I think that my oil cooler set up is working great, but my coolant side is marginal at best in the current configuration. Tried measuring the diffuser recovery today, but have a real anomaly going on with my water manometers. Have a pitot located in the inlet and removed the static since I kept getting this 6 in of water difference which I know is too high. Moved the low pressure side back right in front of the radiator. It to read too large a number. Am getting suspicious that the pitot line someway is amplifying the prop blade wash. Will move it next time back to my snorkel plenum prior to the T/B for reference. Thin radiators may not be as great as I had hoped!
NOISE continues to be my major nemeis. Tried hanging the muffler with battery grounding strap and adding insulation to the floor and back of baggage vertical wall today. Still unmerciful in the cockpit. Will not fly to SnF unless I can get this under control.
Also have a drumming sound that I picked up this flight that I can not identify.

At the risk of embarrassing myself with a display of misunderstanding the physics of it all, should your pressure sensors be measuring dynamic pressure or static? Seems like I remember Tracy's measurement pics having foam chunks over the pressure sensors to remove the dynamic component of the pressure measurement. I couldn't remember if your setup has that (& I really don't know if it should, either).
