I'm FBO running an E30 I'm guessing around 400hp, with a Mishimoto intercooler on a '07 E92 N54. If I do about 3 WOT runs after the car is warmed up my oil temps get to about 250 and I get that hot engine/hood smell pretty quickly.

My question is what upgraded cooling mechanism should I look into? Not looking to add any more power, and I've read a ton of posts about meth and upgrading the stock oil cooler, but none really about doing one versus the other. I'd really like to avoid meth as I hear of the degree of difficulty to get it installed and that it really doesn't help that much in oil temps. Should I also consider maybe upping the Mishimoto intercooler to a larger core? I'm in California by the way which the temps aren't that crazy.

To start, this section of the forum is N55.

That being said, I would go with meth even if it's "hard" to install. If you think about it for everything that meth is able to do it is really worth it. The cooling power of that type of injection is absolutly insane. I don't think I would go all the way to get it port injected. Even charge pipe injection is absolutly great.

I don't know what size your intercooler is, but I habe a 7" from ETS and it was kind of annoying to inatall since I had to trim a lot of the inner bumper and didn't have a proper garage car lift. If you have a 5" or 5" stepped, you could consider upgrading to a 7" but it won't be near as good as having meth.

Upgrading air to air cooler is brilliant but the laws of thermodynamics makes it so you can't achieve cooler temperatures that will be lower than your intake temps (unless you are running a cooling fluid in that intercooler).

So, meth is way more efficient cooling wise than a intercooler but all these methods are used to cool the INTAKE AIR that will be used for combustion. If you want to efficiently cool your oil temperature, then you should use an oil cooler, but your oil temp seems pretty normal to me (~120°C)!

MHD has an option to run the electric pump more for different target temp. Thats should be more than enough. Stock i think it targets 110 C u can bring it down to 95 C i think. With that target ur oil will drop considerably.

always wondered about this. I assume they only way to drop the temps this way is to have the water pump and/or fan running more? And the trade-off is you drop the life of those parts?

Anyone have experience in doing this? I've already replaced my water pump twice and it's not a E92 part I'm a fan of... the trade off might sound worth it - overall engine coolness/reliability versus an overworked water pump? That being said is there an aftermarket water pump that's better and more reliable than the stock one? You don't hear too much if at all about a water pump upgrade.

Like others have said, run the MHD cooling option to sport before going out for a spirited drive. Then flash it back to stock for daily driving. Most people in hotter climates leave it on sport. It keeps the oil temps in the 230-240 range even after back to back hard pulls.

[Emilime75]

There is no water pump upgrade.

The MHD option sounds pretty good. Also, a thermo controlled oil cooler would be good, i.e. an additional cooler with its own thermostat that opens once temps get up there.

There's the stock oil cooler thermostat bypass, but I don't think that's a good idea as it takes the oil longer to get up to operating temp.

I don't have an Android. Can't this be done through the K+Dcan method?

Also, from what a gather - to eliminate switching cooling modes or extra stress on my WP, a aftermarket oil cooler such as the Evolution Racewerks sport might be my best bet. Thanks guys

What year is your car? Does it have the OEM oil cooler?

Well you need a Android device for the app and the K+DCAN cable for the car.

And you connect it to the phone via a OTG connector.

1.) MHD sport cooling
2.) BMS oil thermostat valve

If your car doesn't have an oil cooler then may look to install one. Either retrofit a stock unit or piece together an aftermarket solution. With the MHD sport cooling my oil temps were 210 - 220. I ran it like that every day for over a year.

Two Oil Coolers? One factory + One aftermarket. 18-26 Row will do the trick. 2-4 More qts of oil sadly

[nicky dj]

Ugh, so this whole time I thought I had an oil cooler because my build is an 03/2007, I have the fender vent, and my oil temps never reached past 250 on daily driving only slightly over 250-260 when WOT 3-4 consecutive times. However in further inspection, I noticed my oil filter housing is NOT built with the oil cooler .

So I guess my question now is is getting an oil cooler retrofit WORTH it. I keep reading that unless you track your car it's not, however FBO running methanol it concerns me a bit. Looking at getting the ER sport cooler with retrofit. Any cost ideas would be most hopeful as well. Thanks guys!

[Emilime75]

I'd look at aftermarket. It's an opportunity for better efficiency. Maybe a combination of stock oil cooler thermostat/housing and more efficient/aftermarket cooler?

[Turbod]

I have a stock cooler. In the winter I hit about 230F. In the summer even after hard driving I don't go above 250F. I would still prefer to sit around 220F which is why I use the MHD option.

I knew it! Why I asked your year...

I would get an oem one of a parted car. Should be cheap and easy to add in. Just my 2 cents. Car goes into limp mode if the oil gets too hot...

Get a Oil cooler retrofit , then add a secondary cooler. i can show you my setup. I stay at 210-215 (operating temperature 190*)
