Everyones fan would be at maximum capacity at a track day, regardless of which piggyback they were running.

Also, I would say that if you were getting the same oil temps most people get with daily commuting but out on a race track like that, then either you were driving miss daisy-style or mostly parked over on the side?

perhaps you should come to the next drive day and we can compare

The JB4 will engage the waterpump and the engine fan when the driver wants so you can activate it way before your oil temps get close to 100 to begin the cooling earlier just to give you that extra edge.

Thanks for that. Does anyone know how much the additional 1M radiator and 850w fan will cost? I could be keen.

I dont think its quite as simple as just replacing the stock fan with the 850w version. The install instructions of the ppk show that the new fan requires being hooked up to the dme, so it will require additional coding for it to work properly.

To be honest I imagine Peter would rather simply toss that "extra radiator" in the bin, than attempt to improve upon it.

He has a concept for a his 335i that would see a substantially larger primary radiator installed, but it will also require a new intercooler to be designed and fitted.

The above system would also see a supplemental trans cooler fitted up, whilst retaining the use of the OE transmission heat exchanger.

Justin, whilst I welcome the idea of a completely new radiator that replaces the stock unit, I'm not a fan of the close mesh design as it has it's downsides for a daily driver. In my case, this is my daily driver, and the occasional weekend track car so definitely a no-go for me.

Also, as you have already stated, changing out the radiator will create the need to purchase a new FMIC (which I already have and am happy with) and purchase a stand alone trans cooler. I have no doubt this would be the ultimate solution but for most it could be an overkill. Plus it sounds like big $$$. The radiator alone is $1200 or so, plus needing the FMIC and trans cooler and installation, plus the wait time to develop the product, it's just not feasible at this stage.

If you could somehow replicate and improve upon BMW's design of incorporating a secondary radiator in the brake duct, I would think it would be priced more reasonably and it might be up to the task anyway. I would welcome this idea depending on price and design.

By the way, any updates on the progress of the stage 2 oil cooler? Any photos of it installed and photos of the bracket? I hope there are not any issues?

That's a real shame. Nothing is easy on these cars!

Not off hand, you have the part numbers. Ring a BMW service centre and see how much they are

Peter and the like could get you a better deal.

Sourcing local prices is a waste of time, everyone knows prices are heavily inflated here. I'd rather not waste the dealers time chasing prices for something I will not buy from them as they are not competitively priced.

I was referring to buying from overseas. I punched in these part numbers on some vendor websites and it says 'not found'. I would have to send an email requesting the price but if someone had it handy it would save everyone some time. This isn't my next mod but it's definitely on my radar.

[1q2w3e4r]

No one is going to have pricing for them locally outside of the dealer network yet (or in the Aust forum) as I doubt anyone would have had to order a replacement one (unless someone has already punted one and a workshop has ordered a replacement).

The stock radiator retails for $190 USD just contact Turner or the like and get pricing if you are keen on it.

Thanks mate, I will look into it shortly. I thought the stock radiator would cost a lot more. If the stock radiator is in fact $190, I suspect the additional radiator is a lot less than that as it's quite small. It could be a cheap and effective solution for anyone that wants a cheap upgrade. Lets hope the 850w fan is reasonably priced too!

He means the additional radiator that is the same as the stock oil cooler and its $189 from ECS tuning. I have seen the fan for as little as $400 but you are looking at $600+ for it realistically (before shipping). Its not going to be as good as the aftermarket stuff either as none of this stuff was designed for anything other than stock power levels.

As you are in the same boat as me regarding AT, I would suggest doing the Oil cooler and then something for the ATF. Things can be done to mitigate water temps before needing to upgrade radiator but there is no way I would go back on the track without hard core cooling for the transmission as its definitely the weakest link.

I mean the OEM radiator (part no 17117558480) retails for $190 USD plus shipping.

Agreed, towards the end of the day at my last track day I felt like the transmission was the weak point also. Something will definitely need to be done but I thought it was something else at the time and put it down to overheating and possibly bad fuel. How much do you think a stand alone trans cooler will cost? I would also like something aftermarket for a radiator hence why I requested Advan to look into improving upon BMW's PPK design as there's a place for it in the air duct. The stock radiator is partly responsible for cooling the AT trans.

