Racer 1320 makes a good point"Make sure water temp is exactly the same every pass, burnout duration is exactly the same every pass, launch RPM is exactly the same every pass, shift points are exactly the same every pass and you are putting the car into the beams at exactly the same spot every time."
It's possible that the motor was a littler colder on the last pass which would reduce it's tendency to detonate at the top of each gear and at the traps (You can't always hear when they are detonating) which would make the motor run better and pick up all the way down the track. If you don't have a weather station to calculate density altitude I would recommend that you track and log the air temperature. It's a reasonably good indicator. If the temp drops 10 degrees, depending on your jeting, you could pick up as much as 0.1

Thanks all for the help, I finally got my issue taken care of. That electric water pump motor and 2 electric fans took care of it. For driving on the road though i'd say i would need an 8blade water pump to drop the temp even more. Since Lucas Oil Raceway is only 20 min from my house I don't have far to drive and it barely hits 190 on the temp gauge now. I was bracket racing at the Fall Classic this weekend first pass was the slowest all day then it got faster. 8.57 /8.554 /8.544 and i broke out 3rd round it went a 8.508 this was at 8pm saturday and it was cooler. I have to say i didn't expect it to pick up that much.
