how much torque and horsepower at the crank do the 01 and 03 gsxr1000's have? and is it under rated ??
i must give a f#%k or i wouldn't be asking? i already know rear wheel hp. in the future donkey if you don't know the answer don't bother to reply!!!! nice screen name geek!!!!BusaGeek@work said:
Who gives a flying F%$k. Are you going to drive on your crank any time soon? What we need is the rear wheel HP of the others, not the crank HP of the gixxer. Crank HP is a number that marketing people really like, that's why you see it in pre-release materials before a bike comes out.
it depends on how you measure the horsepower. on an inertia dyno where power is calculated from acceleration, things like rotating mass matter. on an eddy current brake dyno where the measurement is done under a constant load, it doesn't matter.Krispy said:
I personally would like to know fi there is any HP difference from going from a 530 chain to a 520 chain. Is there a rotational mass calculation for using less unspring weight (ie chain conversion or aftermarket wheels) Or does this not have any effect on the HP #?
well, one could say that you don't need such a correction, because the change in horsepower readings is a quantitative measure of how changes to rotating mass affect acceleration, and this is also reflected in the real world.Krispy said:
So, I guess my next question is, does a good dyno operator include this info, or not? Does he have access to proper adjustments factors (ie:HP# X 0.95 for a 520 conversion, or HP# X 0.91 for aftermarket wheels) to accurately measure HP for a heavily modded bike on an inertia dyno.
