I believe that's the smaller version C30-84 which might just work perfectly for our 3.2, but the max power envelope doesn't allow any room to build more power. so if your happy making 300 hp it might be good enough.

The C30-94 looks like it's good for 400+ hp and pumps out over .33 kg/s of air mass.

edit that first part; the C30-84 is on the declining side of the power envelope, so it would be more efficient to use C30-94 impeller. That's going on my Christmas List, hoorah!!!
