I am guessing that it will run high 11's.

99RCSB Broke because I wasted thousands and thousands of dollars on my truck.
Everone puts down the auto trac as bieng weak. Anyone broke one by launching in 4wd then shifting to 2wd?
I launch 4hi, have been since my truck had ~10K miles on it, I'm at 45K now.
I cut a 1.57 60' right after this. I drive my truck to work every day, it's my only 4 wheeled transportation.

My other ride is a '91 Electraglide custom.
I have never heard of one being broken for that reason. The early ones had a few design flaws that caused some case failures but other than that no.
Parrish ran 1000hp and never broke it. I think it was an autotrac. Not 100% sure. Some one correct me on that If I am wrong.

pretty sure you're correct. Also, mine switches back into 2wd while under full power, I know because if I shift it too soon it's all over for me

I ran a 14.05 in 2HI with a 2.13 60', spun a little off the line. Then I ran a 14.19 launching in 4HI and pushing the 2HI button after the 1-2 shift. 60' was 2.08 and I kind of messed up on the 1-2 shift. I was a little late and bounced off the rev limiter, otherwise I would have been a little faster.
Big slow mud truck with a TUNE!!!!!!
Found some more information on this subject. Keep in mind stock48 is running low 10s

nice info, better not try to change from 4h to 2h then.....
Yeah, but he is also running 10s. Apparently a stock transfer case can handle lot of power. Except for STOCK48, I have not heard of a stock transfer case fail...in a 4WD or AWD form.

What if you have a manual transfer case and you do the 2low mod where you put a switch in to disconnect the front axle in 4 low. Then launch in 4 hi and about the 60 ft flip the switch to disconnect the front axle and still leave tcase in 4wd. Would it work or help?
