The figure that converts between lbft and bhp against rpm mate.
Ah, so it's just a number in an equation then and doesnt actually relate to 5252 rpm or anything like that.
Well, yes and no.
It IS just a number in an equation, but it implictly defines the cross over the point for torque and horsepower in lbft and BHP.
If you quote in NM and PS you get a different number, and hence a different crossover point.
5252 is the point in the RPM range when ALL engines will have the same power and torque if they are quoted in lbft and bhp
