Technical Specifications and Enhancements

The S55 engine is renowned for its ability to handle high-boost settings, but it does have limitations that CarBahn addresses through its innovative engineering. By pinning the timing chain sprocket to the crankshaft and machining the block to accommodate a full-circle thrust main bearing, CarBahn ensures optimal performance and durability. The reduced compression ratio of 0.5 points compared to the OEM engine improves performance by allowing more fuel-air mixture and preventing ignition timing issues under increased boost pressure. This modification also reduces catalyst inlet temperatures, enhancing driveability on pump gas and ensuring emissions-legal operation.

• Pinched timing chain sprocket for enhanced performance and reliability.
• Full-circle thrust main bearing for improved durability under high-performance conditions.
• Reduced compression ratio for improved performance and emissions compliance.
