I don't think adding a pulley will affect the belt at all, it's the folks that don't take of the oil leak and wait too long to do maintenance.

Injectors? Not much. They start getting cranky above the 700+ whp mark where any degradation is a much bigger deal. To run them at 800+ whp they have to be perfect.

HPFP? We haven't seen an appreciable decrease to longevity. The latest version is fairly robust. It stands to reason that spinning it faster will have some effect on it, but we haven't seen anything meaningful. Get a new one, and run it.

Belt? Non-issue.

Cool, my hpfp has 15 k miles on it and is the latest revision, I have no issues with my current injectors but if I’m gonna go for big power I’m gonna throw in 12’s anyways
