G'day guys,

Came up with an idea that I have tested and works.

For all you people who have externally vented BOV it will stop your over fuelling and stalling.

What I did was run both the stock and an aftermarket BOV. I found that the aftermarket BOV was not venting as the stock valve was letting all of the air out before it reached the aftermarket one.

To alleviate this problem I placed a thin metal plate of the mounting for the original BOV (whre gasket is), then I drilled a drilled holes in the plate so it would limit the air going through the stock valve. This inturn let the stock valve vent under low boost back to the intake to stop the engine over fuelling. But when you hit full boost the aftermarket blows out a majority of the whilst the stock valve only lets out a small amount of pressure.

And if you call now, you will receive 2 packets of 2 minute noodles free!!!!!!

Thought this would help.

Ya!! you champ man!!

good job, can't wait to try it on, by the way where you get the thin metal to place in the gasket place? and how big you drill the hole? 1/8" or ?

thanks!

BTW, where is my noodles? ;)

I pulled the peice of aluminium of a old camera that I was going to throw out. I drilled a hole with a size 12 dowel drill bit.

I am thinking of even going to a size 10 to see how it goes. Go samll and make the hole larger for your needs.

Just curious, but say you still have the stock BOV fitted and want to 'upgrade' Would it not be a good idea to shop around for a Hybrid kind BOV that vents both to Atmo and internally? You may not get as loud a "Pssssht" sound I suppose, but wouldn't that contribute to eliminating the mixture issue?

Also, would a SAFC correct the issue if you had a pure atmo BOV?

yes, an aftermarket computer will fix the iddle problem; such as S-AFC (even the early model AFC will do the job), Power FC. or you even can spend some money on iddle stablizer (not expensive though..), depands which way you want to go consider the $$ issue.

yes, you can get the hybrid of BOV, but chance is you don't like the sound, i.e. I like the sound comes from Blitz BOV, so I will try to have it installed and try to have stable iddle. btw, don't you know the blitz BOV will increasing 10rwkw? just j/k :mad:

This is basically for a mod for people who have externally vented BOV and have the shits all the time with bad idle, stalling, flame throwing etc. If you have a aftermarket plumbback no need the do this.

Beleive me, this works or not if you like stalling:D

    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
    • I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option 
    • You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)
    • I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.
    • Heh. I copied the link to the video direct, instead of the thread I mentioned. But the video is the main value content anyway. Otherwise, yes, in Europe, surely you'd be expected to buy local. Being whichever flavour of Michelin, Continental or Pirelli suits your usage model.
