60' stinks.


I really don't think your 60' time is all that bad. In fact, I think it's great that you can 60' those times all day long without suffering traction problems like some of us others do. So you might consider it a compromise in favor of a more repeatable car.
Also, using those handy little formulas that estimate HP based on your ET and MPH, here's some results based on a 3300# race weight:
Mackey's old combo
12.46 -> est. HP based on ET: 337
108.9 -> est. HP based on MPH: 333
Pretty good, you're car was very efficient and ET'd better than your available HP.
Mackey's new combo
11.58 -> est. HP based on ET: 420
117.4 -> est. HP based on MPH: 416
Again pretty darn good, very efficient use of available HP.
Sanity check using Panuzzo's numbers (that's funny sanity and Panuzzo in the same sentence ;) ):
12.48 -> est. HP based on ET: 335
108.9 -> est. HP based on MPH: 332.
Again, great numbers and similar performance to Mackey.
John I am not trying to dissuade you, but am trying to point out that you might better off than you think. We all want to go faster, but maybe you should consider the traction that you ALWAYS have to be more positive than a slightly better 60'
