    A/F question...

    I'm about to test my turbo setup, and I want to do it right

    What should my A/F be? What is rich and what is lean?

    I'm using a LM1...


    Thanks

    Is the higher numbers going lean or rich? When is it dangerous lean?

    Higher numbers is lean. It all depends of how much boost you are running but at over 12lbs you want to be at 12.0 or less, at 20lbs closer to 11.7.
    A stock engine with factory boost is probably safe at 13.0 but with a turbo it will not last long at that AF ratio.
