Do let me know if you spot any problems. I'm sorry about the Javascript being all on one line, but apparently Blogger loves to insert br tags everywhere. :/

nice little thing : )
just add fields filling exaples, note or comment in rpm field: torque up to given rpm - constant, also may be a title - calculated theoretical constant acceleration; constant torque model as opposite to contant power (ideal CVT model), where torque and acceleration decreases wile speed increases

may be specify (to be clear) - accel calc. w/o taking into account resistance (wind, rolling)
