Congrats on not overheating, I don't know what to tell you other than my experience with the N54 motor on five tracks, all located in hot humid environments. It wasn't limited to just my car. My buddy had a AT and would hit temps that caused the tranny to lock up (mine was a 6MT). If you have never noticed a loss of power or limped with your N54, you may need to drive harder ![]() FYI: I was running r comps with race pads and SRF fluid.

As a owner of 400rwhp n54 car I agree with you 100%
Unless you are running water/meth you will hear soak so quickly and lose MASSIVE hp on the track. Anyone who disagrees is retarted.

I think it's a good car, but its not the car for me for the environment and tracks I enjoy. A small cool track with tight curves, I have little doubt the 1M do fantastic.

So the point is the M3 might be a better track car, some other "experts" have said so and if that is where it will spend it's time, then get an M3. I want a small nimble back-road warrior with no fluff that is fun below triple digit speeds. |

Turbocharged engines have very conservative engine management systems to keep them running safe under all operating conditions. The car will feel slower in hot weather just due to the ECU listening for knock and pulling timing advance accordingly. That's done on purpose to keep the engine from grenading, but it will make the car feel much slower and less sharp than in temps 30-40* cooler. On a hot track day dumping a 5 gallon drum of 100 oct unleaded would go a long way towards getting the power back. That tends to make the ECU more comfortable to dish out the timing advance again. |

So since I didn't get the same results you are claiming about your N54 and the 1M on the track you just discount my time on the Miller Mororsports track as not Actual Track Time?
So far you are the only person to report these issues on the track, including several Magazine reports, I suspect your issue is more about defending your M3 than giving an honest review of the 1M. Ultimately this is the highest level of flattery for the 1M when the M3 people feel so threatened they stoop to trying to debunk the 1M to avoid any true results that say the 1M is equal to or greater than the M3 at everything, which is what all the Magazines testers are reporting.

Myself and dare I say several others who have experience this well known "heat soak" issue absent meth/water applications will get that all too familiar timing pull. BMW isn't to blame, I would do the same for cars under warranty. My N54 came with the pre 25.5 progman software where it appeared BMW didn't put in such aggressive timing pull. The car would run at the limit constantly until I popped the turbos on a hot day at the track. I like the car, I don't intend to hurt your feelings or make you doubt your purchase so why don't you wait and see for yourself. I tend the find anyone who is too overzealous holds little credibility. As far as feeling threatened, I hope the 1M kicks the pants off other cars, but I think everyone should temper their expectations. As far as attacking track experience, do you remember your statement to me? Let me help you.... Quote:

I LOVE the 1M, fully support all of its functions. But somehow I agree with the OP.
Just throw on an oil cooler and it is set!!

I agree that the OP could be correct with the heatsoak issue. Anyone dismissing this as impossible is either:
A) not accustomed to hard driving in the heat -or- B) putting way too much faith in the cooling properties required for how hot our motors get. Remember when BMW overlooked the oilcoolers on the first 335i's? I'm not saying this car is doing it, nor am I saying it's not, but we haven't exactly been in the hottests months yet either. A final note to the M3 vs 1M topic, If saying that the drop-off of TQ or HP after multiple hotlaps is "underwhelming" then would that not be a miniscule point compared to never being able to push an M3 into it's highest level without being on a closed track? I have had 2 friends that loved thier E92's in Germany, but sold them as soon as they got here because they just couldn't find anywhere to "open them up". To me the 1M is a no-brainer. But, to each their own.

The N54 will heatsoak on a hot, humid day. I have run my tuned 135i N54 on tracks in the south (Georgia, SC) and on my final couple laps each session I can feel a slight loss of power. Generally it isn't enough of a loss to be to concerned with during relatively short HPDE sessions. If I was a club racer (I suspect the OP does multiple trackdays or is closer to being a club racer) then I would be concerned about that loss over long track sessions. People you don't have to defend the 1M, it is probably a great car, but it is not the giant killer the fan-boys think it may be.
