Running Like Crap Unless I Flog It

[tomgtr]

Hi everyone,

I recently bought a turbosmart bov, so yesterday getting ready to install it I removed the stock bov plumb back pipes and blocked the holes in the remaining piping, so that my stock bov would vent to atmosphere. The car now almost stalls when it idles blows lots of smoke and backfires when trying to drive.

If I floor it, the car takes off fine and the only way to make it idle is continually rev it.

When i checked under the bonnet I noticed if i put my hand over the bov hole the car idles properly..

Any help would be awesome, is it just the stock bov trying to vent to atmosphere thats causing this and will it fix itself when I install the turbosmart bov?

Thanks

Yes, your new BOV is causing all the problems, as it creates an air leak out of the system that the AFM and stock ECU can't account for..... Get rid of it.

[GTSBoy]

Not to mention that the stock BOV will let air in at idle and light loads.

Why people f**k around with aftermarket BOVs is a mystery to me.

[Hadouken]

Coz it goes pppssshhh. Don't you have a anti stall adapter or some shit.

I like the stock bov sound.

[N1 RB26]

yeah it's the bov i did that to mine for little while before i put on the ssqv did all the exact same things but the car does eventually adjust to it. mine did and stopped stalling

[Piggaz]

There should be a automatic link to a page when someone types 'BOV and problems'

Rip off and throw the aftermarket one where it belongs.... In the bin!

I've actually got a copy and paste space where this is. Read on.

I love these threads.

You love the noise - and put the BOV on the car to be a wanker. Its scientifically proven that if you're a wanker, the first thing you do when you buy a Skyline is install a vent to atmosphere blow off valve, to advertise the fact that you are indeed, a wanker.

Do you even know how the Nissan air intake system works? There is an AFM that measures the air entering the engine. The Stock BOV recirculates FOR A REASON. When your duck whistle, twisty whooshy twirly, dick pulling, sparkly, spinny, shiny, noisy, fuleh sic, wank off valve opens, it dumps air that the engine has measured and allocated fuel for. When only half the fuel gets into the cylinder because the air it measured is at the street corner where you sped up erratically and backed off because you saw some women on the corner, thinking that when they heard your BOV they'd get naked and run and dive into your car, the engine is now overfueled and under oxygenated, and stalls, backfires, and carries on. You know why? Because you've created a MASSIVE AIRLEAK on a system that will not run with airleaks.

Do you like that fact that you will foul your plugs constantly?

Do you also like attracting the cops attention?

Do you like the risk of being defected and having to pay money for a BOV that didn't need to be there?

Do you like the fact that you are just making skylines more hated? (And don't worry, its almost a guarantee that you'll drive through the main street of town making it release "because you like the wank off sound")

Do you like it how women love the sound, get naked and dive into your car as you drive past?

Do you think SAU will be happy about another "My car is running rough, I only installed a duck whistle, twisty whooshy twirly, dick pulling, sparkly fuleh sic wank off valve" thread

They should create a database script that bans people that install BOVs "just for the sound" or complain when their car runs rough...

I'm was running 300rwkw and had the stock BOV.

Good luck with it though.

End of the if you insist on running it you need to tune car to run with it or else you will always have problems.

Is this not how one gets women?

c'mon everyone knows BOV's don't get women naked, screw the bov go block it off and run a metal intake pipe and go tu tu tu... doseing gets chics naked lol

[bubba]

Yeah, chicks dig pidgeons.

[GTScotT]

The simple answer is, the BOVs re circulate air on low throttle and idle areas (they are open).

The ECU is tuned to run well while this is taking place.

Block the recirc pipe and the car will run like ass because the system has a big airleak.

It runs fine when you boost it because the boost pushes the BOVs closed and you have a sealed system again.

Hook it all back up or get proper aftermarket choof choof BOVs so you can get teh ladies.

lol I bet this guy wasn't expecting to be owned so hard for a seemingly harmless thread...

what is wrong with stock BOV sound? they sound fkn amazing on my gtr, I reckon the next upgrades u should get are:

22inch chromies - with spinners

a Queen Street paint job - candy apple pink or toxic green

and maybe lower the car about 10 inches so its undrivable.

That should get u all the attention u need

[The Mafia]

Ahaha 22 inch chrome spinners!

That will actually fix the stalling problem too. the reflection from the chrome diffuses the air escaping and causes the ECU to reroute the encryptions and adjust the stall converter.

[bubba]

I thought it was because the spinners counteract the effects of gravity, thus preventing the car from stalling.

Seriously though, atmo bov's are gay and not necessary. On my 32GTSt I've just gone to a full 32R cooler setup with the twin bov's and recirc pipe, welded a 2" return for the bov's to my stainless intake pipe and running a stainless mesh pod.. It's actually quite noisy!

[Borci88]

The douchebaggery in this thread is incredible.. and it's not coming from the OP.

[wolverine]

lol I bet this guy wasn't expecting to be owned so hard for a seemingly harmless thread...

If the OP searched he would know that any BOV thread ends up degrading to something like this.

Unless the OP made a search and thought fark it....Mafia has been a bit quiet lately.

[Dylaan]

who needs a bov? block that shit off with a coke can braah..

mmmmm

stock bov to atmo goodness.

Not to be too critical, but most intelligent people would have worked out what it was after you put your hand over it and the idle returned.
