    My car is a 2018 Mustang Gt with a JLT cold air intake, long tube headers, Corsa extreme cat-back, tune, E-85, half shafts, Race Star drag pack, and BMR suspension.

    My best E.T. of the night was an 11.55, my best trap speed was 122. The DA was 2350 and the car is full weight.

    I kinda hoped for an 11.4 but was having a difficult time getting the launch RPM’s high enough prior to starting. I feel like I should have ran an 11.4 but my best 60 foot was a 1.7.

    I have a video that I tried to upload but received an error message. image.jpg

    Weird question/comment.....I’ve raced at drag strips for years. When doing the burnout I always just power brake it, let off the brake, stay on the accelerator for maybe another second and just roll to the starting line. This was my first time doing this in an automatic transmission. The transmission didn’t seem overly happy with that technique. I don’t know how else to describe it. I think the stationary burnout portion ended with the transmission in 2nd gear before I let off the brake (and stayed on the accelerator). When I finally let off the accelerator and rolled to the starting line the transmission clunked pretty loudly and downshifted abruptly. The car actually almost stalled.

    When doing the burnout with the 10 speed auto, what gear does everyone usually finish the burnout in? Should it just be limited to 1st gear?

    With my previous mustang, I always did a 2nd gear burnout (3.73 rear gear).

    Any feedback is appreciated.

    Is a 1.5 60 ft feasible with my setup on the foot brake? I would love to get my E.T. down to an 11.1. I know I need to add more revs prior to launching.

    I'd say that's a pretty good time for summer. Your sixty isnt bad. You can definitely get a 1.6 sixty on your set up. Even if its only a 1.68-.69. That would have got you your 11.4 you wanted. An 11.1 might be doable this fall when the DA in your area drops down near negative. And you hit that 1.6 sixty. I've seen a 3/10 change in E/T. Just from going from summer to fall DA.

    Use the line lock and your 60’ will drop. 18 psi, 2k launch, line lock burnout should get you a high 1.6.

    Not bad check my video and it’s easier to do a burnout using the line lock

    Doing a burnout with my A10 I use the line lock starting in S 1 take to 7K then shift to 2 to 7K, release line lock and drive out of it. At the line put back into D. With your setup you will never do a 1.50 60 foot.

    On a foot brake 1.68-65 it’s possible

    I appreciate all the feedback/help. I’ll give the line lock a try. I’ve messed around with it a few times back when I had my 17 Mustang GT that was a manual.

    My initial air pressure was around 18.5 psi but it did creep up to 19.5 psi or so after the tires were heated up.

    It’s definitely easier to run solid times in the automatic. However, there’s more of a learning curve than I anticipated.
