Its definitely not the 1:1 ratio, because I took off 58 lbs from my raptor and its not that its 118hp bike now but it did make a big difference.

what about when an engine alone sits on a dyno, it puts out a certain HP.. But when it gets attached to a car and then dyno'd that HP decreases. Do you think the weight difference plays a part?

If I thought I could gain 1hp for every pound I shaved off my Warrior I'd be gettin out the torch pretty quick!! [img]i/expressions/face-icon-small-happy.gif[/img]
95Wolverine got it right .. it only affects the "apparent" horsepower ... that's why weight savings are so important .. power/weight ratio is a big factor in the performance of any machine.

Think of it this way. By taking the weight of a vehicle and its quarter mile time you can work an equation and get a measure of HP. By lowering a vehicles weight it will be faster and if you calculate its hp using its old wieght it will come out to have more hp. Ofcourse you have to change the equation since it now weighs less but compared to how it was before its like you gained hp. There is really no correlation between weight of the bike and hp, its just to give a tangible speed representation to how much losing a certain amount of weight would help "If we could shave 70lbs off of this bike it would be the same as gaining ~10hp!".

That's the difference between flywheel horsepower and rear wheel horsepower, where there is parasitic loss through the drivetrain.

I asked this question awhile back and all I heard was to many variables. [img]i/expressions/face-icon-small-disgusted.gif[/img] Now everyone is all over it this time. [img]i/expressions/face-icon-small-sad.gif[/img] You are leaving out torque [img]i/expressions/face-icon-small-confused.gif[/img] I see how it is.

Lets make this simple. Strap a 5hp motor to an anvil with wheels, then strap it to a 2x4 with wheels. Which one is faster? the 2x4. They both have the same hp. The anvil woluld need like 20hp to keep up so if you shaved the anvil down to a little bar that weighed the same as the 2x4 you could say the anvil had done the same thing as gained 15 hp.

Cool, so all I have to do is shave my anvil (Warrior) down to a sliver and the apparent gain would have me whoopin 450's [img]i/expressions/face-icon-small-happy.gif[/img]

weight loss= more speed, not more horsepower
