German boost systems used earlier

Have been reading a lot of topics (from Wiking mostly) about WW2 german ATL engine and aircraft developments. Also reading what i can on the www about these boost systems MW-50, GM-1, C3 extra fuel injection. It appears that while GM-1 was used in fairly limited numbers as far as i can make out as early as 1940/1941 (and was only useful at high altitude), the MW-50 was really used in numbers starting with spring 1944, all this mainly concerning the Bf-109E/F/G. The FW-190A apparently hardly used MW-50 despite what one can find in literature, but used C3 injection instead (for FW-190F at low level first, then cleared for 190A at all altitudes) starting late 1943 or early 1944, while the D-9 used MW-50. Would also be interesting to know if the Me-110, 210 and Me-410 used any of these boost systems, i seem to recall mention of some 110 versions using GM1 while the 210 apparently used something called MW1 (persumably same as MW-50). Did the Me-410 used MW-50?

Now i understand there is the issue of DB-605A and BMW-801D not even being cleared for their maximum ratings until 1943, so just curious how could they have sorted these issues earlier and start using things like MW-50 in 1942, they would certainly be of significant help. Engine life would be an issue, but hey, it's war, what's the point to try to make the engine last for longer if the plane and especially pilot will be lost against increasingly stronger opposition when you can at least save the pilot and aircraft for a bit more time (and shoot down more of the opposition in the process), if not the engine that has to be rebuild every 30 or 40 hours.

Would appreciate what the experts have to say on these little matters. Fw-190A-8 and Bf-109G-14 level of performance in 1942 would be interesting to ponder, not to mention some minor aerodynamic improvements for the Bf-109 starting with the E that i have in mind, like cleaner cowling for E and no tailplane struts (for another perhaps 20-25kph in speed), wheel covers for F/G and force the pilots to keep the tail wheel retracted as much as possible, all this gives another 15-20 kph in speed for the G. Speed is life.:)
 
I was going to answer the questions before you even asked them, but I thought I'd wait for the experts too.

You missed out on MW30, and ethanol could be used in MW50 system. Pure water was also injected, if the temp was warm enough.

The GM-1 system installed on the Ju-88S weighed 400 lbs and carried 900 lbs of nitrous, for up to 45 minutes at the slow rate.

Aerodynamic improvements to Bf-109 were called Bf-109K. The first 109s without tailplane struts had an annoying habit, losing tails.

Well, if the E without taiplane struts start losing tails they would eventually sort it like they did OTL, even before the war. Having another 20 kph in speed will alter things accordingly in regards to the Spitfire Mk I (which actually LOST speed in this period 1939-1940), not by that much but still a tangible difference.

As for the 109K and G, the difference in speed betwen K-4 and G-10 is aprox 25-30 kph, this mainly from the K having all landing gear fully closed, the rest of the airframe and engine is practically identical. Same kind of mods in 1942 on a G would also increase speed by a similar amount, even taking the lower figures circulating about, f.e. in romanian sources G-6 is credited with 623 kph, but it could go to 645-650 with just these landing gear mods, the G-2 can go from 635 to 660+, and with the MG151/20 pods from 600 to about 625-630. I would say that is a significant difference, this without even considering having MW-50 in service earlier, which can also add i dunno, 30 or more kph for both the 109G and FW-190A, not to mention increased rate of climb and acceleration.
