Hi, so i went to the dark side and bought a Laser 230 with a CS prop. I do loose rpm during acro when doing ballistic rolles and sometimes also during hesitations roles, as when doing a cuban with 2*1/4 on the way up - when i get to invered the engine can loose 4-500 rpm sometimes. At the same time I notice that oil pressure goes down to 20-30 psi. I have changed to a new Christen Valve 802 valve, i have increased the oil pressure from 60 to 75 during normal flight - but i still have the problem. I run 15w50 Oil since it has been used in the engine all the time. The oil temp is 180-210 F during acro.
Does anyone have a suggestion on what to do? Shall I just add som more STD-425 washers in the oil pressure relief valve and go for even higher oil pressure? Max is 9 washers so i can still add 2-3 more i get a bit higher pressure that way. Or would changing to 80w be an alternative?
