So today I got my Autometer oil pressure gauge hooked up. I also have the factory gauge, with a NOS Made In USA Echlin OP6636 sender. I'm currently running 10-30 synthetic oil. Today's temperature was about 82. I started up the engine so I could run my new Viair compressor and evaluate its performance.
On start up, my stock gauge showed a little bit above halfway, and the Autometer gauge showed about (no exact corresponding lines) 30-32 PSI at about 900 RPM. After running a bit and kicking off the fast idle, the Autometer showed 25 PSI @ 650 RPM and 180 degrees water temp.
I went back and messed around with the compressor and checked for leaks for a few minutes. Going back into the cockpit showed 195-200 degrees and about 12-13 PSI of oil pressure at 650 RPM. Revving up to 1500 RPM netted about 30 PSI.
Those of you who have aftermarket gauges, how does this compare to yours?
