Don't take a chance on running out of fuel on a modified Hellcats. This is the original time proven voltage booster concept introduced by Kenne Bell in 1996. Used on all our supercharger kits including Hellcat Challenger & Charger. Our latest Boost-A-Pump¨ System was engineered to support the HP increases for the popular supercharged Dodges and Jeeps with both stock and aftermarket superchargers including the latest even more powerful Mammoth¨ and BIGUN¨ Kenne Bell 4.2, 4.7 and 4.9 Liquid Cooled Twin Screw kits. There is a lot of misinformation and lack of good data out there, so don't be talked into dumping the $1075 stock Hellcat fuel pump. It is the largest stock pump that we ever tested and we test a lot of fuel systems.
