Must be missing something here, I thought reaction time had to do when the driver let the car move? Cant see what RPM has to do with any of it? Can someone explain please? 60ft time I can see, but not the RT...



Its when the light turned green to when the front tires
broke the beams(forward beam)... think of this extreme.
if you idle off the line to 5000 rpm off the line..
which will move past the beam first





Ok, makes sense, thanks



The closer you can get to the max torque of the engine
the quicker it will move the mass
