Inviting you guys who've dynoed your cars to try my acceleration simulator. It's not an acceleration predictor, using weird formulas to guess performance. It uses mathematical formulas (f=ma, etc.) to simulate the acceleration of mass over time and distance. It's not absolutely perfect, mainly because of the difficulty I have in turning all the dynamics of vehicle launch (clutch slip, tire slip, angular momentum of engine/flywheel, etc.) into mathematical formulas, but it's very accurate in showing you where you should be shifting, and how power and weight changes affect acceleration and top speed.

I originally wrote this back in 1998, and I know the UI kinda blows, but... Let me know what you think of it.

Usage note: The more torque curve data points you enter, the more accurate the results.

 

Thats very interesting. Do you plan on releasing the source (under GPL or some open source license)? I would be very interested in the algorithms you used for this.

 

It's all JavaScript, and not terribly clean , but help yourself.
