Anders, Yep, I think the good Captain has got a spreadsheet to do the same job. I was trying to see how acurate the program I had was. I think the result is power at the wheels.
Ive added some other DOS based programs which I either havent tried yet or dont work properly under XP.
The one, CarTest seems to be pretty good as it requires loads of info, including gear ratios, drive wheels, aspiration etc and from that you can have a virtual drag race with any of the cars pre-entered into the system or you can add your own...might prove interesting what it shows with regard to the 16V, Willy, 172 and V6. I cant get it to work under XP because as soon as I start the drag race it blanks the screen.
