Altitude de-rating of Turbocharged standby generator

[CuriousElectron]

Greetings, all
I had a question - does a turbocharged propane engine driven generator needs to be derated for high altitude? I understand the need for derating for high altitude, since the air is less dense at higher elevations and it loses its effectiveness to cool down the engine. But for turbocharged, aftercooled engine, does the same derating requirements apply as for a regular engine? Does anyone know?
Thanks,
EE

Consult the manufacturer for specific engines. De-rating info may be given in the spec sheet.

If the generator is air-cooled, there could be some de-rating of the generator required as well. As Bill said, altitude de-rating is specific to the equipment.

If the generator is air-cooled,

And most generators driven by a turbo-charged Prime Mover are air cooled.
