Drag Race Simulator for
1/4 mile, 1/8 mile or Top Speed

This simulator was developed by John Bolton.
(if anyone knows his email, I would appreciate it)

This is a modified version of the Drag Race Sim that has the torque converter slip modified.
It will show "stalled torque ratio" (STR for short) on the right side of the pop up window.
Also added a Column for HP on the right.

A reader suggested this modification. Let me know how it seems to work.

You can see the speed of your vehicle as it accelerates in the pop up window.
The summary information for your simulation is displayed at the bottom of the computational window.

Notes:

bullet

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" wheel spin.
