Very interesting, but mind Boggling, amazing how even back then, they had the tech to work it all out,,,, nowadays, they cant even build a car that wont fall apart if you sneeze on it,,,lol.
Justin, did you get my PM yesterday?. just wanted to check as I have been havin some probs gettin the forum to load for the past three days, so did not know if you got PM or not,,
Cheers,,,,

great read, even if some (ok a lot) went over my head
MPH = 225 (hp/weight)1/3 and ET = 6.290 (weight/hp)1/3,
So basically if the car is perpendicular to the obtuse angle of the road,i had a leak 25 mins ago and my aunt is called jean then i should be faster than you!!!!!
Ben.
lol.. thats me out,,,,lol
Also have alook at this -

This guy used to belong to a forum I used and built this downloadable model for all manor of calculatons - its been proved to be extremely accurate at the Pod!
Yeah Tom's stuff was always very good, need to know a lot about your car though to use it properly, ie gear ratios, frontal area, change points, etc.
Then you have to adjust the shift times, and a few other variables to get it to match what you have already managed in the car, once you have the model specific to your car then you can take a guess at any changes etc. I used it before on the Rover and it was pretty accurate, though I've now lost all the data and can't be bothered to look it all up again, working out the frontal area is the most tedious bit as you normally can't find that online, if you can find Cd and CdA though, then you can work it out.

Guys, try this link for the 0-60 times...
http://www.060calculator.com/
This works out pretty close to mark....
It was within 0.4 of a second of my actual time, which is explainable in driver errors/gear changes, I suppose...
nb for working out the cube root, use google... type "cube root of 0.23721" and press enter... VIOLA!
0.4 is hugely off - it takes a lot to remove a 10th of a second.

sorry, just logged on to the forum for first time in a long time and searched for threads I'd posted in to get a grounding, I'm with Dave here, 0.4 is a ridiculous amount to be out either on a 1/4 mile or even worse a 0-60, tbh you could e-mail your spec, drivetrain and tyres and I'd probably get it just as close lol.
