Please get a fuel pressure gauge on that thing and run it at whatever speed/load is causing you problems.

We've had great success running a mostly stock cooling system with our Currie built / Kenne Bell supercharged '03 Rubicon 4.0, auto transmission, 35" BFG AT's, 4.88 gears, and Currie 4" suspension + 1" body lift. Cooling system has worked great, both rock crawling and on the highway for 14 years / 27,000 miles since the Kenne Bell SC installed.

The only cooling system upgrades we did were:

•*Flow Kooler water pump
•*Turbo City high flow thermostat
•*Mopar 7 blade fan (upgrade from stock 5 blade fan)
•*AEV Heat Reduction Hood

Exhaust system upgrades were:

•*Banks Torque Tube exhaust header
•*Borla catback exhaust

My 2’ worth suggests installing a stock radiator, shroud, and Mopar mechanical fan (7-blade if you can find one). I upgraded the cooling AND exhaust when we installed the Kenne Bell SC since I knew it would produce more heat... and haven't had cooling issues.
