This is my first turbo car and thought it would be fun to have a blow off valve, yeah I know... rice. At least it will help when i decide to upgrade the turbo anyways I installed it in place of the stock one and it isn't very loud, it's an ARC (just thought I'd try and be different from others). I've adjusted it and hasn't made much of a difference, actually I hear it in the AFM. Is this normal? Shouldn't it blow out from the valve itself? Will I be able to hear it in neutral when I rev it up? So I can adjust it without having to do laps around my neighbourhood. Any input is greatly appreciated. Thanks.

Go back to ricer town until you figure out what a blow off valve actually does!!! Besides making cool little noises. https://www.nopistons.com/forums/pub...1047683358.gif

I didn't like the loudness of the blow off valve, so it got piped back to the I/C Piping.

Well when you only run 10 or less PSI it isnt going to be very loud. Are you sure the BOV is opening?

you guys could give him an actual answer instead of beaking the guy off, first off ARC bovs are not very loud but you do notice a WHOSSH noise, second off, check your vacumm line and make sure you have a good vacumm, with out proper vacumm the blow off valve will not open, if all this is good and you want a loud BOV, i would suggest the HKS SSQV, turbosmart megasonic or supersonic and the turboXS type H, the RFL is crap

and you could try giving him good info.



HKS SSQV is balls, spend like $300+ on the piece of ****, and how is it made? with a crappy paper thin rubber bellows inside. A rubber bellows THAT SHATTERED AT 17PSI ON MY CAR.



as for the TurboXS TypeH-RFL, its a good blow-off valve, if you have common sense, its a metal cylinder moving inside another metal cylinder, therefore you need to grease it every now and then to prevent siezure of the internal cylinder. It is the best, most effective, simplest design. **** HKS and there crappy $300+ paperweight.

Thanks for those who actually had some insight. It's greatly appreciated.

was it hte new style or the old style of hks that you wrecked? i have yet to see anyone wreck the hks ssqv bov, if you still have it can you post pics?

I agree with kevin. I have herd of about 3-4 people breaking the POS rubber diaphram inside these things, HKS is overpriced ****.

my hks was 200 new

really now...thats something new https://www.nopistons.com/forums/pub...IR#>/blink.png i never knew that https://www.nopistons.com/forums/pub...1047683664.gif i always thought the SSQV would be one of the best BOVs around on the market...guess i was wrong :(

i still have the stupid paperweight SSQV somewhere. but if i find it i might just throw it really hard at something, so i dont feel like looking for it.



everytime i mention what happened to mine i normally find a bunch mroe people had the same problem, and most switch over to the RFL style BOV (not the actual RFL but the cylinder in a cylidner style.) it's a LOT better then the stupid rubber diaphragm.



kevin.

Then there is my cheap ass Home Depot check on the stock valve ($7).

What does that do now?

Its the stock Bypass valves with a Home Depot racing 1-way Check valve on it. Casue the stock one is made to Leak(reroute) used aire back into the TiD, this way you can have it Vent atmospherically without a Vac leak.

thats pretty cool what call did you have to do to it

If you just want cheap noise get the cookie cutter Blitz job. They are all over the place cheap and already mounted on the pipe.

The type-s is a really loud BOV, but anything over 12 psi constantly and you will break it. Really nice sound IMO.









*I too also hate the SSQV and HKS in general. Never had good luck with any of thier parts. THey just always seem to never fit right or be made very cheaply.

jwhorndog - can you give pics so that we may see how you hooked it up and possibly help you out here.



XS power type RFL is well you get what you pay for. The release hole is so tiny it can’t possibly vent out the pressure quick enough to stop compressor surge on any moderately boosting car. Go with a good name brand 40mm+



The only issue I have had and others with the greddy ones are the tension adjuster spring striping out. Then you have to take it apart and tap the inside again.

Never heard of a problem with the adjusting screws for the Greddys. I never had a roblem with it untill I started boosting a liitle more than it suggets.



The RFL I think is okay. Its about the same size as the type-s. It is at least better than the SSQV

SSQV is "ok" for lower boost levels IMO. We've got quite a few guys running them..we're actually putting one on a miata project going at 14psi, so we'll see. I haven't heard of anybody(besides those of you here) who have busted one...but I just looking at them and it just feels cheap.



The RFL is a great unit for the price. Many of these running around on our cars...if adjusted and maintained properly..they take 15psi w/ no problems..and has a good sound. I'm not a fan of the adjustment discs, but other than that..it's good.



GReddy BOVs are nice units, well put together..haven't played with the new type-rs unit...but the type-r and type-s both held there own until put past the recommended limits...



I'm using a turbonetics godzilla unit... we'll see how well it holds up after i get a couple thousand miles on it,lol..but it does have a great quality build and seems to be a good unit..i've heard mixed reviews on turbonetics parts (IE: delta gate...POS IMO)



I used a Bosch 32mm unit on my protege when I turboed that ...ran 6psi most of the time, sounded great..and only caused compressor surge at around 9-10psi..it's good for $75,lol. Oh, the "anodized" version that I had ended up getting corroded and I wasn't able to adjust the bolt to tighten/loosen the spring...but again..it was only $75.



Hope that helps a lil...

As far as why yours may sound different, other than it isn't a loud unit...you just want to make sure it's installed correctly. Make sure the vac source is good and is hooked up properly..if you vented it back into the intake...it's going to very quiet...

Did I miss the memo?



I will have to admit I have not played with a Type S in my hands to know the how large the flange outlet is but I played with a XS RFL about 6 months ago when a friend brought one and it had a outlet flange the size of a quarter.

I dont know what kinda RFL you looked at, but mine is a little smaller than the size of a half dollar.
