How far to rev this 273 commando build

In this day and age it's easy to figure out shift points 'n such. There are several vehicle "performance gauges" I have a used G-tech for example. Anything that measures torqu or acceleration will do ya. You generate a curve for RPM in a known gear, and then plot that curve corrected for the other gear ratios. "Where they cross" is where you shift

Similar to this.......One axis is (here thrust) can be torque, acceleration or HP, the other axis speed or RPM.
