I was quite joking about the crazy setup, since it will be an overkill for both the truck and your wallet not to mention that the E-maxx can barely contain one of them and not two, but just like Promod said any good XL motor will help along with a cooling fan and reasonable gearing. You might need to modify the tranny gears, for the plastic ones will surely suffer from the excessive amount of pressure.
