At SEMA 2025, Edelbrock’s standout creation was the “Muskrat,” which originated from a wrecked 2015 Tesla Model S 85D. Initially purchased for its electronics for a Mustang project, the Edelbrock team transformed the empty shell by placing it on a full tube chassis and fitting a 565-cubic-inch twin-turbo big-block Chevy in place of the original batteries.

The Muskrat boasts impressive specifications, utilizing common components from Edelbrock, COMP Cams, and Lunati. The engine, based on the Mark IV architecture akin to the 555 Musi, features two HPT 78 mm ball-bearing turbos delivering 18 to 20 psi of boost through Victor 24-degree heads and a Pro-Flo XT intake, producing approximately 1,500 horsepower. This power is transmitted via a TCI Turbo 400 transmission, allowing the 4,200-pound vehicle to achieve mid-8-second runs at 165 mph.

Designed for functionality, the Muskrat isn’t just for show; it recently competed in the Sick Smokies event, showcasing its durability. It consumes E85 at around 7 mpg, necessitating a custom trailer for tools, spares, and an auxiliary 75-gallon fuel tank for long journeys. The Tesla’s spacious cabin remains comfortable, featuring factory conveniences and upgraded race seats.

Looking ahead, the team is preparing for Sick Week 2026, planning to replace the current engine with a lighter 540-cubic-inch aluminum-block variant to increase performance further. The Muskrat exemplifies creativity and power in the performance automotive world.
