How do you figure this out.????
 

Car A dials a 12.10, runs 12.109 .019 reaction time
Car B dials a 11.72, runs 11.73 .011 reaction time

Car B gets there first by .0078 & mov was .0078.

Thats 7 thousands, almost 8. How many inches or feet did Car B win by ?????

You need to know the MPH.

Re: How do you figure this out.????
 

Convert Car A's MPH to feet per second then multiply by the margin of victory to get the number of feet Car B won by.

Re: How do you figure this out.????
 

Car B 110 mph

Car A 100 mph

MOV equals a little more than 1 foot doing the math on those numbers....

There once was a web site where you could figure that out, but it's no longer up and running. Anything on Michael Beard's site?

MOV X 1.47 X Speed of who crossed last

.0078X1.47X100=1.1466 feet

This article explains it quite well, it's just what Steve posted.
Hi Steve, how's things.

Re: How do you figure this out.????
 

I've been discussing this with a few people lately and we've come to the conclusion that this formula gives you a mostly accurate number as long as both driver's keep their foot on the throttle all the way through the finish line. As soon as one of the driver's (mainly the second to cross...but both can effect a change) slam the brakes or change the rate of speed as they are crossing the finish it becomes much more of an approximation than an exact science.

The problem is most of our cars are consistantly accelerating all the way through the finishline stripe so the rate of speed isn't constant at any point on the track. Which means if that formula says it was a 5 foot stripe the second car was actually traveling at a slower rate of speed at the exact moment the first car crossed the finishline, than it was when it actually crossed the finishline so it was a little more than 5 feet (even if both kept their foot on the floor). Maybe too small to care about but it all depends on the speed and the rate of acceleration the car is still at.

Thank you Steve, George & Brad for your figures on inches & feet i lost by.

One day i'll be on the other end of those .0078 MOV. lol

Pete,
That was a great race we had 1st rd at Atco. I told ya that package will win you a ton of rounds. I just a bit lucky and didn't hit the brakes any sooner then what I did or I would have been .007 behind you! See you this weekend.

Re: How do you figure this out.????
 

Steve
Yes, that was a great race & yeah, i hope i can continue those pkg's.

I'm skipping the Grove, see you @ E-town.

My Crew Chief Pro 7.1 tells me you where 2 feet behind

Re: How do you figure this out.????
 

Nah, always did it longhand. If I recall, it was like 1.8" per .001 at 115 mph, so I typically just figure 2" per .001 just for guestimation purposes. Faster you go, the more distance covered per time, and vice versa (ie., be VERY impressed with Jr. Dragsters taking .00x stripe!) Had a fun one at the Spring Fling (1000') this weekend... DF/S Turismo vs a Top Sportsman car. He carried 83 mph on me! :eek:

Others have pretty well covered the theory here.
