Steve made a comment on getting the oil in the rear end heated up. The rear ends today are so strong that you seldom see a failure with them. I remember well that back in the day, you'd see a (front engined) T/F car make a pass, and the rear end would break a couple of hundred feet off the line. A good driver could catch it & get off the throttle before the engine zinged to the moon. The rear ends were out of a passenger car; nothing like today.

Gives you an indication of why teams rarely do throttle whacks anymore - lots going on and I imagine throttle whacks just make the warm up procedure not conducive to good performance. Now, there are teams that give demos - Kalitta (for sponsors) and Tasca (annual car show in Cranston, RI) come to mind - and whack the throttle. But there is no racing on the line when they do that, it's for pure entertainment.

He mentioned stepping on the throttle to activate the timers, etc. does this mean the linkage is not connected during warmups?
