>I got water injection for the blower and wanna run 11:1 You plan on running race gas on a daily basis? I don't know how 93 octane pee water is going to hold up to that. Even with just 11:1, 93 is required!! How do you plan on tuning this properly? Hope you have some friends at a dyno shop. Remember to use a torque wrench on the main bearing caps. lee
