Gents - a couple of questions regarding p= lenum design (IV-P/TSIO 550 specific)

1.  What do yo= u do about the oil door on top of the cowl?

3. What do you do for airflow on the pilots side where t= he 3rd intercooler is?

I'm definitely sold on the p= lenum idea and have a great carbon man here in STL.  Just need to figur= e out those specifics to get designing=E2=80=A6..

Tom, I loo= ked at your plenum page


where you place the poster board over the engine for a m= old shape.  I was thinking how easy that could be on the IO550 even if i= t didn't do all the fancy work up front with diffusers and so forth.  S= uch a simple piece might seal the back, two sides for perhaps 75% positive s= eal.  It would get rid of a lot of silicone strips with (what appears t= o be) reasonable effort.  Great idea.
