It’s time to take it up a notch and jump forward a few stages to the last prototype version of the supreme cylinder. A full 7 minutes of raw Rcmax power! Take a look at this 55 SUPREME. Second tank so rich and not beating on it. (This is perfectly acceptable for engine break in on a precision engine as long as she is on the rich side) https://youtu.be/XidwtlSHTT0
