hey, this may be a stupid question, but when i burnout, i usually put it in neutral first to get a good boost then put it in drive. my friends tells me that they put it in first gear while holding down the brakes, then second still holding the brakes, then drive. how do you guys burnout?

Put it in third, T/H, and hold the brakes. I only have the 5 speed allison in mine. How are you building boost with no load on the engine? Just raising the RPMs doesn't "build boost" in and of itself for the most part.....it helps to have the load on the engine. I would think that you are going to either break something or burn something up with the way that you were doing it now.

o, i thought bringing RPMs up builds boost. nvm

In and of itself, not a whole lot. Install a boost guage and see. My truck will only show about 1-2 psi when I have my elevated idle on 1700 rpms. My boost guage is on my TST, so it is digital.

so too build boost, you have to hold down the brakes while in gear? because i thought it builds boost in neutral too.

o yeah, i dont have gauges yet.

No load = no boost You have to load it with the transmission and the break. Just hold the break untill you feel it want to push through the breaks and then just nail the throttle and they'll light up no prob.

Being that you have a lbz alot of them had som traction control BS that makes it kinda hard to get the burnout through the 1-2 shift but if you play with it enough it will go through it! I would put the truck in second and leave it there, being stock i dont know if it will have enough to do 3rd!!

Yes, hold the brakes while in gear and roll onto the throttle. It takes some practice not to hold the brakes too hard.

ok thanks, just wanted to make sure before i actually do it. dont want to be stupid and break something.

and also too, do you guys do the same thing before the tree goes down? (drag strip) i know you make a burnout before your next up but what gear is it in rite before you take off form th tree?

Drag racing. put it in drive 4x4 and do the same thing hold brakes, spool the turbo untill u feel it start to push and just hold it righ there let up pun the break just enough to let it bump the second staging light wait untill the lights fall and leave up on the break and mat the throttle.

burn outs are not needed with a 4x4 especialy on street tires, try to avoid the water box if the track guys will let you!!!

If you want to run in 2x4 dont spool it up much or it will just blow the tires off!!!

ok, just to make sure i got everything down rite:

1. drag launch- spool up by holding down the brake while in drive, then let off the brake and hit the throttle?

2. burnout launch- put in second or third, hold down the brakes and hit the throttle, then put in drive, then let off the brakes and hit the throttle?

I would not put it in drive when doing a burnout. You could grenade the tranny. Once' the tires are spinning, no need to make them spin a whole lot faster. You might want to wait on doing burnouts until you can pay for new parts if they break. The whole thing "you play, you pay" goes with this..

With my truck only being 2wd i do a burnout a little pass the tree so i can launch a little harder. I can only pull anywhere from 1300 to 1500 rpms to launch.

NOOB question??? When launching in 4wheel drive after you get going do you shift the truck into 2wd mode or leave it 4wheel. does this affect the t-case at all with power and torque???

the best way to do a burn out with the LBZ is put it in 1st gear in manual mode and then apply the brakes and the throttle at the same time and as you gain rpm's feather out on the brake but don't release right away and when the rpm's hit up towards 3K shift into 2nd gear and do it again and then shift into to 3rd and as you shift into 3rd release the brake and smash the trottle and hold on for the ride..

heres a look from the end of a 350FT burnout i did

heres one from the starting line

heres the Dually showing off a bit

To answer your question keep it in 4wd. The transfer case will not fully dis engage until you bring the truck to a stop.
