Weight savings to HP gain ratio?

[Tri-ZNate]

Anyone know it? I was trying to think of it tonight and for some reason I want to say every 1lb you shave off is 1/4 more HP. Anyone know it?

I believe It's 1 hp gain per 100lbs lost. Not for sure on that, but I recall reading that In a snowmobile clutch & gearing book. There Is probly alot of different variables to add Into the final figure's anyway.

[pickleweasel_00]

so is it really gaining horsepower, or just freeing up otherwise used horsepower. Guess that's the same thing, huh?

It is 100lbs loss = the equivalent of 1 hp gain I think that is right. If I'm wrong someone tell me because I have been going by that for years.

thanks guys, i didnt think it was such a drastic percentage

[atctim]

wouldn't this equation have to do with vehicle weight percentages.

Loosing 50 pounds off a pick-up truck VS loosing 50 pounds off a 250R would be significantly different.

I was told on snowmobiles it was every 9 or 18 pounds lost gives 1 more horsepower. Cant remember for sure, but could ask again.
100lbs to 1hp seems a little heavy. If you've ever ridden with a passenger, like a little brother that weighs under 100lbs, you definately notice a drastic loss, and I know its more than 1 horse.

On cars is 7lbs is = to 1hp

On cars is 7lbs is = to 1hp

I've also read somewhere that 7lbs = 1hp

Like the article says if you can remove 40lbs from the machine then you would notice the gain. I bet shaving 20 alone would make a noticeable difference.
