As most already know, Echo USA does not reveal horsepowers for there various saw. Since I own a couple I was curious so I found this from the Yamabiko Japan site, so I consider this the best source:
(values converted from KW -factor 1.34102209)
cs-370 (36cc)= 1.88 hp
cs-500 (50cc)= 2.82 hp
cs-600 (59cc)= 4.02 hp
cs-680 (67cc)= 4.43 hp
cs-8000 (81cc)= 5.23 hp
Yes, these are a bit lower than Stihl and Husqvarna (and Efco), but I still love mine anyway, and they should last me until they pry them from my cold dead hands.
Here's the Husqvarna 281xp:
Engine specification Cylinder displacement 80.7 cm³ / 4.9 cu.inch
Power output 4.2 kW / 5.7 hp
Here's the Efco MT8200
Specifications:
Power/Displacement 6.0 HP/80.7 cc
