no cliff notes. ive spent some time on the head and put oversized valves valves in. running an hx35 for a turbo and cruise with 22psi on the stock rotating assembly. have had it up to 25psi with no problems. i dialed it back to 22psi to keep from spinning the tires on the highway. i have no doubt in my mind that it will hold 30psi on stock internals with the right tune and fuel. ive only ran on pump 93. some 110-112 should be sound insurance. ill figure it out one day. dont have the traction at the moment to make it worth testing at this point.
