not correctly:
1. ASh-82FNV (M-82FNV) erly (first) name ASh-82FN (M-82FN, the name ASh - Shvetsov's aircraft engine appeared later)
2. 1850hp - afterburning (n=2500, Pk=1200+-20), 1530hp - nominal (n=2400, Pk=1000+-10), 1630hp on 1500 m (n=2400, Pk=1000+-10), 1430hp on 4550 m (n=2400, Pk=1000+-10). По данным из "Авиационный мотор АШ-82ФН (описание конструкции)", Государственное Издательство Оборонной Промышленности, Москва 1947, страницы 9,10.
3. there are four La-5 planes with the ASh-82FN engine: type 39, type 41, type 43 (La-5UTI - double place training), type 45 (La-7).
Type 39 in parallel planes with M-82F and M-82FN were issued, M-82FN was established on existence.
Production M-82FN restrained slow increase in production of equipment of injection.
Type 41 (metal longeron) made only at plant No. 21, 89 planes.
Tests in НИИ ВВС КА (Scientific Research Institute Air Force) of serial planes:

afterburning was resolved to height of ~3000 m: the supercharger didn't create necessary pressure
