Where they running peak and hold on the injectors?
What was the fuel pressure?
What was the injector duty cycle?
What timing advance and split were they running?
Did they have a bridgeport or peripheral port and scavenge a lot of air/fuel charge without burning it? (Making the Air/fuel ratio appear leaner than it really was and wasting fuel.)
I can't think of any other reasons that the injectors would be maxed out at that low of a horsepower number.

Even the online calculators (which assume a higher BSFC than a well tuned rotary has) say that 460 cc.min injectors should make 250 WHp.
