Went to the track yesterday for a charity event, and was able to get some t&t in before the shootout next Saturday.

Aric has been working on the street tune moving the delay way out for torque converter lock up in order to make some space between the 2-3 shift, overdrive, and tc lock not happening on top of each other while cruising around town.

He has done a great job with it, and I am happy with the way the car behaves with light throttle below 50 mph.

Now the question is, what did all these changes do to the WOT performance? I turned the keys over to Steve and Aric to data log, and make changes as they see fit.

Here are a couple video runs with Steve driving the car. Aric decided it needs to go back on the dyno this week, as Steve said he believes it started to rattle and he lifted on the last pass with 20* timing (the video against the trailblazer SS).

I did drive the car on the first pass of the day - tree'ed a turbo porsche and smoked him by a 10th. lol he was coming like a freight train but The Mark got the W! :)





Here's a video of Ryan's Mustang. He has done a lot of work on The Mark. That car twisted so much the hood pop'ed while launching :eek-large:

Sounds like a good time. What times of day did you make runs? You had good air in morning then it tapered off.
It's always a good time when I'm able to drive the car home after racing it. :) The 12.3 run was at 1:48pm, and the 12.4 run was at 2:51pm.


Great stuff Mike! See you next weekend.
Thanks Norm! Looking forward to it! :)


The Mark weighed in at 4255 pounds with me in it, so there is no problem with making weight at the shootout. I took the best time from the day and added it to my spread sheet, and compared it to the September best time. It appears to be steady across the board, so at least we have not gone backwards while working on the shifting.
