Stock mustang track notes

[budgetmaster]

I have been heading to the track a lot lately for the past few months and have tested the following parts.

Installed 1 5/8 hedman equal length headers best time was 13.57 at 101.5mph.

Installed stock headers back on- best time was 13.41 at 102.7. Also much better light throttle response.

Played with a C&L 73mm maf and gained nothing over stock maf-tried numerous timing settings, etc.

Car runs best w/ 87 octane at 14deg. timing at 36# fuel pressure

Had opportunity to run all the different combos during good and bad air days. Noticed car picks up more than 3 tenths in cooler, dry air. Humidity seems to have more affect than temp.

Car wt. is 3150lbs. w/ driver running on mcreary G-60's at 12psi.
60 fts- 1.85-1.95

Just looking for comments, or suggestions, experiences.
