define torque

[Lowe119]

 ;D ;) ;D
Just make the horse work faster then. Like a 1000cc single cylinder engine doing 15,000 rpm.  :D

btw - why do engines have peaks at certain rpms? Does this have something to do with 'floating valves?'   iow - what does my R6 lose at 12,500? Compression or something?

Think of torque as the effort required to break loose a stuck nut (or bottle cap).
Think of horsepower as how fast you can unscrew it.
 
Peaks and dips in a power curve are caused by harmonic backpressure pulses.
In a typical 4 cylinder four stroke this usually affects power around 7000 rpm.
