Right..simple one(!?!) this..
If you take two identical vehicles (say car or bike). You give vehicle 2 exactly twice the bhp, twice the torque and twice the weight. Vehicle 2 has identical engine characteristic curves to vehicle 1 (e.g. peak bhp at say, 7000rpm, etc...)
Is car 2 any 'faster' with regards acceleration and top speed?
I think I know the answer, but thought I would put it out to the floor...
