Interesting autocross and drag race between the Challenger, SXT, R/T and Scat Pack models. Picking the Best Used Dodge Challenger | Engine Comparison and Drag Race!
I had a 2022 R/T (6-spd manual) before trading up to my current 2021 Widebody Scat Pack (also 6-spd manual). The R/T was really cool and the only reason I traded up was because it was a base model (which is still reasonably optioned, but lacking a few things) and I wanted a more up-scale car. Specifically, I wanted the plus package (Alcantara seats, etc.), bigger screen display, the driver convenience package (blind-spot/rear detection, HID headlights, etc.), and the technology package (auto high-beams, rain-sensitive wipers), but by the time you add all those options to an R/T, it's only a few thousand less than a Scat Pack, so I went all out and found a low-mile, one-year-older Widebody Scat Pack with all those options plus more. Anyway, there is a noticeable difference between the 6.4L and the 5.7L, but you really only feel it once the rpms get above ~4500. That's when the 6.4L becomes (as the video guy says) "breath taking". (I can only imagine what the Hellcats feel like!)
Perhaps the best value performance mod for those with the Scat Pack auto's is to do the 3.9 diff swap (that ratio found in the manual trans cars). The diff change performance improvement applies to all drive train applications.
