I have a 98 Z28 A4 and am planning on upping the power but Im afraid im gonna bust my axle. Just last week my buddy busted his 99 z28s axle at the track with a 360 built bottom end, cam, bolt ons, and higher stall torque convertor. He broke it before we could dyno it. Does anybody know the torque limits on the 4L60E and the stock rear end are?

Alot higher then your 6spd cars. What kinda tires did he have?

theres no definite hp that the rear will snap at. a 6-speed will almost always go sooner. as for the tranny...the same thing goes.

Your POS 10 is gonna go if your racing regardless, power adder or no power adder. I would just start saving for a 12 bolt now...

for the rear end, I think its more of how hard your shock it - like launching with a 5000 rpm clutch drop with slicks and immediately hooking, hard shifts, excessive wheep hop, that really kills it.

Mickey Thompson ET streets. It sucks he broke his axle doing a burnout at the track. And even with a busted rear gear his car ran a 12.0

How do you run 12's with a broke rear end? What broke? I dont know about you but i have seen rear ends break. Most of the time cars dont move after that.
