The attached data is off a new 160hp O-320 from Aerosport Power. It is noticeable that CHT1 typically runs 15 or 20 F cooler than the average. Is this a big enough discrepancy to make it worth reducing the air hitting it to bring the temperature up a little? Is there any point? Would this have the effect of reducing the temperatures of the others?
After just 8 hrs of running is it too early to make any decisions like this?
I have been told that for break in I must keep the mixture rich. Is the reason for this just to guard the CHTs or are there additional reasons? With the CHT under control I would like to start pushing a little less fuel through the engine.
There is a super set of the data here on my blog.
