A comparison of the Saturn V's F-1 and Kuznetsov's NK-45 indicates the higher performance of the NK-45:
Chamber pressure: F-1: 70 atm - vs - NK-45: 150 atm
Vacuum specific impulse: F-1: 304 sec - vs - NK-45: 331 sec
Ground specific impulse: F-1: 266 sec - vs - NK-45: 294 sec
But Kuznetsov, experienced only in development of aircraft engines, was applying methods used for development of aircraft turbines to rocket engines. These were considered not appropriate for rocket engines, and Mishin sent experts from OKB-1 to provided advice. On the other hand Kuznetsov was used to having to squeeze out all possible weight from engines, since his turbines were used on long-range strategic bombers.
