Pump Octane ratings are measured in a special low tech test engine at cool temperatures [inside lab 72F]..........they mean nothing in a modern supercharged engine.
Simple to test, try a tank of 100+ octane unleaded racing fuel........knock goes away = fuel and compressed air temperature problem.

Well I think that is what I posted in the first post, I said either cooling IC temps, adding injection system or better octane. I understand that the engine we have is high compression so it is not really made for boosting, not like my TT car which is an 8.5.1 and boosts 21psi with no problem, just an upgraded fuel pump and larger injectors.
I just wanted to really know if our engines can handle 9psi with the stock block and if I need to worry just yet, I also wanted to know if 9-10psi was the limitation of what the stock block can handle until I drop the compression to 8.5.1 with the rebuild planned.
