Compression ratio calculator?? And power figures?

Jburch, i really was never to good in geometry, math, multiplication, or division lol. I googled a couple formulas, and they all seem to come out right about the same. Oh any one have a guesstimate, on my horsepower, torque figures? Just a guesstimate at where im at, crank hp, or rear wheel horsepower, really doesnt matter, i know its not much, just looking for a close estimate?
