If you're running a higher-compression engine or a supercharger and just can't get the pinging to go away, regardless of what fuel you're using, Snow Performance might have the solution for you. Snow's water/methanol injection lowers intake-charge temperatures through water's high latent heat of vaporization while the methanol acts as a potent octane booster, resulting in more power, and in many cases, more boost or timing.Information: Snow Performance; 866/365-2762, www.snowperformance.net
