i run 9's in an 1/8mile what do i run in a 1/4?

Those calculations are not all that corrected, because MPH isn't taken into account. I cannot find the old calculator that had the MPH in the equasion. Those equasions are based upon an average. Lets say your run a 9.2, but at near 90mph, you will probally break into the 12's, but if you ran 8.2 but at 80mph, you'll be somewhere in the 13's.
 
Is that a flat 9, mid 9, or high 9's? 60'? mph? Youll need alot more info then that, but it can range from 14-14.9 depending on mph and 60'
