Thank you Kachi for finding and posting the drawings of the 163D.
It appears, from the drawings, that the radiator is in front. Could there be a benefit from aero perspective in putting the radiator in the rear (NACA intake in front of the rear wheels or along the rear roofline for example) with the air exiting together with the exhaust? Or does it make no difference either way?
A smaller (than V8) engine would probably have lower cooling requirements too (resulting in a smaller radiator).
