Thanks! It was nice to make 11 runs and every single one was in the 12's. The absolute worst run of the night was a 12.89, but I was experimenting on the launch (from off-idle to powerbraking at higher and higher revs). Left it in "drive" all day and let the computer shift for me (6,400 rpm's) so I could focus on launching.
By the way, the best runs were done by idling at the starting line, then flooring it just after the 2nd-to-the-last amber. Flashing the converter from idle is the recommended method by the company that built my converter and they were right.

Wow, old thread. Amazing what happens when we lose 8 months of data.
Anyway, I did get to a different track (Pacific Raceways near Seattle) a month after the runs above. That was in Nov 2008. Learned from my first outing with the supercharger that 4th gear (drive) is not enough with short drag radials, so at Pacific Raceways it really helped to let it shift into 5th (overdrive).
I only got two runs in (last day of the season), but ran a pair of nearly identical ET's (12.338 and 12.345) @ a best trap speed of 111.93. 1/8 mile #'s were better than I thought: 7.9 @ 90...
I'm car #4164 in the right lane for both passes. The left lane cars (for those who are curious) were 1) a Chrysler 300 SRT-8 and 2) a 2008 Corvette ZHZ automatic Hertz rental car.


Have not been back to the track this year at all (had the supercharger lose a bearing at the beginning of the season and it was two months before it was repaired, shipped back, and reinstalled. Been too busy to go since then, but had some tuning changes done (picked up 13 rwhp and made the converter lock-up sooner) so I'm curious how that translates onto a time slip.

After adding an SLP catted X-pipe last month, I made one last trip to the track before they closed for the winter. Ran a new best of 12.145 @ 113.05 mph on a 1.797 sixty foot.
