1978: Air-to-air charge-air cooling
March 25, 2011 | by: John Baxter
Today’s clean engines would be impossible without this remarkable device. It placed the charge-air cooler in front of the radiator and brought the air coming out of the turbo almost back down to outside temperature, cooling it more than 300 degrees. By increasing intake airflow without increasing the temperature of intake air significantly, this development further increased power output without making the engine harder to cool. Not only was performance improved, the cleanliness of combustion was substantially improved.
