How many car lengths equal a second, while racing.

 

Theirs no set number, faster trap speeds make car lengths not worth as much time. BUt, I suppose if your trapping 95-100 mph then a car length is about a tenth.

 

We always use the 8 cars = 1 second when setting up...um...after hours acceleration contests..

 

yeah.. i always thought 1 car length = 1 tenth.

 

i always heard a car-length is 3 tenths

 

can't be............. imagine 3 cars parked bumper to bumper. and then fly by at 100, it will probably be close to 5 tenths of a second from front to back. 1 tenth sounded good, but it just seems too short of a time. but hey at 100 mph everything is a blur

 

100 mph is 146.7 feet/sec. So, the 1 car length = 1/10sec is a good rule of thumb.

depends on trap speed.
