Yes but the Ki 100 lost about 19mph in speed compared to the HA-140 engine. They did very well but it was also 1944-45 and not 1938-40.It would be somewhat akin to the Ki-61 to Ki-100 path one suspects, especially when one considers the engines involved.

It would take considerable rework to fit an 801 onto the He100's frame.I'm not arguing from the POV that such a BMW powered He-100 would necessarily be better. Rather, what would take in order to get the He-100 into operational service.
Agreed.What it takes is to be better than the competition in 1938-40. Not what could be done in 1944.
Using a radial means no engine mounted cannon which means jumping through hoops to get the firepower back up.
even with the cooling system taking out you only have a 156sq ft wing to put the landing gear, fuel and guns into. About 90% of the wing of the 109 and they weren't trying to put fuel in wing.
yes and the existing fuel tanks are right where you want the gun breeches to go.He 100 was already with fuel tanks in the wing.
Japanese and who ever had access to the R-1830 before the middle of 1940, are dealing with single speed superchargers. R-1830 customers in 1939-40 may have a fuel problem. Do they have 100 octane or not?Japanese, as well as people where the R-1830 was available, will probably go with HMGs in the wings. Possibly the Type 99-1 might fit for the IJN needs, to fire outside of prop disc, IJA might find the Ho-5 attractive (can be synchronized).
Yes and no, the outboard fuel tank (4 tanks were total) can be shorter so the breech can fit. Ammo can go in front of the main spar. The extra fuel tankage must go behind the pilot.yes and the existing fuel tanks are right where you want the gun breeches to go.

He 100 in Japan with a Kinsei 40 series engine in 1940-41?
Problem with the single speed superchargers on the radials is that peak power was between around 8,000ft and 12,000ft.1-speed S/Cs certainly. Availability of the 100 oct fuel was not guaranteed, though, especially for the Axis. 91-92 oct for the Japanese.
The DB 601 has got a bit more power a bit higher up and with anything close to a decent cooling system a lower drag engine installation than the radials of the time.
Great Document.Ernst Heinkel didn't received the news of defeat of the He 112 vs. Bf 109 with joy, to say at least
We can see at least two things here: he had the 109 in his sights (figuratively speaking, ofc) and he distributed tasks to his 'deputies' to find the way of making the 'Super fighter' lighter and much more aerodynamic than the 109. He was also keen to have the DB 601 powering his fighter, even if the 601 still had some time ahead itself before the series production.
Ad-hoc translation by yours truly:

His fast aircraft of note (He 280, 100, 162, 219) were with pretty small wings/wing areas - probably he over-compensatsed after the He 112 ... debacle (wrt. lucrative military contact)? Even the He 112B was given a pretty small wing after the two earlier big wing sets were used on previous versions/prototypes.Ernest may have been a bit too obsessed with speed.
He was aiming at the near target and not the future. Current thinking (early 1937)for the 109 was two mgs and single motor cannon. They could not get the motor cannon to work and there is no mention if Heinkel and the boys did either.
The He100 was simply too small (if there is such a thing) and was a dead-end for any upgrades like engines (as happened) or different weapon arrangements.
The He280's wingspan was just two feet shy of the Me262's with a comparable wing area.His fast aircraft of note (He 280, 100, 162, 219) were with pretty small wings/wing areas
