An improved method and apparatus for a compression release engine retarder is disclosed. The method and apparatus are used in conjuction with a supercharged internal combustion engine fitted with a compression release engine retarder and a supercharger employing a divided volute exhaust gas turbine. A diverter valve is located between the exhaust manifold of the engine and the exhaust gas turbine. Upon actuation of the compression release engine retarder, all of the exhaust gas (or air) passing through the exhaust manifold is diverted to the portion of the divided volute of the turbine which is closest to the turbine wheel flange and, within that portion to the divided volute, to the region closest to the center of rotation of the turbine wheel.
