Dodge Challenger Hellacious Hemi Kenne Bell Supercharger
|
11. Assembled and installed in the Challenger, the supercharged stroker was equipped with a set of 80-pound injectors, dual 255 ltrs/hr fuel pumps augmented Kenne Bell 17V Boost-a-Pumps and a 3.375/7.5-inch pulley set up. The fuel system upgrade included 80-pound injectors (spacers were used to mount the rails with these taller injectors), and a pair of 255 ltr/hr in-tank fuel pumps. The flow rate of the pumps was further augmented by increasing the supply voltage to them from 12-13 volts to 17 volts. Pump flow is a function of pump size, speed, and head pressure. Increasing the supply voltage to the pump increases the pump speed, which in turn increases the flow rate. The stock injectors flows 35 lb/hr at 58 psi, and will not support the power level of the supercharged stroker. The fuel lines were also replaced with -6 lines and AN fittings to ensure adequate flow. View Related Article
