Who's got oil coolers?
 

Need to get an oil cooler on my car. I though either Pilo or M7 was doing one. I know the Minimania and Moss ones, but would like to see other options.
Thanks

I bought a Mini-madness one.. Haven't put it on yet, hopefully next w/e....

Do they come with termostats? I had heard some come without them.

I have the Mini-Madness oil cooler and it has performed admirably.

Just finished a trip in which I was at 6 tracks, most in the South. Ambient temps rarely below 90, 95 some days. At end of 20-25 minute sessions I was generally seeing 250-265 and I tend to run well up on the rev scale (I have a 7,500 red line). I think my highest temp was 280.
I'm very pleased with the product.

a description and parts for a do-it himself..... Search away! If you use the oil cooler for the CVT (it mounts above the AC ratiator in front of the radiator, and uses the factory mounting bosses) it all looks very, very clean.

...... thanks all, don't know how I miss the Madness one as it was one of the first places I looked. Looks perfect. :thumbsup:

Onasled,

Good morning. This hot weather and track days does make one think of oil cooelers, doesn't it? I have installed an oil cooler system using the Maddness adapter plate, a modified MINI CVT transmission oil cooler radiator, and custom industrial hoses. No fuss, no muss. No instrumentation so I don't have any performance measurements. Here is a photo.

That's very trick John:thumbsup: Did you fabricate the brackets?

Sid

BTW, almost done with the WI:smile:

Sid,

A cool thing about the CVT oil cooler approach is that all of the bracketing is stock. All I needed to purchase was a single small machine bolt to install in the stock clamp. The stock CVT oil outlets didn't work for me, so I relocated the outlets and installed AN-8 connectors. The particular hoses and clamp on fittings that I chose are bulky and clearances are tight.

Keep me posted on the WI.

Over-Cooling?
 

Is over-cooling possible? If so, are there any detrimental effects?

yes
 

if you live where it can get cold enough to really gell or freeze the oil, and there's no thermastat, you can loose flow.
Also, with no thermostat, engine warm-up times may increase.

JLMs thread...
 

John, was that a lot of custom work to relocate/install AN connectors...ie, welding required?

Onasled, Sid, and all,

I'll share my observations and opinions.

The rework of the CVT oil radiator does require welding and not soldering. I'm absolutely paranoid about a solder joint failing under temperature, pressure and vibration stress.

I think the stock oil filter assembly incorporates some sort of a thermostat ! I'll tell you why: Since installing the oil cooler assembly, I have heat cycled the oil a couple of times to look for potential leaks and other problems. What I observed, by feeling the hoses and radiator core, was that the inlet hose would stay at ambient temperature for the longest time. Then, fairly abruptly, the inlet hose would get hot, not warm, but hot. The "hot" would spread laterally thru the oil radiator from inlet to outlet and, then, the outlet hose would get hot.

A comment on the dynamics of the radiator. The "hot" oil felt like a "front" moving from left to right across the radiator. It seemed that with the plate and fin construction of the oil radiator, the hot oil moved with equal speed in each plate across the radiator. I was impressed with the uniformity of the heat distribution. There was a distinct clear line of hot vs cold that was easily demarkated just by touch. Pretty good distribution of oil flow I thought.

Not sure whether my observations about the sudden heat rise can be interpreted differently. Any other ideas? I'm comfortable not having a stand alone oil thermostat in my system.

Oil Pressure
 

For people running the oil-coolers, how much did your oil pressure change?? When you were still OEM oil cooler, and to your new upgraded oil cooler...

Any data would be good, as far as "before oil cooler" idle, "before oil cooler" cruise, "before oil cooler" WOT, and "after adding oil cooler" idle, "after adding oil cooler" cruise, and "after oil cooler" WOT..

Thanks and much appreciated

I'm wondering what oil temp are you seeing during cruising speed (freeway/street)... I just finished my oil cooler install... I haven't driven my car on far distances or hard yet.. but cruising tonight, I was seeing my oil temp at a constant 210 degrees..

From doing a search on this forum, it seems people are seeing about 235-245 on their oil temp.. So 210 is definitely good....

Wondering what is yours w/o driving hard..??

Thanks

oil cooler
 

I thought that the MCS had an oil cooler? Are you upgrading?

Good work
 

Gilbert,

Which oil cooler system did you end up installing? How did the installation go? Any hints or suggestions to the rest of us??? Leaks? Please keep us posted as to your impressions.

Have a good holiday.

I have upgraded to the MINI-MADNESS oil cooler... Since I also am installing their A/W intercooler, I opted for their optional top mounted radiator...which installs on top of the radiator....

What I like about their oil cooler setup, is there is a place to put an oil temp and oil pressure sender for my gagues :thumbsup:, so it makes it too easy...

Their install recommended time is about 2-3 hours.. But getting the Autometer Oil Pressure was a mistake because the sender is too big to fit in their "oil adapter plate", so I had to wait another 1.5 weeks for my DEFI oil pressure gauge/sender... So my install took a good 2 w/e.. But I'm sure if I didn't have issues w/ the gauges, I could have probably finished in 4 hours.. I always to just take my time , with breaks and stuff...

My main concern was the need for an external oil pump to keep the pressure good, since of the added distance travel for the oil.. but as I was testing it last night, my pressure seems to be of average... (+-)20 psi on idle and about 40-50 on cruise (5/6th gear)... I will need to gather more data and compare it to a post I saw a while back regarding oil pressure data..

Leaks?? So far none that I can see, but I have only driven it for a good 20 minutes.. https://www.northamericanmotoring.co...es/NAMgrin.gif

Now to figure out if 210 F degrees on my cruise speed is lower than the a stock OIL cooler..

///Thanks

Gilbert,

Sorry it took a bit. Actually, my temps top off at 210 when cruising. I'm usually more around 180-190. Will be cruising tomorrow on the way to the track, so will get more info on both conditions. Will let you know.

NNN

Norm and Gilbert,

I hope to be at the track with Norm tomorrow. Gilbert, I'll keep an eye on Norm's guages and see what they read, pressure and temp. I'm very interested as well. Norm has the same MADNESS intercooler and oil cooler set up as you do. The weather is expected to be 74 degrees tomorrow. Not particularily hot but should give the oil cooler a workout.

Until tomorrow...........

Can you tell us what type of guages and sending units you are using with your oil cooler setup. I see where someone is having trouble with the Autometer sender not fitting. Hope you had a good time at the track. :thumbsup:

Thanks John, that would be helfpul.. I just finished my drive, I wasn't really pushing the car hard since everyone is heading back home from their vacation.. But here's a little bit of data I got.. Temperature outside is about 89 degrees... My oil temp was from 180-210... On the street, cruising about 35-40, I did see 180-190.. On the freeway, I seemed to be constant at 210.. When I was able to push the hard beyond 5K RPM, I saw it reach about 230 but as I cruised, went back down to 210...

Have fun in the track. Till tomorrow then..

Newbs, my friend. I have the Madness setup, which as you probably know, includes the very trick adaptor plate that they designed. It has two sender pick-up points built into it. According to George, there have been many issues regarding gauges, due to where most people normally connect them. One reason he designed the plate.

http://www.mini-madness.com/index.as...ROD&ProdID=219

The guages I have are the Defi two-gauge pod that sits right/left of the tach.

betet - I'm seeing 210 during cruising speeds on my MCS with -15% and stock oil-cooler. Its good to know about your experience with the autometer oil sender and the madness adapter plate. I use the autometer and do plan to buy the madness cooler. It looks like I will have to maintain the current sender install point.
