ATM BOV's: End all poll.

[BuudWeizErr]

Since I ALWAYS hear people talking about all the "problems" with BOV's venting to ATM, I want to know, ONLY from people who currently drive SR20's with ATM BOV's.

How many of you actually have problems with venting? Problems that are so bad that you would consider switching back to recirc or installing some crap piggyback fuel computer?

Me... I have small backfires on 25% or so of my shifts and then some larger ones occasionally. But I see no reason to recirculate.

What about you guys?

[Samabra]

I have a Greddy Type R BOV that vents direct to the atmosphere sending its small pressurized bursts of air back to where the creator intended them. I am not an oppressor of air, I prefer to set it free rather than keep it in some medival bondage.......................................anyway no problems at all, however I have my BOV mounted in my fender well, so I have no problems what so ever.

[SWIFT_DRIFT]

I have an older HKS SQV running .9 bar venting atm. No problems but I am using an analog Apex S-AFC so....

[turboex]

I have an greddy type-s on mine and if the spring is loose so that it blows off all the time and real loud ( like fast and furois eclipse) then there is a back fire every time im at idle for a few secs and sometimes when i shift. When i have it tight, (yes you can still hear it fine) the car runs great as if it should, no stalls no back fires no nuthen. runs perfect. I heard the rerouting it back in like stock was better for preformance but we tried this at the track and it made no diffrence at all, and the spool up time was the same to.

I've got a Blitz SS BOV venting ATM with ZERO problems minus the small backfires from time to time, I wouldn't say 25% of my shifts, but more like 10-15%. I am VERY happy with it and wouldn't even consider switching to recir.

[edisapimp]

me likey go psshhh

[SpeedRacer1]

Used an ApexI dual chamber, good design and sound, bad side affects during driving. I only used it for a day, and when I need to show friends how a BOV works. The car will stall after any throttle fluctuation (even tapping the gas to 1000rpms). So it results in me playing the foot on throttle constantly game. I do not have any MAFS compensation device like an SAFC. I also prefer my recirc valve at stock boost for driveablity.

[Zaxx84]

I have a Blitz SS/DD BOV venting directly to ATM. No a single problem as of yet, sounds great too.

[I H8 UR DSM]

I run an S-AFC with mine, and have never had any issues. Occasionally will run a little rich inbetween shifts, but nothing major

[240_Keyy]

no problems to speak of with my Greddy Type S venting to the air. I don't even get backfires all that often and I have no idling problems or anything. I also am just using stock ecu with no piggyback controllers.

[B.L]

I have the hks ssqv and have never had any problems.I get a few pops and some flames sometimes but thats not a problem.

(everybody in Europe and UK use atm bov's and no one has ever had a problem)

[Tai Mai Shu]

I have the Greddy Type S and it just started to become lose so when you just put it into nuteral the revs drop really low, but I just need to retighten the spring on the BOV other than that its fine into the deep blue yander.

[AllTurBo]

I have a Blitz SS. I don't really backfire that often, but my car will sometimes stall if I come directly from boosting down to an idol. Unfortunaltley this usually happens when I am going into a turn or something, which causes me to lose my power steering if I don't tap on the gas to catch the stall. I've gotten used to it and I can usually catch it before it stalls. It just adds to the overall SR driving experience :p

[I H8 UR DSM]

um...then why do have power steering?? That takes away from the driving experience : )

no offense bro, but that statement has accomanied many dumb ideas. a lot of crap happens over there that can just stay there. i mention this merely as an anecdote, not to piss you off or anything.

[MojoMan]

I use the HKS SSQV. No problems. I stoped back firing once I tuned my afc a bit and the stalling doesnt happen even after hard boost driving and going to an idle. I like hurting peoples ears as I drive by at WOT and letting off the gas. Hehehe... s***... it hurts my ears if Im next to a wall.

[SpeedRacer1]

BTW, wheres the poll?

[nrcooled]

My Blitz SS was a bit*h...I stalled all the time even with the spring on full tight. I hated it with all of my being! Then I got the older HKS SQV and I love it. Not as loud as the Blitz but it doesn't have all the problems I was experiencing.

No backfire, no stalling, no nuttin'.

[implict]

I hear my **** backfire alot..... and im still on stock bov... stock boost...... Right now im currently running just a D/p ( 3" )

( i can hear the turbo REALLY good ) :icesangel

Anyone knwo why im backfiring so much??

like when im idleing it does it... and when i let go of the throttle it does it... but when im on it ... it doesnt.

Thanks Jeff.

[Movingviolation240]

mine runs fine 'open' with a Greddy type S, my CA had an HKS and it also ran good with it open. You just have to adjust everything right so that it dosn't stumble when you dump the boost. (basically just get the valve as tight as you can get it and not have surge). If all else fails play with the IAA and TPS and you'll be fine.

Why do u think piggybacks are crap?

[Movingviolation240]

because they are, you can't really fine tune a motor with a piggyback, due to the nature of how they work it just isn't the best way to do it. Either re-program the whole ECU or go standalone (or PFC)

You'll see guys pick up like 40+hp over just an SAFC when they go to PFC or a tunned ROM.

Paul

[vboyq]

well given the obvious price diff. between the two, then the Safc would do its job... fine tune your fuel curve and prevent detonation.

[BuudWeizErr]

SAFC suck.

I will never put one on my car, and I cringe when I see them on other peoples cars.

[vboyq]

hey thats fine and all but i myself won't be able to afford a standalone (wish i could though cuz i would)!

[implict]

SAFC suck.

I will never put one on my car, and I cringe when I see them on other peoples cars.

Whys that?

[BuudWeizErr]

Because most people who will install an AFC will not take the time to tune it right, won't mess with timing, and the glaring factor that I don't trust a computer that modifies the factory fuel curve instead of sets a whole new one.

Sorry, but no.

[Movingviolation240]

A good ROM tunned ECU cost's just as much as the SAFC but has a LOT more HP potential. The SAFC is just a bandaid, good for a quick fix but not a long term or 'clean' solution to the problem.

Paul

[badass240sx]

Well, I just installed an S-AFC II along with an APEXi SuperITC which will allow me to adjust timing +/-15 degrees from 800, 2400, 4000, 5600 and 7200 rpm. I'm taking it to XS Engineering to be tuned very soon and im confident it's going to make for one hell of a setup. We'll see just how far I can go with it.

[implict]

well see i have a tuned ECU ( MINES ) and i need the safc to use my z32 maf..... cause my ecu ( from my knowledge ) wasnt meant for the z32 maf... My ecu already has the fuel curves and **** done to it.. and what do u mean timeing???? ( ive never had a safc so i kinda have no clue what it is for... somone could help me out on that... )

And couldnt you just take it to a shop to get it tuned right? or could u do it urslef....... lemme know

Thanks
