That is a very nice cooling setup.
In our application, max power/component life was the goal, so we intentionally separated the block cooling from component cooling. We would cool everything independently with the goal of not introducing more heat into the block coolant so we could use way less water pump speed to do the same job..... Free power. One of the advantages (among many), was the tendency to avoid runaway coolant temps. Once the engine got above it's ideal temp there would be a "saturation" problem where everything overheated when we relied on engine coolant for everything.
Obviously we went through some details during the engine build to maximize power with lighter oil. Like I said earlier, the oil temps were designed to stay at 190°, and the coolant temp was 230°(yes,that was intentional).
I am curious about the "cold oil" statements....Have any of you guys had some sort of problem/experience with oil not heating once you adjusted the weight? I had heard guys say it, but had always written it off as "magazine theory", much like the 75% I/E flow theory. I honestly never ran into that condition, and really thought we had carried oil cooling to the most extreme level. Keeping in mind that we used piston squirters, so our oil may have came to temp quicker than some
