A friend of mine had a true trac in his truck and right after he put it in I wanted to see how well it help posi. I have 8 minutes of video where hes spinning the tires the entire time. One time it swung around so hard it lifted on tire off and still never unlocked.

I love mine for the street and works very well in most drag applications. I have approx. 50k miles on it now. I did have one problem with mine though.
The bolts on each end cap that hold the unit together backed out. When I was driving, I began to have a huge jerk like I hit a hellacious pot hole but there wasn't any of course. After 3 or 4 times of this happening, I took the rear cover off to find all the bolts to have begun to back out or have been sheered by hitting the housing when they backed out. The unit was being held together by the bearings and the housing its self.
I attribute the problem due to several 5000+ clutch dumps on slicks with a few of them being on a 150 shot. It takes 2-3x's the torque from an automatic to put the same kinds of loads on a rear end as a manual does dead hooking. Heck, I snapped an axle and Parish8 never even did that with stock axles.
Basically, the worm gear design pushes outwards on the end caps during heavy loads and probably stretched the bolts. I replaced the bolts with new grade 8's and red loctite. I have had no issues in 20k miles but I haven't put slicks on it again either.
So my opinon, if you are running an automatic, beat the hell out of it. If you have a manual, be careful with the hard launches at the track on stickies.

I have had some weird symptoms since I installed mine.
It just seems like I get a lot of traction all the time no matter what I'm doing
Even with the g-80 working like it should, this hooks way better.
LOL
It's pretty surprising how it just seems to work great always.
