    • Dodge Demon Hemi supercharged V8 engine build time-lapse

      This is just one of those things you geek out over as a car enthusiast. Even if you are not into the Demon surely you love seeing what putting a Demon V8 together looks like. Keep in mind this is the 840 horsepower version of the Hellcat with even beefier internals.


      The Demon V8 has a larger 2.7 liter twin screw supercharger, 14.5 psi of boost vs. 11.6 psi, 6500 redline (300 rpm higher), dual stage fuel pumps, larger intake box, new block, etc.

      62% of the Demon V8 is different than the Hellcat:

      • Forged alloy steel crankshaft with 3.58-inch (90.9 mm) stroke and revised balancing
      • Induction-hardened crank bearing surfaces; individual journal optimized main bearing clearances
      • Forged high-strength alloy pistons; 30-micron increased piston to bore clearance
      • Powder forged connecting rods; upgraded shank and big end; revised ultra-high tensile fasteners
      • Flow doubled on piston cooling oil jets
      • Revised design valvesprings
      • 33 percent increase in oiling for valvesprings and rocker tips lubrication and cooling
      • Single-groove collets on valve stems for improved stability
      • Fuel injector pressure increased 27 percent
      • Oil pan and windage tray optimized for high acceleration tested up to 1.8 g
