Acceleration Simulator

The following default data is for a stock 1999 or 2000 Venture. You can fine tune the input parameters by typing over the default values and initiating another run. Have fun!

Auto Recall of Last Run

Notes:

Check Auto Recall of Last Run and all form settings and values as of your most recent "run" (after clicking the Go! button) will be automatically restored for you the next time you visit! For this to work, your browser must be configured to accept cookies.

Be sure to select the desired memory location before clicking one of the memory buttons (Recall, Store, Clear).

Launches are clutch-slipping with traction control, meaning RPM will stay at or above Launch RPM, and if torque to the rear wheels exceeds available traction, torque is reduced as much as is necessary to "prevent" wheelspin.

Inertial forces of the flywheel, engine reciprocating assembly, etc., during launch are ignored, mainly because I don't know how to correctly integrate them into my calculations.

Be patient after the results window pops up. This simulator (minus the form) is implemented entirely in client-side JavaScript (your computer executes it). On a 200 MHz Pentium running Netscape Navigator 3+, 1/4 mile results can take 5-10 seconds, while top speed results can take up to 30 seconds or so. Microshaft Exploiter may take 2 to 3 times longer.
