Might be kinda cool, but there are other ways I'd rather spend my mod money in the mean time. Personally, having driven vehicles with both turbo and superchargers, I'd rather have a supercharger in a Jeep, for the same reasons you said about lag-time off road. But, on the other hand, with my style of wheeling, I've got enough power as it is. I'm not one to use lots of power when wheeling, I prefer finesse and skill to get me through, over, and around obstacles, but I'm sure for many Jeepers, more power would be great. Maybe my opinion would change if I had a Jeep with more power to begin with, but pretty much all I've wheeled is a 4-banger Toyota pickup and my YJ, and I'm used to the lack of power. I think if I were to get into something now with a lot more power, I'd definitely break something or kill myself!
Who posted the thread last year about the supercharger made with a leaf blower? Was that Snitty or Junkpile?
