"Revolutionary 4.0L Four-Cylinder Engine Generates Over 2000 HP for Racing"
Elmer Racing has developed a turbocharged 4.0-liter four-cylinder engine called Thor, capable of producing 2,000 hp in racing trim and up to 3,000 hp for drag racing. The engine is designed to minimize weight while maximizing power output, making it ideal for weight-limited racing classes. The Thor long block weighs just 233 pounds due to its all-billet construction. Elmer Racing claims that Thor has the best power/mass ratio of any OEM circuit racing engine ever, including F1 engines. However, the engine is expensive, with a long block costing €82,000, and it is only available to qualified teams capable of choosing the right supporting components.
