Re: General wieght reduction question
The gernal saying is every 100lbs lost = .100 in the 1/4

Edit
it depends on what type of mass is removed. Less rotational mass will feel as if youve gained more power, than stationary mass. I believe it goes like this:
100lbs stationary mass removed= .1 second gain in 1/4 mile
10lbs rotational mass removed=.1 second gain in 1/4 mile
100lbs stationary mass removed= .1 second gain in 1/4 mile
10lbs rotational mass removed=.1 second gain in 1/4 mile

Re: General wieght reduction question
okay so youre not actually gaining horsepower your just gaining an advatage of power to weight ratio, the motor does not change power output but changes the power to weight ragtio causing the vehicle to be faster taking time off of your track time or the time it takes to get from 0-60

Re: General wieght reduction question
wow..you suprise me dory!. you cant just add horsepower by taking stuff out your car.
do you know what Power to weight ratio is.
so if you have 2200 lb vehicle with 200hp
and if you have an 1800lb vehicle with the same hp..
which would more likely be more quicker, meaning acceleration...the one with the lighter weight because of less force has to be applied to the vehicle. simple science there buddy duh!!
and if you cant understand that, here it is in Lamens(sp) terms.
tell me this, which one is going to win a 100 meter racing?
a person with a fat woman on his back
or the person without one and they both have the same agility! HMMM????
and no horsepower is not the answer.

Yeah. 100 lbs. = .1 seconds in the 1/4 mile. It's that simple. Force, mass (sprung and unsprung), acceleration, gear ratios, thermodynamics, power curves, all that can be thrown away and simplified by "100 pounds iz 20HP, lawlz." Newton was a sucker.

Re: General wieght reduction question
I hate this saying. It is not true. That .1 sec will ony appear if your car has the x hp and y weight.
If I was driving my 4500lb truck with 350hp would I gain the same amount in the 1/4 as my 1800lb car with 200hp if they both lost 100lbs?
Fuck no.

Re: General wieght reduction question
I fuckin know that the Engine doesnt gain hp,, i said it felt meain the ratio,, But i was just wonderin if there is a simple formula to figure out the weight to the rotational hp,,, Which i have gotten thanks
