Two questions regarding the XB cooling system... (and I'm assuming the 9 and 12 have the same system) At what engine temp is the cooling fan programmed to engage at? Is it measuring oil temperature or ambient temp around the engine? Also, is the oil cooler passive or is it thermostatically controlled? thanks! WYD (25 days and counting) | ||
| BadS1 |
Thermostatically!!! | ||
| Vegasbueller |
WYD: Per the MM with the key on, the fan comes on at 428F and goes off at 356F With the key OFF, the fan is on at 338F and off at 302F Nick | ||
| Vegasbueller |
And it is controlled by cylinder head temp. | ||
| BadS1 |
Yeah the fan is not the oiler cooler though.Thermostsat is right above the oil filter. | ||
| Whosyodaddy |
Thanks for the info. | ||
| Blake |
Fan is thermostatically controlled as stated above. The oil cooler does not utilize a thermostat. It is always in the circuit. | ||
| BadS1 |
You better go look at the XB Blake.Your lost. | ||
| Bud |
i'm with blake there's no oil cooler thermostat on a xb gr,b | ||
| Vegasbueller |
I agree with BLake and Bud... just looked all through the MM. No mention at all of a thermostat controlling flow to the cooler. N | ||
| Brucelee |
As an add on question, does anyone make a larger oil cooler and/or an additional one for the XB. Those of us who ride in hot climates might want more capacity! | ||
| BadS1 |
It works in much the same way as a Jagg's and A Spurgin Bad Boy Oiler cooler and they both have thermostats.I've owned both of those.Ones a return line and it won't start cooling until oil temp is up.The Thermostsat is just beyond the oil filter where the lines are.Do you guys see any electrical going to the oil cooler.....Nope. Bruce the only other cooler you could add would be a spin on in front of the filter but I haven't had any experience with them and don't know how the system would react with it added to it. | ||

badS1, i have taken a part my xb engine 2 time's believe me in the oilfilter mounting plate is no thermostat. the only 2 things that are located in/on the oilfilter housing are a oilpressure switch and the oilpressure regulator ( bal & spring type ) i mis the point about the electrical connection ( most thermostats are pure mechanical ) regards, Bud | ||
| Vegasbueller |
Do you guys see any electrical going to the oil cooler.....Nope. Why would anyone think there is electrical connections there? I am trying to follow what you are saying... is this something that is inline with the cooler? I have been all over the MM and can find absolutely nothing about a thermostat. Usually, on applications like aircraft and hi po motors, the thermostat has provisions to bypass the cooler until a certain temp. Looking at the lines, there is no provision to bypass the cooler during cold operations. N | ||
| BadS1 |
So what your saying is that thing cools all the time????I can't believe that. | ||
| Vegasbueller |
By looking at how the thing is plumbed in and reading the description of operation in the MM it sounds like it circulates oil through it all the time. Kind of like an add on tranny cooler, it just sits in series with the oil flow. Here it is straight from the book: "Oil is pressure fed from the oil pump to the oil cooler via an external steel line. From the oil cooler, oil flows to the oil filter mount. Oil travels through the filter mount and into the filter then through he outer filter holes." N | ||

In cold weather I cram a shop rag into the scoop. I don't need additional cooling in 35 degree temps. | ||
| Vegasbueller |
Wow.. 35 degrees. We don't see too many of those days out here! | ||
| Bud |
In cold weather I cram a shop rag into the scoop. yep, me to on my 16 miles to work other wise the oil is still cold when i get there, with the rag it's just getting on working temp. | ||
| Blake |
Dana, It is true. Surprised me too. My buddy Keith covers his oil cooler air inlet in cooler weather. | ||

Consider the issues with a thermostat on an inline cooler that receives all re-circulating engine oil. A thermostat is possible on a passive cooler or one with a pressure relief type of bypass but that's not apparently how this system is designed. And I have seen a much longer cooler that replaces the stock one, but it eliminates the scoop so I don't know how valuable it really is. My stock one works well here in Phoenix on a summer day at 115+ degrees. | ||

I wish 35 was as low as it gets around here.  If I can continue commuting to work until Thanksgiving I'll be pretty happy. | ||

One of the reasons I originally brought this up is because on my 600RR, I would consistently see water temp go up to between 220 - 235 degrees during stop/go traffic - even with outside temperatures in the mid '80s. (The RR's radiator fan kicks in at 220.) I also seem to remember when I had my '04 12R, that my inside right thigh was getting baked from the fan exhaust. Guess that's Erik's way of ensuring XB riders won't wear shorts. :-) WYD | ||

Darrell, the fan on my R1 kicks on at 219 deg, but in normal traffic I usually see temps in the 185-205 range. Stop for a couple of lights & it will get as high as 226...thats the highest I have seen so far. As soon as I start moving even just a few feet the temp will drop 15-20 degrees real quick, most likely just due to spinning the waterpump a bit quicker. | ||

WYD, I'm working on a heat barrier for under the seat. Should have it done this week. I'm putting some finishing touches on my heat barrier for under the airbox right now. Taking some temp readings etc...... | ||
| R1DynaSquid |
odie...what you planning on using for a heat barrier? I actually lined the bottom of my seat pan with aluminum foil to hopefully direct some of the heat away....it seems to have worked too. | ||
| Odie |
I have made my heat blanket from products from DEI (Summit Catalog) and my heavy duty sewing machine. Been running it for 2 days now and tomorrow, if I have time, I'm going to take some temp readings. I'm making the seat heat barrier out of the same materials. Protects from radiant heat up to 2000F. Used a laser temp guage on my header right as it exited the head and it was around 280F. Should work just fine under the airbox and the seat. | ||

My Corky Bell Turbo book talks about airflow through intercoolers but I am guessing that the idea is the same. He states that on an unducted rad, only 1/4 of the air hitting the rad passes through and cools. The mouth of any duct need only be 1/4 the size of the rad area and diverge out to the rad. Convergent ducts spill air from the sides of the opening, past the mouth rather than into it, as instinct would suggest. (Think of the air 'scoop' to Formula car motors) Much more important is the sealing of the duct to the rad surface to prevent air leakage. I suppose what I'm saying is that, if you fit a bigger cooler, make a bigger duct, too. | ||

Hey ODie, i`m on summits page can you give me the part number or url page number with item number for that heat blanket(heat screen) =$54.50http://store.summitracing.com/default.asp?target=esearch.asp&N=110&Ntk=KeywordSe arch&Ntt=heat+blanket&x=12&y=8 Wd. this be right ? Thanks Bud. | ||
| Brucelee |
Odie, are you going to be selling the heat shield products once you perfect them? | ||
| Odie |
Hogs, page 259, DEI # DEI-010401, Heat Screen, $54.50 Brucelee, most definitely. I am making some for friends locally now. I will keep you posted. Wanted to do some temp runs today but these hurricanes are putting a serious cramp in my riding and mod's. I did feel my outer airbox cover last night when I got home and it seemed a considerable amount cooler than normal so that would tell me the air going into the fuel system is also cooler. I'll let ya know....Take care...Odie | ||

rather than stuffing a rag in, why not just remove the scoop, thus leaving the oil coolers fins perpendicular to air flow? | ||
| Wyckedflesh |
Just an FYI I am looking at taking a Naca duct large enough to mount around the output of the fan to direct the air from blowing up under the seat, aim it more downward towards the tire. Obviously modifying it to work around the shock but the aim is to cut down on the thigh baking. | ||
| Odie |
Aim it at the tire to keep it hot and sticky all the time!! |
