When to shift??? Need help on when to shift. Currently shifting at 6600 rpm with combo below.BTW ran a best of 12.20 at 113 mph. 1/8 mile times were 91 mph @7.8 secs.60ft times were 1.85 fwiw.Dynoed 368/343 hp/torque running fat at 11.0afr. That has since been corrected to 12.90 afr. Guessing hp might have increased to 375/380 hp.Anyways have one more shot before the season ends.Oh one last piece of info on the dyno(while running rich) I was still making hp up to 6600rpm assuming max. hp and that rpms would drop on a shift thinking such drop might keep it in its best range. any thoughts???? input???

I hear on NA you want to run to the peak, and spray somewhat before it to keep the torque higher or something. Good question. I have tried on mine to shift slightly earlier (no dyno so not sure) and lose time, shifting any later lose time, so mine for NA is set at 6850 IIRC, and juice is set at 6700, fuel cutoff is beyond 7k. Thats with a TSP 231/237 .595/.598 112* cam.
