Sorry but I have not, in my old 65e the Borg Warner's held 550-600hp behind 6k lbs. For what it's worth.

 

ill look into them, but has anyone ran the Raybestos z-pak?
they work fine, unless you are pushing major HP. At least thats what several people say. Im a B. Warner type of guy.

 

I think thats what i put in this 60E that went in my Tahoe..they were cheap and instock so i got them

 

Raybestos Blue-Plate Specials or Alto Red-Eagle. The Raybestos Blue Plates worked well for me when I was still running a 60-E in the Tahoe. They eventually failed too, but it was because they were used up (41k supercharged miles), not because they started slipping. The Z-pak tends to distort from overheating in high-torque apps, I would not use those.
