yeah you should be able to do like 330-350rwhp on those injectors, at an 85% duty.

Lets see, looking at my handy fuel chart, 550/1300 @ 85% duty cycle is showing 405rwhp. 100% duty cycle puts it at 475rwhp.

at what bsfc? this is another arguement, but most of the fuel calculators i think are wrong on the bsfc. because they were made when everyone thought the stock ecu only did 63% injector duty, well surprise, it does like 85%+, so the bsfc on a stock fd is more like .85 than .65, so that makes my numbers lower. i find a .7-.75bsfc is more realistic than the .60-.65 that most people use.

what what fuel pressure? 37? 45? 100?

Very true. I don't know all those details. But when I compared the chart to when I dynoed my apexi kit, it was almost dead on the money for horsepower VS duty cycle.
