would like to know how did you dialed this piper 285 in your engine. im interested especially in overlap. im having camshaft vernier pulley so i cannot see on it when it is zero degrees on it, because it is not marked on it. at the time at TDC im having about 0,9mm inlet valve open and about 0,2mm exhaust valve open. how much overlap have you dialed at the tdc and how much boost and bhp ar you running with it? asking because i have some worries that i have dialled it wrongly and cannot reach 200bhp line with a lot of boost
