you cant use those formulas. theres no real formula on the net that will work. they dont adjust for 60' time and mph. they may work in some instances if your car is within their parameters but wont work for a wide range, say 1.7's-2.5's 60's.

I made one a year ago in my statistics class though that did work it was a complex formula but was usually within about .05ish. if you could graph it it has a curving slope. If I could find it ill post it but i doubt i will ever find it. I had a whole bunch of formulas, for both auto's and sticks. the only one i remember is the MPH conversion, the avg car will run .79485% of their 1/4 mi MPH in the 1/8. so your 85.5 would have been 107.6 or so.
