Thanks Tommy. My enigne likes to make power starting around 2500 (maybe a bit less) as well. I have no rev limiter, so I have to pay close attention. A few weeks ago, I managed the 2nd to 3rd shift around 80 mph. Working backwards through the gear ratios and tire circumference, it appears I over-revved the enigne a bit at about 6600 rpm.

Darned erratic Stewart-Warner tach...even when it's working, it follows with a delay. That's why I went with the speedometer reading.

I must do some more trials, as this 1st gear launch thing isn't a common thing I do. I'll keep your data in mind.
