Mamba Max and 9XL

I'd like to use a Mamba Max esc + a Feigao 9XL or maybe 10XL in a 1/8 buggy. Possibly a 777 SP2. That system should be ok, but how will it perform in the 1/8? Am I completely wrong when I think that the Mamba can handle the 9XL?

I know there are better options around. I've got the Quark in a Revo. Two of those and my wife would take away my key. I'm trying to do it cheaper and I think it should work, but someone elses opinion is always appreciated.

And I'm only using 2s or 3s lipo.
