Finally! Data (The Radium King) that backs up what I feel in the seat of my pants at the track It is very clear from those numbers that, for max acceleration (and lowest lap times) you need to get as close as possible to redline when shifting from 1st to 2nd to 3rd , and also possible 4th. You will see that you loose time at every shift, and coasting (not accelerating) also makes you loose time but may be necessary if you are shortly about to enter a braking zone VS shifting into 4th then back into 3rd 1 second later, more lost time from the shift than lost time from the brief coast at 7,000 rpm.

Engine longevity is a different issue and I tend to agree with Stevedox as I try to shift a little early (6,500-6,800) as you might peg redline and then some if your shifts aren't precise. Rev limiter should reduce that occurrence, but I have learned that doesn't always happen If I know I will have to shift to 4th or higher, I will shift a little early maybe 6,000-6,500 just to save some wear and tear...

Enjoy your HPDE! And beware of the money shifts!
