Message That spec sheet is very vague and should not be referenced for ring gap. If you plan to run 20psi Id suggest a. 018-.022 for the top and a. 024-.026 for the second ring. With boost you always have to account for increased heat and expansion rates. Last thing you want is to get ring flutter or burn the seal because you have too much pressure on the rings and not enough gap to relieve the ring. Each engine is different and gaps should set according to the users power and intended use of their engine.
