A old railroad engineer I used to work with once told me. A steam engine can start a load it can not pull but a diesel engine can pull a load it can not start. The steam engine has more torque but at lower revs but as it revs its power falls off. The diesel (when compaired to the steam) has less torque at lower revs but more power at higher revs.

In a motorcycle a Vfour makes a great engine cause it has both low end power and high end power. Its a great compromise. That is why I wish the new Aprilia was not so darn expensive.

Sorry, what I quoted was Extreme Pro Stock.

All we are saying is that torque is a measurable, quatifiable force, and horsepower is not. It is a calculation.

I understand that. Only reason I posted was because someone claimed that that torque is all you need for racing.

Torque is also a calculation thats the reason its express as pound-feet per second or newton-meters per second.

Its not pounds or newtons seting on a scale its force over distance during a set amount of time.

Horse power just takes that same force and compairs it to RPM.

No matter how you express the work being done they are both just units of measure and they measure work being done.

Torque

Horsepower

Which is faster?(hint, it is the one that weighs almost 200lbs more)

the one w/ APOC or Tmall riding it!

Only in a straight line and with more than twice the motor. I bet if you take off 2 plug wires to make the CCs almost equal the R6 would kick its ass in a straight line too.

Oh and its the one that has more HP too.

Compare a SV650 to a 600 and see which bike is faster its not the one with the most torque. The 600 makes about 40 and the SV650 about 45 and yet we would all agree the 600 will smoke it in a straight line and in the corners. They are near the same weight and displacement.

Gearing and the ability to rev will help it go faster, not horsepower.

The torque turns the transmission, the transmission multiplys the torque(not the HP) at a certain RPM and this creates speed.

BTW, I didn't know we were putting engine restrictions on, after all, Homeslice suggested putting a big diesel in an F1 car. So my Busa(torque) and R6 comparo are still relevant. One makes big torque and one makes lots of horsepower through revs. Which is faster?

BTW, you can even substitute the R1 for the R6, and the results will be the same, even though the R1 has HP close to the busa and a lot less weight.
