Okay, got a chance to take my car back to Richmond Va today, its been like a year and a half since I got he chance again

.
Lesse, wayback then it was 5 quarts of Mobil 1, a 70mm T-body, and 3 chamber flows on stock radials and absolutely no experience driving a manual car, also back them it was with a 1/2 tank of gas. IIRC, my best run was 14.59ish
Anywhosit, this time, the only changes were a set of 275/50R15's BFG Drag Radials on a set of Convo-Pro's.
Run 1
14.37 @ 99.08 with 2.251 60 ft. time. 26 psi in the tires and 1/4 tank of gas. engine at normal operating temp. did not warm tires
Run 2
14.49 @ 97.98 with 2.268 60 ft. time. 26 psi in tires and 1/8 tank of gas. engine at normal operating temp. did not warm tires
Run 3
14.03 @ 98.81 with 2.193 60 ft time. 15 psi in tires 1/8 tank of gas. engine had cooled down to about 1/2 of normal operating temp. warmed tires in what had to have been the most pathetic burn out of the night.
What do you guys think (btw this makes about 6 or 7 runs total down the track from last fall to this fall).
was hoping to crack the 13's and 100+ tonight, but had to call it short.
By the time I make it back to the track I'm hoping to have upgraded the exhaust with an X-pipe, and new exhaust (a ding-dong smacked my car about a month ago and jacked the exhaust). I'm thinking about going with a catted X-pipe and bullet mufflers (anybody try this combo yet?) along with that Steeda cold-air pack (3/73 gears, cold-air and flashed computer) and maybe some pullies, the Steeda kit appears to eliminate the need for a timing adjuster?
Any thoughts?
warranty's out (got 31,000 on it), but I still got to finish my 91 stang before I can get serious on the 4.6 and rip into it.
