Dual oil coolers

Currently have the HD horizontal cooler installed and will add the Jagg 10 row vertical cooler.  What's the open on oil flow....horizontal to vertical or vertical to horizontal?  And, why (one's logic).

[IBARider]

It all depends on how you want to dice and slice your hoses.  otherwise there is no difference that I can tell.  Each cooler is going to have whatever temp drop it has regardless of where in the system.  Kinda like wiring in series... does it matter where you start......

Jagg recommended that I not do this since the drag on the oil flow would tax the pump.  They had everything to gain by talking me into it, so I took the advise as gospel.

[djl]

Don't think it matters but adapter to vertical, vertical to horizontal, horizontal to adapter works for me; both are Jagg.

[barny7655]

I do agree with Jagg, but if you have the Jagg adapter with thermostat that opens when oil is hot and you use the right viscosity oil i cant see the drop in pressure with the use of two , or a restriction in flow, may be some one else has done this ,one can check both, by removing one cooler and checking pressures, interesting topic, it would be like having one cooler but twice the size, it would look good one each side though, this is only my thoughts , with temps down here in Victoria, Australia , we have had over two weeks of  over 40 C  highest been 44C  convert that to F , and yet a not a lot of us use coolers ,i have one on mine ,so in all of that id run one if the temps are not so hot all yr round, Jagg make both products ? and there advice seems right ,may be some thing in there thinking , to do with after market oil pumps, been used as well, as cam plates, Baisly springs etc, putting increased oil pressure on the system,and having a cooler restricting it to cool the oil , good thread ,Barny

[HDDOC]

IIRC, Don from Deweys Heads ran to coolers in series. Hope he hopps in. Thinking of doing this myself.   Doc

[moose]

I run two on my 02 fatboy for the last 25,000 miles with no problems what so ever.

[HD/Wrench]

You can buy a small cooler for a transmission along with the thermostat from Summit or Jegs and make your own brackets and save a ton of money. I have done several for customers that wanted twin oil coolers.  Even did one with a small fan for one customer???  it really worked well, Bagger with a trailer pulling the mountians. More than one way to get the job done.

[ICANTD55]

FWIW Woods has been doing this with two virtical coolers.

http://www.woodcarbs.com/oil_coolers.htm

[HD/Wrench]

Thats correct I have had customer tell me about the UG/ woods kit they bought that needed 3.37 gearing twin oil coolers to run correctly. Those kits tended to have  CCP  in the 225-235 range. 

[iclick]

I do agree with Jagg, but if you have the Jagg adapter with thermostat that opens when oil is hot and you use the right viscosity oil i cant see the drop in pressure with the use of two , or a restriction in flow....

I have the HD with thermostat now, which works very well, and the Jagg rep said that these are more restrictive than Jagg at the filter-adapter/t'stat.  BTW Jagg no longer makes HD coolers.  I would still like to do it but wouldn't if it taxed the pump in any way, and I'm not sure how you would know.  Adding a small vertical Jagg to my existing cooler in series would be a simple job, maybe 15 minutes.

[apes]

I suspect that there is always the option to run a Jagg in tandem with an adapter / cooler that runs the oil through the crash bar, I suspect you wouldn't have the back pressure of 2 Jaggs and it might fit on the bike better...

[HDDOC]

Dave Brode gave me his info on the engine guard cooler and it worked out great never saw temps higher than 220*. I have a 110" now and am in the process of trying to work it into the bike.  Doc

[maintainin]

Engine guard oil cooler. Very interesting. Is there a set of instructions somewhere on how to perform this?

[Ed Y]

Ken R, who posts on here, runs 2 JAGG coolers on his 02 EG, mounted on each of the front downtubes.

[Ken R]

As Ed stated, I have been running two Jagg vertical coolers on my Ultra for about 2 years.  I only removed them this winter; not because of any problems but instead because I wanted to re-install my lower fairings.  They simply won't work on touring bikes with lower fairings. 

I ran my coolers in parallel; not in series.  In series, the restriction and resultant static pressure would be double a single cooler. 

In parallel, the restriction would be half that of a single cooler.  Of course, in parallel the oil would spend more time in the coolers.  I see that as a good thing (or at least equal to the cooling effect in series).  More time in the coolers, the more cooling effect without the penalty of excessive static pressure.

The result?  There was huge cooling effect!  Much more than with my single horizontal HD cooler that I'm now running.  The most evident effect was the quick cooling of the oil when finally freed from traffic jams or long stoplights. 

