After reading many threads on different blowoff/bypass valves on here, I can't seem to find a consesus, so how bout a vote!

I want to replace my stock valve and replace it with something aftermarket (that doesn't leak) and is the loudest. I realize venting to atmosphere is ALWAYS going to be louder, but I've read enough to be certain I don't want to do that. I know some people don't want loud, and those who do are often willing to deal with the A/F issues associated with VTA, well I'm not so that's why I'm posting this poll.

I'm listing basically what I think is best based on what I've read. If you want to describe the sound or your opinion post away, or if you think I forgot one, mention it, but remember only CLOSED LOOP!

I realize the Greddy RS is new so very few have heard it, but it has potential so I'm including it.

 

alot of the sound depends on the type of intake you run

 

You can always run a dual setup. You get the loud whooosh of a bov and you don't get stalling from maf issues. I have a mazdaspeed protege and an evo and on the protege I am running a turbo xs rbv25 dumping back into the intake and a greddy type s on the perrin intercooler pipe that is venting to the atmosphere. I get a loud bov sound with no stalling issues. Lots of people have been running this setup on the mazdaspeed forums and it works nicely, although it is more expensive. Another option is a dual port bov like one from http://worxtuning.com, you can adjust how much it vta and how much it puts back into the intake, 25%-50%-75% etc. Just a thought. I have yet to decide which setup I will run on the evo since I just got it.

 

anyone hear anything about the APS vavle? it does both recir and vta

 

Dunno about the others, but I have the HKS SSQV with recirc and the HKS RS intake, and it's loud as hell!

 

greddy type rs recirculation thing came out already? i thought it hasn't been released yet?

 

It hasn't to my knowledge, but it's not hard to make you own tube to recirculate. Took me about 2$ and 15 minutes in Home depot.

 

pix? what parts did you use? i'm interested in this... mines VTA right now... would be nice to have it recirc..

 

I have the APS and it's just loud enough...not nearly as loud as the HKS though...that **** is loud!

 

what's so hard about it?

close off your stock bov line, open it, mount your bov onto the upper IC pipe, there you go.

ready to stall out in 10 minutes.

I do like the idea of twin BOV, one at the intake recirculating and one at the IC pipe VTA.

It's makes sense. Also this way you could run your car at high PSI, 22psi, set it and not have VTA Flutter.

 

who cares about the loudest bov.does that make you faster???

 

Nope, its more of a psychological thing. What i mean is that the louder whoosh sounds makes u feel like ur going faster, but ur not. Crazy how the mind works

 

Cuz its super mad tyte yo! And it add 100hp to the wheels mane!

 

Coming from John AKA MR. Las Vegas BLING All show no go 13s 4ever himself.

 

Go buy a Honda Civic and put a Fart can on it. They sound real fast also.LOL
