If you know peters work, you will see from the graph that it is showing 270 at the flywheel, i have also heard from the horses mouth that it made 270. Considering the task the engine was needed for, dont think 230 would sufice and as it has smashed the record i think that speaks for itself. Anyway wayne is very genuine guy and wouldnt entertain horsepower bollox, would just let the results speak for themselves!