I did a several-hour study with a two-input digital thermometer under all kinds of riding conditions with an ambient temperature of 103 degrees.  Published it on the old HTT forum.  I guess it's gone now.  But it was very telling (the effect of oil coolers on our motorcycles)

I have the instructions here somewhere. PM me your email & I will find them & send them to you. I have used this now for over 40,000 miles & it works good. I did put on the Jagg offset oil filter mount with thermostat. Got it off ebay for $110. and around $15 for hoses & fittings.  No more coolers hanging around!!!     

[HDDOC]

Had a hole tread on the engine guard cooler on the old site, but can not find it now.  Doc

Jagg also told me a parallel arrangement wasn't good because the oil would flow mostly through the cooler of least resistance.  They weren't big on the dual-cooler concept in general, especially with one cooler being an HD Premium.  Even with two Jaggs they said it would be overkill. 

[Ken R]

The parallel cooler concept worked just fine.  There may have been a difference in resistance between the two, but the combined resistance is still well under half-that of a single cooler.  I took temperature drops measurements across each cooler and there was no difference (to the tenth of a degree using a Fluke dual-input digital thermometer instrument with "grain of wheat" sensors).  So if one cooler flowed less oil than the other, it wasn't significant. 

Consider if one cooler was totally restricted.  The alledged downside is that all of the oil would flow through the other cooler. That is an illogical hypothetical worst case senario; . . . .. and the outcome is the same as if you had just one cooler.   So there really is no downside.

[ederdelyi]

FWIW, just about every hipo application I've seen with regard to multiple coolers uses the parallel configuration. Several benefits, IMO. Series is more common in some industrial applications and for tranny coolers or engine oil coolers used on water cooled vehicles. They use the aux cooler in series with the built in cooler on the vehicles radiator ... keeps it from running too cold without the use of an additional thermostat or bypass valve.

I know of one that does. 

[Ken R]

Man, I'd like to see how.  I've been considering selling my vertical coolers and adapter in favor of the HD Deluxe cooler I now have installed. 

I tried just about everything to make the vertical coolers clear the lower fairings.  They can be angled to give clearance, but 10 minutes on the road and they angle themselves back against the fairings.   I even tried tying them in the angled position; only to discover that the front fender would jam against my nylon tie-wrap that I used to hold the coolers at an angle when I applied the brakes.   So, I finally gave up and took the vertical coolers off.

Ken

[dynajohn]

I have been running 2 Jagg vertical coolers (one on each side, same application woods uses) on my 03 Dyna FXDX for 2 years. They are in series with a bypass valve on each cooler. This is a 124 motor with 220 CCP and I have had zero problems with this setup. I bypass the 2nd cooler until the temp reaches over 90, then open the 2nd cooler.   

[HDDOC]

I know how to plumb in series but I am lost as to how to  plumb in parralel .  Could someone plese explain.?  Thanks Doc

[PanHeadRed]

Ken, check out the picture of the top clamp, once installed it won't move a micron. Rotating between the two positions does not require re-routing the oil lines.

[Sonny S.]

Hey I've seen that cooler before...except it was on a white RK 

[Don D]

The sykes is a nice piece for sure.

I am wondering what hose and fittings would be used to support a "parallel" installation. I know how to do it (parallel VS series) but I am wondering how to supply the coolers without taking away from a critical motor lubrication circuit. Would a simple Y in the out line from a typical oil filter adapter work or would it be better to tap the oil supply at another spot? Wouldn't it be best to return to tank with a metered orifice rather than back in the closed loop scheme we typically see?
I am working with hydraulics all the time so this is a little hard for me to understand and also have experiences with good automotive oiling systems so that further has skewed my thoughts. Maybe I am making a simple solution more complex.

[ederdelyi]

Don,
Some thoughts (some mine, some from other sources) on this:

Parallel the coolers from the filter/bypass adapter, best place to do it. A simple low restriction "Y" or "T" is fine, IMO.

While there is not a lot of "real estate" on a bike, most dry sump applications do not cool scavenged oil. I'm sure that there are some reasons I haven't thought of, but the most obvious one that comes to mind is allowing the path to the tank from the engine to act as a heat sink and help to cool the oil and thus reduce the load on the cooler(s). Some may argue that the cooler works better with a larger temp delta ... I'm not gonna go there.

Let the flood begin ... spillway gates are open :>)

[ViennaHog]

Heat transfer in a parallel arrangement is more efficient as the heat transfer from oil to air is proportional to the temp difference. In a paralle arrangment both cooler see the same high inlet temp.

