With any aftermarket intake, most BPV/recirc valves sound really loud.
I had a HKS recirculating with a Mazdaspeed CAI and it was super loud.

Yea dude just get a a short ram or cold air intake and see how your sound is with whatever bov recirculating before you run vta. You can run it vta but you have to be very careful slowing down. Make sure you use yours gears, otherwise you'll pop the clutch in and the rpms will crash and the car will die. It almost does when you follow this anyways but prevents it from stalling for the most part. Anyways you'll be slower if you vta. Just recirculate. Its not worth the problems that may arise from it plus you can get good enough sound from recirculating. My buddy has a type s recirculating on his evo and it doesn't sound much different than it does when he does vta. Really loud. Just think about being faster and reliable more than aesthetics. Then smile and punk your friends

... hmm, come live with me a week and drive with me for a week straight and you tell me if i lost power and you can see if my car dies at all, or runs different. until then, dont post threads like that.
Yeah one of the guys at my dyno day said the same thing "My Car Rips on the Street VTA" He pretty much shut up when I put 5 cars on him.
We had basically the same mods as well as the exact same AP Beta Map at the time. He had a TBE and I had a FMIC with a Test Pipe Only, everything else was the same. I put down 286/298 and he put down like 256/280ish give or take.....way lower than he should have.
You really need to dyno against a couple MS3's with your same mods then see how your car does. I'm only posting what I have seen first hand at Mazda Dyno Days with the majority being MS3's. So out of like 10 MS3's the 3 running VTA each put down 15-20WHP less than expected. My feeling on it is that the car detunes for the rich condition over time and this shows up on the Dyno. Thus people reporting they backfired like crazy at first then now they hardly ever do.
Now do keep in mind I'm not a scientist or auto expert. This is just what I have witnessed first hand and based on that I would never run VTA. Your mileage may vary
If you dont track your car or spend your weekends running 1/4 mile tracks, then losing the supposed 15-20 hp people talk about probably doesnt matter.
I could care less honestly if that is the case. The car hauls ass when recirculated, and it hauls ass when its VTA, so to me a few less hp, if thats the case doesnt matter
If I like the way the car sounds vta, and it runs fine for me, then **** it if I lose a few hp in the process. To each his own!
I think Mattj3636 and I are in the same boat.

First, could we please get a response without the f-bomb and the word faggot in it? I mean does that help your cause?
Secondly, you are basically calling people ricers or fast and furious people, but yet you are doing something that that makes your car slower because you like the sound of it......(ugh)

this is good info. I will agree that my mileage went down a tad, perhaps 1-2mpg at most. And the whole detuning thing sounds like thats the right thing there. good post.
okay well i have dynoed my car with HKS VTA and i dnot have the sheets, and befopre people say I NEED PROOF LET ME SEE THE SHEET and acll me a liar and what not, im jsut saying what iv witnessed in person and idc what you guys say cause i saw it, just like bravnik is stating.
with the corkspotr FMIC/intake/inlet and a bov i put down 274/291 at the wheels. id like to see the 15-20 hp loss, and if its there, i doubt the fmic/intake/inlet added like 50+ hp.

Really? My car does not run for more than 4 seconds when Im VTA, just stalls out. If you read through any of the 300 thread about this you would see there is alot different about running VTA, alot of it in this thread.
Is VTA going to HURT your car, meh hard to say, Its not gonna help it. But if you like the sound go for it. A tune may help the car run stable while VTA.
and the type of BOV. since he wants to rnu the HKS, and theres two of us who run it right now who can abck it up and say it runs the exact same as the stock BPV, thats all the evidence he needs really..
if he said greddy type S, he has evidence it ran like s***,
if he said something else, id have no input cause i ghave no experience with it..
since i own and run the HKS VTA im just telling everynoe how my car is with it and how it runs the exact same

I believe the HKS is one or the other. Since you have get a separate recirculation fitting for it.
