I NEED INFO (HELP) FOR THE DESIGN OF A EXHAUST SYSTEM FOR A RACING PLANE. THE RACER USES A 1340 PRATT AND WHITNEY RADIAL ENGINE. I AM WIDE OPEN TO CONCEPTS AND SOURCES FOR INFO.
The engine you refer to powered the T-6 series of planes and I am sure you know this. I am not familiar with the amount of space you will have or in what airframe. This link might help you with others that have modified their exhausts.
