Magnum 46 Xls & Tower Muffler
I just started breaking in this new engine and all I can say is "WOW." 
Cover your ears this engine combo screams. 
This is my results after 18oz of fuel. I am sure these numbers will improve even more. These figures are constant not peaks. All I was looking for was hovering ability for a 4.75 lb fun fly plane.
APC 10-6 15,150 10%WC 80-20 syn-cast w/2.5 oz of extra Castor Oil.
APC 12.25-3.75 12,600 WC 80-20 syn-cast w/2.5 oz of extra Castor Oil.

MAG 46XLS
Agreed! I've got 2 and run them with the muffler baffle removed. Performance is nearly as good as with the Tower Muffler, which currently is not on either, but just out of laziness to put it back on. Currently running around 13,200 or so with the narrow blade style APC 12x4 prop, 15% Wildcat, 18% synthetic with 3-4 oz extra castor added per gallon (messy!) and OS#8 plug.
For some reason, the performance increased when I added castor oil. They both drop off a bit when I go back to the normal 15% Wildcat. So, I stick with the added castor!
PROPS - FYI
I've used the 12.25x3.75, 11.5x4 funfly props and have recommended them to friends, but the (new?) 12x4 APC works better for me. It is narrower, lighter, and spins up faster for more responsive hovering control. In my 4.75 lb Magic Extra, this engine/prop combo is totally amazing and performs well beyond my expectations.
