Part of the problem is that Germany lacked enough of the required raw materials to make it, but the turbo had technical problems:How would the Hirth 9-2281 turbocharger work without it?

The turbocharger scheme had some similarities to that on the US Republic P-47 Thunderbolt but wasn't as clean, resulting in a large assembly on the belly that gave the type the nickname "Kangaruh (Kangaroo)", since it suggested a kangaroo's pouch. The program was finally abandoned in the fall of 1943, the turbocharger systems having proved unreliable.
This though is what I mean by a clean FW190C:
The latter was to be pressurized and armed with 2xMG152/20 in the roots of wings and 2xMG131 with cap. The V16 prototype equipped with a compressor Daimler Benz "standard G" was tested in Langenhagen at the end of November 1942 and immediately gave satisfaction from the point of view of the performances. It went up to 12200 meters with a climbing speed of 22 m/s and reached 724 Km/h in smooth configuration with 7000 meters. Although promising, these performances were declared unsatisfactory for Technische Amt which suddenly claimed a practical ceiling of 13700 meters.
The GM-1 equipped versions outperformed the turbo-charged ones.
