I'm ready to purchase now if the product is right. Maybe we could look at a group buy if we all decide on a similar solution?
Hey mate,

I have spoken to Pete about what would be required to fabricate a workable solution for our excessive oil temps.

We are pretty much on the same page and as I suspected an oil cooler kit comprising quality components ain't gonna' be cheap.

Unfortunately a quality core, thermostat, oil lines and fittings etc. are worth a few bucks and them some.

Pete has already priced up the key components and to be honest the money charged for the quality kits currently on the market, is not that outrageous.

However with some engineering knowhow and a few contacts in the industry I suspect Pete can fab up a kit that is top shelf, whilst retailing it at a price that will keep the Ebenezer Scrooges happy.

Other things to try, run RedLine Water Wetter in coolant & run 0W40 oil. I found changing to Castrol Edge 0W40 (LL-01) reduced my temps and warms up more quickly.

See:
Component protection (Limp Mode)
- Coolant temperature between 117C/242F and 124C/255F
- Engine oil temperature between 150C/300F and 157C/314F
- Result: The output of the air conditioning system
(up to 100%) and of the engine is reduced
Emergency
- Coolant temperature between 125C/257F and 129C/264F
- Engine oil temperature between 158C/316F and 163C/325F
- Result: The power output of the engine is reduced
(up to 90%)
Hey Ian,

that is a nice find, thanks for the info.

Where did you come by the data?

Whilst a "limp mode" may be avoided depending upon how hard the car is driven and the ambient temperature, I would NOT want to see my oil temp exceed 125 degrees Celsius and climbing, when tracking the car

Prior to my upgrades I had seen my oil temp hit 120 and change whilst sitting in heavy traffic, that is not really a concern.

Under this situation the engine is under no load, it is not being stressed and revved to 6,000 + RPM.

The Redline Water Wetter is a good product.

I have not used it personally but I have a close friend that is heavily involved in the WRX club of NSW and from all reports, it is considered a worthwhile mod.

Motul also have a similar product known as "MoCOOL".

They claim it can reduce engine water temperature by as much as 15 degrees Celsius.

Found it in another doc, but here it is again as I have a few. See attached pg 49.

Is the 1M got a bigger oil cooler than the 135i? I know it has better water cooling.

Why the 125 degrees???

I have a bottle of Redline WW sitting in wait, but switching to 0W40 has dropped my temps by 7-10 deg and I rarely see 120 deg.

Better water cooling will lead to lower oil temps. I.e. the upgraded BMW PPK cooling kit

In my defense I only claim it is outrageous based on the dudes in the states DIY's where they show you and say all this for 300, plus their time of course.

Cool. Keen to hear more - though there may be no point in Peter going through the exercise if his kits end up being more expensive that quality units already available (that are proven to fit/work with the N54 135/335 chassis). I haven't researched such kits yet...

Rather consider the PPK aux radiator kit if cooling is a concern, as water cooling will also lower oil temps. HP Autowerks also sell larger radiators.
I suspect the OE oil cooler thermostat prevents a cooler oil temp, on a significantly colder day.

The oil temp is not only influenced by the efficiency of the oil cooler, but the temperature at which the thermostat allows the engine oil to circulate throughout the cooler.

I would imagine if you had a similar 82 degrees Celsius as the one I am running, you would see a cooler oil temps on a cold winter track day.

I would not spend the money on the PPK cooling upgrade, as you are still utilising the OE radiator that has end tanks made of plastic.

IIRC the HP Autowerks rad was removed from sale, as they had issues with leaking cores, that their supplier could not sort out.

I doubt even the most "spirited" driving on the street, would come close to approximating the heat load you will see on a track.

I can confirm that the N54 turbos are both water and oil cooled, as I have had a good look at the OE snails since being removed from my car.

Gazz, you higher temps on road and lack of temp rise at the track is probably down to thermostat rating & extra cooling capacity respectively. How is your beast now?
Hey Tim,

stay tuned mate, as Pete is working on a complete 135i/335i cooling solution as we speak.

Your above explanation with regards 1M operating temps is spot on.

