Sepercharger removal

I got my 02 Sahara a while back. When I purchased it it was used and came with a supercharger. My goal is to get it back to a stock 4.0 inline 6. What all do I need to do?

Figure out who makes it, get some directions for install and go work backwards.

It would help if you sell me the SC at a good price!

But seriously as mentioned get install instructions and work in reverse.

Ok thanks! I would keep it on but I have heard horror stories of the SC causing a blown engine. Which I am sure you really need to drive it hard to blow it.

That supercharger will be something you'd probably learn to appreciate...especially after removing it and seeing all that extra power disappear. What I would do...and it'll be cheaper than removal as well probably...take it to a good performance shop and have them check it out to make sure it's a good quality install and then see if they can ensure it's tuned properly. I don't think there's usually much tuning associated with superchargers (as compared to a turbo), but there's probably some... just explain that you want a good, reliable tune for a daily driven Jeep that isn't going to put your motor at opposed to a race tune designed for max power/boost which could easily damage your engine if you're not careful with it.

A SC does put put stress on a motor. Most motors can handle mild amounts of boost with any issues. I totally agree with the above and have the system checked. There have been a couple SC makes for the Jeep including Kenne Bell but getting the fuel curves and computer tuning right has been an issue. A speed density system which we have as opposed to a mass air system does not adapt as well to adding on forced induction.

any super charger or turbo adds stress as it is a forced induction however if the person that had it before you just put on a base SC chances are its near or under 10 lbs of boost at wot pretty much as mentioned above pretty much all engines can handle around 8 to 12 lbs without much worry of damage as long as it is tuned correctly because the compression on the piston isn't changing enough to worry about anything other than the mentioned reliable tune you need to keep enough fuel to keep your pistons happy and not over heat them
