Im going to be purchasing injectors for my car, as they are about the last part I need. Im not exactly sure what the best setup would be. I was thinking 720 primary and 950 secondaries. Mods are in sig, thinking I should make close to 400 RWHP at ~16 psi (complete guess...)

 

I dont do a lot of high end work, but I believe 550/1600 is the most common setup for haltech controlled rotaries over 350hp. That's enough fuel for 500 or so at the wheels, but still small primaries that are easy to control for a smooth idle.
