Just for fun and I can't remember the numbers, but what does 1 pound of weight equal in horsepower? I know this is just a close guess but I can't find my old notes on the subject.
-
There is not a formula to convert pounds to horsepower. A pound is a force. Horsepower is a unit of power.
Power = Force x Distance / Time
A pound is just a unit of force.

I think a good question is how many pounds does 1 HP have to move. If you have a 3000 lb car with 500 HP each HP is moving 6 LBS. If you have a 600 lb motorcycle with 200 HP each HP is only moving 3 LBS. That's why a 200 HP motorcycle is faster than a 500 HP car.

+1 POWER to WEIGHT ratio

It's not a matter of how much weight (1 lb or whatever) 1 HP can move.
Virtually there's no limit....
It's just a matter of "how long it will take" to move it! ;)
With a proper gear or lever you can move anything: the more power you have the faster you do it! :D
(If I'm not mistaken... ::))

A formula I heard long before I discovered the net is losing seven pounds is roughly equal to a 1 HP gain. How true it is? No idea, but weight loss is a key to any race setup, from titanium to extra holes. Less mass means more efficient movement/less required power to move it.

Depends on where you lose the weight plus how heavy the vehicle is. 7 pounds on an 80k lbs semi tractor wouldn't mean jack but it means a lot on a 440lb sportbike.
Weight reduction on a rotating member, (wheels, transmission, engine,) is much more effective than on a static member. Also the faster the component rotates the more effective the weight reduction will be. I.E. 1 lb off the flywheel will be more effective than 1 lb taken off the wheels, which is more effective than 1lb taken off by your fancy fender eliminator kit ect.

That's it SoP. Back in the day of my track days I remember carbon fiber, titanium, holes, don't need this/that made us faster. When you have "X" amount of HP and depending on the weight it has to move determines how fast one could go. Yes, power to rate ratio. Again just for fun in theory I battle with myself on "should I get that exhaust system to gain 10 HP, or should I just loose that weight the doctor said I should to equal that same HP number?"
-
If I remember correctly, the weight/power issue had a lot more to do with acceleration that top speed. Losing a few lbs would have a big effect on accelerating to top speed, but make very little difference to the actual top speed.

So what you guys are saying is if I lose weight I will be faster?? (http://i1200.photobucket.com/albums/bb336/jaywilcox/smiley_dunno.gif)

With the exhaust you will gain that 10 hp and also lose a few pounds. It's kind of a win win all the way around so why not do both?

That's just water retension from too much salt. So cut back on your salt intake and you'll be all good! :rotflmao: :chugbeer:

This all sounds like math to me so I'll just stare out the window until class is over. The dude with the Shiner on his belly needs to get to the hospital and have that tumor removed. Good God no way Shiner wants him as a spokesman.
