The car feels really strong! It feels good to be able to drive it hard and not worry about the a/f ratio etc.  I picked the car up around 5pm, then loaded up and drove to the track around 6pm. haha. Since it was the last test&tune night of the season, the dragstrip was PACKED! I was only able to get two runs in, both times first gear traction was slim to none. My first run was a 12.79 @ (mph unknown, the lady lost my timeslip).My second run timeslip (I'm in the left lane #407):<a href="http://s444.photobucket.com/user/Mustang1619/media/Mobile%20Uploads/20131029_104809_zps597cbf24.jpg.html" target="_blank"><img src="http://i444.photobucket.com/albums/qq163/Mustang1619/Mobile%20Uploads/20131029_104809_zps597cbf24.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></a>As you may be able from the slip, I still had traction issues in first gear (2.09 60' time is no bueno), but that's probably due to my 30 series sidewall, even with them aired down to 20psi..The 115mph makes me think that there is a lot better e.t. in the car (I have seen cars run 11.90s with that mph). There were a lot of things I would have liked to do to it before the race, but I was so rushed on time and wasn't even sure if it would be ready for the track, so I didn't have a lot of time to prepare. I would have liked to:  Unhook the front swaybar, adjust my front struts to the 'loosest' setting, and get some actual slicks.I had to shift into 5th gear both passes, so perhaps the combo of 4.10 gears, centrifugal blower, and 25.5" tall tire is screwing me at the end of the quarter mile. As low as my car is in the rear, I have a feeling if I want to stay in 4th through the traps, I will have to get a pair of stock rear springs, and some 26" or 28" tall rear slicks (preferably on 15" wheels). Unfortunately now, after that second pass, the car has a nasty vibration when accelerating between 2,000-2,700rpm, regardless of the gear. I need to get it up on jackstands and figure out whats wrong. I suspect there is a bushing that took some abuse, but I'm not sure.I hope to figure out the minor issues with the car soon, and continue driving it until we see snow in the forecast, then let it hibernate and get ready for next year!</blockquote>
