4 strokes dont have any more torque than 2 strokes. an engine reaches torque peak when the cylinder is filled the best, and it happens at a lower rpm in 4's than 2's. and compression ratio has no effect on power lost- it makes up what it loses.

and yes, if an engine produces twice as many power strokes in a given time, it will produce twice as much power-and burn twice as much fuel. lets not try and clog the thread about who's smarter, or has been modifying engines longer or whatever- its not a contest.
