Weistec Water|Methanol Injection System McLaren 540C | 570S | 570GT 16-19



Model #01-838-01871-7

Shopper Award
The Water/Methanol injection has been in use for several decades in multiple applications. Originally, it was used to reduce knock while increasing power and performance in aircraft engines. Eventually it came to be used in the motorsports industry where it was found to have substantial benefits on turbocharged engines. The Weistec Water/Methanol injection System features a Water/Methanol Controller with built in MAP sensor. This controller is a progressive controller that slowly increases injection as boost builds, resulting in smooth and seemless operation. The included Turbo Charge Pipes each have a built in bung, allowing the use of two injectors for uniform injection and cooling. The combination of the cooling effects of methanol and the knock resistance of water result in significant gains in horsepower and torque as well as reduced chance of heat soaking the intercooler system.

This system is a complete, bolt on system that can be installed with out any guess work or custom fabrication. Weistec has engineered and manufactured many of the components of this system to ensure a simple and straight forward installation. The gains in performance and consistency make this system an essential upgrade for the McLaren Twin Turbo V8 engine.
