Easy to remember. Two pies 'n' tea.

So:-
2 x pi x RPM x torque(lb.ft)

33,000

Result is approx 112 bhp.


OK, now if it's generating 200BHP at 5000RPM, what's the torque? (I'd
have stuck with kW, about 84, with fewer conversions but that's not
important)


Think you may need to get your maths books out and revise. ;-)
