Gunther Werks, a leader in precision-engineered high-performance Porsche remastering, revealed its first Slantnose-inspired creation at The Quail, A Motorsports Gathering, on Friday, August 15. Project F-26 represents the culmination of everything the California-based company has learned since its first build, delivering a staggering 1,000 horsepower from a reimagined Turbo platform.
“The Slantnose is a bold icon from Porsche’s past,” said 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.”
Project F-26 derives its name from the aerodynamic silhouette of a fighter jet and its limited production run of 26 units, emphasizing both performance and exclusivity. Drawing visual inspiration from the iconic Porsche 935 Slantnose racing car and the rare road-going Slantnose, the F-26 combines timeless design cues with Gunther Werks’ signature carbon-fiber processes.
Its dramatic front end replaces the original pop-up headlights with fixed units, reducing drag and enhancing airflow, while a high-downforce rear wing, squared-off fenders, and aggressive side intakes complete the race-ready aesthetic. Coated in bespoke metallic paint, the F-26 tips the scales at 2,700 pounds.
Power comes from a Gunther Werks-engineered air-cooled twin-turbocharged 4.0-liter flat-six, co-developed with Rothsport Racing. Producing 1,000 horsepower and 750 lb-ft of torque, the engine pairs with a six-speed manual transmission and limited-slip differential. Cooling is handled by a race-derived flat fan, delivering more than twice the airflow of a standard vertical fan and evenly cooling all six cylinders.
Additional enhancements include a carbon-fiber airbox, redesigned intercooler plenum, integrated blowoff valves, and a 935-style exhaust with external wastegates. The F-26 runs on high-octane ethanol and adapts to premium gasoline via custom fuel mapping.
Chassis and handling are equally advanced, featuring a 30-millimeter longer rear wheelbase, double-wishbone front suspension, adaptive JRZ dampers, motorsport-grade ABS, advanced traction control, and staggered Turbo Twist magnesium monoblock wheels wrapped in Continental ExtremeContact Force tires.
Inside, the F-26 blends function with artistry: exposed carbon fiber, custom leather, Alcantara headliner accents, a fighter-jet-inspired steering wheel, and a wooden shift knob honoring Porsche’s racing heritage. The contemporary dashboard integrates a Porsche Classic radio with Apple CarPlay for a modern touch.
Production is strictly limited to 26 units, each tailored for enthusiasts seeking an analog yet cutting-edge performance experience. With its breathtaking Slantnose-inspired design, cutting-edge engineering, and extreme exclusivity, the F-26 cements itself as one of the most desirable and visually stunning reimagined performance Porsches available today.
