Every 100lbs=100mS increase in 1/4 mile time?

This is according to a dude that lives two doors down in the dorms. Even though this is non-sense in physics perspective I don't know how much sense it makes among racers.

Is this a somewhat meaningful statement or pure BS?

Definitely true. A five hundred pound man would beat a 100 lb man in a 1/4 mile race by at least 400ms.

beaten maybe, but the fat man will not win.

edit: unless he has an SiR sticker on

Well, since acceleration=force/mass*weight+volume-area, yes, it is true.

When someone blanketly say "for every 100lbs of added weight, you add 100mS to your quarter mile time" does not account for vehicle mass among other things.

It's called a joke?

Could be, but I don't know jack about the "real world" quarter mile performance. It could very well be the truth, misinformation or plain old joke.

for every 100 lbs of vehicle weight removed you will lose 1/10 sec in the quarter mile.

so if I toss the dead chick out of my trunk i'll save .04 seconds? (I tried to starve her to death, but she wouldn't die so, i slapped her to death. it took a while)

It's generally fairly close when you're talking about cars that weigh roughly 2500-3500lbs and run 12-16 seconds in the 1/4 mile.

if she was in the car when you did your weigh-in and run down the quarter, then yes.

That's ridiculous. It would mean that 1000lbs only adds 1 second, in every car. It depends on the weight of the car to begin with.

That is correct. We are removing, or adding as the case may be, weight. This not as dramatic as increasing HP.
