They are used on tons of LSx applications. I've seen them on H2's, Trailblazer SS's, GTO's, etc. Most of the ones I've seen are for folks who want to just do the blower, headers, and drive it forever, much like the base Roush units. Low boost, minimal tuning issues, etc.

Diabolical!

Still impressive that they squeezed an M112 for that.

ditto.. just never really caught on with the S197 crowd, except for a certain few that swear by them. From what I hear, they do last forever and through all sorts of conditions. ONe of the main reasons I considered one. The Roush M90 is actually an inch shorter, though same in diameter. The older Cobras (Eaton M112) respond very well to porting, a smaller pulley and tune for some awesome numbers , though alot of the owners were still ditching them for Kenne Bells..

I wonder why they didn't just use the R2300 tvs rather than the M112? there is another vid of them making 900hp on another motor with the R2300.
