Yeah, horse is the actual power the engine puts out. It has no correspondence with weight at all. Agreed a power to weight ratio will increase quickness. But not horsepower. And as everyone stated above 8lbs. is foolish to mess with. This thread was dead after the first answer. Don't argue on this one. I would hate to see some of these guys get ahold of this thread on here.

"Unsprung" weight is the wheels, axle, etc.--I.e. mass that is not supported by a spring; "sprung" weight is the body, tranny, engine. The distinction you state is betweenfixed and rotational mass--nonetheless, the "rules of thumb" youprovide are are entirely valid...[/align][/align]Minimising unsprung weight improves handling as the springs and shocks have less mass to control; this improves the compliance of the suspension--allowing the tires to maintain better and more constant contact with the roadway.[/align]

8 lbs is 8 lbs. If it's not serving a purpose, remove it. DUH. Why do guys put on fibergalss fenders then if they only save 5-10 lbs each? Yes, 8 lbs is significant. Not huge, but significant to most performance enthusiasts. The location of this 8lb weight is unfortunately notin a place to gain the most benefit, but it's still dead weight.

.1 improvement for every 10hp or 100lbsis the rule of thumb. 226 lbs per .1? Nonsense.

That would be stupid for every 10pounds is 1hp. (from what i hear) This is only 8 pounds u say then u wouldnt even gain 1hp out of this. So no dont that would be pointless
So if I loose 60lbs of body fat, my car will gain 6hp?? Unlikely!

You don't gain any hp from removing weight. For every 226 lbs removed = .1 off your time in the 1/4 mile.
[/align][/align]You could remove 1000 pounds and not gain any horsepower. As for removing 8 lbs. having no effect--nonsense... It may be a very small effect and negligible effect, however it has to have some effect. It is also unsprung weight. Certainly not a giant component of the total unsprung weight of a Ford 8.8" rear-end, nonetheless reducing unsprung weight is always good. [/align][/align]I agree that removing it will make make no discernible difference in anything, however it also does no harm; much like removing the air silencer or slapping in a K&N drop-in filter. There's a whole lot of crap people do modding their cars that provides no measurable performance gain by itself, or for that matter ever--nonetheless we all do it, have fun doing it, and I plan to keep on doing it 'til the day I drop...[/align][/align]

Have you ever heard of power to weight ratio. You remove a 1000 pounds i assure you. You will be gaining hp. Not of of 8 pounds but a 1000...yeah you will
hmmm.... how could you say you will gain hp from removing weight? I don't care how much weight you take off it will not increase your hp. however it will cut your time off and make your car accelerates a little faster.

Dont be ignorant yes if u lose weight ur cars time will be faster. Of course your engine isnt gaining hp for every 10 lbs don't take so litteral that is just a way they have determined or caculated the decress of time on ur pass to the amont of weight taken off so yes 10 pounds does affect it ur cars time and 60 pounds would help a good bit in ur times.

I believe he knows that... but thats not what you said the first time. You said that taking weight out of the car gives you HP and it doesn't. I can't put my car on a dyno and get 400rwhp and gut the whole interior and put it back on the dyno and make 425rwhp... Thats all he was saying. Lets not get too difficult here guys.
