I have no idea .

My intension was not max effort for sure . At this point I have no crack case evacuation , meaning I just run breathers with tennis bands around them. I really don't have room for a vacuum pump system without taking the inner fenders out . My machinist is a guy I went to high school with and is still in my home town. He went with me to my last race and really knows what im doing . I let him know that the main goal was to keep it simple . Load it , race it and put it up . I already work on it enough .
