    What would be a rough ballpark figure for compression in a modern NA nitro motor, and how high do they rev those things? Thanks.

    I must be in holiday stupor, because I cannot remember what NA stands for.

    Cr

    Depending on air, and how many parts your willing to hurt,
    between 14.5:1 & 15.5 :1

    As for rpm, burnout about 7000, first half of run around 5000, then up to about 6500 thru the eyes.
