Additional Information

This engine is designed for maximum output of between 880-1000 lb/ft torque.

The stock engine compression ratio is relatively high due to the Corporate Average Fuel Economy (CAFE) standards which push for consistently higher fuel economy in cars and trucks. However, this increased compression limits engine performance with higher boost settings by decreasing the size of the fuel-air charge in the combustion chamber, forcing the ignition timing to retard far below MBT (mean best timing, the theoretical optimal ignition timing). Therefore, the CarBahn Autoworks S63 engine has 0.5 less compression to optimize the engine for the increased boost. In an emissions-legal street car, the lowered compression has the added benefit of reducing catalyst inlet temperatures and improved drive-ability on pump gas.
