As technology has advanced, so has the ability to make big horsepower with relatively small-displacement engines. With superchargers and turbochargers becoming more popular, people are achieving power levels with their street cars that were once only found in the racing community. This growth in horsepower, coupled with gasoline restrictions and lower octane, has forced many people to run some form of race gas to prevent engine failures. But what if you want to run on pump gas?
Water/methanol injection has become a viable option for anyone who wants to make big power on pump gas, and Snow Performance is one of the best at it. Combining a blend of water and methanol is a great way to increase octane and cool the intake charge at the same time, and doing so offers the ability to increase ignition timing, which can greatly increase power.
The Stage 3 kit from Snow Performance comes with everything needed to start your alcohol a
Snow Performance's Boost Cooler systems have been around for nine years, and the line has grown with the consumer's need for more power and better operation. Snow's newest kit for the S197 Mustang brings significant advancements, providing precise control, smoother delivery, and more power in both forced induction and naturally aspirated applications.
Snow's Stage 3 kit (PN 20130) is simple to install, and will make a significant difference in power and inlet air temperature (IAT) for around $600. The Stage 3 kit offers the most advanced controller the company has ever offered. It also acts as a stand-alone controller, making on-the-fly tuning (of the water/methanol kit) a breeze, without the use of a laptop computer or other tuning aids. The LCD-screen, dash-mounted module displays boost, EFI information, and water/methanol injection levels in real time.

"This controller is important because it doesn't just run off boost," explains Matt Snow, owner of Snow Performance. "It can run off fuel-injector pulse width or it can run off boost, making it ideal for a wide range of applications.
"The great part is it can be set up to 90-percent off boost and 10-percent off fuel-injector pulse, or any other combination to accommodate the application. With the controller, you have infinite adjustability within the tuning parameters (boost and fuel-injector pulse width)."

The rest of the kit includes Snow's ultra-high-output (UHO) pump; two nozzle sizes (375- and 625-ml/min), which allow the kit to work with combinations up to about 650 rwhp; and all the connections and fitting to use the windshield-washer reservoir tank in place of the traditional tank. Additional options include a dual-nozzle kit, 2.5-gallon tank, solenoid upgrades, and a low-level indicator.
To tackle the installation of Snow Performance's Stage 3 kit, we headed to Blow-By Racing in Boca Raton, Florida. Our test vehicle is an '05 Roush Stage 1 convertible owned by John Welsh. In John's quest for more power, he has installed a 2.6 Kenne Bell Twin Screw supercharger making 10 psi of boost to seriously raise the fun factor. This also makes his S197 the perfect candidate for a little alcohol.
