The quick and dirty? There's more in it. Past 5800rpm the A/F ratio quickly shot up to almost 14:1 so we didn't push it any further. Up to 5800 it's still building strong linear power and with more fuel-- it should be good for a couple more hundred rpm.

Base fuel pressure is set to 44psi (no vac)

Timing is low 30's (no knock retard, yet!)

This was with a 58mm throttle body. My Arizona Speed and Marine monoblade is still awaiting repair.

I can't seem to download your link. Can you post it another way, or scan it possible?
