[GH85Carrera]

The Allison V-1710 aircraft engine designed and produced by the Allison Engine Company was the only US-developed V-12 liquid-cooled engine to see service during World War II. Versions with a turbocharger gave excellent performance at high altitude in the twin-engine Lockheed P-38 Lightning, and turbo-superchargers were fitted to experimental single-engine fighters with similar results.
