It takes a lot more power to go faster.  If it is assumed that the power required goes up with the cube of the speed (square law for air resistance and linear for rolling resistance), then if 9 bhp is needed to reach 40mph, about 12.5 bhp is required for 45mph, and 17 bhp for 50mph.  As my Ruby seems happy to do a maximum of about 45mph, this might suggest it is currently putting out about 12.5 bhp rather than the 17 bhp Austin originally intended?
