My apologies for bringing back a topic that has been discussed often, but it's on my mind again. I'm sure others', too.
In my brief recent outing, my oil temps were too high (273 degrees), so I need to make improvements. I've identified areas where I can improve air flow to and from the coolers (and sealing them better), but I'm not sure that will be enough. I'm also considering changing from a single tube transmission type cooler to a "full flow" racing oil cooler.
I've gone back and reread a lot of posts. One thing that caught my attention was that many people think oil cooling is the big challenge with our cars, and that water cooling is usually not a problem.
Therefore, I'm once again considering using one VD radiator for water cooling, and the other VD radiator for oil cooling.
I know Sean O. tried a single water rad and it did not work for him, but I'm wondering if it is still a viable option. I think it would be a great way to cool the oil, but wonder if a single water rad will be enough.
As a reminder, my oil cooling is done after the dry sump's scavenge pump, so I don't need to worry about the VD radiator's pressure limits. The pressure should be pretty low since the oil would be routed from the radiator to the vented (no pressure) dry sump oil tank.
So, do you think a single, stock VD radiator will be enough for the water cooling system? The core is 20"x8"x1.5".
BTW, the intake for my VD sidepods is only 8" x 5" on each side. I may need to increase them.
Oh, another question: Does volume affect cooling effectiveness? In other words, if there is less water in the cooling system (after removing one rad and some pipe length), will the lessor volume hurt the cooling ability?
Thanks for your thoughts.
