Built to kill tires, pull donut wheelies, and put on a show, Zach Pinnock’s 2019 Polaris RZR, nicknamed Hell Razor, is no ordinary side-by-side. What started as a rough backyard LS swap was torn down to the bare frame and rebuilt with a Texas Speed 408, twin 68mm Comp turbos, a shorty Powerglide, Gen 5 Camaro rear diff, custom Porsche 930 CV axles, and sand rail hubs. Controlled by a Holley Dominator EFI system with internal data logging, MSD solid-state relays, a Holley 12.3 Pro Dash, custom Holley unterminated harness, and a Holley VR1 variable-speed fuel pump, this E85-fed monster is built to make serious power, around 900 hp once the boost gets turned up. After a last-minute thrash and help from the Holley tech team at LS Fest, Hell Razor heads straight to Burnout Wars in front of 10,000 fans to see if it can keep the rods in, the tires off, and the party alive.
