/ NPT threads. I think I can rig up some sort of adapter to allow me to use, say, the 1.5" or 1 3/4"! Woohoo! They have more flow than the BPV, so it should greatly inprove the sound. The hole in the 3/4" one is only about 3/8" in diameter! I highly encourage all of you to try this out, heck it's only $6 at Lowes!! PM me if you need more info on where to find it. I'll post up when i make the adapter.

link at that thread doesnt work either

link to the thread works but spooled's valve link is down. shouldn't take much brains to figure out what kinda plug & one way valve to get, though.

[Spooled]

Sorry guys. I had deleted the pics and forgot about the post. I happen to have the valve here at work and will take a pic.

if your getting crazy turkey take it off. Thats compressor surge. Most people get a bov to fix the surge!

That's the link to the pics. For the record, though, I installed it again last night and my car wanted to stall bad at some points. It also would bog when getting on the gas. I think that the BPV leaks under low boost. I am going to look into getting an aftermarket BPV and see if that leans it out a little, too. It may be one of the reasons that the MSP runs too ruch from the factory (leaky BPV). We'll see...

ANy idea of what that may be called?

[t3ase]

Also, the intake side of the BPV hose is a "D" shape. Was there a plug that fir that or did you have to use your imagination for that?

[Spooled]

Not sure what it's called, but I found it in the plumbing section at Lowe's. It's a 3/4" one-way valve and is spring loaded. The sticker says P32S 3/4".

I'm not sure what you mean buy "D" shaped end, but I just disconnected the outlet side of the BPV hose (where it connects to the intake) and slipped the valve over the end so that it lets air out, but not back in. You may have to silicon or tape it. Also, don't forget to plug the hole inthe intake.

I know that mine leaks because of the hissing sound that comes from it while I'm spooling up. I think that the stock BPV just plain sucks. I am going to get an aftermarket bypass valve that recirculates with a larger openning and that hopefully doesn't leak. It would be nice to open-vent, but I don't see that happening without a MAP or engine management.

I was also thinking that there must be a simple way of reducing the fuel dump when you open-vent. The Joe P. FPR was just a vacuum hose and a one-way valve going to the fuel-pressure line so that it bled pressure while under boost. There must be some way to rig vacuum lines and valves to reduce the fuel pressure when there is vacuum in the throttle body, but pressure in the intake line.

Or you could just put the MAF between the intake manifold and the intercooler ;) ...
