6000 rpm is 13.69 on my graph. on standard fpr. so thats 68.45% dutycycle and im 480 hp. so in theory 100% dutycycle would be 700 hp.
although im not making 480 hp at 6000 rpm thats at 7500 rpm. im making 360 hp at 6000 rpm. can it be equaded like that or am i talking shit

Where do you make max torque?

There are pictures from the mentioned injectors. I had those Delphi/MSD/Rochester 95Lb/hr injectors and they were crap when I had them tested. Huge differences. From set of 8 injectors I had two sets that were little bit better but still not good. They do have quite good spray pattern, but the best spray pattern should be in those narrow body 600cc siemens which have 4-holes. The lesson for me was, that I won't put any injectors into my engine that haven't been flowtested.
