hmmm.... here's what i've gathered...from ppl online (im doing the same basic setup. so i've been searching)
"I have the 7.5 in my car still with my 351w and I haven't broken it yet and I wouldn't say I was being easy on it"
"from what ive heard about the 7.5's in the newer v6's is that 300-350 rwhp is about their limit. but ive heard people busting it with 215 rwhp, and ive heard people still launching with 350+"
"I've heard a few different replies anytime I ask what the horsepower/torque limit is on the Ford Racing 7.5" Posi-Trac. I've heard everything from "Don't go over 300hp with one," to "Don't even bother with one, you'll be lucky to keep 250hp in one", and I've also talked to a guy who had a supercharged 2000 V6 making 450 at the crank on the 7.5" rear."
"As long as you don't beat it often at the track even a factory 7.5 rear will be fine. With prolly 10 total times to the track from 301rwhp-436rwhp never had an issue. Still on 7.5 rear with just 3.73 and posi added, no upgraded parts yet. "
so there you have it.... hope it helps.
mine is scheduled to be installed so i have high hopes that the 7.5 w/ 4.10s will hold up.
oh yeah.... i also think that a TC or high stalls will be a big factor too. if you're launching at 3k, the rearend will be affected.
