redline/peak H.P/ & H.P curve-When to shift?? :) intresting???

Even if the engine power at your high redline falls below the power you would land at in the next gear, the car will still accelerate faster in the lower gear.

You see.. these chassis dynos that we all use, despite what most understand, are actually measuring the *engine power* AT the wheels... not the *wheel power*. If you were to measure ACTUAL wheel power, you would see how ridiculously more power there is in lower gears then there is at higher gears... but since we are measuring engine power AT the wheels, we see little to no difference from one gear to another on the dyno minus the effects of altered engine load and driveline friction losses.

Shift as high as you can without hurting your engine and within logical reason. Do not skimp on the R's unless there is a solid mechanical or tuning related issue
