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.

What Is Weistec Engineering?

Based out of Orange County, California, Weistec Engineering is an industry leader in research, development, and design. While the company was only established in late 2010, founder Michael Weiss and his partner Steve Atneyel both have an impressive track record of working with some of the fastest and most powerful vehicles in the world. The duo were both engineers for major American OEM and aftermarket performance companies; Michael was involved with advanced engineering, while Steve specialized in computer calibration.

Michael Weiss and Steve Atneyel decided to branch out on their own and combine their expertise and experience. The pair were, and still remain, avid Mercedes enthusiast and realized that there was a huge gap in the market for a company dedicated to engineering state-of-the-art performance systems for cars powered by motors like the M156 and M159 AMG.
