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? |

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.

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.

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! |

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. |

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. |

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. |

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. |

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. |

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'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? |

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.
