We've had this beast for years but I finally dug it out of our old hangar and brought it home. I haven't determined for sure yet but I believe it's either from a P38 Lighting WWII fighter or a B17 Bomber. Maybe I'll drop this thing in my Q45! lol, I don't even think my 4.5L V8 would even turn it!

Just thought I'd share the photos for your viewing pleasure...

 

thats f^%king awesome.. thanks for sharing. probably worth a fortune to a collector.

 

Came across this cool Army Air Force training video from WWII on operation and maintenance of this "turbosupercharger".
