That 2 pole generator is meant for single cylinder gas engines screaming at 3600 RPM. Larger generators are 4 pole so they can turn at 1800 RPM for 60Hz and 1500 for 50Hz. And 5500W is not powerful IMO. That is a standard portable gas generator head. The car engine is way overpowered and likely not operating near efficiency. [] AC motor or generator speed: RPM = 120f/p, where f is in Hz, p is number of poles.
