Default My attempt at a plenum

Here's a few shots of my plenum. This has taken forever. I hope it works well.

Default very well done

Chris - honestly I don't think you can say "attempt" at all. You solution looks absolutely superb. Very nice.

Very nice work!

The only potential gotcha I see is the amount of air you're stealing at the back of #3. I think you'll find your oil is going to run pretty cool with that monster cooler. I have Van's standard cooler with a 4" SCAT in the same location as you do, and a 2" scat for cabin heat is taken off of my #4 baffle.
My #3 CHT wanted to run hot while my oil was on the cool side. I ended up blocking about 50% of the area of the inlet with perforated aluminum. Oil temp went up 10 deg (to where it should be), and CHT went down by 25 deg.

I'm sure you have more air to work with than me, but something to think about anyway.

Paige

Very nice. The transition to the stock cowl inlets (vs. the Sam James "rings") is especially well done.

Default Very nice!!

Chris,

Very Very nice work. Did you lay up the top from the top of the cowl?

What cooler did you use and did you make the plenum for the oil cooler?

The only thing I see that could be an issue is the inlets being aluminum and mating with the glass. The engine moves and the cowl is fixed. Any insulator between the cowl and inlets?

Again, great work!!!
