--> RV8-List message posted by: Speedy11@aol.com
I searched the archives but found only a few related topics. I am building a
RV-8A and I plan an IO-360. I currently have the scooped lower cowling
designed for the O-360. It appears to me that the scooped cowling could be
used with the IO-360 and may produce a good ram effect. Has anyone tried
this and what results were obtained? I agree the smooth cowling looks nicer,
but if I can get a good ram effect using the scooped cowling ...

Funny you should ask...I am at the same point - I ordered the
finish kit with plans for an O-360-A1A and since changed my
mind and ordered (and have since mounted) an IO-360-M1B. So,
I have the lower cowl for the A1A and have had to order the
cowl for the M1B - an expensive mistake($500 incl shipping).
I have researched this a little, and found that the scoop on
the O-360 cowl is too low relative to the front of the
throttle body to allow a reliable, unobstructed, filtered
intake, hence the "snorkel" which vans provides which
receives air from forward of cyl #2. I know of one individual
who fab'd his own ram air intake for an angled valve IO-360
out of fiberglass and it looks great. Could point you in his
direction if you want to contact me off the list. His work is
impeccable - at the cost of more hours...

I too will be mounting an IO-360 angle valve on my RV-8. I would be
interested in an alternative to the snorkel intake.

You IO-360 guys can you educate me as to why you went with a IO-360 200 hp
instead of a
IO-360 180 HP modified to 200 HP? You save 30 lbs from the front of the
plane this way.

Listers, IO 360 vs 0 360 modified to (200)hp
When I was building my RV8 and deciding on an engine, I talked to everybody
I could who was racing or into aerobatics and I received the same answer from
all of them and that is: IO360 engines breathe better and deliver more actual
power than the modified 0 360s. This answer came from guys who had tried both.
The weight penalty is well worth the actual power output gained. My own experience
racing my RV8 has confirmed the selection of the IO 360 that I have was the
right choice for both power and speed and climb. I would also suggest that
serious consideration also be given to a LIghtspeed electronic ignition.

Dick: Nice to see you on the list. You might also mention that Monty
Barrett and others have pretty much given up on non counterweighted engines
for high output with constant speed metal props. Though heavier, the
counterweighted crank offers significant advantages in addition to those
you've mentioned.
