I have followed this thread with a great deal of interest as I had every intention of selling my beloved Porsche 968 and Daily Driving and Fun Driving my 335i. This proposition only works for me if I can rely on my 3er to deliver the goods for more than 16 minutes at a time. In 75 degree heat I can get enough track time to run until I am out of gas, but in 90 degree heat, I can only get in 16 minutes.
So, I have seen the solutions offered here include:
- Larger oil cooler
- Remove the coolant or run a more diluted mixture
My questions though is this. Does the BMW Performance Power Kit solve the temperature issue? The kit contains all of the additional cooling hardware and software that is found on the z435is, 335is, and 1M. I would think (like to believe) that BMW would not let an M product out of the door that could not lap for days on end without any trouble at all.
Does anyone here have any data or information related to this kit (the Performance Power Kit) or these cars and there ability to handle track days in the heat?
It is an expensive proposition to install the PPK, but the value proposition for me is there if it will accomplish what the Stett cooler does, while maintaining my CPO warranty and coming with a 2 year warranty all its own.
Thanks for the feedback (and the flames - if I read anything about the PPK over at the N54 turbo engine forums it is always about how the PPK doesn't make the horsepower - and my focus is on removing more heat).

Well first of all, your focus is completely correct. Remove the heat. That'll allow you to practice your driving more and you will become faster. This isn't a more horsepower flame, I just know from experience that reliability and handling are the main issues with our cars.
The 335is, which is what you would have essentially, overheats at the track. BMW did some other things with the 1M to keep it cool: more air to the extra radiator and oil cooler with better ducting design and there is a large air outlet behind each front wheel which allows the hot air to get out. I can't say if you can run the 1M for days as I have no experience with them or seeing one being driven hard.
Use one of the proven methods exampled in the spreadsheet: Stett Dual, ER Dual, both with distilled water and MOCOOL. You could also do the PPK with a STETT or ER single for the added radiator. Probably good for an MT.
God luck.
