The turbulences.
Mr. Bernoulli and his laminar flow is a pain in the a**. But he was excellent.
Punching holes can be worse than going without it.
To find this out you need a vaccum meter. It shows the difference of laminar flow between the outside and the inside. Even the shape or a protection net is influencing the flow.
We wanted to protect the surface of an oil cooler with a wire net. It turned out that the mesh was to small. it made the cooler useless.
A punched out hole is what it is a simple plain hole- it does not allow any laminar flow.
Hydraulic hoses cover a pressure of 100 up to 200bar. And they are build to resist scuffing and bending. This is the range where you should look at.
Standard hoses with 10bar burst pressure are dangerous. During the start up phase pressure can exeed 10bars with ease.
Even standard oil coolers have a burst pressure rated around 20bar.
So what hoses to look at? Just do it as the pros. Use Teflon hoses. They are oil resistant and will never fail-if you can bite the coin. They are easily more expensive than your complete oil cooler arrangement.
But it is, without a doubt, the best insurance against fail. Havn't seen any race car with rubber hoses for years.
Last question: You do use an oil cooler without thermostat?
Thats not good, because warm up is extended tremedously.
There is a reason for the water/ oil cooler- it help to reach operational temperatures quicker during warm up. This engine is very sensitive to oil.

look at bosh filters
where you installed your oil cooler?
here where i live, in the summer, enviromental temperatures are around 27º~33º C, in the hottest days raises at 37~39ºC ( is rare) , in the winter are around 14~15ºC in the coldest nights 9~10ºC ( is rare too). The oil thermostat is realy important to me?
I didnt removed the stock water/oil cooler, in such case the oil temperatures are reaching operational temperatures with same time as before.. or a bit more time....
you agree?
