    Definitely interesting, I wish I was smart enough to tie this into valve timing events with the aftermarket cams, I'm just curious as to when it injects in relation to when the intake opens.

    BTW, we ran it 5 times Wednesday, the last two were no changes except the 15% added on run 4. The MPH gain compared to the prior 3 runs was .89. The DA was 7397 on run 4 and 7340 on the last. The average of the first 3 runs is 7331 so you can see that the air was real close.

    Also, the first 3 60' times averaged 1.358 and the average of the last 2 was 1.337, according to my crew chief pro software it picks up across the board each time. It's running the same times now at 7300' DA as it did in 6400' DA at the beginning of the year and I've done nothing to the dragster but play with the injector timing tables and the AFR since it showed richer.
