The rich swing is after shifting, not after spool. There is no table to dynamically adjust fueling immediately after releasing the throttle, because the stock setup uses a BPV, so there is no need for that table.

That's what speed density is...or are you referring to something else?
Blow through can use an atmo BOV as well without any negative consequences.

ok i wa reading previous posts but couldn't find what i was looking for. i'm running a stock turbo on a 2010 wrx, with a perrin front mount and a injen intake. Would i be better off keeping the BOV i have, or should i upgrade it? I'm also going to get a tune after i install the FMIC.

Default Greddy BOV question

I purchased a 02 wrx and it had a Greddy BOV on it. I notice that the car seems to run kind of poor until the turbo kicks in, almost like it has no get up and go. I do not have the stock recirc valve, but I noticed some of these BOVs can be used as recirc valves also. Can anyone give me any advice on this. If this is the case, can you describe to me how to hook it up as a recirc valve?

Also, if you have a cold air intake with a BOV, does this maybe even out the air/fuel ratio that the BOV is messing with. By adding more air, does it even out the fuel delivery. I have a full AEM cold air into the fender well.

Those BOVs have attachments that let you pipe the ventilated air into a hose, which you can then run to the post-MAF intake. Chances are your problem lies elsewhere though.

Yea, that did not help one bit, no offense. I asked how to hook up my Greddy BOV as a recirc valve, if it is possible that is. I also asked if my CAI would even out the extra fuel being dumped from my BOV as it is. Sometimes the stuff you search just does not answer the question you need answered.

They have a primary and secondary valve to make sure the right amount of air is being released.

If you're talking about the HKS SSQV, skip it. It's known to leak, a lot.

Your mod path has gone way off course. Forget about a bov. Ditch the intake. Pick up an AP/down pipe combo.

Impreza WRX's are recirculating bov? Did I read the original post correct saying running a atmospheric bov is safe? Pretty sure I misread that...

technically its a bypass valve because it is fully recirculating.

is it safe? well its not "un safe", but it will most likely make your car run like ****. it wont blow up, but it'll suck to drive.

is the noise worth that?

Nope. I was just curious on what the first post mentioned. My VR4 is recirculating and I keep it like that. Running a open (atmospheric) BOV makes the 3000gt's run pig rich and I always kept my VR recirculating. Didn't want to have to throttle bump every second when I am at a light.

Please help.
Just got my car diagnosed. Was told my blow off valve was not recirculating. What should I do to?
Should I get the re-circulation kit? Or just buy a new bov/bpv completely? Or was told another way to go was go back to stock bov/bpv? Also, if I do have to buy one, either the kit/new, where can I buy them from? Base prices? Note: Forgot to say that my car came with a Blitz BOV when I bought it. I have not modified anything on the car.

I am more concerned in the health and longevity of my 2005 sti, more than mods at the moment until I can actually afford to lightly modify. PM me or post reply here.

Thanks,

Tam <3

Go back to the stock one. You can typically picked one up on the classifieds here for ~$20-30. It's going to be the cheapest, easiest, and best solution.
