The most common is a bent connecting rod. If the engine is producing a sustained 1000 lb-ft of torque or more, all it takes is one knock event to bend a rod. This was taken into consideration with the ECU tuning for the W.4 Power Package as they can make far more power and torque than a stock M157 engine can handle. With our optional ECU Tune for the W.4 package, boost is controlled and tapered up to the peak of 20psi as RPM’s increase. This creates a broad torque curve that remains under 800 lb-ft (at the wheels) while allowing power to continually increase towards redline, minimizing stress on the rods as well as the rest of the drivetrain.
