I finally had time to take my Jeep over to the Kenne Bell magician Adam @ST Performance. After review of the system Adam got to work. As usual Adam begins to build the tune conservatively and then started his real work. We installed the optional 8lb maggie pulley and fed the 426 Shell 91 octane and on a streetable pump gas tune Adam was able to coax 575hp/539ft lbs of torque. The actual boost was 7.9lbs which surprised us all. After adding 5 gallons of VP109 he began to build a race tune that finally yielded an impressive 613hp/582ft lbs! After he moves into his larger remodeled shop next week he is going to install larger injectors and an ATI 17% over drive which should put the street tune into the 600 mark while pushing the race tune into the mid 600's. The end result is a smooth idling, smog legal (if required) bolt on supercharger! Oh yea......and it runs liked a scaled ape! .