Sorry, as its the same price as the secondary radiator I am amazed that its the same price!! Very interesting.

From my understanding (and open to correction) 15% of the radiators surface area is dedicated to the AT heat exchanger which I think is at the bottom. Rather than be cooled by fresh, cool air like the oil cooler, the AT relies on the overall temperature of the radiator to keep it cool. If you radiator is struggling to keep water temps down than its not going to work well with the atf and likely to make matters worse. And unlike the water cooling, the ATF doesnt have oil cooling to assist it.

My belief is that if you can cool the AT fluid before it gets to the radiator then it will transfer less heat to it and therefore even assist in keeping water temps down - maybe peter or justin could clarify that.

In regards to the system, I am still interested and willing of we can make it work on a 1M or even something different. I don't know the water temps but oil temps are certainly high - suppose the two are related.

I am in the GB for the P3 Guage so will be able to have more info on hand.

Thank you.

Hi mate,

with regards the Stage 2 oil kit working with the front bar of a 1M, I really need to have a good look at one in the workshop.

There is no reason for the hardware not to mount up, but the efficiency of the kit will be significantly reduced if airflow to the core, is not optimal.

As I said previously the heat transfer capability of the cooler, is largely dependant upon the amount of frontal surface area, that sees clean air at speed.

As per the nice pic provided by Steve, the Setrab 20 row EW core of our Stage 2 kit is positioned optimally behind the RHS air duct.

Do you have any fellow BMW mates in Sydney, that just happen to own a 1M that you could persuade to let us have a close squiz at?

Or for that matter are there any 1M owners reading this thread, that would allow us to investigate the likelihood of our kit fitting the 1M?

Cheers,

JD.

Hey Ian I suspected that was the case.

IMHO,

what should be open to debate is why did BMW in all their wisdom, install a secondary radiator of such meagre proportions into a M vehicle, that is targeted at the track day enthusiast?

It makes you wonder if this was there way of moving all those BMW PPK components that were never sold, as the cost versus performance ratio of the kits were somewhat underwhelming.

Anyway whilst I am not saying it can definitely be done, as we have not performed a close inspection of the 1M front bar, but it would have been nice if BMW had fitted up oil and water coolers more in line with the volume of our cores, for the dedicated "track day" car that is the 1M...

I only saw water temps of 124 max at last Friday's track day, which was quite reasonable. It was a cool day though. On hot days I've seen (when I bothered to look) 138 degrees oil temp on track. Ambient temperature obviously make a big difference.

You're suggesting that the new/bigger 850w fan requires being hooked up to the DME? I haven't fitted my kit yet but presumed the bigger fan, in conjunction with the supplied relay, will just run off the output used by the standard 650w fan. I hope so as I'm not looking at getting any recoding done after install. Recoding is required if you're using the PPK higher power retune though. Tell me if you think I'm wrong.

I'm not sure that the bigger (or any) fan is required on track. I think your high average speed combined with the extra LH radiator will make the difference. The bigger fan is only needed for low speed running/city traffic on hot summer's days etc. Thoughts?

Justin - I know it's a completely different car but when I was at the dealer a little while ago I had a good look at the new M5 and inside the front bumper and it appears to have a similar setup to the 1M. I thought it came standard with a dual oil cooler but it would not surprise me if I had mistaken it for an additional radiator. I lost count of how many cores they had in there I'm sure it's setup up this way for a purpose.

I thought the same thing but after reading the instructions it wasnt the case.

From my experience, if a bmw component needs to be installed onto a new module socket, then only coding will make it work.

[TimMc]

Perhaps you're right. I hope not. If the DME just "thought" it was feeding a signal to the original fan then there should be no issue. I'll try and read up some more & see how the hardware/connections on page 21 (A5* Socket contact, on DME control unit A6020, plug X60101) differ.

[BMW86]

I'll take it off your hands Tim
