Injector rating x # of injectors x injector duty cycle% / Brake Specifc Fuel Comsumption
In your case of the 36# injectors:
36 x 8 x .85 (85% is the average max.) / .5 (average NA BSFC) = 489.6 hp
You can certainly run a little more than 85% duty cycle. These figures are also at 3 Bar fuel pressure. You can run a higher fuel pressure to support more power as well. Your particular engine may also have a lower BSFC that will help. Bottom line, you have enough injector for about 550 hp. Any more than that will take larger injectors. However, the throttle body is large enough to support as much as you can make NA. Hope this helps.
