Working cart speed info

[Krazy-K]

I'm sure this has been gone over in the past but I cannot seem to find it. I have an 11 precedent with a 6inch a arm lift and 22 inch tires. 12 inch week if that matters. I use my cart mostly as a campground cruiser but do have a hitch on it and occasionally use the cart to work, towing a 4x8 utility trailer. I would like a little more speed but mostly want more torq. The cart will top out at 18 (stock motor and controller ). I was thinking an XCT controller (not sure which one) and possibly a bandit motor (could I tow a realitivly heavy load and not hurt the motor) Speed goal is simply to accelerate like a stock cart. ( mine takes a little time to get moving)
