Gunther Werks Unveils Project F-26 at The Quail, A Motorsports Gathering

Gunther Werks unveiled its first Slantnose-inspired build at The Quail, A Motorsports Gathering on Friday, Aug. 15. The company says project F-26 marks the culmination of everything it has learned since its first build, revolutionizing the turbo platform to deliver a staggering 1,000 horsepower.

Project F-26 gets its name from the aerodynamic shape of a fighter jet and its limited production of 26 units, officials stated in a press release. The F-26 takes inspiration from the iconic Porsche 935 Slantnose and the Porsche Slantnose road car, combining timeless design with Gunther Werks’ carbon-fiber process and a focus on performance.

Power & Performance of the F-26

Coated in custom metallic paint, the F-26 features a carbon-fiber high-downforce wing, new rear panels with an aggressive side intake design and a squared-off rear fender, all punctuated by a Slantnose front end. The in-house engineered carbon-fiber front end replaces the original Slantnose pop-up headlights with fixed units, enhancing airflow and reducing drag. The lightweight design results in a curb weight of only 2,700 pounds.

Power is supplied by Gunther Werks’ air-cooled twin-turbocharged 4.0-liter flat-six engine, co-developed by Rothsport Racing. It produces 1,000 horsepower and 750 lb-ft of torque and connects to a six-speed manual transmission and a limited-slip differential. Keeping the engine cool is a race-derived flat fan, which provides more than double the volume of air than a standard vertical fan, but more significantly provides even cooling to all six cylinders.

Additional upgrades include an all-new carbon-fiber airbox, a redesigned intercooler plenum and integrated blowoff valves within the intake system. The F-26 runs on high-octane ethanol with adaptive fuel mapping for standard high-octane gasoline. Lightweight carbon-fiber charge pipes feed the engine with the charged air to ensure the best response for the turbos. A custom 935-style exhaust with external wastegates gives F-26 its distinctive sound, noted the release.

Project F-26 is equipped with staggered Turbo Twist magnesium monoblock wheels, wrapped in Continental ExtremeContact Force tires, measuring 295/30R18 up front and 335/30R18 in the rear. The chassis features all-new double-wishbone front suspension, adaptive JRZ dampers, motorsport-grade ABS and advanced traction control. The rear wheelbase has been extended 1.18 inches to the rear, creating a longer wheelbase and improving the engine’s center of gravity.

The F-26 on the Inside

The interior of the F-26 features exposed carbon fiber, custom leather upholstery and Alcantara headliner accents. The steering wheel draws inspiration from the wing-angle profile of a fighter jet, while the wooden shift knob pays tribute to Porsche’s racing heritage. A contemporary dashboard combines a Porsche Classic radio with Apple CarPlay, blending vintage charm with modern convenience.

“The Slantnose is a bold icon from Porsche’s past,” says Peter Nam, founder of Gunther Werks. “The timing felt right to reimagine it with modern craftsmanship and engineering. It’s our way of bridging nostalgia with next-gen performance for the modern driver.”

Production is limited to 26 units, each tailored for the discerning driver who desires an analog, yet modern performance experience, officials stated.