[ederdelyi]

 

You went "there". I was gonna leave that one alone.

[ViennaHog]

Oh "Potty mouth", crossed the border.

[Ken R]

Dang!  Those are a lot prettier than my Jagg coolers.  I can certainly see how they wouldn't move once set into position.  They'd work for sure with lower fairings.  I wonder if they're as effective as the Jagg coolers that have multi-paths with thin walls and internal turbulators. 

Ken, check out the picture of the top clamp, once installed it won't move a micron. Rotating between the two positions does not require re-routing the oil lines.

[Ken R]

Here's a simple diagram of connecting two coolers in parallel and a picture of the coolers installed on my Ultra. 
In the picture, the engine-heated oil (red) flows to a "T" and then to the inlets of each cooler.  The outlets of each cooler are connected to another "T" where a tube carries the cooled oil back to the engine.  Please excuse my Microsoft Paint artwork.



And here it is in practice.  The coolers have to be angled forward so that the spigots on bottoms don't rub against the lower fairings. 



If it weren't for the lower fairings, I'd have kept the dual coolers on for the duration.  They really did a good job here in Dallas traffic and for extended parking lot training exercises.   It didn't take much relative wind through the coolers to make a significant difference in engine oil temperature.

The Bob Woods setup in series

[LT611]

The Woods set up look's really nice but aren't we back to the series versus parallel ? I can see where hooking up in parallel would be less restsictive but ?  ,

[LT611]

Restrictive ,sorry,can't spell this morning

[HDDOC]

I am bringing this topic back to the top to get more input. I have a 09 FLTRSE 3  110".  I have tried the HD cooler that comes stock with the bike, outside temps 80s. oil pan temps 260s. I tried the engine guard in parralle with the HD cooler and get 230*, the pluming looked bad on the bike and I still would like to see 210 to 220* in the pan. Tinking maybe adding the Jag 10 row in parralle with the hd cooler as I believe this may get the pan temp down to 210*.  Any thoughts from anyone that has tried this. Trying to keep the cost down thats why I am still useing the hd cooler and adapter.  Thanks Doc

[Paniolo]

Here is one I am running now. It is the 10 row down low oil cooler that goes up in series to a Spurgin Badboy (not sure if this company even exists anymore) heat sink oil cooler. It is okay, but temps still get in the HIGH 200s. The ONLY reason I went with this Spurgin unit is because it clears the lowers and does not rotate with vibration. I was unaware of the Eastern Performance unit.



Having said all that, I am probably going to pull the Spurgin and go back to the crashbar set up in series behind the 10 row. The bike is already plumbed for that as I ran that set up several years ago. In all of these set ups, I found that the crashbar did the best to lower the temps. It kept them in the reasonable 240s in Las Vegas traffic in the summer and quickly dropped them on the open road. In fact the crash bar got so hot disapating heat that it melted the paint and some of the plastic on the lower fairings. So I'll probably wrap those contact areas when I do it.

[HDDOC]

Thanks for the reply, was thinking to reduce the plumbing maybe just run the engine gaurd cooler also to get less restriction on the oil pump. Have you tryed just the engine gaurd cooler and what temps did you see on hot days. I used just the engine guard cooler set up on a 10to1  95" motor and it would keep my temps on the 220s.  Thanks Doc

Spugin Oil Coolers still exsist there in Las Vegas NV... Rita took over the reins after her husband died... I have 2 of there Polished Coolers on my 04 Road Glide... They work awesome...

I mounted the Spurgin Oil Coolers on the engine guard and my lowers still fit without any problems... The coolers are in unrestricted air out on the engine guard...

[IBARider]

Heat transfer in a parallel arrangement is more efficient as the heat transfer from oil to air is proportional to the temp difference. In a parallel arrangement both cooler see the same high inlet temp.

Hmmmm so let me get this straight.  Just for argument sake... say each cooler has a 15 degree temp drop.  In parallel... same temps in, same temps out for both coolers ... that would be 15 degree drop... total.  In series, it would drop 15 then another 15 for 30 degree total.  I know that's an illogical approach to logic, but it does have some merit... In parallel, the oil is flowing slower so there would be more of a drop than the 15... but not 30...

And being more restrictive in series than parallel does have merit for these new fangled TC oil systems where the coolers are before engine rather than in scavenge side.   For any system, it would put a higher demand on pump, but I'd much rather have that on scavenge side than engine feed side......

Do you have any pics of your set up?

