Starting to fit my oil cooler and can't decide on positioning. In front of the rad' and close up to it but...
On the side with the fan behind or the other side? What do you think?
On the fan side gives longer pipes but allows more gradual bends.
There is a lot of space in the Vortx nose cone, so i fit mine underneath the radiator. That way it gets its own undisturbed flow of cool air.
Fitting a cooler on its side so it has 1 port at the top, and 1 at the bottom is meant to be the optimum mounting position for a cooler, so fit it
that way if space allows

You are quite right!
It's below and behind it :-)
The oil cooler is angled slightly back at the top to miss the rad and goes up behind it by about 5mm.

It's got to go in front but fan side or not?
How have you decided to plumb it Adi?
Non fan side.
When the fan kicks in you don't want hot air from the oil cooler being drawn through the rad.
I bet it will make little difference but that's my opinion.
Oil coolers should always be mounted in front of radiators. This is because the specific heat or amount of heat energy that water can absorb is so much greater than any other fluid. Essentially this means that the rad will expel too much heat energy for an oil cooler mounted behind it to then cool the oil sufficiently. This is why in vehicles of all kind the oil and fuel coolers are at the front, then the air con evaporator, then the radiator always at the back. I would put the oil cooler in front of the fan cooled portion as by cooling the oil when the engine is especially hot you reduce the wear damage to the oil and keep it slightly thicker which will keep cam and crank bearing clearances greater, reducing heat produced due to friction.

It will not make a blind bit of difference which side of the rad you mount it Adi....I would be tempted to mount it to one side and run a hose from the nose to it. Use something like this https://www.merlinmotorsport.co.uk/p/oil-cooler-duct-for-13-row-cooler-with-mounting-brackets-ocd13

My gut feeling and what i've done on my own cars;- 1st choice is to one side/above/below of the main rad in it's own air flow, 2nd choice is
in front of the main rad. In my mind both the oil and water cool an engine but i think looking after the oil temp/pressure is more important and
should be first in the cool air flow.

Oil pressure drop due to longer pipes is negligible. You should get more off a pressure change from the oil pump having to work harder to pump thicker (cooler) oil through the bearing clearances.
As another option, I stuck mine in a little side pod on the RH side, I was previously running a 19 row cooler behind the rad and oil temp was getting over 130 DegC on track, with a 12 row cooler in a little side pod oil never got above 98DegC even when killing it at Blyton park

I can't upload pics from my ipad but if you U2U me over an e-mail address I can e-mail some pics. It works so well out in the open air that you could easily drop down to a 9 row cooler or if you weren't using it for hard track use a 6 Row would be enough.

Having given it a good course of looking at, the best position from a packaging stand point leaves 1/2 the cooler in front of the fan.
Given that of the 3 answers to the question asked, one said in front of the fan, one said not in front of the fan and the last said it didn't
matter. So 50/50 seems like a decent compromise solotion
