I ran a best of 13.03 @ 111.6 with a 2.1 60' this weekend. I only have a TSP lid, K&N filter and breather, FRA, TB Coolant Bypass, loudmouth, slp Y-pipe and a GMS/Diablo Predator. Now I know the time seems about right for an 01 with these mods, but that mph is really high. It wasn't a freak run because I was running over 110 each run of the night and consistent 13.1 and 13.2's (2.2 60's) until I finally broke into the 13.0 mark.

Before the predator, loudmouth, and y pipe, my best was a 13.5 @ 108, and I dyno'd 306hp and 329ft/lbs. Most cars I see going 111 are running mid 12's, and even 108 is pretty high for a mid 13 second time. So what can everyone make of this?

 

Traction problems?

That MPH should be good for a 12-second slips.

 

Actually, that was bogging a little off the line. I know I can launch a little harder, but i'm still trying to learn that point between bogging and going up in smoke.

 

an M6 car is capable of hitting that speed on a high 12 low 13 second pass. My friends M6 TA went 12.85 at 113 with a lid and loudmouth.

 

Does the weather seem a little better: drier and cooler?

Weather makes a pretty big difference, going from 80 degree air to 60 degree air could give you 1-1.5mph.

 

M6 or A4?

 

It was a bit cooler, but only about 10 degrees. It is a M6 car as well.
