There is more to a fast vehicle than just the engine. It requires that the whole vehicle be tuned for what your intended purposes are. Weight reduction is important, as well as sensible gearing. gearing that works for what you want is completely wrong from what you would use to scale a rockface. You don't need one-tons or rockwells. You don't need superchargers or turbos. Nitrous is a possibility and will make it easier and cheaper to do, but you don't NEED it. All of my Jeeps are multi-purpose, and the number one purpose is going fast.....Jeep style. It's not hard to make a good runner that can score some nice kills in stoplight to stoplight drag races. A full on "fast" Jeep takes alot of work and money, but you don't need that for the prey you'll be hunting. I'll stay out of a long winded technical response, but I'll answer any questions that I can.
Go watch a real(as in serious competitors) organized mud racing event and then tell me a Jeep can't be fast. Most of what works in mud racing also works pretty good on the pavement. Same basic build concepts.
