I don't know too much about weight, but it seems that VW 2180cc engines are good choices for lots of light sports needing 60-70hp. It seems like the people getting more than that do so by turning small props at higher RPMs.
Could 2 2180cc engines be coupled at the crank and have their carbs and timing synced up to raise their output at lower RPM? If this were to be done, would total weight be competitive for horsepower at 2400-2700 RPMs? Would it be better to couple the cranks at 90 or 180 degrees? (I would think 90 would run smoother, but don't see any obvious detraction to use 180 for simplicity)
Still love the power to weight of the Mazda Remedies, but prop reduction units are a turn off to someone without easy access to a respectable machine shop. Wanting to examine direct drive options for a while.
Thanks.
