How do you figure this out.????

Pistol Pete · 05-23-2011, 04:12 PM

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.

Andrew Hill · 05-23-2011, 04:18 PM

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.

Car B 110 mph

Car A 100 mph

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

MOV X 1.47 X Speed of who crossed last

.0078X1.47X100=1.1466 feet

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?

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!

Others have pretty well covered the theory here.
