Assuming a Dynodynamics dyno, Damo's 137 rwkW motor should be putting out conservatively around 240 hp at the flywheel, using their std calculations. Probably another way to work out what power an engine is producing is to ascertain the duty cycle of the injectors. For example, assume 365 cc/min injectors running at 75 % duty cycle. That translates to 274 cc/min of flow per injector, so total flow of 1095 cc/min for a 4 cylinder engine. Using the old rule that approximately 5 cc/min equals 1 hp, this engine should be making around 219 hp at the flywheel. Some aftermarket ECUs will tell you what the injector duty cycle is. I hope this helps. Edit: My point is the numbers are actually not that unbelievable (both are within the same ball park) and easily quantifiable.
