Heres a in car vid running fat on 5 gal of 110 to 2 gal of 93. Tach is in the 6000 to 6700 rpm range. Now with 70/30 mix 110/93 runs way better pulling hard in the upper 6000 range and bouncing off the rev limiter at 7200 in first. I would say the peak power is at least at 6600. Vid no really a good example but it what i have now.
