 What is the highest RPM you achieve on a pass?

Highest rpm 6800. leave at 4800, shift at 6000. P.S. this is on alcohol.

 I'm showing you're making nearly 160 PSI at 6800 RPM. For a gear pump (Waterman, Kinsler...) that's no problem really. If it's a traditional Enderle/Hilborn style pump, I'd put bigger nozzles in it.

.028's and a .058 pill instead would be the same tuneup but with 40 PSI less pressure at the stripe.
