1/8 mile to 1/4 conversion

Could any tell me what a 1/8 mile time of 7.09 sec at 97.17 mph run would translate to a 1/4 mile run. The 60' was 1.634. Thanks Tim

I dug up a timeslip that can give you some idea. I'm the slower car on the left.

60 foot time was not as good, but 1/8th MPH was a little higher.

I'd say a 1/4 mile would be very low elevens.

There's qiuite a few variables that make it hard to accurately predict.

Hope this is helpful.

Thanks for reply and timeslip. I was expecting hihh tens around 130mph. What car were you running? How much rwhp. At the time I was at 570rwhp. Tim

I have 550 rwhp

My time slip could possibly have netted a very high ten, if I had your 60 foot time. I predicted low elevens because of your 97 mph speed.

However I did have another run (at another track) that had a 7 flat at 100 mph for the 1/8th, yet I still didn't crack the ten second barrier. My best trap speed has been 128 mph.

I make very consistent runs, but I'm sure a better driver (gear puller) could do tens with my car. One of my great excuses is "that I didn't hook up".

Get over to a Quarter Mile Track and best of luck!!!!

Also, here's a timeslip out of Drag Times Database that supports your prediction.

It all boils down to the track and driver.

10.9 second quarter

The general rule of thumb is to multiply your 1/8 mile time by 1.5 to find your 1/4 mile time.
