I pulled this from another of my threads:
well, since I have an Accusump with a REAL gauge, I can provide you even more info.
BONE STOCK:
-Idle (cold) 55 PSI
-Idle (hot) 40 PSI
-Cruise (~2500 RPM) 50 PSI
W/ACR Adaptor and Accusump
-Idle (cold) 60 PSI
-Idle (hot) 45 PSI
-Cruise (~2500 RPM) 55 PSI
W/ACR Adaptor, Accusump, and cooling mods-(minus 180 T-stat)
-Idle (cold) 65 PSI
-Idle (hot) 45 PSI
-Cruise (~2500 RPM) ~62 PSI. (I expect a solid 65 W/the 180)
All these readings are from the interior gauge. My true gauge on the Sump shows that I am ACTUALLY making 65 cold idle, 60 Hot Idle, and nearing 72 at 2.5K RPM (readings taken during ACR Adapt. and Sump Install, so compare to column 2)
