I'm keeping an eye on this... Can you be more specific on price... Been thinking of the M24 upgrades...

I don't know if you've done this yet or not, but I have my stock cooler stored in my garage in plastic. If you want to use it for measurements (I'm pretty close to you) I'm happy to send or maybe we'll cross paths at a track event (VIR 2 weeks from now?). |

very nice cooler but pricey. that is more than double what I paid for the GT4 power steering cooler, and that is a true BMW part. i sure like it though.

On the cooling topic, does anyone know if the M24 radiator any superior over the PWR unit turner ms (cheaper) say they run? We are already hitting 109F here in vegas. I do agree that staying 210-300 range for "prolong" period of time(versus dropping quicker) is likely unhealthy for the S65 on the long run. Few track days a year probably won't be an issue, but for some of us track addicts who also desire longevity, it's probably "reasonable" as we've seen quite a few heating issues on track events that have ended up with more than $1800 damage (as much as I would hate to pay that kind of money).

I thought I would post an update on the M24 oil cooler. I just got back from a 2 day event at Road America and I have now a two track comparison under similar conditions (temps) between pre and post oil cooler install.
First to clarify. I had posted earlier that I wasn't sure the M24 oil cooler provided a meaningful difference in max. oil temps, at least based on the stock oil temp gauge. I made a classic apples and oranges mistake of not comparing the performance under the same conditions. I ran my car at Barber after the oil cooler install and said I did not notice any diff in the max oil temp (running the mark between 210F and 300F) but that the oil temp "recovery" on cool down was much faster. I've been to Barber three times since the install and the issue is that oil temps at Barber are just hotter. The track is small, there is a fair amount of elevation change, speeds are lower and there is a lot of up and down speed changes, consequently the motor runs hotter. I had no stock oil cooler baseline at Barber, who knows maybe I would have gotten a limp mode. I've been now to Road America twice (once pre and once post) and at least a half dozen times to VIR. At both VIR and Road America I can no longer get the oil temp to the mark between 210 and 300F, which was a regular occurrence previously. At Road America (it's always cooler there as the usual summer temps are in the mid 70sF as it was this past Monday and Tues (Badger Audi Club, Road America event) the oil temp would get up to the mid-point between 210 and the next mark up (the middle one between 210 &300).. At VIR even when the temps are in the mid 90s the needle still stays below that same mark. So, overall the M24 oil cooler is effective with lower oil temps on the stock BMW temp gauge as well as quicker recovery to stock temps on the cool down lap. In addition the oil cooling fins are easier to keep clean from bugs and debris given the design is a little bit more open that the stock oil cooler. Overall, very satisfied with the performance of the oil cooler on the track (probably not a useful upgrade for street only use). Price as most of you know is expensive, but as they say, "pay for quality and only cry once." |

I'm convinced I need the cooler. I appreciate the OPs comments and review. I was just at California Speedway for an HPDE and ambient temps were in the high 90's to about 105 for most of the day. My oil temps about 10-15 mins into the sessions would climb to about just past middle mark between 210 and 300. That is the point where the idrive would display an excessive heat warning, at which point the DCT would delay shifts and revs would be limited. I tried another session running with the heater on but no luck. At 100+deg ambient temps and agressive driving the stock cooling capacity is being taxed and needs help. Funny someone else mentioned the iPhone overheating too. Mine would only last about 10mins before it shut down and needed to be cooled off.

Our cars need more cooling capacity to be run for extended periods at the track. If your engine isn't overheating, its your tranny, or its your power steering or its your brakes. Quote:
I agree that I would get more oil cooling capacity if I were regularly tracking the car.

yes but again you're talking in extremes. We're not talking about running cold oil. Picture the oil operating over a spectrum of temps. The oil cooler is only slightly lowering that ## and in situations like road racing, then absolutely is it beneficial. On the street, not so much but it def won't hurt the car. I run in 100 deg temps all year w/ no issues but have been looking at getting a mocal cooler to run up front in place of the OE |
