  1. O F.  Thanks mate for that report,  Those figure you have supplied are a bit confusing to me. Could you elaborate there.  Our CHT is J or K  ( cant remember but it is correct) and are all in C.  Pistons  1 and 3 well over 200 C in climb. They just below 200 c in cruise.  I think that the ram air ducts need more deflectors as your has.  Paul R.

      Hi,  All figures are C.  I had high figures with wrong probe types.   Suggest you check probe is reading near 100 in just boiled water.   One other thing is the air getting out Ok.  Have you got the lip on the lower cowl to create the low pressure area?  Is there a good seal round the oil cooler so no waste air entering the engine bay?  All air in should be either in through the two nostrils or via the cooler.   OF
