WATE/METHANOL INJECTION   

Water/Methanol Injection was originally used to reduce knock while increasing power and performance in aircraft engines and eventually came to be used in the motorsport industry where it was found to have substantial benefits on turbocharged engines. The Weistec Water-Methanol Injection System provides substantial cooling and knock prevention benefits for the M139 engine helping improve consistency and performance. The combination of the cooling effects of methanol and the knock resistance of water result in significant gains (through improved cooling and octane) in horsepower and torque.          


 

 

 

READY TO INSTALL      

Weistec has engineered and manufactured many of the components of this system to ensure a simple and straight forward installation that a universal kit simply lacks. This system is a complete bolt on system that can be installed without any guess work or custom fabrication. The gains in performance paired with its consistency, makes this an essential upgrade for the M139 engine.
