Knife edge you siad you could not think of how to get lower than a 1:1 rod to stroke ratio?
but you then wrote one that is 1:2 as far as I can see. If the rod is exactly the radius of the crankshaft throw and the piston can come down inbetween the counter weights (they just need to be spaced out) then the rod length is half of the total stroke length.
Anyways if you want better power try to get the highest rod:stroke ratio you can (i.e. you want 2:1 not 1:2) this leads to better combustion control as the piston accelerates more slowly away from TDC and puts more of it's force into the crankshaft and causes less friction between the piston and cylinder walls. of course the offset is that with longer rods you have more weight in the engine so don't try to get any more than 3:1 the golden ratio is between 2:1 and 3:1 where the advantage in friction and increased power transfer is highest without being overly heavy.
Oh and hoot-hoot you should only talk for yourself I consider myself to be a engine builder/designer by hobby. However I like to find my own designs and ways of making engines better (cause I don't really like the fundamental flaws of current reciprocating piston engine design)
Power, whether measured as HP, PS, or KW is what accelerates cars and gets it up to top speed. Power also determines how far you take a wall when you hit it
Engine torque is an illusion.
