ACR 08, Oil Pressure

[Viper 55]

Compared to my 06, the 2008 ACR oil pressure runs higner at about 75-80. Anyone else experiencing the same?

 

[BennyBad]

same here, and every int. picture ive seen shows the same when car is running.

Yep, normal. The 08's have different oiling systems than the 03-06 cars.

08 has revised oil pump, scuttle valves and oil filter. Better pressure and volume.

08 has revised oil pump, scuttle valves and oil filter. Better pressure and volume.

To be extremely specific:

1. Revised Pan Baffling [pickup oriented, baffles enclosed by pickup body to prevent slosh-out]
2. Articulating Oil Pickup [dual directional]
3. Increased Oil Pickup Tube Diameter [increases pressure in tube during high demand]
4. Revised Oil Gallery Design [larger, bleeds off cavitation-causing air]
5. 120% Oil Pump Volume
6. Narrower Oil Pump Rotor, lower lobe count [speeds filling rate, prevents cavitation]
7. Shuttle Valve Cartridge Relief Valve [no pressure surging]
8. Metric Threaded Oil Filter


I spent way too much time around these oil systems for my own good...

Thanks for the response. Bottomline, based on your emails, it's operating correctly. Feel better that all is normal with the new ACR. This VCA Website can prove to be very helpful with knowledgable folks like you. Thanks again!!

Mine runs at 100 psi when I start it and then drops to about 80 psi. More pressure the better in my opinion.
