180bhp is a lot less than 280bhp but then 750cc is a lot less than 1600cc!!
Therorically if the engine was bored out to 1500cc or more likly two 750cc engines joined by a common cranshaft then the potential power output is 360bhp! from 1.5 litres. A 1.5 litre V4 2 stroke based on GP bike technolgy has the potential to produce 600bhp!! so it would blow a 1600BDA into the weeds.
