Torque is what moves you...HP is what gets you there....

it should help to understand that torque means nothing.

Power (hp)=torque(lbf.ft) x 2Pi x RPM/33000=Torque x RPM/5255

I'll race you with both my plugs hooked up.

Horsepower is what i consider to mean nothing. Horsepower basically is nothing but work performed over time. Take a 1cc engine producing .0001 f/lb torque and spin it to 10,000,000rpm and it will produce the same hp as a 10,000cc engine producing 1000f/lbs of torque at 1 rpm. The 1cc engine wouldnt be able to move anything beyond its own weight without REDICULOUS gearing.. while the 10,000cc will haul nearly anything without noticing... but VERY VERY slowly.

Interesting... but why do dyno's take torque and rpm to calculate HP.... ?

2 engines with same HP will move anything the same.
Formula HP=Torque x RPM/5252 is a high school knowledge. I was studying that when I was 13. You just need to read text book for high school to understand that.
Old farts like me usually don't remember physics.

If you stick 5 feet long rod in rear wheel and try to spin wheel with force of 20 lb. you will create 100 lb.ft torque (20 x 5). How fast will you move your bike considering 100 is pretty good torque?
Get physics text book, guys.
