Since summer is approaching, and while some feel the oil heating is now a moot issue, others are taking a more cautious approach (and still others, like Nissan appear to be duff sitting, theoretically). I need to make some decisions here and would like the feedback of others regarding my theoretical oil cooler setup.
I know the Setrab oil cooler units (and I am familiar with Setrab products) are popular, if not a quick means of resolving the issue, but simply bolting up to an existing flange just behind the front grill opening is a bit too "Semtex" for me (theoretically
). I am considering the following:
^^^ Fluidyne Ultralite Tube-Fin Oil Cooler that was first developed for the Corvette, and now sold as several sizes. You bolt it to the front of the existing radiator versus being set-off in front as we now see from the current batch of solutions here.
Specs:
HD Ultralite Tube-Fine Cooler for 26" Radiator,
22" x 12.25" x 1", Oil Capacity 0.71 Quarts, Dry Weight 4 lbs.
NOTE 1: HD Unit has two more tubes (3" Higher).
NOTE 2: Oil Cooler dimensions do not include 1.5" brackets.
Here is Fluidyne's description:
"For maximum efficiency, the best location for any oil cooler is in front of the radiator. Fluidyne's engineers have designed an engine oil cooler that has an air to fin density maximized for oil cooling but does not restrict the air flow through the radiator!"
^^^ Mocal thermostat oil filter-to-engine sandwich plate.
Connecting all componentry will be Earl's Ultra Flex 650 Kevlar outer braided hoses with Earl's fittings. All theoretical constructive feedback welcome.
I have looked at the engine oil lubrication diagram in the Nissan 370Z Service Manual and it looks (although I have not substantiated this) like the oil temperature sending unit is taking its reading off the oil pulled for the oil pan. My concern is that the VVEL top-end is where the oil gets the hottest and where a better oil temperature reading would be beneficial. All oils breakdown at various temperatures, and the use of the 260F marker as being safe would appear correct if the oil is not exceeding this temperate for extended periods. But, if the oil is actually getting hotter than this in the top-end then I still have a concern, theoretically.
