SEMA 2025 had its fair share of wild builds, but the absolute showstopper was Edelbrock’s Muskrat. It started life as a wrecked 2015 Tesla Model S 85D, purchased solely so the team could harvest its electronics for a separate Mustang project. But instead of scrapping the empty shell, the Edelbrock team did the unthinkable: they dropped the body onto a full tube chassis and stuffed a 565-cubic-inch, twin-turbo big-block Chevy where the batteries used to be.
The specs on this build are serious. Built using readily available parts from Edelbrock, COMP Cams, and Lunati, the engine utilizes a Mark IV architecture similar to the 555 Musi. With two HPT 78 mm ball-bearing turbos shoving 18 to 20 psi of boost through Victor 24-degree heads and a Pro-Flo XT intake, it generates roughly 1,500 horsepower. That power is routed through a TCI Turbo 400 transmission, propelling the 4,200-pound car to mid-8-second passes at 165 mph.
It wasn’t just built to park at a show; Edelbrock’s Muskrat is a legitimate drag-and-drive contender. The team recently finished the Sick Smokies event, proving the car’s durability. Since the big-block guzzles E85 at a rate of about 7 mpg, the car tows a custom trailer that acts as a rolling pit space. It carries tools, spares, and an auxiliary 75-gallon fuel tank to bridge the gap between pumps on long hauls. Surprisingly, the wide Tesla cabin makes for a comfortable cruiser, retaining factory conveniences like power windows and key fob operation, now paired with reupholstered race seats.
Looking ahead, the team is already prepping for Sick Week 2026. They plan to swap in a lighter 540-cubic-inch aluminum-block engine to lean even harder on the boost. Edelbrock’s Muskrat is the ultimate reminder that in the performance world, creativity and big-block violence win over subtlety every time.
