Interesting discussion, I have a mildly warmed up TR4A street car. D =
cam, 87mm, .100 milled head and lightened flywheel. No oil cooler but I =
do use the larger capacity aluminum oil pan. My issue is getting the oil =
hot enough. Stock radiator with a Richard Good radiator shroud. Even at =
highway speeds my oil does not get much above 180 / 190 when ambient =
temperatures are below 75 degrees. 180 degree thermostat installed. =
Driving around town the oil never gets above 180. Ambient temperatures =
above 75 allows the oil to get to 220 at highway speeds. I guess I could =
go to a higher degree thermostat but I=E2=80=99d risk overheating in =
street traffic. I have an electric fan set to come on at 190.=20
Any suggestion on how to get the oil hotter? I run 20W/50 Brad Penn oil.

The oiling system provides a significant amount of engine cooling. It =
has been a while since I have read the statistic, but I seem to recall =
it accounts for about 40% of the engine's cooling. When I first raced =
my 1296+ Spitfire, it did not have an oil cooler, and it was =
overheating. I installed an oil cooler and never had another =
overheating issue. Maybe the oil cooler was compensating for an =
inadequate radiator, but it worked.
In my TR3 I often see oil temps over 220 deg F. When pushing it hard =
the oil will get up around 280. I have 2 oil coolers, one on each side =
of the radiator. Oil temp is measured in the pan. =20
Modern race oils can take temps over 300 deg F without a problem. Oil =
that is too cold can lead to moisture accumulations and sludge build up, =
in addition to robbing horsepower. I have heard that NASCAR engines are =
always running oil over 300 deg. So whether your engine needs a cooler =
depends on what oil temps you see on the track and if your cooling =
system needs some help. Hot oil is a good thing. Cool oil or =
excessively hot oil is not good. Joe(B)

When starting road racing (circuit racing) I had an oil cooler in my car =
just like about everyone else. The oil T=C3=82=C2=B0 was always low, =
less than 100=C3=82=C2=B0C/212=C3=82=C2=B0F. In 2010, to get my car =
nearer the minimum weight, I removed the oil cooler and I'm racing =
always without the cooler since then.
Can't say that the oil T=C3=82=C2=B0 is higher without the cooler, =
maybe a little bit, but still always lower than 100=C3=82=C2=B0C , even =
after 1 hour races. I'd like to have the oil T=C3=82=C2=B0 a bit higher! =
So I believe most Triumph TR 4 cyl cars don't need an oil cooler at =
all, maybe the oil T=C3=82=C2=B0 is remaining too low in sprint races. =
There are only 3 main bearings and 4 big end bearings to heat the oil by =
friction. Compared to a modern engine, the oil isn't heated up much by =
the distribition parts and in the cylinder head. About 80 bhp / litre is =
a lot for our old engines, but I think the modern oils have a rather =
easy life in it.
