I am confused. I have gotten my 60 foot times fairly consistent in the 2.15 range. With that 60 foot time I have my best ET and trap at 13.84@101.75. After installation of drag bags (and 25 psi) my wheel hop is gone but my times are creeping up and are now around 14.2@98. Does an additional 10 degrees F make that kind of difference? Any other ideas?

Well, it can make that much difference. You need to know the DA both times you run.

Temp and condition changes can make 3-5 tenths difference between good cool air and bad summertime air. The drop in mph could mean a few things.

#1 Wind (likely headwind. 5 mph headwind can drop .05-.1 in time and 1 mph)
#2 Air (every 1000 ft of DA change can be around .1-.15 in elapsed time change)
#3 rubbing or drivetrain hp loss (Not sure what the new 60 foot times are, and the spinning could have kept the rpms higher than a dead-hook slow acceleration). Stock converter I'm assuming?

More info needed!

DA was within a hundred feet. No wind. Everything stock. Without pics I really don't know for sure on the spinning stuff. 60 foot has gone from 2.2-2.3 down to consistent 2.15. It feels like it is hooking better but I really don't know for sure. Also I didn't get a chance to compare the ET's at the intermediate distances. Also I saw on the GTO section that heat is a major killer so maybe that is my answer.

maybe the trans is slipping?

Maybe you're just doing SOMETHING a little different on each run. In my old Integra, my best run ever was 14.97 @ 93.82, and that was with a 2.37 60' time. I cut a 2.25 later the same night, but my et actually ended up being about a tenth slower. But yeah, temp can make a difference. Those runs were made at ~40 degrees, and when I went back in ~85 degree temps, I couldn't get any better than 15.4 @ 90mph
