Default A Dan Horton question ?

How much air to feed an oil cooler. There are many comments on OT control and 13 row oil coolers. I returned my standard issue 7 row to Van and will purchase AFS 10 Row for my parallel 0360. A 10 row face area is only a 2 3/4"D supply from the plenum. A 13Row face area only equals a 3"D supply.
OK, there may be some loss in turns and friction and there is a lot of reference to 4" tubing. If you tapped the plenum with nice curved entry and supplied the cooler with a "Dave Anders" 10* divergence, how do you decide how big the hole should be in the plenum ?? Dan has talked a lot about pressure differential etc. , any suggestions would be appreciated and hopefully put a pencil to the subjective approaches referenced in the archives.
