This link provides some data concerning the D-B effort technologically - to uprate the later Bf 109 power-wise..
& specifically.. the longstanding rivalry with R-R/Spitfire..

J A W- that is food for thought. Comparisons of aircraft performance around the BoB by both sides was biased by their doctrines ... they were pretty closely matched leapfrogging each other as new marks were introduced. When I have a moment I'll revisit the specific power vs year curves of the Merlin and DB's. David Isby's Decisive Duel book certainly explains the operational viewpoints in Chapter 18 but we should continue to focus on the power to fly. I'll post a revised curve if necessary when I've studied and considered the results.

Hi Hot Breath,


the DB-609 was intended to use on Daimler-Benz DB Jager project;

Thanks but the illustrated nacelle for the DB609 that I asked about looks more like it is intended for a twin-engine aicraft, hanging under a wing.   If anything, it looks very similar to a He219 nacelle to my eye but it might just be the annular radiator that does that.

Didn't DB have a fighter project with the 609 in the nose and two contra rotating props just aft of cockpit?

 DB-612, a cylinder head engine, because it did not use "mushroom" valves but rotating discs with ports that in their turn coincided with the exhaust and intake ports of the cylinder head.
  outer gear teeth that connected with all the discs, turning at the same time in its position of correct draft. A butt without the disks and another with them installed. This system can be a variant of the famous Burt-McCollum-style sliding tube engines (without valves
