Hi, my car is a S1 R33 GTS25t and the BOV in question is a Blizt DD. After intalling the BOV when breaking into a shape corners the engine will stave of air and stall on me. I have try this a number of times and it still stall on me BTW the car is AUTO. I think it's the hose overheating or the ECU is not use to the BOV yet. I have reset the ecu and will test some more on the weekend. did anyone have any problem like this before? maybe because i'm not running a pod.

Also can anyone please attach a pic of the engine bay with apexi pod installed with stock AFM.

Thanks in advance.

atmo bov you have. atmo bov no worky. it vents air, the engine expects that air is still be there so it adds fuel / timing to suit however the air is not present so it runs too rich and stalls. fix use stock bov

dude, you can't fix it.

Well, actually you can. Either plumb back your BOV or put the stock one on.

Why would you bother putting a loud fully sik OMG!!!!111oneoneone!!!11 BOV on a auto anyway.

Do you drive around, foot flat, and taking it off the throttle quickly to make your BOV vent on purpose when there are some fully sic chiks around?

Let me guess, you're a poser?

hhmmm

This is why your Fully sic BOV is making your car stall. You run an AFM before the BOV, it measures air that is gonig into the motor and the ECU puts fuel and timing in to suit.. Use a Vent to ATMO BOV and it takes away this air and leaves the fuel behind..

And what do you know.. that fuel doesn't have that air anymore to burn, so it stalls, pops, farts, and carries on.

If you want to run a fully sic ATMO bov, get a powerfc d-jetro and run a MAF at the throttle body.

That'll make the chicks look....

oh and if your wondering why your getting a lot of smart assed answers...Next time, try using the SEARCH function, this topic has been covered about 34568938930295345 times, by people that have no idea about the car they drive. They think you just turn the key and the wheels go magically. And they also seem to think that if you install a Vent to atmo BOV all the chicks will line up and want to ride with you.

lol can't believe I typed all of that.

why does everyone say use the stock? If he wants the sound, he is entitled to it.

It's all about the setting of the BOV. I got a Greddy Type-S and my car doesn't stall at all! It's all about adjustment, tighten the spring and it should stop stalling, but don't tighten too tight otherwise it'll flutter and the BOV isn't actually doing its job.

The only side effect of an atmo BOV is that it'll be rich when the BOV vents, and you may get a bit of backfire, especially after letting off on hard throttle.. but being an auto, you won't get rich conditions on gear changes.

having said that, yeah, he should get flamed for not searching.

Any Tech feed back? thx

you got it within the first 8 words of the first reply

atmo bov you have. atmo bov no worky.

simply put, you wanna use an ATMO BOV... you'll need to purchase a SAF-c/PowerFC and have the thing tuned so that it wont spit the dummy

This can be found by searching and reading, trust me :blink:

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
