I found the limit of an Stock 08 Turbo, non intercooled. The head lifted at 11.4 psi. The failure point was in the rear of cylinders 2 and 3, top side of head gasket. Would blow out rad overflow. NO damage to head, valves or pistons. A/F 11.5, VP C16 fuel, no timing retard, 2ndary injector RCC kit Full Pipe
Turn it down to 7psi, no leakage out rad overflow.... Studs stretching..
Cure will be, ARP Studs & nuts & washer kit, .080" spacer, Cometics MLS gasket,
APE adjustable gear.
