Towing jeep--need power

I tow my jeep with an Expedition 5.4L V8. Holley makes a supercharger for this motor stating it will give 110 more hp at the rear wheel over stock!!!!! My stock engine makes 260hp ---345 ft lbs of torque @2300 rpm at the flywheel. So about 212 hp at the rear wheel. (according to a dyno test on a similiar expedition). So now I would have 322hp at the rear wheel--not the flywheel. Flywheel would be 400hp!!! This is what Holley claims with stock exhaust.
Has anyone tried this new supercharger and if I did this----I know I'd put my foot into it up steep hills in the mountains while pulling my jeep so then what would I break on the expedition? Driveshaft, ujoints/?????? Let me know if anyone has done it and had any other problems surface.
