About time some sense came back to this thread in siegfried's last post. Comparing the virtues of The Star of Africa and how many P-40s he shot down is meaningless in a comparison between the two aircraft types. If Marsellaise was flying a P-40, it's likely his kill number would be the same. Aircraft type has little to do with it.

Thanks nuuuam,
The engine sometimes makes the aircraft. How would the MS.460 and DW.520 with their 860hp-920hp Hispano Suiza HS.12X engines were replaced with and engine equal to the DB601A (1100hp) and DB601A1a (1175hp)?
Consider a P.40 with a better engine; say a DB601/605? The supercharged Allison was neglected, the supercharging of the German engines however was not nearly so.
Immagine through fate Donovan Berlin was working for say Arado and instead of working for Curtiss designing the P-40 and he submits the exact same Ar 40 KatzAddler to the fighter competition powered by the Jumo 210. Things go well, nothing goes wrong. However Willy Messerscmitt argues that his Bf 109 is still faster and moreover climbs faster than the bigger Ar 40 which is important to intercept those fast French bombers which in pre radar times will be well over the border in minutes with no warning at all so the Bf 109 still wins the competition.
In a rare momment of procurement prudence Udet and Goering agree to the moderate production of the Ar 40 Katzaddler so long as it is powered by the more readily available Jumo 211 instead of the DB600 series. Our Ar 40 looks like a P-40 with an inverted engine somewhat like a Stuka nose and due to the Jumo 211 has sluggish high altitude performance but it gives away nothing at low altitude.
The battle of Britain comes. The Luftwaffe appreciates an aircraft more manouverable than the Bf 109 and Spitfire that can out roll and out dive both. Moover it has 50% more range than the Bf 109 (and 33% more than the FW 190) and so transforms the Luftwaffes abillity to escort its bombers over Britain and also to escort its transports across the Mediteranean though the aircraft often comes of second best against the fast climbing Spitfire a good pilot can use its speed to stay on top of the Hurricane and use his higher roll rate and slight abillity turn inside a Spitfire to save himself.
The Jumo 211 already has a two speed supercharger and soon in a series of steps the Jumo 211 receives a supercharger shroud, presurised cooling circuit and intercooler and is even outperforming the DB601 and DB605 at least at low altitude. The Ar 40 is providing the Luftwaffe with a long range strike fighter, doing the Job of the Me 210 when that aircraft was missing and providing close support better than the Ju 87.
The aircraft receives the DB605 which transforms its high altitude performance. Unlike Allison and the USAAF the Junkers and DB engines for the Ar 40 remain compact and installable (no long supercharger shafts or intercoolers) and receive good two speed or variable speed superchargers providing good high altitude performance. The aircraft is never slower than the Me 109 though its climb rate is less (not as bad as the P.40) it compensates with better range, roll rate and turn radious and doesn't run out of breath at altitude.
With the 1750hp DB605ASM engine, its streamlined shape which due to its larger size never accumulated the bulges of the Me 109 the Ar 40 KatzAddler achieves 422 mph (speed of P-40Q) and enters service in 1944 soon besting the Mk IX spitfires it only has the P-51 and the rare Griffon Spitfire to fear.
