Hey All

Can someone explain how CC's relate to power? The reason I ask is the 30.5cc engine (1.9ps at 18000rpm) from FS seems to have much less power than most 26 or even 23CC. I know a tuned pipe helps, but what's the point in a 30.5 engine with poor power, do you get more torque? Is there a simple mod to the engine that helps? I've read a couple of post that suggest a different coil.
