If you want real nightmare fuel, consider the fact that these aircraft only used the basic DB 603 making 1,750 hp. Consider the possibility of them using the 2,800 hp DB 603N.
Tbh more Allied superprops shouldn’t be added to the game yet, until you add superprops for Germany, Japan, and Italy.
Currently Allied nations like the US and Britain have multiple superprops that outperform all props from 5.3br to 6.3br, and adding more allied superprops without counters would exacerbate the problem even more.

That would be a good change irregardless of whether they add moresuperprops, but also I would never want to see something like a Spiteful, XP-72 or P-51H really have to fight a 262 or F-84. I just don’t think theres any semblance of balance there. Which is why i also suggest a cap.
Lord forbid a late Meteor, F-80C or SU-11 who will outrun, outpower and even outturn some of them.
