As of the 13th, the Fund Raiser is currently about 30% behind last year in terms
of the number of Contributions. Yet, oddly the number of messages posted per
day is up by 10 to 20% on the average. It costs real money to run these Lists
and they are supported 100% though your Contributions during the Fund Raiser.
Won't you please take a minute right now to make your Contribution to keep

Robin,
Are you using the FM300 that it's 1/2" bigger? If so, what did you do to adapt
it?

I can attest to the beauty of Rod's RV-8. I revisited the thing 4 or 5
times during OSH just to take it all in. He is quite a builder.
Regarding the RAM air system one has to be very careful as to what you
are ordering. Deems & I have almost the exact same engine but my
injector body opening I something like 0.5" larger than Deems which can
be an issue. Also worth mentioning is the significant cowl mod to get
these units to work as intended. See Deems cowl mod as an example.
That being said with the BPE forward facing cold induction system and
RAM air we are getting something like 29" of MP in some phases of
flight. That is filtered RAM air.

Mike, I'm also using the FM300, I made a mold of the modification that I
made to my cowl and sent it to Rod he's got it and can produce a
fiberglass part to make the change to the James cowl much easier, from
my understanding he can handle either the FM200 or the FM300 with his
set-up.

I have the FM300. I was sure Deems had the FM200 as BPE told me I was
the first to get the FM300 on their builds.
I did not have to "adapt" to the larger opening because we did not use
the Bower air box. I like the box in theory and it would have definitely
made life easier in some ways but we did not want to modify the lower SJ
cowl inlet. We like the smile opening. Our solution was to build a
custom air box that turned out to be pretty simple to develop. SJ
recently sent us photos of a prototype air box but then they saw ours
and commented that they went the long way around the barn vs. our simple
solution. There is a whole air box assembly while ours uses the lower
cowl as part of the air box. Photos of our air inlet are detailed here:
http://www.painttheweb.com/rv-10/SJ_Air.htm
Note how close the front of the FM300 is to the lower cowl. As you can
see we removed the extension plate to give us additional room. The
curvature of the lower cowl comes very close to the FM300. Our design
self engages when the lower cowl is put in place. Not pictured a simple
alternate air inlet we built on top of the air box.
One thing I like abut our system is the flat high flow air filter. The
round opening is sitting right behind the filter vs. the cone style
filter that has a hard plastic face exposed to the RAM air requiring the
air to wrap around the filter and into the FM300. This is probably
insignificant but every bit helps.
BTW yesterday flying back form the painters shop:
5,500', 23.5/23.5, 187 kts.GS
