Answering one outstanding question from the information I recorded yesterday, I went out this morning and logged the intake temperature again, this time with the full intake snorkel in place. The two sets of data from yesterday were made with the end of the intake removed and I thought that putting the system back to how it is supposed to be set up might make a difference. Hoping to see the intake temperatures drop 30 to 40 degrees Fahrenheit was probably too much to hope for, but it would have been nice to see some lower temperatures even if only by a small amount.
The chart below is from today and it doesn’t look much different from what I recorded yesterday.
