Sounds like we have two different theories here, simply stated 5%-10% over max hp rpm and screaming it. I know cars that turn left keep the rpms way past max to keep wheel speed high. If they ran less rpm the car wouldn�t accelerate as fast coming out of the turns. So why two different theories used in drag racing

It ran within .05 with all three. Your combo may be different. My bet is the more torque you have under the curve, the less the effect of over gearing has. I will test this theory this Summer. Doug

I dont see my car do much in ET on RPM changes(unless its ALOT of RPM)
