Plenty of past debate about cold air intakes, but not much actual data.
I'd like to measure the intake air temperature just prior to arrival at the cylinder head. Doing so would require drilling a hole in the intake pipe, and possibly welding a bung or fitting. My 390 has a nice set of chromed pipes; I don't want to drill or weld on them.
So, anyone have a rusty old intake pipe gathering dust? Looking for cyl #1, angle valve with the tuned plenum sump, Lycoming # 78741, same as most IO360 angle valve models.
Temperature is also required for understanding intake pipe wave activity with this sump.
