I've got a stick. So is the "preferred" method to do a power brake/ pop the clutch combo?
Thanks,, I wish those would have been some cheapo tires,, they were near new Michelins. :{ They made cool pics though
On my Big burnout pic, I actually put some oil down to get teh tires some wheel speed, then rolled off the oil and did the burnout on the pavement.
With my stock truck, I would run the motor to 3,500RPM, pop the clutch in 1st gear, and STAND on the brakes,, this worked really good the first time, then the 2nd time I broke all the spyder gears in teh rear end. The 3rd time, same result, so I figured that was a bad idea.
The last time I did the diff I had them build it very "tight",, that is the key to not burning up your diff when doing burnouts or donuts. You cannot have the tires turning different speeds. The left and right side must be turning the speed your speedo says.
If you are doing a burnout, unless it's an open diff,, and you experiance "one tire fire" syndrome, let off, 'cause you are cookin' your diff.
If you are doing a donut, and you see, that, as you come back around, one set of tire marks are noticeably darker and the other is very light,, and the rear of the truck does not feel like it's on ice,, let up, cause you are going to be servin' up a dish of well done cooked diff.
Change your differential/axle lube for some regualr stuff, and don't put ANY additive. I'm running all of about . 5 - 1 oz of modifier in my diff. (Modifier makes your diff slipperier,, not more grabby)
As far as a stick doing a burnout,,, make sure you are somewhere you can be alone, and won't get your butt busted for spinning donuts, and burnouts.
My recomendation is to rev it wayy up in 2nd gear, (~3,200) then dump the clutch with your wheelsturned all the way to your left, and once the truck goes around once, and you have very little forward momentum, start applying the brakes, and apply the brakes hard enough to keep the truck from moving, but not enough to start stopping the back tires. (You'll hear/feel it)
On my truck, at 457RWHP, I would rev it to 3,500 in 3rd gear, turned to the left (Left just seems to work better) dump the clutch (don't sidestep it), go around, and when the truck would spin around, and be sliding backwards a little, or would be still, I would hit the brakes.
The reason for that was, 1. My clutch wouldn't hold a dump, and then hitting the brakes (it would slip) 2. it's easier on the drievetrain because you don't have the brakes instantly trying to slow down the drivetrain you are trying to speed up.
My truck had enough power, and the right clutch to do 3rd gear donuts,, but I had to be turned all the way to the left, if I tried just taking off on a 3rd gear redline launch, I would usually burn through the clutch, but occasionally I'd either light up the tires, or bog the motor.
I wouldn't do this on a "sticky" surface, or with oversized tires unsless you have the drivetrain to match (bigger clutch, bigger input shaft, or bllet shafts in an Auto)
I was doing the burnouts/donuts in my dually with 245/75 tires, and that's about all she seemed to like. I tried a bigger tire for a little bit, but it was a little much, maybe you 2500 guys could get away with a bigger tire.
I would recomend practicing in the rain, or snow before trying it on dry pavement. You need to get used to the way the back end will swing around, and how the brakes will affect you.
Good luck, its a risky game, and parts get broken, but the cheers, applause and whistles afterwards usually make it worth it.
See you in Muncie,, I'll be the Dually doin' the burnouts. LOL

EDIT:
I have a video of me doing a donut at night, but I don't have anybody to host it, so if you want it, you can e-mail me at -- email address removed -- it wil better show you the technique I am talking about.
