? For those who fancy installing an engine designed with mogas in mind and which in theory could give better performance than the I0-390EXP. UL power are now selling their 520T, a 220 HP Turbo charged engine which will be producing 220HP at 15,000 ft. The engine weighs 269lbs with starter and alternator, so about 39lbs less than the Lycoming, i am not sure but i don't think that would upset the COG to much and 5 extra HP at sea level and 40lbs less could get your of the ground a bit quicker and you would have about 50 extra HP at 7000 ft. Whats not to like.
Cheaper Fuel
more power
a little bit lighter
The only potential issue i can see is the dimensions it length is 33.34 versus 30.7 for the EXP, width is 29.28 versus 34.25 for the EXP and height is 21.69 versus 19.35. This engine would have to be of interest to RV14 builders, i wonder if Vans would do a FWF kit for it?
