Here's another challenge,

What is the brake mean effective pressure of a 2009 spec F1 engine at 18000rpm assuming 760bhp output? :scratch:

That was the kind of nonsense we used to do for fun at Uni (not sad at all:rolleyes:) but that was 20 years ago and the formulas don't spring to mind like they used to....
