Message Does your experience document a 2x factor from 60' to ET? (i.e. .1s faster 60' --> .2s faster ET) Although I understand the math, my data doesn't I assume you guys saw my drag times? We were hoping for LOW 11s (Mark had said 10s - wow!) with my set-up. Well, after a few test runs at 16psi boost and 20psi in the MT/ETs, (116 traps with 2.0s 60's), I turned up the boost to 21psi. Here are the two runs I got in after turning up the boost. The second run was after dropping the tire pressure to 17psi.

First run_____Second run
60': 2.044_____1.820 (-.224s)
330': 5.300_____5.022 (-.278s)
660': 7.912_____7.618 (-.294s)
MPH: 94.43_____95.20 (+.77mph)
1000':10.170____9.871 (-.299s)
1/4: 12.052____11.753 (-.299s)
MPH: 120.37____120.17 (-.2mph)

Maybe on HIGH HP cars the difference is more noticeable, but this data point suggests just 1.33x (.224s * 1.33 = .299s). Any suggestions as to what I can do to better realize the better 60'? I'll have to keep experimenting with the 60's also to drop down towards those 1.6s marks. Even with a 1.6, I've calculated that my car has MAYBE an 11.3-11.4 in it, but will be hard-pressed for that 11.0 or less. On 116 octane, can I *safely* run 24psi and 23 total timing (includes the JWT +2 degrees)? Thoughts?
