I've been thinking of this lately...
So when selecting an oil filter, there are variables such as flow rate, surface area of the filter itself and line size restrictions. So when using an external oil cooler, which in theory, would work most efficiently "holding" the oil for longer, extracting more energy in its exchange - does it make sense to use the "lowest" flow rated filter that conversely meets the maximum demand of the engine? This is relative with any engine that uses oil; and that oil gets hot - not an oil cooled/water cooled issue - neither are immune and both could benefit from the most efficient set up. Many "oil filters" claim hi-volume flow rate (28 gallons per minute!) - whats that good for if my max engine oil flow rate at WOT/Max temp is 6 GPM? The obvious opposing theory is that the longer oil is contained in an engine - the hotter it gets. So what would be the perfect formula for engine temp and oil quench? What say you? Tony |

Sounds like you have a good handle on the issues involved. It would seem to me to do this most efficiently you would run an auxiliary cooling loop off of the sump tank using a separate pump and cooler independent of the pressure / scavenge pump. Has the advantage of sending un-aerated oil to the cooler for better heat xfer
Anyone know if that is standard practice in big boy race cars?? Wonder what the F1 guys do?? Haven,t seen your setup, I assume you are running a big ass fan with your BA cooler |

The "big boys" generally use Water to air heat exchangers as Dave eluded to below. The long term solution (in part) might be to do just that - the problem is my current cooling system is ideal but has no capacity to bring oil into the system. Therefore, this is not currently an option, yet. The line sizes the race teams use are equally impressive, as in massive, just to move oil through the coolers. I took a break today from this and fabricated new strike plates for the hood - a change of scenery is refreshing sometimes!
