While a typical sporty commuter car like the 2024 Volkswagen Jetta GLI has a turbocharged four-cylinder engine that produces 228 horsepower, the Proline Racing raised-cam hemi can make more than 5,000 horsepower when supplemented with available turbochargers. That’s about five times as powerful as the Chevy Performance 632/1000 engine that powers the 2023 COPO Camaro. As you might imagine, 5,000 horses don’t come cheaply. The Proline 564 cubic inch raised cam, raised port engine shows above is listed on Proline’s website for $82,500.
For that massive pile of nickels you get a freshly rebuilt engine with new pistons and rings, connecting rods, and titanium valves, plus a new wet sump oiling system. Proline will also throw in 16 FuelTech 720 pound per hour injectors and two 105 millimeter throttle bodies with a Y adapter to mount them. If you’re not prepared to spend quite that much on a racing engine, Proline also has a used 548 cubic inch hemi available for $49,900.
