Google is my friend but I should have been more specific , yes just like MrOblongo said , engines names files specific to the game aircrafts .
Some of my custom engines sound files which are mix of also other than SoundMOD 093 engine files which are in question :
- Allison and Allison_tb ?
- Ha45
- M62
- M82
- Merlin and Packard Merlin sound files ? are those same or different aircraft ?
- R 2800_tb ?
- sakae ?
- vk107 ?

Thanks
