The 3.4, even stock has a fair hp:weight ratio but by no means is it going to be sports car fast. I have the supercharger and it pulls hard in low gears and has no problem hitting 100. Could go faster, but why would I need to? I need to get the URD
7th investor kit to get the most out of it though. There are a couple superchargers for sale in the 1st generation marketplace, 2k and 1.5k iirc, not cheap, but worth it and performance always comes with a price. You really have to ask yourself what it is the truck will be used for and do you really need the extra power. Good luck man. Btw, the charger requires you run 91 octane...more money right there.
