Of course I am not as fast, but the broken pump shoe has cost me 4.5 mph.

I should post pictures of what I did ... I am travelling constantly lately, so no pics at the moment, but I drilled a hole up from the rideplate tab (center) grate mounting hole into the pump shoe. I then scuffed up the shoe real good, cleaned it with acetone, and layed in two layers of carbon fiber/epoxy resin. I then redrilled the hole again, ground down that area a little, then fit a medium SS fender washer, and a special t bolt nut (zero protusion, sits flush on top of the fender washer) then bolted in a SS bolt from the rideplate tab hole thru the fender washer/bolt combo. It all sits flush top and bottom ... I then layed on another layer of carbon fiber and epoxy resin over that ... then sanded a little and painted one last bit of epoxy resin over it all to make it super smooth. The carbon fiber wrapped over the lip of the shoe as well and I ground it just enough to fit the grate and girdle in.
I also added the R&D girdle at the same time. So now the pump shoe is bolted and CF/resined to the ride plate (and is seriously reinforced with all the CF/resin) and the intake grate is fastened securely to the girdle/ride plate too.
Very easy to do actually and it is now super strong. Now if I could just get off the travel treadmill and actually ride my ski I would be happy!
By the way, to give you an idea how strong the West System epoxy resin it, I ground out the bilge bumps in two of my adj ring nozzles, plugged the holes and then poured in epoxy resin and let it harden inside the nozzle. After two seasons of riding, both nozzles still look like the day I did it ... no wear, no chipping, no scratches even, the resin is still crystal clear and see through ... and that is INSIDE the thrust nozzle. So with proper surface prep, the stuff is incredibly strong.

the shoe split right down the center (from the grate)of the shoe and peeled back up, starting underneith, the R&D girdle was gone and also the brass inserts

Boy are you lucky that grate did not rip out and throw you off the ski. Happy you found it.