[Big Dan]

Ken,
Did you plumb it like that per the manufacturer's instructions? The only reason I ask, is that I was taught as a young Steamfitter apprentice to never "bullhead" a tee when plumbing for any type of liquid. According to what we were taught, it should really be plumbed like my really bad Microsoft Paint drawing below. Of course, if the manufacturer says to plumb it like you did, I'd just stay with what you have. But if they didn't, you may want to consider changing it. What happens (according to our training) is that the liquid will "short circuit" and possibly even alternate between coolers. 

Not trying to stir the pot here at all, just sharing information that may be helpful to you. The installation looks great.

[Ken R]

There weren't any manufacturer's instructions.  I just did it on my own.  I do know that "bullhead" T's can cause liquids (or gases) to choose their own path, but the oil flows at such a slow speed that I didn't think it was of any consequence.  I assumed that both coolers have about the same resistance to the oil flow and it didn't matter if they weren't perfectly flow-balanced. 
I tried both ways, but the tubing didn't work out in the space provided very well when plumbed as you drew. 
Y's would have been better if it mattered. 

[hotroadking]

Ken could you make that image a bit larger my 42 inch plasma screen still has a few feet left to fill up.....

Oil cooler from HD worked great on the 124

Probably put one on the RG

I wonder about HD's mounting them in front of hte regulator and inbetween the rails of the frame,

Seems the front tire would block air flow to some extent to the lower mount and the oil cooler it'self would
slow the air down going to the front of the motor on the softail mounts even heat it up...

Hanging them out in the breeze is probably better... ugly but better..

[HDDOC]

Anyone think that a pan temp in the 230s* is high?  Thanks Doc

[Rokinrider]

I ran a Tru Cool tranny cooler on my 00 when I rode to colorado a year ago. It was very cheap and worked really good. I normally run an old Lockhart sportster cooler unless I go on a long trip then I go for the larger one. Tru cool makes alot of different sizes and they are well built and light. Jeggs and Summit sell them. Worth a look!!

[Rokinrider]

 I am curious. Is it better or worse if you don't run the adapter or just run the lines back to the engine before it dumps back into the tank? I run an adapter because I want to cool my oil before it enters the engine. I have a friend who swears it runs cooler the other way, WTF. Just wondering if there is any data to prove if it even matters. We all want as much temp drop as possible IMHO. 

[Big Dan]

Rokin,
I can only relay what I've read from various manufacturers of coolers, but it is my understanding that it is better to filter the oil first, and then cool it. Everything I've read says that hot oil not only flows more freely through the filter, but also filters better.   

[IBARider]

Anyone think that a pan temp in the 230s* is high?  Thanks Doc

For an evo... yeah.

My '02 TC would run 230-250 when it was 110+ ambient. Dry desert air results in higher combustion temps than you wet folks in the southest...

My '08... I'd love to see 230 in the pan.  I bet it hit 250 yesterday and it was bout 90 ambient.  I've seen 300+ in the pan when it's over 110... that was with oil cooler and XIED's

It is cooler the other way around but only because of where (oil bag?) it's being measured... think bout it.  You cool your oil before engine, it heats up and you measure temp in bag.  He heats oil in engine, then cools it and then measures temp in bag.  It's all the same temp going into both engines... right??  but go ahead and let him think he's cooler.....

So,  i should prolley add at least 15 to my '02 stats above to equally compare... but these new 96 TC's with '02 sensors are definitly hotter!

[iclick]

Anyone think that a pan temp in the 230s* is high?  Thanks Doc

I would consider it high if the bike was moving, although HD considers it "normal."  Normal isn't necessarily ideal, however.  I've seen 230° several times in two years, only in summer while in stop-and-go traffic, always below 210° while moving.  I consider this acceptable.

One of the reasons I am considering going back to the crash bar oil cooler is that it was the BEST method for cooling my bikes' oil. Even with my dual oil cooler set up, the temps were in the upper 200s and bordering 300 while running hard across the Mojave last summer. Then again my bike has always run hot oil temps. In a couple of weeks I'll probably pull the Spurgin and go with the crash bar and the 10 row.

[xzo124]

About 3 weeks back I put a Jagg on the frame down tube. Already had Harley's premium low cooler on it . Should have done this years ago , much better....xzo

[Paniolo]

About 3 weeks back I put a Jagg on the frame down tube. Already had Harley's premium low cooler on it . Should have done this years ago , much better....xzo

Which brings me back to the baser matter of the situation. I often think that the oil cooler down low is blocked by the big fender and this does not get the proper heat exchange from a steady breeze. The ONLY time it dropped the temps below 250 is when I rode in the rain and the water provided liquid cooling on fins. I would like to run one on the down tube, but with my old style lowers there is not enough clearance, hence the Spurgin. On the other hand the crash bar is ALWAYS in the breeze. I'd like to see pictures of the Eastern Performance oil cooler with lowers to check out the clearance.

