Hmmm. I don't know didly about your Ford injectors but 650HP might be a tad
too much. Your calcs are assuming the 42lb injectors are wide-full-open for
mostly a full pull. My guess their (stock) duty cycle is quite a bit less
than that. Sure, you can put the electrons to the coils and hold them
wide-full-open, but for how long? What is the stock spec? When you are
making that Bonneville pull you are talking about minutes and not seconds as
in a street application. Can the injectors take that much current for that
long? It also appears you are using a BSFC of 0.5. That is reasonable for a
normally aspirated engine but what about a turbo set-up? If your BSFC is
closer to 0.6 your injectors are further marginalized. The point is you are
having fun, learning a lot, and have a tune-up that will accomplish your
goal with the 42lb set-up. Once you want go beyond that level...hide the
bills from the wife :-) -Elon
