Guys,
I have about 90 hours on my 10 now and I'm still having high CHT and oil temps. I have the SJ cowl (and Plenum) which Will James built 6" cooling inlets rings and I moved my oil cooler (SW10631S) directly behind #6 cylinder. I flew yesterday late afternoon in the hot 97 degree Kansas and CHT 422 and oil temp 223.
(Barrett I0-540 275 hp (9:1), dual lightspeed, vetterman exhaust with heat muffs)
Several have suggested I cover the nose wheel slot to keep that pressure air out of the lower cowl and keep from mixing with exiting air. Also, I have seen and have pictures of Jim Smiths exit/exhaust air fairing he built on his 6 and can do something similiar for exit air.
QUESTION, Has anyone done this (built a moveable nose wheel fairing to cover the lower cowl slot) and be kind enough to post pictures?
Also, I would like to purchase a manometer to test plenum pressure air and lower cowl pressure, to be certain I have pressure differential to start with.
QUESTION, Where and Which one?
Thank you in advance for your help and input.
