My example was a stick on a track. That does not have to mean 1/4 mile track which most here run. Also most here run automatics with torque converters. What happens when the engine side of the converter is turning faster than the transmission side of the converter?

These were done sometime ago for a different thread on a different form. One shows the HP and torque curve the other map rear wheel torque and RPM against MPH. Acceleration in G's in each gear will follow the rear wheel torque curves. the yellow line show peak wheel torque / max acceleration for that gear the red line shows where the wheel torque for that gear would equal the wheel torque in the next gear. A good starting point to try and shift at. Also for this example the trans gears ratio were make so there was a 90% drop between each.
