Hi Martin, Welcome.

No, the emaxx mount is not a wise thing to use. since it's a simple straight plate it's hard to get it on the chassis/diff without too much flex. (flex is killing for the spur/pinion)

You are better off with getting an L profile aluminum and make your own mount.

the kyosho won't fit the mugen. that's for sure.. You could ask Mike to have you made an adapter plate to fit the Mugen diff. that way you can use a 51T spur.

The 7XL works very well in a buggy on both 12 and 14 cells. The 8XL will give you slightly longer run times and will get a bit less hot.

I used the 7XL and loved it in terms of power and temperatures.

The 7XL is most certainly not the limit for the 9920 on 14 cells. Some users here even used it on 18 cells on the 9920.. (it RIPS) that is pushing it, though but since you are leaning towards the C can with the heatsink you will be fine with the 7XL on 14 cells.

The 8XL however will run slightly cooler and give you a bit longer runtime. But it will also run a tad slower.

RChippie can confirm the power of the 7XL on 14 cells in a Mugen buggy.

I can't recall if the HB diffcup fits the Mugen diffholder, this HB cup would enable you to use the kyosho diff, but you would also need a set of new internal gears (HB uses a 4mm x-pin) and it also uses 6mm output cups, so you would need these as well. (that is, if it fits at all)
