Well my goal for this year was to run 10's on a drag radial with this 3500# plus car. Well first time out with the AOD it went 10.50. So with cooler air in the forecast and a 3.15" pulley sitting in the garage I figured I would try to get a single digit run. :p So I swapped out the 3.33" pulley for the 3.15" and headed for the track Sunday. The DA was about sea level all day. So that was great. And the track had sun to keep it warm.
The first pass I ran a 10.039 @ 138.10. The tight 2600 stall was killing my 60' as usual. Nothing like having a low 10 second car with a 1.65 60' :? Looking at the data log Bob Kurgan and I saw the timing was high. Well I made a tuning error. So bob corrected it and we went back for another pass. 10.034 @ 139.49. Damn not what I was hoping for. haha So we checked the data log and made a small adjustment in timing. The fuel correction was less than 2% the whole run. I tell you that Kurgan can tune! lol So the next pass I finally ran a 9.91 @ 139.95. Another small timing adjustment and it ran 9.90 @ 140.12. Getting quicker little by little. That pass I hit the rev limiter on the 1-2 and 2-3 shift a little. The 1-2 shift is a little slow compared to the 2-3 shift. So I need to get used to that a little. I was also next to a friend who cuts lights and has a low 1.4 60'. So I am sure me playing catch up had something to do with me over reving it a little. So we left the tune and just looked to make a clean pass off the rev limiter. I made a pass just barley hitting the rev limiter on the 1-2 shift and it went 9.832 @ 140.24. The staging lanes were closing so I ran right back to the staging lanes that were empty. With it still running and no cool down the car went 9.941 @139.76. I was real happy with that. I can hot lap the car and loose very little in ET and MPH.
Here is the timeslip.

I think over the winter I will send the converter out to be re stalled. Maybe add a trans break too. I also have to address the issue of hitting a 7200rpm rev limiter with a 275/60/15 drag radial. I might have to drop the gear down some more. It is a 3.70 now. I had visions of running a 275/40/17 drag radial but I think I would need a 3.00 gear to make it out the back door around 6500. lol
It looks like I need a cage and a few other items as well. Kurgan is already talking YSi for the car next year. I think he has more in mind for the car than I do. hahaha We will see what happens. I will keep you guys posted.
