MW-50 boost has never been an option for the 264.
It doesn't make sense to use MW-50 on a high altitude bomber since MW-50 only works up to full rated altitude of a given engine.
What's been proposed was the use of GM-1 (NOx injection) which would boost performance above rated altitude for about 25 minutes, however tests showed that there was no reasonable effect when using GM-1 on BMW 801 engines - even though it worked perfectly well on inline engines like DB 605 or DB 603. The germans never managed to wrap their heads around this issue. In the end it's been a simple thermal load issue of the 801 piston banks, but that's a different story...
Fact is the prototypes used various BMW 801 G-2 engines (where the G-2 is essentially a D-2 engine like it's been in use on 190s, just with a different reduction gear for larger bomber props).
The last 801 engine type fitted to Me 264 prototypes was the BMW 801 MG-2 / TC-1 ("M" for "Motoranlage", a complete engine set for bombers including some accessory installations, "G-2" is the engine type, "TC-1" is the technical upgrade status of the engine).
All proposals for the final Me 264 with 4x BMW 801 engines used the BMW 801 E engine, which is essentially a BMW G with different supercharger gear, giving a slightly higher output of 2000hp rated.
That's what we will use on this what-if mod too.
Performance figures from BMW promised some 600kph top speed @10km altitude.
Probably real life figures would be below that promised value, so we'll try to settle somewhere in the 590kph range.
