The present application and the resultant patent provide a waste heat recovery system for recovering heat from a number of turbocharger stages. The waste heat recovery system may include a simple organic rankine cycle system and a number of charge air coolers in communication with the turbocharger stages and the simple organic rankine cycle system. The charge air coolers are positioned in a number of parallel branches of the simple organic rankine cycle system.
