Yeh, a person that co-drove with me in Vic in 2006 or 2007 competed in the NSW the year after and talked how there was a silver GTSt competing. I think your car has a gate or is noisy as hell too ?

Yeh, was the Vic manager of P1. He was running an Aston Martin Vantage. He traded down form a cool mans car to a upperty wooftahs coupe! :D

Truth is I love that Vantage so much it hurts! :P

Its not being run as a BOV but rather a boost limiting device. Basically to mimic what GMS had to do in teh days of Grp A

Interesting, does it work better than an ebc or bleed valve? does the turbo still need a wastegate.

No, Just opens up at a set pressure eg 1.2 bar the valve opens so manifold pressure cant go any higher, no you dont have to have a wastegate but its a good idea to run them to stop the turbo over speeding.

The Production race cars like duncans run them as a requirement so they cant run more than the factory boost pressure.

Nizpro used to just run a pop-off valve setup and no wastegate back in the early VL turbo days, with success.

No because the full force of exhaust gas is running through the turbine, and with minimal restriction on the comp wheel, than the turbo will spin way harder than what it needs to for the required manifold pressure.

It may help minimize spool time if you had lazy internal gates, external gate will be no different untill the gate opens

Sorry that does not make sense to me, if there is less air there is less spark,less ex gases?

the point of it is to stop to much boost not to decrease power.

if your car runs on 8 apples. the turbo spools up to 8 apples then it finds that A) the waste gate wont let enough apples past or B ) you have restricted boost for a comp.

in point A the turbo keeps spooling to 10 apples and pop goes the engine or you add in a pop off valve and it lets 2 apples out keeping the manifold pressure at 8 apples. its not designed to let 10 apples out of the system only a few so it just regulates the boost.

with only 8 apples in the system the turbo still trys to produce more but it can because they are being let out.

hope that helps but its realy a question for the forced induction party not the show us your racing machines people.

My r34 at yesterday's track day.

Had my ass handed to me by a pack of evo's. 6th in class D, out of 8 cars. If only having the prettiest car took seconds off your lap time....

Those crappy Falken Azeni's you are running aren't helping your cause. If funds allow, try to get some newA050's or even RE55's under that R34 and look out EVO's!!

    • Much less twat-tastic. CF wheels are too garish for civilised use.
    • From there, as the manual says....assembly is the reverse of disassembly, no tricks worth mentioning Much better (for me)
    • In my case, the standard wheel I had was in good condition but the buttons had more wear, so I swapped them across from the original wheel from the car. The plastic rear cover is held on by 4 tabs, and once the wiring is removed you can get access to 2 screws on each side the hold the buttons in From there I just swapped the wiring over. What was interesting is the standard style wheel is 2.0kg but the carbon fibre one is 50% heavier at 2.9kg. It even has a weight inside the wheel at the top to make up for some sort of imbalance in the design. weird
    • Once the airbag is off, to remove the steering wheel.... Undo the 2 plugs into the clock spring, and the horn connector from it's clip. Hit the 19mm nut with a rattle gun (preferably) or if you don't' have one, you probably want an assistant to hold the wheel in place while you use a breaker bar to undo the nut Then, screw the nut back on 3 turns, and pull the wheel sharply towards you. If that doesn't work hit it medium force with a rubber mallet on either side, or possible behind if you can get there. If that all fails (it shouldn't!) you might need a steering wheel puller
    • So, to next task....the carbon fibre steering wheel was either an expensive factory option or a chinesium special. Either way, I don't like either the flat bottom or thick ring style, so it had to go So...to remove the steering wheel.... First, disconnect battery negative and stomp on the brake pedal for a few seconds. Then, remove the small circular covers on each side of the wheel's rear surround to uncover the airbag clips. You need to push something like a flat bladed screw driver through, to push the steel clip inwards and pull the side of the airbag forward. Once you've done the easy side, same on the centre console side. You can see the tab you are shooting for circled in red Then, disconnect the horn spade connector and for the yellow airbag plug you need to get something small under the black locking tab to pop it out, then the connector releases......airbag is off
