http://www.raf303.org/funked/typhoon_eng.wav I use this one for the Typhoon, but it sounds good for any powerful plane.

Since there is no BMW 801 operating today, it is not possible to get a real recording. However a good choice would be the sound of an F4F Wildcat, because the BMW 801 and the Twin Wasp were both evolved from the same design. Also the Ash-82FN in the Flugwerke 190 would be a good choice. I will try to get a Wildcat recording in October.
