Agree that the oil is important for engine cooling , although 40% seems a l=
ot : where could the engine oil loose all that heat, (with what medium coul=
d the oil exchange that amount of heat) especially when there is no oil coo=
ler? At the risk of being pedant : Probably oil and water are not complemen=
tary in engine cooling: the water takes away the combustion heat in the fir=
st place, the oil takes away the heat caused by friction (heat from the bea=
rings especially). If the water T=C2=B0 gets too high, the engine will boil=
and an oil radiator will not cure that. If the oil T=C2=B0 gets too hot, t=
he bearings can fail and an oil cooler is the obvious cure, not a bigger co=
olant radiator. Only to explain that I believe there is no need for an oil =
cooler with its complications if the oil T=C2=B0 is low enough without one.=

The oiling system provides a significant amount of engine cooling. It has b=
een a while since I have read the statistic, but I seem to recall it accoun=
ts for about 40% of the engine's cooling. When I first raced my 1296+ Spitf=
ire, 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 wa=
s compensating for an inadequate radiator, but it worked.=20
In my TR3 I often see oil temps over 220 deg F. When pushing it hard the oi=
l will get up around 280. I have 2 oil coolers, one on each side of the rad=
iator. 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 addi=
tion to robbing horsepower. I have heard that NASCAR engines are always run=
ning oil over 300 deg. So whether your engine needs a cooler depends on wha=
t 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=

When starting road racing (circuit racing) I had an oil cooler in my car ju=
st like about everyone else. The oil T=C3=82=C2=B0 was always low, less tha=
n 100=C3=82=C2=B0C/212=C3=82=C2=B0F. In 2010, to get my car nearer the mini=
mum weight, I removed the oil cooler and I'm racing always without the cool=
er since then.=20
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 hou=
r 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 be=
arings and 4 big end bearings to heat the oil by friction. Compared to a mo=
dern 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.=20
