I was wondering when a PT-54 runs out of efficiency?
I have pushed mine past 29psi on pump gas and alky (A little xylene too I guess) with no knock.
The car doesn't run a whole lot faster than at 27psi, so how much are the factory ported elbow and unported heads holding me back?
I can't seem to break the 116mph mark at the moment.
