Marv,
I wonder if it could be the carb not flowing enough fuel at WOT. I've looked
over his plane in Camarillo. He has the exact same configuration as I do,
but
takeoff CHT is some 50 degF hotter.

Posted for Bryan Wullner <vonjet@gmail.com>:

  Anybody have any ideas or advice for the following situation:

  Lancair 360 with carbed 360 (180hp) engine. 475 hours on it about. Chrome
  Cylinders. I have a Plenum cooling system and larger cowling inlets.
  (Zavatson's cowling and plenum system)
  Oil cooler is mounted at the front inlet.
  Oil wont cool in climb and will go up to 230 and probably higher if not
  stabilized. CHT's are all hot in climbs and will go to 440 no problem. Cant
  figure it out.
  Motor runs great, compression good, boroscoped fine, mag timing good. All
  leaks in plenum or baffling are sealed.
  Probes were checked out ok.

  Only thing I haven't checked is the vernotherm.

  Thanks for any advice.
  Bryan

[How big are your cooling air outlets and where are they located? Sounds
like
you're getting the cooling air in but not letting it out. Just a thought.
