tial alpha q bpv for sure... buy it through importimage and it'll probably be just as good a deal as getting perrin's deal.

IMO the standard TIAL is the best bov on the Market. Im sure their recirc unit is great as well. But ugly as sin

Question for everyone..

I have the opportunity to buy a turboXS BOV for my 2010 for $75. From what i understand it is really EFFIN loud and $200 online. I am completely stock when it comes to any performance upgrades but ill be getting exhaust soon aswell as a drop in filter?

Should i wait to purchase or should i hop on the opportunity for future mods? is there anything i should be carfull of when testing it out and installing? or will i be fine just by following the guidelines written on the first page?


great write up and thanks for any help



Anyone have an answer?

I would invest in a Short Ram Intake instead (more expensive, but more functional).
It is what I am probably going to do with mine.
Subtle Blow Off Valve sound without actually having one- thats what it will do due to elimination of the air box and its muffling capability of the stock BPV.
This is from what I have been reading...yes I am a noob too.

Correct me if I am wrong... experienced members reading this thread.

In my own personal experience, when switching, back-to-back, an atmospheric BOV vs. a stock-style recirc valve (on more than one car), there is a very noticeable loss of power after every shift. It almost feels as if the turbo needs to "refill" the intake tract. I know this isn't quite what is happening, but it takes noticeably longer for boost to rebuild after a VTA BOV dumps upon a WOT high-rpm shift.

I would NEVER run a VTA BOV on a MAF-based car unless you really, really love that sound.


(Public Service Announcement - If you have a loud VTA BOV on a vehicle with stock exhaust...you are a ricer/tool. Just letting you know what everyone else thinks as you drive by. )

My JDM STi swap didn't come with a BPV.

Can I just buy a Perrin or a TurboXS by-pass/recirculating BOV?

Yes i should find a stock one, but wondering if running an aftermarket one would be the same, seeing as it does recirculate.

Yeah, a lot of pro race cars don't run blow off valves for good reason.

If I wasn't so poor I wouldn't have one, GT center sections don't really like that much surge.

Yea, I may try taking the line off mine sometime just to test it out. Maybe only for a drag run or two. I've got a Tial 50 and 35r.

Anyone?

Also, I plan on running a bigger TMIC, would it be best if I ran just stock?

The more i look into bovs the more bad info i get on them. . so therefore it is not worth the risk to me.

What do you think of this..

I have a Perrin FMIC and i have a Tial 50mm BOV connected by a silicone hose using the stock nipple on the charge pipe. On idle I run 20 Hg in vacuum so I got the 11psi spring, however it seems the valve won't open up during medium boost. Just flutters. Sometimes it will flutter a little bit, then vent. Can the smaller diameter of the Perrin BOV nipple be the problem? If I run a 9psi spring I am afraid my idle would be unstable.
