One of the main benefits to water/methanol injection is the higher-octane level offered by the methanol. This gives the tuner the ability to get more aggressive with the tune for more power. Jones spent the afternoon tuning Welsh's '05 Roush, picking up some serious power and torque. When the day started, Welsh's S197 spun the rollers to the tune of 454.9 rwhp and 427.3 lb-ft of torque. With the timing adjusted for the water/methanol mix, which comes in according to boost and fuel-injector pulse, Welsh's convertible now lays down 484.1 rwhp with 484.9 lb-ft of torque, for a gain of just over 24 rwhp and just under 58 rwtq. These numbers also represent a real-world street tune. In a race tune, you can get more aggressive for maximum horsepower. View Related Article
