well i was flicking the switch at 4000 rpm, but today i was allowed to go on the dyno again, and this time i flicked the switch at 3500 rpm = 171.3 kW!!!!!!!!!!!!
wooot!!!!!!!!!
and i think u might actually find that it didnt actually have anything to do with the dyno, the bottle of gas being used on friday had been siotting around for bout a year, and then i freshed it up the new gas, therefore getting a much better reading as it was fresher
