The soft-loc ran a best of 10.709 @ 126 and the clutch tamers best is a 10.98 @ 122 on the 9x26 slicks but the clutch tamer is being run with the heavy flywheel and clutch, so in fairness I am not comparing apples to apples. The last time at the track which was in late spring I put on a set of 9x28 stiff sidewall slicks and the car fell off a .15 and two more miles an hour, 60's were 1.58 to 1.62 that day(got better as the slicks broke in). Car ran kind of flat that day and ever since. Found out why last week the second diaries in the carb were bleeding down, needed a refresh. That what happens when you let them sit to long between uses.
