Does anyone have experience with Lycon cylinders on a O-360 with
10:1 pistions ? Any performance stats ?
Also, on a borer prop; what happens when you go from an 82/42 to
an 82/43,44,or 45 ?

Found some perfect 0-360 cyl. for measurements, (thanks). I still need a crank and block. It is for measurements for a little project so a bad, cracked crank and block is perfect maybe even a bent/bad rod, accessory case, etc. Please let me know before you throw them away. It is for education purposes. Thanks. Artic

My Smith kit cub is powered by 0-360 built by Steve Tubbs(Performance Air) /Lycon. I started with a brand new C4P Lycoming engine. Cylinders went to Lycon for port and polish, Tubbs changed pistons to 10:1 forged pistons, did a camshaft regrind, installed a advanced crank gear and custom dual exhust. Tubbs/Lycon says this combination puts out between 225 to 233hp. on Lycons dyno. It has a McCauley 1P235 prop (84/45) and ThrustLine. Cruising around Central AK at sealeval turning 2450 rpm's and no wind she makes 104mph burning 8.5 gal./hr. Does not make any diffrence if on 31's, Aerocets 2200 floats or Aero 3000 skis, it's 104mph. This is not a light Cub, but it kicks as on floats with 2 big guys and 1/2 a moose on board. This is my first and only Cub I've flown so not a lot of experience but Dave Calkens and a couple other guys have and they say its a real race horse. This is the Cub on floats featured for the month of April in the new calendar. This picture was taken in September on a trip 400 miles SW of Anchorage taking off the Ugashik River. When I left Lake Hood, loaded with rifles, shotgun, shells, fly fishing gear, waders camping gear, food, clothes etc and 48gal. in the mains and 22 gallons in the aux tanks plus 20 gallons more in the floats, it blasted off with no problem and went non stop to the cabin. I couldn't be happier with its performance.

Happy New Year!
