Best guess is about 200cc. Little bit more or less depending on engine design. Displacement does not directly translate into HP.
Bad best geuss...5.0 =158cc and 190cc is a 6.75hp
190 cc. is about 5 hp.
5
3.3 HP
A 5.8 hp scooter is 60 hp.
5-7
16.38 cc=1 cu in. and depends on the effenceny of the motor.Could be from 5 cc to 32 cc per hp.
Around 4/5 hp.
5 hp
Typical new carbureted engine well tuned:1 x HP per each 25 ccso 5 hp would be 125 ccFuel injected:1 x HP per each 22 ccso 5 hp would be 110 cc
It depends on the horse-power of the engine. 220 cc would be about 8-10 HP, equivalent to a 6-8 HP electric motor. But a small petrol engine is usually not used at full power continuously, so manybe a 5 HP motor would do the job.
The flow of 5 hp motor pump is around 90 GPM.
The 176cc engines are about 5 hp; 160cc =3-4 hp 176 (foreign) 4-5 hp 205cc= 5-7 hp 250cc= 8 hp 350cc=11-13 hp
