Found a link to this 1/8th mile time to 1/4 mile time converter on a Mopar site. Could be useful while the track is only running 1/8th. Seems to be pretty close for our car.

yeh but how accurate it this... some cars are faster to the 1/8 but slow down by the time they get to the 1/4 mile... some cars are the other way around... slower to the 1/8 but have crazy topend speed...... ill take a look an see how it works...

It is only a guideline, nothing more. Still, it is at least a reference. Unfortunately, it does not appear to be a spreadsheet or similar where you can see the formula they utilized.

It's not hard you get a old time slip, divid your 1/4 mile time by your 1/8 mile time to find the multipler, it should be between 1.50-1.57...Then multiply that numer by your 1/8 mile time. and that gets you your 1/4 mile time. but you need a good 1/4 mile time slip to start with. the faster the car lower the the number the slower the car higher the number.......:bowdown::bowdown:

U know u just went in a circle right?



Lol anyway ask reyrey i was talkin about multiplying your 1/8 by 1.5 to get an aproximate 1/4.

I other words get a old full 1/4 mile time slip only if you have one, and divide 1/4 mile time by the 1/8 mile time.you get a number between 1.50-1.57 then you multiply that by what ever 1/8 time you get since we not running to the 1/4 mile any more. and multiply to get your current 1/4mile time. multiplying your 1/8 by 1.5 will be wrong. 1.50 is where hi hp car run. you might 1.55-1.56 you get it.:eek::eek::eek:

but its like street said your 1/4 mile could be way different some cars exceed in there take off some make up for it in the top end...like hondas in top end and muscle cars on launch or to the 1/8th

that's why you need a full time slip to find out how fast your car is from the 1/8 to the 1/4 mile.that's why you divide 1/4 by 1/8 time.

but why would you need to convert if you had a full slip thats what i don't understand....those too times could be different don't you agree....well if it works then makes sense I guess.

say your goal is to run 10.20 you know from previous time slips your car multiplier is 1.52. you don't want the competition to know what time your running. so you test your car to the 1/8.You know you need to run 6.72 x 1.52 = 10.21 in the ball park. simple math learn that from a guy at Atlanta Drag way.
