Someone Sitting Shotgun

I know that weight matters but how much could an extra person determine the outcome of a race?

it would matter a lot if you were driving a civic. also, how much does that guy weigh? 200lbs?

so pretty much, dont race with a fat guy in ur passenger seat , unless ur like racing a lawn mower or something

we actually did a test. we have a buddy with an automatic v6 camaro, so we took it to the track and i ran it a few times (thing is a DOG) to get some base times, then we loaded my buddy, all 160 lbs of him, in the passenger seat and ran a few more times.

came out about a 1 tenth slower on the average

generally

every +100lbs = +.1 in quarter mile

Isn't it dependant on how much torque your car has?

Well, it involves a lot of factors. Thats why i said "generally"
