I know the O-320/540cyl Rebel had a skytech on it. Can't remember what
Charles O-235 had on it.

As for the O-540 cylinders on an O-320, they are <supposable> giving 170+
horsepower, but I think that was an optimistic sales pitch by the engine
builder, that is no longer in the engine business (sorry B.D. but, have to
be honest here!)! Seems to perform (climb) about the same as my 150 HP
O-320, but it is just a little quicker in Cruise. I figure the engine came
out pretty similar to a high compression O-320 at 160 HP, and no more. Also
a <MUCH> heavier engine with the O-540 cylinders on there, compared to the
original O-320's, so more "teeter totter" work to do!

I am wondering if standard starters were used or perhaps an aftermarket ??

Also what do O-540 cylinders do for you on an O-320 ??

Bruce, that's what I had put on the firewall for Charles and it cranked

his

O-235 over really well. Same 6.5 to 1 compression ratio as your 0-320 will
be, if 150 HP. The Rebel I repaired this spring had an Odyssey battery ( I
think next size up) mounted way down in the tailcone and it cranked over

the

O-320 (WITH O-540 cylinders on it!!) "lickidy split"!

Someone mentioned Odyssey batteries last week, so I looked them up on a

web

page and learned the PC625, recommended battery for a Lycoming 0320, was

a

16

AH battery. The battery Gill Cell recomends for this engine is a 25 AH
battery. I like the thought of a 13lb. battery but is it large enough to

do

the job? Has anyone been using this battery on a Lycoming 0320 and what

is

your experience with it?
