JIMIH..

With a external venting bov like the one that you got, it will stall no matter what you do.

If you tighten it a bit, it might stall less, but it will still stall or almost stall after it blows off due to the whole air flow meter issue.

To Tighten the GFB Mach 1, there is a screw on top. If you turn it clockwise, it will tighten it and push the piston a little lower so that it is completely closed during idle.

But your car will probably still stall in a situation like slowing down to a set of traffic lights or something.

If you are in sydney, and you want help then let me know..

I can help tighten it or whatever...

I've got a plumb back GFB bov on my car. It's briliant. No stalling, heaps better response when accelerating.. and a nice muffled khhhhhhh type sound through the pod filter during gear changes.

If you can still return it, and you want the psshhhtt sound, then see if you can excahange (with money on top) for a Hybrid BOV..

this way you will get the sound and no stalling.

cheers for that :)

i'm in Perth but I tightened it and it doesnt do it as much now ... I can sort of keep the revs up a little as I'm slowing down to the lights to keep it from stalling.

It's not as bad as it sounds, but it's just a little annoying sometimes ie. if you stall it in front of a group of people :)

My car used to stall too... It may be the BOV or bad tuning(e.g. air/fuel ratio,do u have a SAFC??)..

Anyway my POINT is it is REALLY DANGEROUS.... My car stalled once when it was raining and my car spinned 180 and skidded some distance and nearly hit another car...Imagine if it hit a passerby.... Lucky me!!!

I suggest u either solve the prob or change the BOV..... :cool:

I've heard that 'lines are very sensitive to externally venting BOV's so I got one of those GFB hybrids that plumbs back some air and vents the rest. Works awesome even with light spring pressure and it has never stalled, plus it's not too ricey. In fact the car runs better than with the factory valve, I think it must've been leaking or something

From memory I think one of the features of the SAFC is to allow for an atmo venting BOV.

Yeah here is the quote from the Apexi USA website:

" On hot-wire vehicles, the Deceleration Air Flow Correction function is capable of curing the erratic idle and stall problems associated with open-atmosphere blow-off valves on hot-wire air-flow meter systems."

Taken from here:

So don't keep stalling, invest in a SAFC today. I'd also assume the PowerFC can do this as well but I've never looked into it....

I tried setting that but it does nothing!

i used to have problems with my car stalling... however it was due to the afm. Its rather "exciting" when the car stalls infront of incoming traffic in an 80 zone...especially when you needed a new battery as well and when you tried to restart the car it would not crank over!!////:dump:

      WA PITS: Am I screwed?

      I'm not up to date on the latest, but for basic modifications like pod filter, lower springs etc you can get a modification permit at the time of inspection.  For more serious modifications you will need engineering.  Intercoolers used to fall into the mod permit rule but its been a long while since i looked it up.   Either way you will be able to get it registered, just a case of $300 vs $3k .

      WA PITS: Am I screwed?

      Hi everyone! I’m the new owner of a 1996 R33 GTS-T, I’ve purchased this car over from Queensland and brought it to Western Australia and I’ve found that there is a hole cut out in the engine bay for the FMIC that enters into the wheel well (fender liners are in the boot). For anyone that has had to get their car over the PITS here, will this be a major issue?

      100% accurate!  We are a pack of know it alls....  But, I bet people go to you when they have a problem! I've been on a bit of a clean up rampage too over the past month!  I've thrown more shit in the bin over the past 2 weeks than I have in the past 3 years combined! Anyway, it's all good fun being different! My wife sometimes does not agree!

      ADHD in all form isn't about "can focus, or can't focus" or is hyper active or isn't etc.   It's all a dysregulation. Either time feels to be stationary, or time just vanishes in a split second. We are either under focussed on the task at hand (as we're over focussed on our surroundings) or we have no idea an atomic bomb went off beside us as we're so hyper focussed and locked in on things.   Not to mention the rapid fire thought process. What it takes a "normal" process to think up a solution to a problem, ADHD will be able to give you 5 different ways to solve the problem, and the pros and cons of each. While we can be highly impulsive and lack the ability to "control ourselves" we can also become paralysed with the inability to make a decision for ourselves. While most of us have an OCD like requirement for perfection, we lack the ability often to remain focussed to get things to a perfect state. Those with undiagnosed ADHD as adults, can often find the last part actually stops them ever attempting to do things that they have the ability to do, as the reasoning is often "if I can't do it perfectly, it's not worth doing"   As for projects... Ha ha ha, I still need to take the other half of my wall trim down in the Fiance's office so I can paint it. Need to finish digging and running the back yard drains, my R33, getting the Ninja bike registered (now being sold), the moped project, fixing either of the lawn mowers so they're reliable, along with a myriad of other things.   It's why I've been going through lately and just being brutal and clearing projects off that I won't actually ever complete. IE, moped will go to the tip, or be given away, bike is being sold, Subaru project being sold, some parts for other projects given away. Or I've been making myself focus on one thing at a time, by ticking off the smallest quickest ones first.   There's also a reason by our mid twenties we seem to be "know it alls", as we've all been down some of the weirdest and oddest rabbit holes when you follow the dopamine trail. It's often also why we're more a jack of all trades, but not a master of one.   However, pretty much all of my hobby projects, in one way or another, all come back around to automotive. That's my zen area.
