ok from this site ive learned that less da is good for e.t.'s but according to my timeslips im not seeing it. im going to put up two different time slips with no other changes to the car ive run three tenths and two mph quicker in worse da on the same 60ft. whats goin on? i always thought that better da would equal better e.t.'s all else being equal.

2200da 1900da
60ft 2.172 60ft 2.181
330 5.773 330ft 5.870
660 8.687 660 8.83
mph 85.05 mph 467.28 <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> timers screwed up
1000ft 11.184 1000ft 11.378
1/4 13.292 1/4 13.526
mph 107.21 mph 105.32

no changes to the car other than the weather. i might have had a small change in the maft during this pass but ive got 7 other passes that are all in the 13.50's in the better weather. also if this makes a difference the humidity in the 2200da was way down but in the 1900 was way up. i thought thats what it was but better da should still be better for power right? btw, anyone know the elevation of cecil county dragway?

i thought it was closer to sea level. hmm ive been running is worse weather than i thought then i was figuring it to be about 50ft above.

on the better pass it was 87 degrees 33 percent humidity and 29.78 pressure
the other pass was 82 degrees 96 percent humidity and 29.92 pressure.
