i have always heard this if you have a passenger in your car for every 100lbs he is, that will cost you 1 car length for each 100 lbs.

is this true.... anyone know?

Im not sure about that but i heard for every 100 lb its like .1 sec off your 1/4 time...

Ditto on the .1 off of your quarter mile time. That's about all I've ever gained or seen anyone gain when dropping weight, it's not precise but it's a good reference.

...and the distance in .1 sec would depend on how fast you were going.

but also... think how much more sluggish your car feels w/ a 200lb friends of yours in it.

If you take a 3650# car that runs 100MPH, and add 100# to it, you will add 0.12-seconds to the ET. At 100MPH, that is 17.6-feet. A 4th Gen is about 16.3-ft long, so it looks like a good "rule-of-thumb".

If the same car was pulling 120MPH trap speeds, the length difference becomes 21.1-ft, so its more like 1.3 car lengths.

well that is good to know..... i had a feeling it was around that from what i have heard.


thanks for the input
