Good Day: A number of years ago when it was -35 F and snowing, I went through every thread I could find on the forum and averaged power gains by those that posted. This is from SEVERAL posts so the data should be kinda' sorta' realistic. The info is based on numbers from a Dynojet (non-loading) Dyno. AVERAGE REAR WHEEL POWER NUMBERS SRT-10 RAM TRUCKS- NA: 454 HP (with Common Bolt-Ons) with no power adders ROE: 485 HP PAXTON: 591 HP *The above information is for entertainment purposes only.
