Hans, thanks for these Pics! Engine builders always amaze. This one gives you a great view of their exhaust setup with the turbocharger. Incredibly cool stuff[emoji14]

My son in law says Pratt no longer supports this engine.

Re: Decided to buy a new engine for the Z

To me the amazing part is that this is 1940's technology! At the same display they had a cutaway of a basic P&W radial engine. The supercharger was actually integral with the block (if you can call it that) with variable boost controlled via its own gear set. In other words the supercharger speed could be shifted like a manual transmission. Cool stuff...

Turbocharged AND supercharged!
Not to mention thrust from the exhaust!
