In that case you are correct I didn't have a manual to hand and used the figures for a Getrag 240/5StuBeeDoo wrote:My owners manual says 0.81.march109 wrote:Assuming 5 gear is 0.84

Manufacturers set speedos based on a 3% tyre slippage on the road, which might be worth bearing in mind if your sat-nav says different. . . but with 750bhp you'll have broken something before you get there

Can anyone suggest how to test if the boot lights are staying on with the boot shut?

does anyone have any specs of gear ratios on BMW boxes? in my case, E34 M30 530 and 535i boxes are of interest

IIRC there was one car on here that was timed with proper gear and got to 165, but that had over 300bhp.rob_htid wrote:you guys have no faith in me do you lol
I'm no expert, but I'd have thought for every 10mph above that figure, you'd need another 100bhp.
This is why I no longer drive an E30......
i should piss it with 750bhp then. we will see. il do a build thread when its done, not to far off now
