In the old days, mothballs where made of naphalene which makes a good octane booster but you'd have to use a fair amount. Nowdays they are not made of naphalene because its toxic. So you'd be pretty stupid to put that in your tank. Even if you were using the 'legit' mothballs that was already pretty stupid anyway.

The "proper" octane boosters do work such as Wynns Race Formula and Nulon ProStrength. There is plenty of tests done and it adds approx 2-3 RON on 98 RON fuel. Its the dodgy $10 stuff in a bottle thats good for nothing.

The hub ring primary function is not to support the weight of the car. Its there to center it and I'd say thats about it. Those *plastic* hub rings aren't there to hold the mass of the car - think about it! However when you don't have the rings you have to be careful in centering the rim properly through the bolt holes. Normally any spacer 5mm or more will not let the rim touch the ring. Not that you should go bigger than that on stock studs anyway...

Octane booster sucks because they use MMT - stuff which coats your O2 sensor, spark plugs and pretty much everything else. I would not advise putting methanol in your tank as its extremely corrosive. Adding 10% ethanol would be an alternative however you may need to richen up the car a tad because of the leaning effect of ethanol.

Perhaps uninstall AVG, Spybot and your firewall (or disable the Windows one) and see how you go.

What does the 997 Turbo lap the Nur in? The C6 is equal with the 997 GT3 and thats <1/2 the price too.

^^ Nah that doesnt sound that good compared to others in this topic. Pretty nuts to literally stand on the pedal whilst the car is moving and half his body out the window...

Love the natural V8 sound but I think a pair of turbos screaming like a banshee would still sound better coupled with the 8's sound.....

At those prices I'd go the Goodyear GDS3 as its a top notch tyre in almost every tyre test known to man.

Basically the higher the number, the stiffer it is. 8/6 will be fairly stiff and the stock springs are probably less than 1/3rd of those values. However the valving in the shocks will also determine the ride quality too which people tend to forget. Put a rock hard shock with a soft spring and it'll still break bones. And remember stiff does not mean you got a good handling ride.

If you checked the exhaust backpressure post turbo ie dump pipe, the turbine housing won't affect it much........unless you are saying you measured the backpressure in the exhaust manifold itself?

If you want to be a bit more scientific about it, plumb a pressure sensor where the O2 sensor is temporarily and check the backpressure on full tilt. I guess if its more than a few psi then there may be some perfomance loss.

Hmmm interesting. 1.58' is a damn nice 60ft. However I believe the GT42 is too big for your application!

Was the filler caps still screwed on tight on the battery? Chances are they filled it to the brim (which is a no no) so once the battery starts to 'gas' and heat up during charging, it would have spewed the electrolyte everywhere as you would know. OR your charging system voltage is out of spec causing it to gas violently.

Speed Camera revenue has hit an all time low. It wont take long before some guy chains the bin to his towbar and goes for a drive. I can't see how it promotes slowing down. Go to the eastern states and there are warnings everywhere that raise the awareness of speeding. In SA? Ah just fine em later... bastards.

Geez you could say that about anything, even winding up the boost on your car.

Yep. Most of the time the CPU fan does not run anywhere near 100% in terms of speed or duration in any laptop so they have plenty of cooling headroom provided you give it good ventilation.

^^ I disagree. I've had good experiences with overclocking laptops, especially the video cards.

This should be in the tech section?

... yet the HSV was at the bottom of the pile when it came to Motor's Performance Car of the Year (or some other shootout IIRC).

It has to be in the manifold. Anywhere else and you are not getting a true EGT reading. Thus you are wasting your time as its just pure guesswork from there.

GFB don't make a pulley for the RB series because they believe it'll be detrimental to the life of the main bearings. Pulleys are a waste of time anyway. The biggest 'inertia' mod is the flywheel. You are saving up to 10kg on a mass which is *much* wider in diameter. Thus the inertial penalty is huge compared to a shitty pulley. Don't waste your time on them.

The thing I worry about with the ATP flange is that the wastegate "hole" is not flush with the actual housing. When the flapper is slightly open, it'll create huge turbulence as it backs up behind the "lip" of the flange.

To me bolt on means it fits the stock manifold. However if it requires different water lines/dump pipes then it should be included into the package to be a 'bolt on'.

Basically you ignore the idle readings, whether it'd be 10 or 0 as it is purely engine 'noise. You have to recalibrate the engine knock value if you are getting >20 on idle. This proceedure is outlined in the SAFC II manual. Basically anything >60 is knock. You have to check this by doing a peak recall after you have a hard run.
