4x4 boosted launch?

[theblacksmith]

I've read several posts that this is talked about... yeah, I'm for real... how's it done and is there any danger in hurting the tranny?

Flip the switch to 4X4 High, power-brake until your boost is where you want it, and then let er' rip. Not sure on the tranny. I've done it a few times, and haven't noticed any ill effects *knock on wood*

i don't see it being a good idea.

4wd is built to be driven in loose terrain where the tires can spin, they don't spin at exactly the same rate as the rear, so the lose terrain allows it to work properly with no binding. on drive pavement you will have binding.

now after saying that, people have done it with no issues, i never did it because i can't afford to break it. i just wouldn't do it over and over and expect for it to last.

Its fine i do it all the time

Ive done it just as the second poster describes dozens upon dozens of times. Theres no binding when you are going straight.

I have done it a bunch of times and my bts tranny will be here on the 6th

if the front has different gears than the rear than why does the manual say its ok to run it in 4x4 up to 75 mph, i think if it was going to bind i don't think they would recommend that. so i'm pretty sure the front and rear have the same gears.

to the op, don't worry, you should be fine

the 4X4 is designed with slightly different ratios so that the front tires 'pull' you, but its so minimal that it doesn't harm anything, the tires will slip enough to compensate even though you wont notice.

the stock tranny may take this abuse for a little while but its almost certain it will fail sooner than later if this is done on a normal basis.

No manufactured vehicle EVER (not even chrystler has came with different gear ratios front to rear). try running a 4.10 ring and pinion in the front and a 3.73 in the rear, put it in 4wd on pavement and tell me you don't notice it. when you have a driveshaft lying on the ground you'll eat those words
