from
this it would be something like
Code:
1/2 * 700 / 32 * (5280 / 3600)^2 * (VSS^2 - VSSi^2) / T / 550
where the 700 is a guess at bike+rider weight, VSS and VSSi are final and initial speeds, and T is the time to go from VSSi to VSS.
Trying this for a rocket III using 900 lbs for weight and the reputed 3 second 0 to 60 time got me a scarily accurate 142 hp. Probably a coincidence but it shows it's in the ballpark and it's certainly sensitive to the right variables. At best though, it's going to give you some kind of average hp figure. Nothing like the precision of a dyno.
Anybody got an acceleration time for an america?
