Which Supercharger would you go with?

[Timmy]

I'm getting closer and closer to pulling the trigger on a supercharger. I'm curious, for those with a supercharger, and for those without but have kept up on the various supercharger threads, which SC would you go with? No need to respond with a "I'd go with a turbo." I've decided I'm not interested in a turbo at all.

In case your answer depends on the type of rig it would go in, let's use mine since I'm the one asking. 2014 JKU, 6 Speed manual (no worries of transmission programming issues.) I will eventually be putting 37" tires on and I think I'll be doing same as FerriFast and go with 4.88 gearing. I will NOT be putting on ANY other engine upgrades. No air-intake changes, no exhaust changes, nothing, SC is it. My driving is mainly city driving, highway speeds to 55-60mph when going on adventures, and occasional Interstate (75mph) driving. This is my third vehicle for fun, not a required daily driver (though I do drive it every day.)

It seems that there are three SC's right now in contention, Ripp, Magnuson and Sprintex. Here is what I've gathered from each so far...

RIPP

• Videos of owner show he seems to be passionate about making sure the SC and the tune solid. Has the mentality that "you take your family off-roading with you, you can't afford a failure or issue." Sounds like they've done the most amount of real-world testing of actual off-road trips.
• I believe they are now including an oil catch can as part of their shipments? Must have been watching and learning from forum postings (and has actually posted on JL forums.)
• Appears to produce the lowest amount of boost of the group, choosing reliability and drive-ability over outright performance.
• High Elevation pully available that produces 11 PSI instead of 8 PSI @ sea level, they don't advertise this much because they chose reliability first.
• SC does require maintenance, I believe at 100,000 miles.
• Sweet looking SC intercooler, but requires some frame modifications to fit.
• Indicates should take about 8 to 10 hours to install yourself.
• Centrifugal style SC, which has "spool up" more like a turbo.

MAGNUSON

• SC is the same one used by Audi (whom does massive R&D,) produces boost sooner and more linear.
• AEV has chosen Magnuson SC for their resale, so it potentially will be most mass-installed since Chrysler dealer network is in deep with AEV. More installs = more support going in to product.
• High Elevation pully available that produces 11 PSI instead of 8 PSI @ sea level. I believe JL tried to install this afterward and found it near impossible, so best to order with it originally?
• SC intercooler not as cool looking, but does not require frame modifications?
• SC never requires maintenance.
• SC supposedly has bypass valve that turns off almost all SC drag when not on boost.
• Indicates should take about 8 to 10 hours to install yourself.
• I've heard lots of tuning complaints about Mag SC.
• Roots style SC

SPRINTEX

• I believe I read lowest price?
• I believe I read highest boost?
• I believe I read lowest stated install time?
• Sounds like Sprintex support is really good, really fast?
• Don't know much more about Sprintex, please fill in good/bads.
• Twin Screw style SC.

[Thanks goes to Pickles for clarifying which manufacturer was which type of SC between cent, roots and twin screw.]
