That "deltic" engine just for the water pumping is incredible, I'd never seen that cylinder layout before.

Napier was on the cutting edge of certain kinds of IC engines for a long time.

https://en.wikipedia.org/wiki/Napier_Sabre (1938).

Powered the absolute monster that was the Tempest (up to the Mk 2 - they did have reliability issues they never quite solved but 3000+HP out of an engine that weighs barely more than a tonne dry will do that)

https://en.wikipedia.org/wiki/Hawker_Tempest

Was happy to see the name re-used for our upcoming fighter.

We also called the Eurofighter the Typhoon and the (WW2) Typhoon (also a Sabre engine) was the predecessor of the Tempest - it started as a re-wing of the Typhoon but enough changes where made to give it a new name.

Just a devastating superprop in its day.
