Souvenirs, souvenirs ... par contre, démarrer un moteur avec un tel taux de compression avec une manivelle, j'imagine qu'il faut être le fils naturel de shwarzie et de mme flash ! (hors système à inertie évoqué par mkl).
The Pratt and Whitney R-1830 Twin Wasp engine was one of the most efficient and reliable engines of the 1930s. It was introduced in 1932 with either a 6.1 or 6.5 compression ratio and 775 or 825 horsepower respectively, at 2,400 rpm. To reach its designed power the R-1830 needed the highest octane gasoline available. Using improved fuel the R-1830 reached 1,000 hp and later 1,200 hp. It has 14 cylinders in two banks of seven. The R-1830 was used on B-24s, C-47s and the Grumman F4F-4 Wildcat, until it was phased out by Grumman. Pratt and Whitney built 13,464 R-1830-90C engines for the C-47 aircraft. It was also used in a variety of British aircraft including the Royal Air Force Catalinas, Short Sunderland Vs, Maryland bombers, and Bristol Beauforts
