Supercharged 650
Based on the legendary Corvette LT4 engine, the Ilmor Supercharged 650 packs a punch in a small and lightweight platform. At the heart of the engine is the Eaton R1740 TVS Supercharger, spinning up to 20,000 RPM and producing over 9 pounds of boost. Enough to create 650 horsepower and 665 lb-ft of torque.
The hand-assembled LT4 was produced by General Motors for use in high performance vehicles. In addition, the LT4 provides a robust platform for a performance marine engine. Leveraging the direct injection technology, the Ilmor engineering team harnessed its racing knowledge and heritage, specifically in today’s IndyCar engines, to tune and deliver the highest level of performance within the marine application.
Complete with a factory-backed warranty, the Supercharged 650 is the latest addition to Ilmor’s performance marine lineup.
