Thanks for the insights..I think that’s enough to put me off that route...if anybody can point to a well suited turbo with intercooler kit for an 04 TJ I would be interested..otherwise I’ll resign myself to going sedately..I still think it's a great supercharger as long as you aren't foolish enough to believe it's a "kit".
You'll end up putting around $2000 or more into making it run right. I also think the fact that it requires the use of an aftermarket radiator, an electric fan, and has a history of overheating issues in warmer climates due to this is a potentially big deal.
You can obviously solve those issues, but again, you're going to spend at least $2000 or more on top of the kit to get things sorted out, not to mention you'll still need to invest time and money in some good dyno tuning in order to get it running really good.
At the end of the day, it's just not worth it to me. In terms of superchargers, I think it's the best one for a TJ. However, I'd pick a turbo any day over a supercharger if I wanted to go down this path again.
Hardly surprising that an engine design from 1965 doesn’t quite hack it compared to a design from 2010 in terms of FAI..
