Hmmmm...And you believe this to be true?

Twisting force is just that. How many times per minute is power. Half the force means that you need to do twice the RPM to achieve the same result.

Unfortunately there is friction between the tyres and the road and you cannot do double the RPMs if the vehicle is doing the same speed, unless you break traction or have an extra 2:1 gear ratio.

This is fine if you want to do twice the RPM through the gears which you are correct, but if the two engines are of the same capacity then your swept volume per minute has doubled.

I will again ask everyone on the way home from work to drive your vehicle in a selected gear (say 2nd) and bring the revs up to your engine's peak power and then give it full throttle and feel the acceleration. Then redo the test at peak torque or even half the revs and feel the acceleration. IT WILL BE GREATER. Yes the vehicle will be going a greater speed at the peak power which means more work is being done, but we are talking acceleration here and the power you will use at the better acceleration will be much lower than your peak power.

Again, Hightower99...Shane is waiting for your contact. Please talk to Shane before your next post.
