Finally broke into the 12's -------Barely

Just barely

After about 6 runs ranging from 13.06 - 13.01 I finally hit the 12's


R/T .634
60' 1.793
330' 5.308
1/8 8.255
MPH 83.13
1000' 10.822
1/4 12.998
MPH 103.80


Still have a low MPH but have heard a number of different theories on this one from tuning to the lack of 1.6rr's. Not sure why but still working on it.

Absolute Pressure 29.126 inches Hg 986.33 mb
Relative Density 96.47 % 96.47 %



Pretty chilly right here now, car is in the garage though - not taking it out today. Gearing up for the Broncos game tonight

Does anyone have datamaster logs of their mid/high 12 sec runs?

The hooker shorties arent helping you any. Get atleast 1 3/4" headers. if you really have the hooker shorties they are only 1 5/8"...too small for a cammed car IMO.

Re: Finally broke into the 12's -------Barely

Nice run.


My best with a CAI AFPR cutout 2800 stall and 3.73's was a 13.216 @ 103.97 on a crappy 1.876 60'. I know I could have gotten 12's with just that, but now the cam/heads/shorties go on.

Um.... 12's with stock heads on our cars is relatively easy with traction...

I run Hooker shorties and a stock I-pipe and hit 350rwhp w/ stock heads.

The shorties aren't that bad.
