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!!!!
