Some have said that engaging sport plus triggers heating of the coolant thermostat to open it sooner and possibly also earlier engagement of the fan. I don’t think there is anything similar for the oil thermostat.

[Jambo1]

I think this is it! I get into sport mode and the thermostat appears to be open from the get go. I’ll leave in comfort and observe.

I just installed the Mishimoto oil cooler this evening. Literally a 15 minute install. I’ll post back with any results I see from it.

Trying to decide which route to go on upgrading the coolant heat exchangers and radiator.

Not gonna see any difference as reported by everyone whose installed them. They certainly look much better than oem though.

So these are waste of money as they don’t do anything more than stock?

Strictly speaking of the intercoolers here but there has been little to no real World examples of improvement. And that was only shown on the track. Not worth it for the street outside of the aesthetics.

I thought that testing had shown minimal to no gains from intercoolers at near stock power levels unless the intercooler cooling system was also upgraded. I read the current question as asking about upgrading the heat exchangers for the intercoolers.

My take is that upgrading intercoolers and their heat exchangers is much more important for a track car that sees repeated peak boost in a short period of time rather than a highway pull car that sees an occasional pull.

I installed CSF intercoolers. Don’t notice any difference. I wanted the meth bungs on the cold side. Will probably add the heat exchanger upgrade at some point. May also build a motor.

You have a problem. I would take the car to the dealership for a diagnosis. Probably something wrong with the gauges. I am sure the oil and water are getting up to temperature.

It’s only when it’s super hot outside. The oil temp will go up slightly on a longer run, but won’t get to the middle of the gauge as normal.
Otherwise, it’s all normal when it’s not super hot outside. Can you confirm with your car when you’re up and about - as you’re in the metroplex, cooking outside, just like me.

By the way, a much larger gathering of Cars & Coffee in Southlake on the 26th if you can make it.

I took the M5 out in the North Texas heat for a drive down to Northpark. I can confirm the oil temperature did not get near 210.

I would like to come to the cars meet in Southlake but I have a previous commitment. Maybe we can meet up at the next one and it will be cooler. There are a lot of DFW F90 owners on the forum. It would be super cool to have a big M5 meet up to make the Cali members jealous.

You can’t even see the oil cooler. There is no cosmetic benefit to installing one of these. Why would you believe I will not see any improvement in oil cooling?

I won’t have my tires in time to make our next track session so I’ll be a month out before I am back out on the track.

Can you please direct me to where people have installed the upgraded oil cooler and reported no benefit?

My question was based on track use. These cars have more than adequate cooling for even spirited street driving.

The original question was in reference to upgraded heat exchangers for the intercooler, coolant, and oil cooler. My issues only become apparent during track use.

[pbonsalb]

The track offers the driving conditions where improvements should be seen if there are any. ShawnHayes has extensively tracked 2 of these M5 and has not found any need to change engine oil/coolant or intercooler cooling. I do knot recall whether he has datalogs. There probably is room for improvement under extreme conditions like the track.

Shawn has provided feedback and has not had similar experiences as I have encountered. Anytime you can increase your cooling surface there should be some improvement. While minor improvements alone might account for much the small improvement from all upgrades could net just enough to keep things manageable.

I am also not sure that others are tracking their cars on E30-E50 stage 2+ tunes.

While the cost vs. benefit of some of these upgrades are not justifiable to some, seeing 250*F + oil and coolant temps doesn’t make one feel all warm and fuzzy.


In a side not, as soon as the engine is built I will be adding an FI Interchiller as well. You can’t beat consistent 32* IATs.

What about having heat using the FI interchilleR?

Where would the heat concern be?

[pbonsalb]

If you are tracking with more power than Shawn since you are on an E30-50 Stage 2 tune, it makes sense you would be more likely to have heat problems. I’d buy all the cooling parts — you aren’t stopping in you modding since you plan a built motor and if you blow this one up, you have to buy an expensive core for the future built motor.

I said intercooler…Not oil cooler. Never heard of anyone having oil temp issues. Even at the track. Are you seeing issues there or just looking for something to spend money on? Which I get. If you got it spend it.

The question was never about buying an intercooler. Clearly, as I mentioned a couple of times I have been dealing with elevated oil and coolant temps, so now you can say you’ve heard of oil temp issues.

I am not sure what your kick is, but I am asking these questions in order to find the best method to reduce the temps I am seeing under my use conditions.

That N63 Intake oil cooler thermostat valve would allow more flow. I have not read much about it. I probably won’t put one on my street car. I did install the 90C coolant thermostat.

That oil cooler valve, the ones from n63 and Gintanni don't fit the g series newer model n63tu3. Not sure what the op car is though. Same thing for the tstat, the avail 90c doesn't fit the n63tu3.

I just got my custom 95c tstat from bavlogic. Installing Tuesday morning. He advised not to do 90c as it would likely throw a code and cel.
