I've been to the drag strip with an 03 hemi ram short bed, and my 5.7 rt Charger... the Charger ran easy 14.4 the ram low 15's, so even with a few extra 09 ponies, I don't think it will make up that much ground... and The Challenger 09 rt has a few more than my 06 Charger Rt... I took my 06 Charger to the drag strip to do battle with a 1970 Charger RT 440 auto, 323.. in perfect shape.. yes I smoked him... some of it was driver, some tires, some the quality of New fuel in an old Mopar
