Anyone Use Ofna Torsen Diffs?

[TexasSP]

I am looking at trying ofna torsen diffs in my revo in Mike's cups and wanted to know if anyone has experience with them. Mainly I need to know if they are of decent strength before sinking 350 into this project and blowing them out. This will be with a neu 2.5d on 6s.

Here is the specific diff I am talking about:
