Times conversion from 1/8 to 1/4 mile.
« on: July 06, 2008, 08:59:56 AM »
                       
           
1/8-MILE TO 1/4-MILE CONVERSION TABLE   
           
                       
           
The following table can be used to estimate what your car would run in the quarter-mile based on your 1/8-mile elapsed time. This table is useful for those of you who run on an 1/8-mile track and would like to know what this time equates to in the 1/4-mile. NOTE: Please keep in mind that this table is only an estimate of what your 1/4-mile time would be. Different cars with different modifications, such as different rear end gears, will react differently. Your car may be a little quicker than this table shows, or a little slower. Again, this table is not exact, but simply a tool for estimating.

adding 4 seconds is gonna depend on what your 1/8th mile pass was. and I think mph has some play too. I ran 5.03 at 143 in the 1/8th and let off just past the 1/8th, it still ran 8.24 in the 1/4.

 What if your NOS car went a 5.00@ 140mph while the turbo car in the other lane went a 5.00 @ 160mph  in the 1/8... no way are they going to be even close in the 1/4.   its all just guessing.
