From the tons of dyno pulls Tom Nelson did on a 540 Procharger EFI with intercooler, 15 psi on 91 octane is about the max to make power while staying safely away from detonation. You could go a little higher with 93 octane or water/alcohol injection, but you are pushing the gaskets very hard at that point. For sizing an F1 or F1R would be a good choice.

Bruce,
Yes, I am planning on an intercooler. The truck front end will allow a fairly large one in my opinion. I am going to build a custom rad. support. I was thinking of a Ron Davis Rad/Intercooler setup, any comments? The sheet metal intake is for the wow factor, if the price factor goes too high it will get replaced with a more standard EFI manifold. I think 15 psi would be more than acceptable if it is reliable. That is the reason for the EFI, I don't want my Dad worrying about a carb tune up. I am also hoping not to have to run a cog drive, do you think it is needed at this level? If my calculations are right 15psi should be in the 900hp range taking into account power to drive the blower. What are your thoughts on the internals of this engine? I was planning a head gasket swap, my thought was cometics. Any comments? Thanks for the information.
