Injector System for O-360 conversion
Ray Jarvis
I've ordered the O-360 from Vans which of course is a carby engine.
I intend to retrofit an Injector System.
Who's game to recommend either the Bendix System or the Airflow
Performance system.
Problem is I have to decide for the cowling intake shortly!
Any comments.

the Airflow Performance system. Really great people to work with. Don
Rivera is a real sharp guy that has faced almost every type of injector
problem which is really helpful with our homebuilt planes.

A engine built up by Lyco for FI is going to be the correct engine for FI.
However Not all 360s can be converted to FI and they are not all the same by
a long shot.
The following is a excerpt from "Same Engine Myth" at
http://www.lycoming.textron.com/support/publications/index.html
"Because of the similarity in designation, it would be easy to believe that
the 0-360-AlA and the I0-360-A1A are the same engine except that the first
engine has a carburetor and the second a fuel injection system.
Here are some features of each engine for comparison.
The 0-360-AlA has a bottom mounted updraft carburetor,
parallel valves,
8.5:1 compression ratio, and produces 180 HP.
The IO-360-AlA features a horizontal front mounted fuel injector,
angle valves,
8.7:1 compression ratio, and is rated at 200 HP.
The
I0-360-A1A also incorporates these design items which are not included in
the 0-360:
piston cooling nozzles,
stronger crankshaft,
tongue and groove connecting rods with stretch bolts,
tuned intake system,
and rotator type intake valves.
There are actually few similarities except for the 360 cubic inch
displacement."
Of course you could always buy all these goodies and install them in the
0-360, Lyco would like it if you did :o)
Or you can just slap some sort of FI on it and run it (least you could say
you got FI)!
Then you can look twice at that "Experimental logo" on the plane each time
you fly it and say "Yes, that it is"

scheme with Lycoming, which I note saves me quite a substantial
amount over a purchase via AS etc.
Actually I ordered it with a factory fitted a Unison LASAR electronic
ignition system which has been highly recommended to me as it
increases engine life as well as power output and at the same time
decreases fuel burn amongst other things. It will take something in
the order of 400+ hours before I recover my savings, however long term
it has to be beneficial taking engine life into account !!!
I ordered this engine for a number of reasons including the fact that
there is a $9,000 price difference between this engine and the
Lycoming IO-360 A1B6 which is the engine Van's also sells on an OEM
agreement with Lycoming as an optional RV 8 powerplant.
I did infact ask the people at Vans wether I could order the
IO-360 A1A (ie factory fitted Bendix Injection System) through them
and was advised that the OEM agreement only covered the O-360 A1A &
IO-360 A1B6 engines (as option for RV 8 A/C), ie the agreement doesn't
cover the IO-360 A1A powerplant.
Unfortunately this now means I must retrofit an injector system when I
receive my shipment. No big deal, except I now have the option of
Bendix, Airflow Perf'or Ellison.
I've kinda made up my mind which I will retrofit, however will check
out the options when I get to Sun'n'Fun.
I have to have a descision a few days later when I finalise the rest
of my -8 kit with the people at Van's.
To all who have responded both here and by email, I thank you for your
imput. Thats what the net and newsgroups is all about !!!!
Which one will I go for, well I'll let you know hen I finalise as
there are a few questions for different people at SnF.

The engine you describe below is the IO-360 A1B if I am not mistaken,
then again I have been driving Gas Turbines for the last 22 years and
kinda outta touch with Lycosaurus type engines.
