    No, the 603 was scheduled for the Me-209, it was too big too fit in the 109. Shame, great engine.

    DB-603 wasnt just a bigger DB-605

    it was a re-design , larger & stronger

    improvement would likely have been similer to the Griffon Rolls Royce engine over their Merlin

    DB-605s used the 603 supercharger from at least 1944 onwards

    no , they stuck the DB-603 larger supercharger on the in-production 605 for better high-alt performance but the motor was differnt to the 603 inside

    i didnt realise the DB-603 was passed around during WW2 ?

    Going by the numbers, BD 603 is a step backwards from DB 605, now is it ? LOL

    No, the Db603 was a development/redesign of the 601; the 605 was a bored out 601 when they realised they needed more power, and the Me-209 wasn't coming any time soon.

    Umm, at least there was a single Bf-109 G6 (recon variant) with Jumo 213A (thirteen) as a prototype of Bf-109L. The plane of W.Nr 410528, flew first on 12 october 1944 in Berlin-Staaken. Reportedly it was capable of achievieng 780kmh at 10km with MW50 on and 740kmh without it ("Messerschmitt Me-109 cz.3", by Robert Michulec).

    Development of the DB601. Similar in size, so that it could replace the
    DB 601 without too much modifications to the aircraft. The cylinder block
    was redesigned to increase the bore, and the permissible rpm increased.
