oil cooler results #2

[mro]

Thats what my thermometer said

Ya got a very cool thermometer there.
I have to read the numbers off the little LCD on mine.

Isolating the in/out temp might be achieved by using a short piece of tubing which you can aim the sensor thru. May need more than one tube as it will start to acquire heat from the surrounding area.

To do it "right" would be to get a professional type monitoring system like I used to solve a coolant/engine over heating problem, but it cost over $600.00 and have never noticed one made to check oil temps.

You mentioned you have access to a lap top.
When I was into "hot rod computers" there were temp monitoring systems which could measure 4 or 5 different spots at the same time and show temp on screen in real time. I don’t remember what they cost but was not too much.

Frys electronics should have them. Can at the least measure temps of 100c (212F) and don't see why the would not measure even higher temps.

Infrared heat sensor..

I have one of those heat sensors and it is accurite at long distances and will only show readings of the area of the red dot. I use it in my job and I can spot over heated electrical components on a circute board at 6 feet when the object is less than a 1/4" square.

I did a test of my oil cooler which was a $40 cooler from JC Whitney, by doing two runs on the freeway under the same conditions, temp, speed, distance. One run with the oil cooler and one without. Both runs were done with an oil pressure guage mounted on the engine where I could easily take readings. The test was run on the 71 freeway at 98 degrees and 80 MPH for two miles. Without the oil cooler the oil pressure was 20 lbs. with the oil cooler the oil pressure was 42 lbs. The oil temp going into the cooler was hot enough to quickly burn my fingers through the glove, however on the "out" side, I could hold the fitting with the glove on. Not extremely scientific, but it convinced me.

That convinces me. Just sold one of my XS coolers,
but have one left.
Sounds like it's time to install it.

My thermometer consists of a lense and an extra laser which is only used in sighting the object. It has a 1 to 6 ratio, meaning 6ft away 1ft(diameter) circle measured.

[HobbyMan]

Results today yielded a 20deg drop. Ambient air was about 58 deg. Temp in was around 200 and out was 180. I had been driving around on the freeway at about 80-90mph for about 20 min.. I pulled off on an exit and pulled into the first parking lot I could find and took the measurements with the engine running. I am trying to not let the lense "see" anything else but the fittings on the cooler.

[MAXIMAN]

WOW...the 20 psi without to 40 psi with is a huge indicator of relative viscosity (directly proportional to heat).

Though I've never actually measured it I have felt it. Rode down the highway at 75 mph for 5 or 6 miles ...pulled over and felt the in versus out on my cooler. The input was so hot it would blister almost immediately. The outlet of the cooler was cool enough I could hold it for several seconds before it got uncomfortable. that alone convinced me.

But common sense tells me that a cooler certainly could not hurt anything...it can only help. Of course I am running a "customized" rig. I have a B&M plate style cooler. The exchange rate of this type cooler is supposedly superior to a fin/tube type.

Here's mine:




Moderator note - I trust you meant to say "not" hurt anything - put it in that way for you. KT

MAXIMAN, where did you get that cooler? I really like that setup.

[MAXIMAN]

It's a B&M SuperCooler in polished aluminum. It's a plate style obviously instead of the old fin and tube style.

You can get them from most any autoparts store. I got mine at NAPA. I think it was about 75 or 100 bux.

The thermostat is B&M too. Opens at 180 degree. The SS tubing that connects the thermostat to the cooler I made myself.

I do like that idea about the thermostat for cold weather riding and initial startups. I worry about water in the oil as a combustion product.

When it's really cold...like 40 or below...running a cooler like this B&M with no thermostat won't allow the oil to reach proper temperature.

Cold oil is probably just as hard on the engine as HOT oil.

Does the xs/xj system or the thermostat have some kind of bypass in case the thermostat ever fails to open? Would that failure cause the oil circulation to stop?

[HobbyMan]

NO. the thermostat controls oil to the cooler. If it fails to open, the oil just flows back toward the engine.

Adapter

Is there anyone out there making adapter plates? TC?

[xschop]

adapter

I was considering making some (copying the lockhart style one now) I just sold the 80G bike that had the factory cooler and I didnt inspect/look it over for design....Problem with that is a good (a.k.a. cheap) source for the material.....anyone have good pics of an uninstalled one?

[81xsproject]

TC will probably beat me for this, but it seems like there sould be a way to combine the adapter plate and an automotive filter adapter so us folks with coolers could also run regular oil filters. But, since I don't really understand either, I don't know. All I know is that TC said that having an adapter AND one of his SOFA's would make the filter too low to the ground.
