Engine "Rough" Horsepower By Bowling

This is simple determination of rough engine horsepower output based on a "mean" cylinder compression ratio. Use this for extreme ballpark use only. Remember, this is one of those equations that work for some cases and leave you scratching your head for others.....

Now, for real fun, grab a-hold of those "hot" figures quoted in racing magazines, etc, and plug them in to see what checks out.........
