I used the upper cowl ramps as part of a female mold to make fibreglas diffusers that attach to the aft edge of the upper cowling. Three screws attach each diffuser to the upper cowling. A piece of ATV inner tube goes between the aft edge of the diffuser and the front edge of the plenum. This makes a flexible and apparently relatively airtight seal between the cowling and plenum. So far I've had way more cooling than I needed, but I haven't yet tested in worst case hot day conditions.

Pictures and description here.

Default Plenum

I installed a fiberglass plenum made by Russ Kamtz of KFNL. (Step up Aviation) The plenum sets in to the Vans baffle setup. You set the plenum into position, mark the inside edges and trim the baffles to fit. Reset the plenum, mark and drill holes for the nutplates thru the plenum and baffles. Install the nutplates on the plenum. Russ uses a pair of fiberglass ramps to feed and seal the inlets. The fit and install took about 4 hours. I am pleased with performance and fit ! If you are interested in an upgrade I can put you in touch with Russ

Just finished it yesterday. Overall really happy how it turned out. It could use some more block sanding but the matt finish really hides the lows. I may still sand when painting begins but then again I look forward to flying this year.

Way too many fasteners. I'm going to do better next time.

All metal, vans baffles with a lid. Works just perfect, nice even cylinder temps after baffle and inlet dam adjustments. Stabilizes the oil cooler mounting, and has way too many fasteners to deal with. No top cowl puffing in flight. 10 kts....

Regards, Chris
