BHP Calculator

How much brake horsepower (bhp) does your cars engine produce?

Where did you get the figure from?

If you got it from a dyno then its probably wheel horsepower.
If you got it from the manufacturer then its probably flywheel horsepower.

The two are very different and in racing its wheel horsepower that counts.

Use the system below to convert between the two:
