Doing the math figuring 52 mph at the 60 ft clocks (average) I come up with .1224 lost time.

That is about the same as I come up with if I assume 52 mph and 111" between the front and rear tire trip points.

But I think closer to 55 mph and with a 108" wheel base, and tire diameters of 26/31 (~105.5" between trip points):
55 mi/hr x 5280 ft/mi /3600 sec/hr x 12in/ft = 968 in/sec
For 105.5", that is about 105.5/968=0.109 sec
So the rear tire 1.37 might be about 1.26 with the fronts.

I might not have this 100%, but that is my estimate. The experience with my car is about 0.10 sec difference.
55 mi/hr x 5280 ft/mi /3600 sec/hr x 12 in/ft = 968 in/sec (again)
And my car is 111 -(32/2-26/2)=108.0" between trip points, (not exact need equation of a circle at beam height)
So... 108.0/968 = 0.11 sec and I have seen about 0.10 on the same day.


ouch... my head hurts
