1933 Napier-Lion & Napier Lion Aero Engine

1:8 scale drawings of the Napier-Railton race car and the its Lion engine are almost complete. The drawings are the platform for 3D printed parts and a chassis-only model .

 

Between 1933 and 1935, John Cobb’s Napier-Railton race car set a number of lap records at the Brooklands race track in the UK. In doing so he established a one lap record of 143 mph. No one beat that record before the Brooklands track was closed during WWII. The car also broke many endurance speed records.

The car was powered by a Napier Lion aircraft engine. The engine was a twelve cylinder ‘W’ arrangement of three rows of four cylinders which, in its basic form developed over 450 HP. It was the most powerful engine of is day and was used in a number of racing designs, not just for cars, but  also for planes and boats.

Napier Lion Aero Engine

The Napier Lion aero engine was the primary power source for the UK airforce from 1918 to the mid 1930s.  

Notably, versions of the Lion powered the Supermarine S.5 seaplane that won the Schneider Trophy in 1927 and, of course, powered the Napier-Railton race car.
