I've been advised to get an oil cooler which is fair enough and I've been looking at some 10 rows but someone else has said that if you've got an uprated rad then there shouldn't be a need for an oil cooler.

I've got an ally super 2 44mm core rad at the moment. I don't want to risk it over heating but i also don't want to try squeezing an oil cooler in if I don't really need one.

Again for those who aren't aware my spec is

Get an oil temp gauge and find out if you need one first.

Have a look in the show us yours section and see how many of the really powerful minis run them.

If you intend to do circuit work with it I would fit one. My n/a mini was getting sump temps of 115 degrees round combe. I have one fitted.

get it on the road with an oil temp gauge, and do 20 mins enthusiastic driving down the motorway and you should be able to tell if you need one

It's highly unlikely I'll be taking him on track, probably down the strip at Santa Pod though.

With all due respect AP, I was only asking for advice and I don't really have time to look through the Show Us Yours section for anyone with a 1380 supercharged engine with a set up alike to mine.

yes get an oil temp gauge and see if you need one like the gents state.

you optimum oil temp is 100c

if your tracking the car then maybe!

but i would not load the rad system up to cool the oil, as you will compound cooling somewhat

I run the evil suck through setup which I would guess is the worst for putting heat into the engine however I have fitted a gauge and I have never seen above 100deg... this is measured at the oil filter. I run CTV which is good for 110 deg.

I have found the choice of oil effects the temp esp if your as a high sustained rev like the motorway.

I run a supercharger and I don't care the TB is on the wrong side.

if you do decide to fit one, dont solid mount it...i did this and as a result it split. i made 2 brackets that came from the engine, so both anchored onto the same item. (so if the engine shakes the oil cooler does too) but it still split. ive not used some rubber that its mounted on and all seems fine so far.

Apologies Andy, I thought you were trying to be sarcastic. I see what you mean now.

It's looking like I don't really need one then, I know a blow through runs hotter but I assumed as I was running a much uprated rad I shouldn't need one. I think some scare mongering is going on *hehe!*

I've got a 1/8 NPT oil temperature sender as part of my digi dash kit, where would be best to mount it?

A sandwich plate on the oil filter housing, or you could get the speedo housing drilled and tapped and fit it in there.

If something is worth doing, it's worth doing half of.

Anything below 100 degrees is too low. I'd like the water to evaporate from the oil. I've ran 120 degrees which is a tad too high, but not much.
For a road going car I wouldn't fit one.

You need a temperature gauge first. not a cooler.

I've got a oil thermostat in my systerm if the cooler is needed oil flows though if it's not is doesn't best of both. Now I do less track days I might go to a smaller oil cooler.

The problems with these thermostats is that they open FAR too early. I think it's 70 degrees.

you can get a 92 c stat from mocal V, but this iwould still be to cool for you

You need a temperature gauge first. not a cooler.


water will evaporate well below 100 degrees. Its all to do with Gas Pressures. A content of disolved water vapour is always pressent, but as the oil heats up, it drives off that moisture. Next time you brew up, look at what is happening. The water has stopped boiling (less than 100 degrees Centigrade) yet the water is still evaporating, giving off water vapour, a gas. You dry your cloths by hanging them out to dry, but the temperatures are low in relation, yet they still dry, and yet water still evaporates.

I have to dissagree (not that I am right) with the 'anything below 100 degrees is too low' theory. How many engines new or old have strict oil temperature control, You try getting even a 130hp Mini engine without an oil cooler, oil temp above 100 on a cold night. also consider oil to water oil coolers. They will cool the oil almost to the coolant temp and is a far better way of cooling the oil as the oil temp feeding the engine will be fairly constant no matter what the weather, its a heater as well as a cooler *wink* While you might be correct in that the 'ideal' oil temp is 100 degrees, in the real world, its not always feasable unless you have complex control systems and variable heat rejection systems that match the climatic and duty conditions.

I personally would like to see my oil temps nearer to 90c, keeping the viscosity that bit higher and keeping the oil away from its breakdown point with a good buffer for those extremes of conditions. No good running 110 degrees oil with an upper limit of 120 degrees, all it would need is a slight increase in ambient temp and your engine might start to suffer the black death. What is important, is a carefully controlled flow of ambient air through the crnk case with a reasonably high oil temp, such as is used with a PCV system. A gas ballast if you will.

If you really really have to fit an oil cooler, fit the smallest one you can find, use a thermostat and locate the cooler out of direct air flows. Mocal do a stat for 90 dgrees. The better option is the oil to water cooler.

Even with the cooler and a stat in the current weather conditions, on a liesurely drive, oil temps won't even get close to 90 degrees to open the stat anway and it is in the colder months that you really need the oil temps higher to reduce the condensables collecting in the oil.

Like others have said, fit a temp gauge and monitor your driving styles with oil temps. I would measure the oil temp of that which is being fed to the engine, after the pump. Sump temperture is an average temperature. I would look to fit the temp sensor into the top of the filter housing perhaps.

On the metro van, we ran the metro oil to water cooler that goes on the oil filter housing. It just made the coolant hotter and didn't cool the oil much. On a hot day it just made it so that everything was too hot. On a sustained run up the motorway at much above 70 (3.1 CWP so about 4k revs) the oil does get a bit warm.

We've since removed this for a standard filter head and both oil and water temps are much more stable, although there hasn't been any extremes of temperature to test in since.

We have an oil cooler ready to fit, but it's a last resort. Maybe when it's running a bit more power...

I'd like to fit one of these, but they are so darn expensive:

I agree with you Colin, that a water to oil heater is the best.

On my racecar, I've fitted a small oil cooler and it's NOT in the airflow at all. This reduced the temps alone by approx 15degrees. Last year I raced without one, and saw 120 degrees, which is OK with the oil I'm using, but not reccomended.

Its not the same situation as the Mini, but on the A35 I run a Saab oil cooler, mounted behind the front number plate below the bumper.The thermostat is the standard Mocal one, which I thought was 82 degrees.The oil cooler gets too hot to touch (ask Robert !) in about 5 miles of normal driving.

I like the idea of keeping my oil relatively cool when I,m thrashing, which is most of the time,and I subscribe to the Sprocket view on water evaporation, with the caveat that the engine needs to maintain normal running temps for, say, 20 mins every time it is started so as to allow the evaporation to take place.

For the record, I'm measuring before the cooler. The hottest place in the circuit.
