I guess stall could affect it some. But the car did go faster overall going from 5500 to 6500. When I ran the 8.77 with a 1.27 60 ft I was running radial M/T drag slicks, 14x33 at 34 lbs each. The tires I have now are 39.2 each. Best I have been able to post with the big tires is 1.259 with an 8.86 ET.

8..603 156 mph best, 2905 lbs 549, indy 572-13, alky
