P-63D over the C had a number of changes. Wing was bigger, with greater fuel tankage (168 vs. 126-128 US gals). Engine was the latest of the 2-stage supercharged V-1710s, the -109, able to run at 3200 rpm, with carburetor between the compressor stages, and with faster-turning impeller of the auxiliary S/C; water injection was also used. All of those changes gave significant boost to the hi-alt power, and indeed the P-39D was supposed to do ~450 mph at ~30000 ft (at least per Bell's figures, so discretion is advised). However, P-39D was too late for ww2; even the -C was too late for European part of ww2 to matter.P-63 section on Mike Williams' site: linkAs for the guns - I'd delete the 37mm cannon, install the 20mm belt-fed Hispano (same as on the P-38s and P-61s), keep the nose HMGs. Delete the wing guns and their ammo, use the freed volume for even more fuel.
