Re: Gears - to answer the questions once and for all

[Why wouldn't you do a full throttle run in overdrive to get top speed? I bet it would be around 160+. I know you don't need overdrive on the drag strip.]


Powershifting into Overdrive is risky. Your trying to overdrive the transmission output shaft at full power...This takes Torque! Every bit the engine can muster to spin it faster than the crank. I have a friend with a built 300Z twin-turbo who blew his motor doing just that. Ease it into 5th or 6th, then roll on the throttle till your floored. Overdrive is not intended for accelleration.
