If I ran my car with 3.23 gears and got a time and then ran it with 3.92 gears the car would go faster. Did this change the engine horsepower.? No, this changed the RWHP.
If this is not true please explain it to me  |
A steeper gear is a torque multiplier AND a speed reducer. They cancel out to give the same HP.
HP = Torque x RPM / 5252
Using the above numbers, the wheel torque is increased by 3.92/3.23, but the wheel speed is reduced by 3.23/3.92. HP is unchanged.
Hope this helps.
