Analysis

Just after takeoff, the pilot noted cylinder head temp and manifold pressure above red line and a loss of engine power. Mixture had been leaned for tkof. The engine quit when the plt closed the turbocharger wastegate. A forced landing was made upslope on 'slightly hilly terrain'. During the landing roll, the airplane collided with a manzanita bush. After the accident, the engine was inspected, but no mechanical failure or malfunction was found.
