I ran a 9.1 at the track tonight, but it is only a 1/8. I was wondering if anyone out there has run a 1/8 and 1/4and wondering what the 9.1 at the 1/8 would be about at the 1/4 mile. Any guesses anyone?

 

14.2-14.3 somewhere around there

 

X your 8th mile et by 1.56 and you get 14.196 works really well for me..

 

anyone else have any guesses. I was there and saw a couple ss's . One did a 9.4, andother 9.0 and another ran a 9.0.

 

I agree, those are both good guesses. Looking back at a few of my time slips 14.2-14.3 seems about right.

 

Based on studying a large number of timeslips, for cars in the 9.0 - 15.0 1/4-mile range, the factor noted above - 1.56 - is surprisingly reliable. You can also convert 1/8-mile MPH to approx. 1/4-mile MPH by multiplying by 1.25

 

oh it was at 78 mph
