Kenny Kouba of KAZ MotorSports tells us it's fairly common and easier to use the existing washer-fluid bottle to contain the water/methanol supply instead of the container supplied with the kit. Using the OEM tank for water/meth doesn't interfere with the operation of the windshield-washer system. The stock reservoir also has a large capacity (311/42 quarts), which extends the injection time for water/meth. Preparing the container involves draining the existing washer fluid and drilling a 71/416-inch hole in the lowest area of the reservoir. Kenny then installs the supplied fitting, and the tank is ready to serve its dual purpose. It's important to fill the reservoir with water before going live with water/meth. Trial tests of the system are part of the installation process, and wasting water is cheaper than sending methanol into the atmosphere.
Snow Performance provides two water/methanol injection nozzles with its Stage 2 MAF system. The nozzle is tapped into the bottom of the JLT cold-air system's intake tube and placed in front of the throttle body. Kenny recommends placing the nozzle farther away from the mass airflow sensor, as damage to the sensor could occur if it's subjected to residual water/meth mist in the tube. The injection system's lines are secured in the nozzle with push locks.
The high-volume pump fits perfectly inside the pocket in front of the driver-side front wheelwell. Kenny mounts ours on the backside of the bumper brace, where it will be secure and easy to adjust, if necessary.
The Boost Cooler's rate of injection is dictated by this digital variable MAF controller. The controller basically feeds off the Shelby's factory mass airflow meter, and increases or stops the flow of water/methanol (pump operation) within a preset range, in accordance with the sensor's output voltage and intake airflow. Using the two small dials incorporated in the controller, we set our start voltage at 2.9 VDC and ramped it to recognize full at 5.0 VDC.
Solid electrical connections are critical, especially the link between the mass airflow sensor and the input circuit of the system's variable mass airflow controller. Kenny solders critical wiring to ensure the bonds are permanent.
For best results, water/methanol systems depend on a 50/50 mixture of water and methanol. Snow Performance sells gallon jugs of ready-made Boost Juice (PN 40008; $24.95/case of four jugs) for enthusiasts who don't want to deal with measuring ingredients. Boost Juice is Snow Performance's mix of 49 percent methanol and 51 percent water. It's made in a controlled environment with special care to ensure the ratios are accurate to result in a high-performance water-methanol fluid formulated for use in the Boost Cooler injection system.
For those do-it-yourselfers reading this, VP Racing Fuels offers methanol by the 5-gallon drum, and it sells for about $25 at your local speed shop. While tap water is fine, we recommend distilled water, as it reduces hard water deposits left behind when the water evaporates.
