Well I installed the ENTIRE baffle kit with no trimming in 3 hours.
Last one on my 6 took 2 weeks.
I have not fit it to the cowl. But EVERY hole and fitting was exactly
perfect for my IO-540-c4b5 wide deck.
Im Serious. ZERO trimming.
I still have to fit the cowl and fit the governor bracket.

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.

Thanks Tom,
Speaking of the marble concern, do you think it wise to put a loose mesh in
front of the servo to avoid FOD, or would that screen become FOD due to the
high speed air rushing in? I think JH lost a jug when he ingested a nut or
bolt thru that opening.

I did. At one time, I was looking at putting some leuves (sp?) to help with
cooling and the one I got at the hardware "aviation department" store had a
wide screen in it. The mesh is about 1/4 inch square. I just use it to
protect the injector.

Listers it is a real good idea to saftey wire (.020) the screws that hold
on the butterfly valve on either johns or airflowperformace intankes.
Yes you will have to put in new screws with saftey wire holes and yes it
looks ugly ....but not nealy as ugly as a loose screw that has done custom
machine work on your engines valves and pistons.
