Thanks.Not me
From what I can gather, the V7 was engined with DB 600A (sometimes referred as 600Aa - 'a' for 'ausland' - export). The 600A was outfitted with low-altitude drive for supercharger, thus probably not much of performance improvement over the examples oufitted with Jumo 210D or G.
No. That was the prototype for the He100.Was that the one with evaporative cooling?
With the DB600 the He112 is heavier by c130kg in engine weight alone, but it also gains c300HP.Not me

That book only has the data for the DB601Aa 1175HP powered He112V10.I probably have the data but will have to dig it out. My source would be William Greens 'Aircraft of the Second World War' the 10 volume set of books containing every aircraft used in WWII (well almost every one there were supposed to be more volumes that were never finished so the Bombers end with Germany and don't include countries alphabetically after that) The fighters are in vol 1-4, I think Germany is in Vol 1 I just need to dig it out.

It should be faster, but how much faster?
That book only has the data for the DB601Aa 1175HP powered He112V10.
the data he gives is 354mph at 12140 ft; 2.760 ftps climb rate; 715 m range and 31170 ft ceiling.
Good numbers, but the V7 flew earlier (1936) and suits my TL better since the Spanish Civil War makes a good starting point for a Portuguese military modernization program.
The goal is to buy a manufacturing license.As above - the gain is limited to the low altitude, where the air is thick. Thus the max speed figure will barely change, however the speed attained at low altitudes will indeed be greater. The DB 600C/D, let alone the G/H, with supercharger gearing set for higher altitudes, thus altitude power went up to 910 PS at 4000m. That is increase of some 30% over the best Jumo 210, the 210G. Produced from 1935/36 in Germany.
The DB 601A will make 1020 PS at 4-4.5 km, depending on sub-variant.
BTW - if your ALT Portugal is rich, why not just buy Merlin in late 1930s for the He 112?

Britain did sell a lot of Hurricanes in the late 30s, but not a manufacturing license for their Merlins. Heinkel was trying to sell a manufacturing license for the He112.
OTL Portugal tried to buy Spitfires and was offered Gladiators.
