... to horsepower

uranium67 · 06-30-2009, 01:32 AM

I feel ridiculous asking this, but I need to know how to do this on the go.
How, if possible, do you determine horsepower by the Cu in or even litre's on an engine?

Thanks!

Not really possible. Some of the 1.5 liter F1 engines used to produce around 1400hp, some 600cu.in. aircraft engines produced around 300hp.

they have computer programs out there that one can plug in numbers to get hp numbers but if you want a number that is even remotely close, you are going to have to know alot of variables to put into the calculation. displacement, stroke, cam size, fuel, exhaust, valve size, cc sizing, lions and tigers and bears, OH MY.
