* I found these results to be somewhat misleading. There was a slight improvement with the pulleys but not the 2 to 3 tenths that the times show. Runs #11-14 were run in early April (very cool air) with 1/4 tank of gas, no spare tire in the trunk and under exceptional track conditions. Runs #5-10 were made on a different day with slighlty slower 60 ft. times. Runs #1-4 are actually the most recent on the list but turned out to be the slowest because of the 100+ degree temperatures in the middle of June (very hot air).
