Like the front fender emblems, the SRT Hellcat Redeye’s intercooler mounted Hellcat logo gains red eye inserts to signify the extra 80 horses and 57 ft.-lb. versus the base SRT Hellcat. Extra grunt comes from improvements to 25 major components and a jump in boost from 11.6 to 14.5 psi. Since Dodge has stopped production of the 808- / 840-horsepower SRT Demon, the 797-horsepower SRT Hellcat Redeye is now the world’s most powerful mass-produced V8 engine.
