128i Track Tempts
What oil and track temps are you guys who regularly track your 128i seeing? I’m an relatively experienced driver on the track (50-60 days) and am taking a bones stock 128i to the track in a few weeks.
Ambient tempts will be in the low 70s

My oil temps were high. 275 and would have gone higher if I hadn't backed off. I need to add an oil cooler. Coolant was fine. Didn't move too much from regular driving.

I installed a little N20/N52 water-oil cooler and had no problems since. |

In mild weather like that, I'd see an oil temp of 260F if I was really pushing it. 240-250 if I was just driving conservatively (as far as driving on the track goes). I've never bothered with coolant temps. Never had limp mode or half limp mode before, so it doesn't worry me (something about ignorance is bliss). The electric water pump drops the temperature pretty drastically once the DME goes into its "Sport" mapping. I've never seen oil temp crest 270, even when it was 100 degrees out and I was driving aggressively.

Hi Bobby! Glad to see you got a 128! Great cars. (I'm on bimmerforums, we'd talked about some Z3 stuff)
I have seen some of your videos. You will have to add an oil cooler. There is no getting around it. You will without a doubt get the oil hot enough that you will go into limp mode. Cooler days will get you an extra lap or two than hot days, but it will happen. Every session. The set up I used to solve mine was a 135/335 oil filter housing and then a small/medium cooler from Ebay. https://www.1addicts.com/forums/show....php?t=1519384 |

That is where I was going with mine, but with running the Z3 in WRL, I had zero time left for TT. Made me sad, but I ended up selling the 1 to a guy on the forums here, and he has been tracking it regularly. It will very likely be a great platform for TT5/TT4. I never quite got there, but was very close. Needed another year of development I think, and it would have been aces.

I was at the track yesterday, ambient temps between 35F and 50F over the course of the day and I was seeing oil temps get up to 270F and a few times up to 280F. I will be installing an oil cooler before the next event.
Just to confirm, the N51/52 gets oil temp reading from the oil level sensor in the pan?

I do not see the same part on the N51/N52/N54 engine diagrams, but, that is what you would want to look for. Otherwise, the only other place it could be is in the pan. The sensor on the oil filer housing is a pressure sensor not a thermometer for taking temperatures. When I tracked an auto N51 I was seeing 280f+ oil and 240f+ water temps. Not good at all. A 26 row cooler helped, but, not enough with the auto. The car really needed a larger radiator too and a dedicated trans cooler so that radiator capacity isn't wasted on trans cooling. I ended up in a 135i before really tearing into the 128i. Fun well balanced car but I wanted more. Last edited by bbnks2; 12-19-2019 at 08:10 AM.. |
