I'm heading the the track (1/4 mile). I have a 2013 sierra with the 6.2 and 3.73's. I assume I should launch with traction control and stability control off? Hold the rpm's up as high as I can or not? It's a bone stock truck besides the denali 20's.
You awd or 4x4?
Awd-turn TC and ST off hold the foot brake and put the glass on the floor and wait for green.
4x4- Turn TC and ST off put truck in 4hi hold foot brake with gas on the floor wait for green and after 1-2 gear change put her in 2wd and down the track you go.
I believe factory stall is like 1200-1300 something like that. It's been a while since I've been to the track or even launched mine.
6.2 comes stock with a little over 400 HP. In the 1\2 ton chassis, you're looking at something like 1000 lbs lighter vs the Duramax in a 3\4 ton. I'd argue that launching the two vehicles is actually pretty similar...
With the 6.2 you're gonna be burning out pretty badly if you launch in 2wd. If you just punch it with no rpms built, you'll have no power so bad times. If you build rpms, you'll have too much power and spin out. If you roll off the line at half throttle and than punch it ANYWHERE under 20 miles an hour, you'll rev to 5k and burn out. My 6.2 with 3.73s will snap my cooper discoverers loose at 20 (2-1 shift) on bone dry pavement with 4 people in the cab. Id say what the others did: launch in 4 hi with revs, and drop to 2wd after second gear. Or just drain your rear tires down to about 20 psi and you might be able to get traction in 2wd haha
