Running Like Crap Unless I Flog It

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.

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.

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 :woot:

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 :)

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.

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!

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. :devil:

      Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
