someone posted a chart a while back showing 1/4 mile times for both of these. it was like:

3000 lbs, 300 hp = 13.0
2900 lbs, 300 hp = 12.8
2800 lbs, 300 hp = 12.6

3000 lbs, 300 hp = 13.0
3000 lbs, 310 hp = 12.8
3000 lbs, 320 hp = 12.7

anyone have the link? thanks

 

A hundred pounds shaves about a tenth off your quarter mile time.

 

that's just an estimate. as ur times go down weight reduction becomes more beneficial though. in other words when u get down into the 10's dropping 100 pounds will give u a better ET than adding 10 hp

 

It takes dropping 212lbs to gain 1/10th in the 1/4.

 

+1 million

 

Is that serious?

It has a lot to do with the car too.

Weight reduction will help out more on a torqueless honda than a mustang

200 lbs is probably more like .3

evo 9 vs evo 10 with like the same power but a 300 lb weight differance is like .6-.7 in the 1/4

 

those numbers seem slow, unless they are talking about HP at the crank. My race weight on my bullitts is over 3400lbs and at 320rwhp I ran a 12.4-.5 not really "driving" the car. But Ox is probably right about 200# = .1 in the 1/4.

 

like that guy said... sort of, its not just losing the weight, its where you lose it from, weight transfer etc etc, maybe if its just overall weight taken evenly its 212lbs/.1sec.

 

there is also a big difference between removing 50#'s in seats and 50#'s in wheels.

 

so ( and im not argueing, just learning) if the 4000lb charger/challenger loses 200 lbs of dead ( non rolling mass) it will only gain .1 in the 1/4 mile?

what about if it got a set of big n littles instead of those 20's
