"Power
to weight ratio"
refers to the ratio of the horsepower
as compared to the weight of a given vehicle. This, and a few other
very important factors such as traction, power curve, and final drive ratio
are directly related the the vehicle's acceleration ability.
For comparison purposes, the
design proposed by myself has a PWR of .50.
A Boss Hoss tm with the 345 hp 350 cid engine
has a P:WR of around *.30. The average "crotch rocket" will be around
.36, and a stock Harley Davidsontm would be close
to .13, or about the same as the last generation Corvette
tm. |
*Due to the fact that the older
BH has no transmission, the .5 figure would be a little "optomistic".
This is due to the fact that the rated 345 horsepower is only avalible
within a limited RPM range, and the single 1:1 drive ratio would only
allow a practical .5 P:WR over an approximate 15 - 20 MPH range
of the bikes total speed potential. |
