When I installed my RFL it would be open at idle. I would step on the gas and I could actually hear the bov shut. I installed 4 washers and that problem went away. It goes off very easily in my car. I don't even need to boost for it to go off. I can just get the turbo spooling a little bit and when I let off the gas it makes a low whoosh sound. It's a lot louder and quicker of a whoosh when I really get on it.

 

check your vaccuum (spelling) line for leaks

 

also dump trucks/cemi's do not have BOV's thats there air brakes bleeding off..

they can run 60psi with no BOV ah good old TEESELLs

 

Shortened spring fixed it.

Abaz come on, you should know this.

If you're running more boost there is more pressure to push the BOV valve up, and also generally a larger intake manifold (more space for vacuum).

Cutting the spring reduced its stiffness so its alot easier to push the valve open, but now at idle the damn valve is bobbling around so I gotta put some washers in there to stiffen it out.

Come on Abaz, don't make me batter you around

 

My point was just, I've never seen a blow off valve for sale that said. "Requires X amount of boost in order for it to work" Its obvious the pressure in the IC pipes are going to be pushing upwards on the valve, and if the spring is to tight it will not open. Most manufactors have adjustments on the tops of blow off valve to adjust the spring load. When I bought my Tial 50mm blow off valve I had the same problem, it would never open, or if it did you could hear large amounts of compressor surge, Even with the boost turned up it didnt make a difference. Well I found out my engine was not drawing enough vacuum, especially after I replaced the cams with some larger ones, (less vac at idle) So, I contacted Tial, and they had a 20 in vac spring opposed to the 24in vac spring, One that would open sooner, one with a bit less tension on it. So in theroy.. it really just matters is how much vac your engine is drawing.

Why are your panties in such a knot?

 

sorry abaz I thought you were some n00b posting and insulting me I've had a rough day. all my ------- fingernails are falling out on my god damn piece of ---- ------- honda god damn ****** *** bitch car. Yes I'm mad I'm sorry bro I mean no offense to you.

But really I think the RFLs were designed for guys pushing 15+ PSI, because the spring is so god damn stiff on them that it would take alot of burst pressure to throw it open fully (and get the whole PAshhhhhhhhhhhhhht noise).

 

Man chacko, all I'm hearing is ---- ---- ---- *** ---- mother ---- *** ---- in your last threads... Obviosly the car is kicking your *** take a chill pill, nobody like the compressor surge noise, in fact I hate it more than anything.

Anyhow, glad you got your problem fixed, I just read your other thread about the 4-8k experience.. I dont know what to say unless you were smoking tire or smoking clutch, because I've never seen that

Glad to see you back ------- ---- ----!

Jeff

 

nhahaha dude
sorry bro

 

Yeah the Rfl type H is for 12-25 psi the type s is the smaller one good to 15

 

cut that spring baby and it works for 2 psi
I lov ethe ------- sound of it, so much better then the whistling crap of the greddy BOV. Now where is Abaz I'm not done flaming at him!
