BOV causing stalling at speed?

[T0nyGTSt]

How do I fix this?

HKS gold colour crap BOV.

It's downright dangerous when it happens at highway speed.

have you blocked the standard one

[ix9]

easy. you remove the show-off-valve... they're nothing but problems. and when the rice-value novelty dies off you'll wonder why you bought it in the first place.

I bought mine because the standard one was leaking, plus it was amazingly noisy (even with recirc)... I bought a vent to atmosphere BOV and its alot quieter, and less sensitive to throttle variations too.

R32 GTSt standard BOV's suck arse.

Rice Value: Nil

Practical Value: Heaps

Strichnine,

Sounds like you got burnt by the rice-BOV in the past? I agree that some of the BOV's designed for maximum noise are a waste of money, but a BOV does serve a very useful purpose.

I had mine installed when I had my factory computer and never had a problem, but I know lots of people who have has issues. It seems strange that with similar setups that the results should be so different. Is it related to the type of BOV you buy?

Do they? Everybody seems to say they're a waste of cash for the performance perspective - and the standard one is good enough. Do they actually give any performance edge? Some say they're not useful unless you're running a monster turbo and 300kwrw+ ?

I'd consider one if it actually did something worthwhile. I understand the principles involved and they make a bit of sense - just am curious as to how they hold in practice?

predator666,

Yes they are definately an improvement on the factory BOV, but alot of people do have problems with them causing stalling. I think the stalling is related to the AFM compensating for the air being vented to atmosphere and dumping in too much fuel, but I'm not sure on this.

As I said, I have not had any problems with mine, but if you buy a $400 BOV and it stalls your car then you would think they are a waste of money. I'm not sure what is the difference between ones that work and don't, I have a Blitz BOV and never had any issues.

try playing with the tension

try tightening or loosening.

I had the same problem with my Turbosmart Type III Supersonic.

Tighten it to death will go some way to fixing the problem but the best way is to take it apart and make sure the valve isn't gunked up with crap, oil, etc... Some Graphite type spray lubricant helps. Then put it all back toegther and tighten it right up.

What you're doing is making sure the valve (usually brass or similair), is closing before leaking all of your vacuum into the atmosphere and stalling the motor. This is why tightening the valve can help.

In regards to the "do they help" question, it is a measurable FACT that they help in MOST circumstances in regards to keeping the spool up and being less likely to leak.

Hope this helps.

Best Regards,

Adrian

Burnt: you could say that. All i wanted was the Psssht really loud...

Then I bought my car with a blitz already on it I thought it was the bee's knee's till it started stalling..... bah! nearly f*cked it off altogether before i found a solution... tighten it up to the max, and use the stocker aswell. DONE.

It's not very loud now, but still audible

someone told me even R33 factory plumback BOV will even hold boost application around 20psi?? so unless for showing off purpose, it's kinda wast of money to get an aftermarket BOV

[dojobi]

My stock plumbback BOV leaked heaps, you'd hear it whistle as you drove along. Very annoying. I replaced it with a GFB hybrid - the best of both worlds.
