Hey dude, The xtm enging has more torque than the axial but the axial has more top end rpm. If your going to race all out then the axial seems to be a better choice. As for the supergharger, it does what it says it will but break in the engine with out it then install the unit and re tune the engine. Thats the safe way to go if your going to use it. I have to tell you that it is a real pain to get it just right but when you do......DAMN THIS TRUCK MOVES!!!! And you must hook up the aux preasure system since a savy tends to run lean at half tank. It should look something like this...

You also can expect to see temps higher than your use to seeing from the engine since your funneling more fule into it. I would use 30% nitro as well because you can run a richer engine and get great top end from it. Just make sure you order an additional idler pulley to rout the belt away from the silicone coupler on the carb. The kit you looked up is the one you need but order ALL the additional parts with it. You will also have to be careful on what gears you run since the belt can get very close to the slipper clutch nut. To use the xtm with roto start you need the back plate from the xtm 247 motor and swap the parts and the roto will bolt on to it.
Any problems, come and find me,I will help you
