There are many different IO540 cases, and the baffle kit comes very close to
mine, but still required some minor surgery to fit the aft pieces.

Not sure if you all were aware that Vans is now selling a baffle kit for
the IO-0540.
I received it yesterday and the new artwork that goes with a CAD design
is really amazing. I now know why the RV-10 guys love the directions.
There is no doubt this is better than any of the baffle "kits" they have
done in the past. Now I have to determine if the parts actually fit. If
they do, it will be a nice change of pace.

Russ and Jim,
I remember asking John about having "anything" roll down the intake and then
go into the injector. As much as I want every last inch of RAM air going
into the injector, I have about a 0.5 inch gap between the intake and the
"Y" valve. Therefore, any water doesn't make into the injector. Maybe this
is the reason, I have the slowest Rocket.
Water isn't the only issue here. What about a kid with a marble who just
happens to roll it in there while you are not watching? etc. etc.
Remember, I am a pilot and not a builder. :-)

Tom,
I find when I look, water runs off the cowl, along the roof of the inlet
snorkel and at the aft end of that drips right into the Y valve and then on
into the injector. It would appear, as you say, that a gap at the bottom
would be the solution but water on my bird goes right on past that! The gap
only gets the water along the floor of the intake. We're talking about
significant amounts here.
Russ
