Oh yeeeeeah...... now I remember. Thanks for all the good replies.
But I seem to recall a PAIR of TIO-540s ( I think they were) on a PA31 burning about 150 l/hr in the cruise. Or was that the TSIO-540 on a C402?? Or was THAT the TSIO-520?? Or was that on the C310R....???
Ah the good old days........
I DO know the C210 burnt about 60l/hr, a nice round figure, just like Elizabeth Hurley. But what engine was it??? IO-540??
