Why in the world do you want to roast your tires?
The traction you get now, most drag racing teams would die for.
I know when I take mine for the first run, I'll just drive thru the water trap, sit on the line and wait for the other guy to show off, and launch like a horse when it's my turn.
If you REALLY must though, your best solution is to find someone with a 2wd that want awd and swap parts.
removing the front shaft alone won't cut it, power still gets applied to front when wheelspin occurs
