Brian's 2012 yellow Challenger R/T is definitely an attention grabber, and the R/T striping really looks fantastic. Brian knew exactly what he wanted to do to his stock 5.7L HEMI to really get the most out of it... He has seen the Arrington Performance Hi-Power 8lb supercharger kit produce great numbers time after time not to mention maintaining a superior level of reliability & drive-ability. When Brian's stock 5.7L HEMI showed up at our shop it baselined at 360RWHP and 396FTLBS of torque on our chassis dyno. With the upgrade of our 8lb supercharger kit and some JBA shorty headers this beautiful yellow 2012 Challenger made 488RWHP and 515 FTLBS of torque!
