questions on not running recirc

[intak3_bLkMs3]

hey guys im considering getting a hsk bov. i know running it in vta will make me run rich and ill back fire a bit and bog some what. but i was wondering does it have ne actuall long term effects cause i want the loud ass blow off sorry guess im an immature kid that whats to be noticed =D. just curios. and any input on the loudest bov in recirc would be appreciated to thanks guys

im running the hks vta, and it is loud, and you will be noticed..haha

but other than the backfires..

i havnt had any problems whatsoever

I dont think there have been people running vta long enough to notice any long term effects. I'd be interested in the answer as well.

The only drawback to this type of valve occurs on cars with air flow meters. Because the engine is venting air that has already been measured by the MAF, the car’s computer adds a little too much fuel for the air that is left, resulting in a rich mixture for a short period of time. This can sometimes result in backfiring....

Long term affects would not be detrimental. Actually I would guess the car would become used to it because the ecu has adjusted properly. Now that is not always the case, on some cars effects could be as severe as random shut downs. Which could be caused by a multitude of things. and Blah blah blah

your such an OG playa AAMguy

i know this already

I tried it for a night...my car had a hard time maintaining idle, stalled a few times. Not worth it to me, so I'm back to recirculated.

 

[AAMguy]

yea i mean their shouldnt be many long term affects considering most of the affects happen almost immediately.

 

[AutoEuphoria]

The only long-term affect I could see would be if you somehow left the hose unplugged or uncapped. If you did that, you'd have an open pathway for unfiltered air right into your turbo.

i would assume the richness would cause premature cat failure, which is a very expensive OEM replacement. I think really that would be the only probems youd run into long term.

i dont think the ECU will relearn around the VTA because its still in closed loop. And to the best of my knowledge, closed loop is hardwired, and the ECU will just stick to the preset maps.

are bov's beneficial to any car? Bad for mazdas, evo's, sti's, . . .

 

[AutoEuphoria]

Ones that aren't recirculated stock. That's the issue...the ECU is calculating fuel amounts assuming that extra air from the BPV is re-entering the system. OEMs do the recirculated thing for noise, emissions, efficiency, etc.

my idle is completely normal, but iv also had 2 speed6s and a speed3 back in buffalo say thats extremely abnormal for our cars and even the dealership (one tech owned a speed3) said i have the first one he's seen that reacts normally to VTA..

and as for the cat...

catless turbo xs dp/rp sitting in my closet waiting for the money to tune when i put them in

im running the hks vta, and it is loud, and you will be noticed..haha

but other than the backfires..

i havnt had any problems whatsoever

my car backfires with forge bpv and i dont have any leaks...my car is weird ....when i go catless i will shot fireballs (shady)

 

[mattj3636]

every car reacts different, lol. i want my MM wisnia!

 

[intak3_bLkMs3]

sweet thanks how loud is the hks in recirc still pretty noticeable?

i been running vta for lik 8 months, i pull a little fuel between shifts to get rid of the poping ou tthe tail pipe.. runs great! kinda still smells out the tail pipe though

been running my HKS on VTA for about 30k miles now with no ill effects.

 

[lantagne21]

I had the HKS SSQV running VTA for a few days. Car honestly ran pretty good if I kept the RPM's under 3k.

Once I started hitting boost, its a different story. The car would backfire like crazy, quick shifts were very jerky (car runs extremely rich for a second and if you shift quickly and try to give a little gas in the next gear, it bogged out for a second).

Don't get me wrong, the sound was amazing, but wasn't worth the car running the way it was.

I know you really can't run the factory BPV in VTA b/c it doesn't completely close during idle and will sputter like crazy.