Anyone have a Davern Machine cooler? No internal fins. I bought two of theirs years ago for my 118" FXDL, but never got around to mounting them. They also sold [and I bought] a bypass block that mounts between the case and the oil filter mount. I can't remember exactly how the plumbing was routed to/from said block.

The Davern's look similar in design to the ebay Eastern Performance ebay coolers shown earlier;

Internal fins vs no internal fins?: I would think that there would be a big difference in cooling.

For plumbing simplicity, the filter mount with internal 'stat used on some of the SE bikes works nicely on bikes that can use it. I used one of those on my FLHT. One line to crash bar, one line back.

Boy, Mark.  When in the rain, my oil temp drops to 170, the thermostat temperature.  Before the thermostat, it would drop down to maybe 150 in the summertime when rainy.  Much of the cooling is probably due to rain on the head and cylinders, I think. 

I've seen high temps of 285 or above, but that was either dead stopped in traffic while it was over 100 degrees, or during parking lot practice.  The motor didn't seem to care as much as I did.  With the oil cooler, I can practice longer between cooldowns and the cooldowns are shorter.

By the way, I don't think it takes much air through the oil cooler to get to maximum cooling capacity.  20mph will just about do it.  30 for sure. More wind through the core helps, but not as much.  The internals of the oil cooler can only transfer so much heat from the oil as it passes through.  There's wind behind the front wheel.  Probably plenty.

Here's another oil cooler for consideration.

Let’s wrap up our air flow treatise with a look at a product that uses air flow for a much different purpose than making more power. Rather, it’s designed to dissipate the heat that powerful engines generate.

Most oil coolers on the market don’t control oil temperature. They only cool it, and they do that only when you’re moving. Yet your motor needs cooling just as much (if not more) when you’re stuck idling in traffic.

There’s a new oil temperature control system soon to hit the market called Ultra Cool that actually controls oil temperature. It has three components: a regulator that allows oil to circulate through the cooler only when it reaches a temperature above 160 degrees (needed for warm-up to allow the oil in the engine to lubricate properly); a thermostatically controlled, high-output fan that pulls air through the oil cooler when the oil temperature goes above 210 degrees and automatically shuts off when it drops to 190 degrees (and works even when you’re standing still); and a cover that keeps out debris.

I recently had the opportunity to install one of these coolers and frankly, I’d buy it! It promises to do something long overdue in the motor cycle arena, and as the attached pics hopefully show, it’s not bad looking either. I can’t (yet) attest totally as to the functionality of the Ultra Cool, because my “lab rat” is a on a ride through Russia (yeah, Russia!) as this is being written. However, aside from the fact that I have a couple of issues with Ultra Cool’s use of a Jagg’s adaptorâ€"which can (without due care and caution during the in stall) later come looseâ€"I’m certain it works as adver tised. Mind you, for all I know those critical thermostatically controlled fans are off an old desktop computer. Nonetheless, this is one of those “Why didn’t I think of that” improve ments over anything else on the market. For those who already have an oil cooler, factory or aftermarket, the story goes that Ultra Cool’s creator, one Marlon Moss, is also going to offer an upgrade kit to add thermostat and fan where none came before! For more information, you can visit the website www.ultracoolfl.com, or just give Marlon a call at 831.207.3394 and he can explain why a cooler that works independently of “natural” airflow is really an oil temperature control system!

The point is, whether you want your Harley to run “hotter” or keep its “cool,” ya gotta go with the flowâ€"air flow, that is!

My $0.02 - but late.

If you figure out you (want) double coolers - then make the connections after the tubing diverts to and from each cooler exactly the same to avoid a difference in oil flow between the coolers.

Parallel coolers will be a much lower pressure drop than a series connected pair.

Twin coolers will have double the oil side pressure drop no matter what - and the ones with 'turbulators' will have even a higher oil side pressure drop. The connection at the base of the filter is another pressure drop - as is a stat.

Coolers / accessories I have seen did not have no real performance data available so oil side pressure drop, estimated air flow, entering and leaving media temperatures, etc. are all ukn.

Selection must be your best guess or from the results of others.

Maybe this is more like $1.02.

Shutting up now.
