Is the 392 HEMI enough power, or would you still need to bolt on a supercharger? Frank’s awesome Dodge Challenger SRT8 392 was built by Missouri’s Franjo Speed. It’s powered by a supercharged 392 HEMI and rides on a lowered Hotchkis sport suspension, Whiteline sway bars, Nitto NT555 G2 tires (275/40ZR20 & 295/40ZR20), and 20x9.5/20x10.5 Grip Equipped Grudge wheels finished with Satin Black centers and Custom Dodge Redline Red outers!
