How big of fuel injectors should I get for my 7afe. I'm going to boost it around 10 psi trying to make around 200hp. Thanks guys

Stock ST205 has 245HP and is running on 540cc injectors. I know they handle safety 300HP without raising fuel pressure (so there is some space for upgrades). So engine with 22% HP more than you want has 540cc... If you lower 540cc for 22% you get 420cc. But that is just mathematic.
On my old ST-T I had installed 330cc injectors (from Ford Probe I believe) and was running 206HP. I had no issues and running it like two years. Anyway... What I know is it was not safe at all because those 330cc were running on 100% of duty cycle (to give enough fuel to those 200HP) when pushing it. Now If I had to run 200HP car and would want to be safe for 100% they are running max at 80% of duty cycle. And again using mathematics I'm somewhere around 400cc. So from two different points of view I got into range 400-420cc. How much you believe in my mathematics is up to you  .
