In the Lyco handbook performance charts there is always an area labelled 'Limiting Manifold pressure for Continuous Operation', at about 29"MP and a little lower at high revs.
Is this just relating to detonation? If so I would have thought the area would be labelled 'avoid' since you just don't want to go in there. Or is there another reason? Longevity? I realise I trespass there on every takeoff though no sign of detonation on the instrument logs.
Another question. Does anyone routinely operate down at around 2000rpm & 24"? I feel uncomfortable going there, though it is well inside the Lyco chart. I run well over square, usually 2050 and 22.5", but not that far. I would be interested in their experience. At my setting it is very economical.
I am running an O-320 160hp with P-mags.
Thanks
