ANYONE USED THE FEULING OIL COOLER WITH THE EXTRA FILTER? PROS/CONS-APPEARANCE ON BIKE?

[Ohio HD]

I don't think it uses two filters. I think it just comes with one to use.

[HDBill]

It has it's own filter in addition to retaining the stock filter. Would like to know if anyone has this set-up and any information on performance and appearance.

Bill, are you aware of exactly how that "cooler" is made?  It is basically like an old time cartridge filter where you take the end cap off, remove the cartridge, clean out the canister, and install a new cartridge.  Most of the industry abandoned those contraptions back when I was a youngster in favor of the spin-on filters.

Since you still retain the regular spin-on filter with this Fueling "cooler", you basically have two filters.  Why would you think you need two filters?  As for the "cooling" feature, if you look at this thing closely you'll see that it's just some fins on the outside of the filter canister.  You can buy similar finned add-ons for your spin-on filter.  Trust me, this thing isn't going to do a whole lot of oil cooling, especially when compared to a real multi-row heat exchanger like the available cooler from H-D or better yet the 10 row cooler from Jagg.

I stand corrected, I glazed over that detail. 

[HDBill]

GOF, no I had no misconception as to construction or any advantage to an additional filter. Being mounted away from the engine on the fork tube wanted to know if anyone actually HAD one and if they thought or KNEW of it adding any COOLING.

Cooling is all about surface area that the oil comes in contact with. The one with the most surface area in contact with the oil and sufficient surface area for the air to contact it on the other side is always going to win. So it becomes a balance of restriction on the oil side versus the cooling your trying to achieve. To much restriction on the oil side does more harm than cool oil can help.

[HDBill]

 I agree with you as to surface area and assume you are meaning the additional filter being restricting. On that point I do not see much advantage to the filter. It may remove more contaminants, but I feel unnecessary. The housing though being mounted to have more air flow over more area, how well does it work. Also finning dissipates more heat which is also the function of the finning on the Jagg coolers. Secondary function of the original filters is also for cooling. I have used the slip on fins and seat of the pants saw no difference but have seen others claim 20 degree difference.

[Steve Cole]

I have no idea if that addition filter causes restriction. My point was that you have to be careful when adding things into the oil system. I have seen guys trying to run two oil coolers end to end and have issues. As the oil cools it gets thicker, thicker oil is harder to move, so you always want to filter oil when it is hottest just for that reason. This is just like the cars 30 years ago! Everyone kept adding oil coolers only to find out that it hurt more than it helped. If I remember correctly I think it was Mazada that did a study on oils and what temperatures they work best at and then came out with a cooler that had a built in thermostat that put the oil in bypass until it was at the proper temperature. If I recall the magic number was 220 - 240 for proper oil temperature but that was long before synthetic oils. I think the synthetic oil moved that range to 200 - 280 but it would be best to look it up for the oil you are running.

In racing we use 0w- 30 oil to qualify with as it buys us around 5 HP in a 800 Hp engine (as we fight hard for every HP) but then drain it out and switch to 15w - 40 for racing as the engine will not last on the 0w oil for an entire race, just too thin. So there is always trades and you just have to be careful of the limits. The fin area has to also contact the oil if your thinking of increasing the surface area, many people miss that part of it. You need more oil in contact with the cooler part than less oil contact and more fins to the cooler (air) side.

We are pretty much on the same page. Here is how I got here. I have a 10 Wide Glide and a 12 Fat Boy. 96 and 103 both with stage iv 103 SE race kits 58mm TB, high flow injectors etc. Now a 14 CVO Breakout with SE pro upgrade. Ambient temperature here in last of June - mid September 95-110. Being concerned with engine longevity figure heat is my enemy. Reading forum threads on component failure, 110 mostly, have been looking to add cooling fans and oil cooler. The Fat Boy seems to run considerably hotter (sop). A good deal of that is perceived by exhaust heat though. Just got a temperature dipstick for BO.is only verification among the 3 bikes. Have seen oil temperature of 235-287. Haven't seen a concrete answer in any threads as what it should be but do not think this is out of line. Anyhow my thought is taking off 20 degrees or so would be beneficial. Let me say these are not ridden as "cruisers". Had ordered a HD cooler but it was damaged and will probably still go that route and Wards fans. Only thing with cooler chrome cover is only held on with sealant but liked it over Jagg for that appearance. So after that long tale is how I came to asking any experience with these. Thinking the "radiator" style is still my best bet. Don't think these mods will endanger me with too low of temperature which I also agree with. After all both are thermostatically controlled. Finning, being oil cooler, heads whatever does dissipate heat better though. The heat will flow from thicker metal to thinner. Add in air flow, cools the thinner metal quicker. We are not cooling the oil rather dissipating heat from it. Same as finning on heads and also realize the same applies here, done too quickly or in excess would be detrimental.

If you want to pull 20~30* off oil temps I would suggest the ultra cool reefer.  I have recently installed one and have seen a 25* difference over the stock Harley cooler.  It has not solved all my heat issues but it is well worth the money. It is the best looking one I have found.

[HDBill]

Thanks, RR. Appreciate the information as to any options out there. They do look good.

I used a Per-Form for years on my 1st TC...a 2000 after oil temps had me nervous. It was basically like the Fueling other than it replaced the stock oil filter. I grew to like the looks, but for oil cooling.............. Na-Da
Getting ready to install a fan assisted, Ultra or Jagg. The Ultra is a good bit cheaper, has anyone did a side-by-side comparison? Can't find the measurements anywhere on line.

Thanks for the heads up on the UltraCool Reefer RR - I'll be checking into this for a winter mod...

I took notes on oil temp before and after for the stock and ultra cool and I found about 25* difference riding the same route on days that where with in 3~4*. Theses where done at around 95* + weather which is where an oilcooler really makes a difference. There was some differences due to time of day, such as sun strength ,  at noon the pavement gives off more heat than late afternoon or early evening.  Each bike has its own personality as too oil temps due to set up with pipes and tuner.  It is cost prohibitive for me to compare the fan assist jagg to the ultra cool.  I just thought the jagg was not as finished looking .  The ultra cool has done a good job of slowing down the heat build up in slower traffic riding, which is where I saw the fastest gain in temps happening.  I had a tts ll Dyno tune done but really did not see a huge change in oil temps.  It does run better though.  All I can tell you is there are better oil coolers vs the one HD install as OEM.  I am still trying to loose another 20* so on a hot day it runs around 220-230*.  I have added a image of the ultra cool reefer installed.
