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.

      Absolutely this. Yes, except not vacuum hose. Something oil/fuel safe is a better idea.

      Like a Stagea, but not as cool! Hope you have enough garage space for this, or is something going to leave to make way for it?

      My BMW E39 528i touring

      By PranK · Posted

      The new project has arrived. I have wanted one of these for such a long time, well before that meathead Clarkson drove one in Africa. I really wanted an E34 but I have some medical issues that mean I *really* can't bump my head and the lack of airbags in the E34 made it just too big of a risk.  I don't know why I've always liked these older touring BMW's to be honest, but man I love this car. She's been pretty well maintained for her 243k's with what appears to be only a single oil leak at the oil filter housing gasket. It has a bunch of updates including later model bumper and headlights, 7 series billion-way adjustable seats and it came with a few spares and another set of wheels with legal tyres. I got a unregistered car permit from the RTA and drove it back from Canberra on Saturday.                   First cab off the rank is cleaning it up for blue slip. I dont know how picky they'll be but I figured I'd clean the headlights, fix the oil filter housing gasket, replace the speed sensors (throwing errors) and swap the OE wheels (the M Sport wheels have a big chunk out of one of the tyres.) I also need to replace all 6 gas struts - 2 for bonnet, 2 for hatch and 2 for hatch glass. The car tries to eat me whenever i open any of these. My plan for this car; Ultimately, this is a budget car. I can't afford to throw lots at it and its because I have another car that I got this, if something breaks its no big deal. I will just maintain and repair it really. But eventually I want to do a manual conversion. It actually looks pretty straight forward for E39's and the trickiest part will be sourcing the parts.  I do need to replace some suspension arms or bushes because wow, she's a floaty old girl. She's also fantastically slow. Like really, really slow. When pulling back out on to the freeway on Sat after a quick pull over I needed to wait until no cars were visible before going.  Oh, and the guy I bought it from had a gorgeous R31 GTS-X in the garage.

      Do you have a picture? I assume it is a breather for gearbox oil as it expands, it should have a vacuum line run nice and high in the engine bay (R32 GTR has it on a top bellhousing bolt)

      By zigrb30 · Posted

      Hi all, I am putting an r33 gtst gearbox into a VL and have noticed what looks like a vacuum barb on the box (on top in the middle). Suspecting that it's a vacuum line but I'd like to double check, if someone could confirm the function of that would be great. Cheers in advance.
