I've never heard about launching in 2nd. I have the 6 speed. Probably wouldn't be as successful for me. My biggest problem is not being able to go directly to the floor with the throttle, because of wheel spin, and risking the ECU deciding to shift to 2nd too early because I guess it doesn't feel like I'm going to WOT it.How to Launch a 2018 Ecoboost Mustang, equiped with stock 10R80 Transmission, stock torque converter, 3.15 Gears, 275/40/17 drag radials and BMR drag springs.
I've tried a few different methods of launching over the past couple of NMRA seasons while competing in a foot brake only class, at some of the best, professionally prepped, 1/4 mile drag strips!
To make launching even more important, we qualify on reaction time.
I originally lanched in 1st gear at 1750 rpm and let the transmission shift itself with the gear selector in "S" and electronics in drag mode with advance traction control off. But, was not able to get my r/t under a 10th of a second.
I then went to launching in 2nd gear which allows us to push up our rpm to 2500 rpm. I was then able to get my reaction time under a 10th of a second. But because I used my paddle shifter to advance into 2nd, I had to continue manually shifting, which reduced my average 1/4 mile ET up to a 1/2 second, due to delays between gear shifting!??
How are you guys lauching?
Sorry, left out that my class runs a "pro-tree" and that I "deep stage" I also "go on yellow" and haven't been able to "red light".When you roll into the beams and you turn on the first light do you then go as slow as humanly possible to just barely get the 2nd light to turn on? If not you need to do this. If effectively lets you get a "run" at the beam before you trip the start timer in your lane. This can help reaction time and E.T.
The advantage of launching in 2nd gear, with a 10 spd. is that you can push the rpm up to 2500, which gives me positive boost upon launch. In 1st gear, if I go much above 1750 rpm, I push though the lights!?I've never heard about launching in 2nd. I have the 6 speed. Probably wouldn't be as successful for me.

Most definitely. You won't be able to shift through the gears nearly as efficiently as the PCM.
A reaction time of under a tenth of a second is pretty awesome!
💪I ran 16 psi in the rear and 48 psi up front last season.

I don't have any issue with wheel spin. I ran 16 psi in the rear and 48 psi up front last season.
I use the line locks in the burnout box, and once your tires dry off and warm up, you can fill a force trying to turn your front, but as soon as my RPMs start to drop, I realize the line locks to prevent lugging the motor. Not sure what would happen at the line. Plus in a foot brake only class, your not allowed to use any electronics (line locks/trans back) at the line.If you use the line lock will it still push thru the lights at 2500 rpm in 1st or does it spin the rear tires. If you have a cobb AP tuner you can use the trans brake feature to stage and hold car in place for the launch.

Sorry to hijack the thread, but you're running that with what in the front? The PP wheels? The stock 18" wheels? I have the PP wheels ... is that still too big to offer a difference on the type of setup your describing in the rear?I got a 2nd set of rear wheels and put some Hoosier drag radials on them. They both fit in the trunk just fine along with a small Harbor Freight aluminum floor jack. Easy to swap them at the track. I don't like driving there with them on because it really shortens their life span. I'm about an hour from my local track.
Reread your initial post and missed the foot brake only rule. So, I guess that would also rule out the use of a Cobb AP trans brake feature.I use the line locks in the burnout box, and once your tires dry off and warm up, you can fill a force trying to turn your front, but as soon as my RPMs start to drop, I realize the line locks to prevent lugging the motor.

Something Brad Gusler (1st guy to get an Ecoboost into the 9s at an NMRA event) did, years back, was add a second set of brakes to his rear disc, similar to what the "drift racers" use. Seems to of worked for him! Only drawback was he had to eliminate his emergency brake.
Know this is a bit old and you might’ve found a solution that works by now or know this already but you can engage the paddles and get into second at a complete stop and as soon as you launch push the shifter back into “D” it’ll rev out the way you want and you won’t have to manually shift with the paddles. Keep in mind that Ford designed the shifter to be pushed from “S” to “D” WITHOUT having to engage the little shifter button, that way you can’t accidentally throw it into neutral, just push the shifter with no use of the button and it’ll stop when it hits “D” hope this helpsHow to Launch a 2018 Ecoboost Mustang, equiped with stock 10R80 Transmission, stock torque converter, 3.15 Gears, 275/40/17 drag radials and BMR drag springs.

PS: My class runs a "pro-tree" and I "deep stage", plus "go on yellow".
