Got pics?

I've been "window shopping" for some 4 pots.

:down:

BTW got my modified coilovers back from the engineers today. Going to fit the rear Ohlins coilovers tonight (and maybe the fronts if not too dark - bloody daylight savings!)

all i am saying is that after my research into that i have found out that it actually does stuff all if you block your stock bov....

I wouldn't worry about it. There's always going to be people talking about things they know nothing about, pretending they know it all. Let them go and you find out for yourself, rather than what some forum says.

they had a DIY in a HPI or Hot 4s mag the other month with blocking off your stock BOV actually and mentioned how they didn't wanna get into the whole discussion about the damage it may do to your turbo or something. my pod use to make the funny du du du du du du noise but now it's just a rush of air, BOV wasn't hooked up properly.

The BOV prevents the pressurised air between the throttle butterfly and the turbo outlet from blowing hoses or even bending your butterfly. It relieves the pressure when you shut off the throttle by releasing it thru the valve and back into the intake system before the turbo. (or into the atmosphere for those with aftermarket BOV)

This is the rush of air I hear. Portion of the returning air coming from the pod filter, as that air is more dense than the turbo will suck in due to the shut throttle.

:thumbsup:

So the short answer is: do not remove your BOV entirely and block off the mounting point for the BOV.

That's not what they were originally designed to prevent. They were disigned to prevent compressor surge which puts huge loads on the thrust bearings in your turbo. I don't have a BOV on my car running 17psi and i have never had a vac line blow off and my TB butterfly is fine.

Yes ^^^ That too. Forgot to mention the stress on the turbo also. :thumbsup:

You must have a bulletproof turbo. Still, I'd rather retain the BOV.

      After market rear camber arm adjustment

      By Duncan · Posted

      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.