Hey Ian,

once again thanks for the engine cooling data.

I cannot comment on the cooling components of the 1M, perhaps Zuzu can chime in.

With respect to the 125 degrees Celsius maximum operating temperature, after speaking to Peter he suggests he would not want to see higher than 120 whilst tracking the car.

As I mentioned before, it is all well and good to hit 120 to 125 degrees Celsius, whilst sitting in heavy traffic on the commute to work.

But when you are putting huge loads on the internal components of the engine and spinning the motor to redline, you want both oil and water temps to be happy.

By that I mean they should be at a normal operating temperature and stable.

Changing your engine oil following a track day is certainly good practice, however it is of little use if excessive oil temps have lead to a spun bearing, as a result of improper lubrication.

Or you have cooked your engine due to radiator failure, following a blowout of a plastic end tank.

So the 1M's I see have a 2nd small radiator/cooler on the passenger side... is this oil or water?

From what I recall that was the location of the 135i PPK supplemental rad, I suspect that would be for water as I doubt the 1M would employ dual oil coolers.

Though I could be wrong, as I have never even seen a 1M in the flesh.

And I thought it was for oil as per the N54 performance upgrade kit. I could be wrong though...

Hey Gents,

I have had further discussions with Pete regarding the complete cooling system upgrade, that Advan Performance has in the pipeline.

As a rule of thumb they generally use Koyorad for all the Skyline radiator upgrades.

However given that the lead time required would be quite significant to get a prototype manufactured for the 1 & 3 series vehicles, we have decided to run with the same upgraded radiator I had installed prior to the "Hot Tuner Shootout".

The then "one-off" radiator was fabed up by PWR, who are very well known within Aus for their performance based cooling components.

I don't have the exact specifications of the radiator on hand, however Pete will dig those up next week.

I can tell you, that the PWR rad is a direct swap for the OE unit, as fitment is excellent and it also retains the use of the factory snap fittings.

I have had it installed on my 1'er for some time now, and I have had no issues whatsoever on the street.

More importantly the water temp during the Shootout, was as you would expect .

Here are some pics for you guys, as you can see it is most certainly a quality product, that has been manufactured to the highest of standards, Advan Performance standards.

Pricing on the complete cooling solution and specific component details to follow shortly.

Cheers,

JD.

Chaps I am assuning the oil cooler is on the back burner then? The reason I ask is that mike fro N54 has the AR cooler on special for $649.00 with Free Shipping (I expect UA only!!!) as part of the Black Friday Promo.

This is my prefered setup (well almost I would prefer a parallel setup where oil goes through both coolers but in this config they are seperate as I understand) of being in front of the radiator and price seems ok I guess.

Hey Paul,

nothing could be further from the truth.

The PWR rad is essentially the second component in the complete 135i/335i Performance cooling solution, that Advan Performance is currently developing.

I posted the above pics because the radiator is something that we can currently produce, as I have that exact rad in my 1'er.

The oil cooler is a work in progress.

Pete is sourcing the various components with regards the oil cooler as we speak.

This is what I can confirm thus far.

The oil cooler will be a Setrab core or possibly an Earl's core.

The oil lines and fittings will be sourced from Earl's Performance Products.

The thermostat will be an Earl's too, providing they can supply a thermostat that begins to open around the 82 degrees Celsius mark.

Otherwise we will run with the same thermostat that was supplied with my Stett kit.

The OE thermostat housing bypass/blanking plate will be fabed up by Pete himself, as will the various mounting brackets associated with the oil cooler.

Pete is also working on an upgraded trans cooler for all you Auto guys.

However first things first,

the complete cooling solution will be offered by Advan Performance, inclusive of fitment and all associated hardware for $2,495.00

It will comprise the complete oil cooler kit as outlined above, with exact component details forthcoming.

Obviously the PWR radiator pictured will be utilised.

Pete will also include your choice of either Redline "Waterwetter" or Motul "MoCOOL", to further aid in the heat exchange properties of the upgraded rad.

I hope to be able to post up pics of the various oil cooler components soon.

Stay tuned gents, more to follow shortly.

Cheers,

JD.
