My P38 sound has not only a real P-38 engine/prop/supercharger sound, but the turbo-supercharger sound also. I do not believe that the P-38s flying today have active turbochargers. Turbochargers on this aircraft quite often failed, caused fires and so on, which is why most long-range PR flights in the LW period were flown with Spit XIVs.
To answer the OP, I have also got Check 6 sounds in original language to some degree. All you need is one, and then to copy that to each folder of aircraft/vehicle that uses that as a native language.
For the AHIII SPSP I will be adding a few more details and handle the Check6 files (and others) a little differently.
