I have written in my Stihl 051 AV electronic Owner\'s manual that its horsepower is 5.8 hp at 7,000 rpm. I don\'t know if that is true for a Stihl 051 super. I have never heard of a Stihl 051 super.
87cc, 6.1 horsepower. Mine is a 1985 model.
STIHL 029 SUPER 56.5CC 3.8HP
92cc 7hp
Stihl 029 super 56.5cc 3.8hp
The Stihl 036 Pro is 61.5cc with a 34mm stroke, 48mm bore, and makes 4.6 horsepower at 9500 rpm.
51.4cc
usually the super means a slightly larger displacement
68.7cc the super is 72
77 cc
The Stihl 041 Super has a 48mm piston diameter and a stroke length of 34mm. Using the formula for the displacement of a cylinder, which is π/4 × (diameter^2) × stroke, the engine displacement calculates to approximately 64.3 cc. This means the Stihl 041 Super has a displacement of around 64 cc.

Stihl has only grudgingly ever published HP figures, for a long time they were only in the kW ratings indicative of Europe. The machine has approximately 4 HP.
