Front diff doesnt lock, and I never figured out a way to do a 4wd burnout (besides playing on the street, I mean a real burnout to heat the tires) so when you launch, one front tire spins pulling the truck one way, then when the lsd applies power to the tire with traction, the one that was spinning stops and the other one starts, lets just say the wall gets close QUICK

 

Its scary as hell at the track

 

That sounds like fun!

Was your truck AWD? My t-case is selectable, so I do a quick spin of the rear tires just to clean them up, then shift into 4x4, then stage. I always launch straight, and cut 1.7's with tire spin. ET is 12.3, I've never experienced anything like what you described. I thought you were gonna tell a story about exploding something in the drivetrain.
