Performance Curve

Engine Overview:
These low profile compact design engines are ideally suited for use with a variety of equipment, including: utility carts, golf carts, and specialty vehicles that demand height requirements, as well as any other applications that require low profile mounting when height space is a premium. High power output is achieved on both models by utilizing electronic fuel injection as well as a two barrel side draft carburetor coupled with increased inlet air volume and larger venturi bore. Higher compression ratios and modified camshaft profiles produce the power when needed.

Engine Family Overview:
Featuring eight models ranging from 20.5 to 40 horsepower, the V-Twin Cylinder Series Industrial Engines are the workhorses of the Subaru commercial grade engine line. This series provides maximum versatility offering models with horizontal or vertical PTO shafts, allowing engine use with an even greater variety of industrial and construction equipment. Compared to conventional side-valve engines, Subaru’s V-Twin provides smooth, reliable torque throughout the rpm range, improved breathing room at high rpm and low fuel consumption.
