I mean most 1000s redline around 13,000 so why are they faster than 600s that redline at your 17,000? I seriously don't get it. Basically, a 600 that redlined at 20,000 will beat a 'busa at the dragstrip because of it's higher rpms? Huh?

Honestly, on the track they would be pretty similar because you're using the work of the engine to achieve acceleration.

Now, on the street where you're likely to be in the wrong gear, the higher tq would make a world of difference.

Keep in mind though, if the hp is equal the engine would be moving the same amount of air and fuel barring slight variations such as compression and frictional losses. As for your busa analogy, the tq and length of the busa would get it off the line faster.

Keep in mind with the rolling start that advantage is taken away from the buell.

The problem with all engines is piston velocity and the cost to build them to withstand those stresses.


Talk more later. Typing on a blackberry sucks..
