Default weight vs 1/4 time

does anyone have a ratio on weight reduction vs 1/4 time reduction??
(for example if you take 34 lbs out of your car you will go .xx faster)

is there a thread on this anywhere??

.

100 lbs per .10 is usually very close on slow cars. Less ET gain as you get quicker & quicker.

Also depends where you take off the weight, anything that rotates will net you more gain than something that is just bolted or part of the car.

Wheels, brakes, rotating parts of the engine and drive train will net you bigger gains than light weight batteries and k-members and stuff like that.
