Trip to SNF was a non event with oil temps leveling off at 190-200 at cruise. I have the 4" scat and will get started on that ASAP. The bigger thing that worried me was the CHT's. They are very unbalanced from side to side. cyls 1 and 3 were 316, 325, but cyl 2 was 280 and 4 was down to 243.
So, what's the proper way to push air over from the left side of the cowl? That way I can also divert more to the cooler scat. I would like to get it down to a single 9 row cooler and take off the 7 row to avoid the plumbing and complexity. I will also be fabbing up some of the cowl ramps for the top cowl while I'm in there.
