let me guess rocky mountain raceway? I ran my 07 mustang GT there which was mostly stock a few years back and that was about what I ran there. that is insane these trucks almost trap 100 mph!

Haha that was my first time leaving the tree so don’t expect greatness. Later in the day I dialed a 14.44 and was .058 on the tree and ran a 14.463 - solid run but mostly luck.

Yup RMR. There were some newer stock Challenegers and Mustang GT’s dialing slower times than I was. Never saw them actually run though.

r/t doesn't affect time or trap speed. the 60' time is what you need to nail.

I have a 2017 Super Crew 4x4 with the 3.5EB and 10 speed auto 3.55 gears and 20" wheels.I don't know how to post pictures but ran a 14.45@95.07 mph last weekend with a 2.143 60ft. 9.311@75.66 mph in the 1/8 mile.FWIW i don't think these 10 speed auto 3.5EB like a Brake Boost launch the old 6 speed yes these 10 speeds no!!!!I did the Brake Boost launch like my 2015 Super Cab 4X4 2.7L Eco Boost 3.55 gears and 20" wheels that truck had 2.001 and 2.050 60 ft times launching the same way!!!Did you just leave off idle with the Electronic Locker locked if you have it?

a 2.1 60' time is either not in 4wd, or has traction control on.

I brake boost from stoplights in 4wd with traction control and RSC disabled, and it launches HARD.

You can't leave traction control on or the PCM manages torque too much in 1st gear for good launches.

Almost the same time as my stock 13 RCSB 5.0! Mine ran 14.40@96.

This guy is at 4500' of elevation(thin air) and has what sounds to be a full loaded truck($60k) and was launching in 2x4. 14.5 sounds solid considering.

Have you had your truck to the track if so what was your 60ft times?There's no 60ft timers from stoplight to stoplight!!!!

It would have probably ran a 14.30's or maybe even 14.20's if it would 60ft like the 2015 truck did!!!!!

True, I was spinning bad on the stock banana peel 265 Michelins.
