I do not own wither one. BUT,
I do not own wither one. BUT, I did visit the track (Drag Strip) over the weekend with my cousin who bought a 392 ScatPack to play with. He owned a 392 a couple years ago but traded it in on a V6 for his wife, better gas less $ etc, economical choice for her. Any way there were quite a few Challengers present. Only one of which was a Hellcat. My cousin was saying he really had wanted to get a Hellcat, but the price point of the 392 was too good to pass on. I told him several times that with the lower geared rear end and Racing slicks that I didn't think the Hellcat would beat him, or at least be worth the high $ difference. Well the proof was in the "pudding".
The Hellcat didn't beat any vehicle at the track that day. The first run that I watched was between Hellcat and an older vette and the hellcat got spanked. The Hellcat didn't look fast at all. My cousin had already made a pass before the Hellcat ran, so by seat of the "eyes" the Hellcat looked slower. The time screen at the end of the track wasn't working, so I couldn't tell emediatly the times. So in short after researching, the Hellcat was running about the same times as the 392 Scatpack. My Cousing put a 392 gearing in the Scatpack and Hoosier race slicks on drag wheels. He has about 20K less into the used Scatpack than he could have got a used Hellcat for. And is running average the same 1/4 mile times.
