The electric to be the same, as the gas needs to be 10 hp. The 7.5 hp can not keep up with the 20 hp gas now. The reason for this is the gas engine produces a power stroke every two revs. The electric produces power every rev of the motor. It is plain and simple as that. Allis Chalmers WD has 35hp, the WD45 has 45hp.
