Warlock, That spec sheet only shows Peak Power & Max Torque, it doesn't show how high you can actually REV the motor, that's what the Red-line is for, & there IS a difference between Peak Power & Maximum Revs!!
Just as an aside, there's an often used saying around here to the effect that
Power is How Fast you can hit a tree; Torque is How Far you will move it when you hit it!! :shocked:
Revving your engine beyond whatever revs deliver Peak Power or Max Torque might not add a heap more acceleration or grunt to whatever you are doing because those are the points where the engine will be at its most capable in delivering power or torque, but at the cost of decreasing efficiency revving harder can add to your speed as you (slowly?) wind the revs out beyond the Peak Power Revs right out to the Red-line - hey, if there wasn't anything controlling that (like was often the case on old school non-electronic motors) you could probably keep on revving harder than the red-line & going even faster & faster, at least until the valves started bouncing or the engine blew up!!
