This is the same engine that Ben Bowlby has selected for use in the Delta Wing concept vehicle, detuned to 300 HP or so.
That's because it weighs only 163 lbs. as pictured, and his designed required the lightest weight available. If another 50 lbs was no problem, I don't see why he would have selected a $150,000 engine to make 300 HP. There are quite a number of other choices, some right off the showroom floor.
