We've done quite a bit of testing with the Love Jugs Fans.

We tested both the Cool-Master and the Mighty-Mite.

We tested on Air-cooled and Twin-Cooled, both on 2 wheelers and Trikes.

All the tests results were very similar. Below are the results for an Air-Cooled Twin Cam 2 wheeler.

This particular Twin Cam already had many of the cooling components outlined in this REPORT installed, so the temps already were much lower than a factory Twin Cam.

However, as you can see in the Love Jugs test results below, the fans were effective in providing significant additional cooling.

.

There were 5 different tests with each fan type.

The first two tests were a combo, showing what the temperatures got to with the fans off, then showing what the temps cooled down to once the fans were turned on.

All tests were conducted the same day, same gas, same roads, same speed, same wind conditions. On all but the last test, variables were 99% eliminated, to give us a true comparison.

On the last test, stop-n-go traffic, it was impossible to keep the variables even close, thus the slight variance in results.

.

We are not selling these (nor receive any referral fee), but we do recommend them as one of the components in an overall strategy of taming the heat on both the Twin Cam and Milwaukee-Eight. You can see our complete Report on why and how to Cool down your ride HERE.

If you do choose to use the Cool-Master or Mighty-Mite, we recommend you get them at www.buylovejugs.com, call (346) 800-7946 and if you mention that we referred you, they'll put a little something extra in your package for you.

Key to the above chart:

Amb= Ambient Temperature at the time of the testing

CHT= The front cylinder head temperature as measured by the OEM factory sensor, and displayed on the Power Vision as ET

FC= Temperature measured with a heat gun, directly behind the spark plug on the Front Cylinder

RC= Temperature measured with a heat gun, directly behind the spark plug on the Front Cylinder

On the last test, stop-n-go traffic, it was impossible to keep the variables even close, thus the interruption in the pattern of the Mighty-Mite fans being superior in the other tests.

It is readily apparent, in the data below, the Mighty-Mite fans do a better job overall than the Cool-Master, and are Significantly better at cooling the Rear Cylinder than the Cool-Master.

We have our theories of Why the MM's are better than the CM's, but in the end it doesn't matter, they both cool the engine down, and the MM's do it better.

Kevin, Your results are amazing to me given that the Cool-Masters fans are larger in size and the Might Mites. However, the CM fans run at a much lower speed which may account for the some of the cooling effectiveness differences? Do you find that the CM fans are significantly quieter at idle than the MM fans that run at much higher rpms?

What? What did you say?

hahaha, Mary says my hearing is not the best.

I did get other folks to listen to them also. The MM's maybe have a little higher pitch to them. But my bet is that they are very close to the same on a decibel meter. Everyone, not just myself, thought the noise level sounded very close to the same, with the MM's being a little higher pitched.

I think the reason for the difference in the cooling is the placement of the air being moved. I have no proof of that, it is just a theory.

Great data Kevin. This should remove any doubt to those who think that you dont need to run your Love Jugs when at speed, which is just not true. Speed increases the load on your engine, as it is burning more fuel, producing more internal heat, increasing cylinder and oil temperature and clearly the Love Jugs are working.

Rear cylinder heat at speed without the fans is 320 degrees, with the fans, the temp drops to 248 degrees. Thats a drop of 72 degrees. The fans are critical for stop and go, in traffic, but are also a engine saver on the open road as well.

As for the slight difference in the numbers between the Cool Masters and Mighty Mites, the Cool Masters turn at 7500 RPM and The Mighty Mites run at 13,000 RPM, which may be a factor but a very small factor. I have sold quite a few of both the Cool Masters and the Mighty Mites and the reports are very positive on both.

Good info..Do they come on automatic or manual

They stay on whenever the the bike is in the on position if plugged into the accessory outlet under the seat. They also have a manual on-off switch on the fans to turn them off any time you want.
 
They just flat work

I know how well they work ET has dropped anywhere from 35*-45* normal riding. I will not start Old Shiney unless the fans are going along. ride safely Fred:D

Zook,

On the '14, you needed the accessory switch kit to turn on the accessory Deutsch connector undr the left side cover. Is it the same for the '17 TG? I have the fans installed but not connected yet, since the accessory switch kit was not in stock at the local dealer. Really did not want to cut the connector off and wire it directly to the battery if not necessary.

thanks!
 
Also as an added note. I have not been asked by either Papa Zook or DK to mentioned the purchase from them but if you are on this forum and getting input, information and ideas then spend a buck or two extra and support the sponsors and owner.

I would like to also point out that if you are in the market why not consider purchasing from Papa Zook. He will give you a good price and great service. Plus you will help keep this site in business.

I bought mine from Papa Zook and had the same thought when I read the end of Kevin's report. I know he and Randy work closely and share info. It could be that because Papa Z is the founder of TT he did not want make appear he was the only source for Love Jugs. (But when you get ready to buy, click that ad to the right!!)

Before I bought I had questions and Papa Z must have spent 15 minutes answering and explaining the differences between the Cool Masters (which I bought because I like the looks of better) and the Mighty Mites. He told me the testing had been done but had not been published and didn't want me to buy something I would regret once the numbers were out. I don't have any regrets. When I recommend them to anyone I will give out his contact info!

The only question I have about the test is where the temps were taken on the cylinder. I assume it was with a digital thermometer. I shoot mine at the base of the spark plug and don't get that much difference between the cylinders, some maybe 15* - 25* or so, but usually not any more.

Please notice that the link I gave is the same link at the bottom of Papa Zook's post.

www.BuyLoveJugs.com takes you to his (Papa Zook) new site and the 346-800-7496 phone number is his direct cell number. :)

Oh, sorry, I was so focused on letting folks know I was supporting the forum/not trying to take away from it...I did not answer your question.

I use an infrared temp gun to measure the front and rear cylinders. The CHT number comes directly from the ECM...which is a reading from the sensor that is at the back left side of the front cylinder.

When using the temp gun I shoot right behind the spark plug. I use exactly the same spot, distance and angle for both the front and rear... variance in spot, angle or distance will significantly change the temp reading. Also, as little as 20 seconds time difference, after shutting the engine off, in taking the measurement will vary the temp reading.

The difference in front and rear cylinder temps is greater the faster the trike is traveling. Slow moving and the temps even out between the cylinders. If you look at the stop-n-go chart, the front and rear are pretty much the same.

If you look at the ones rolling fast, that is where the bigger differences are...and I did not take my time coming to a stop from speed to get the temps. I stopped as quickly as possible from 75 mph and got the temps right around 30 seconds from when I was doing 75 mph.

Hope that helps.

Thanks for posting this info Kevin. I purchased the Mighty Mites from Papa Zook and have been running them for 2 - 3 months but I do not have a thermal gun so had no way to check temps myself. I have the Deluxe Tank Lift, external breather and Night Rider VIEDs along with the Mighty Mites and a de-catted head pipe and hopefully all of this is helping with the heat issue on my 2015 FLRT.

I can hear the MMs at an idle but once above an idle I can't hear them at all. So to me there is no problem with the sound. The quality of the MMs is excellent and the service from Papa Zook was also excellent. I ordered them and they arrived the next day. I think they are well worth the money spent.

Mark,

Yes, the '14 and up all use the 8 pin adapter plug.

And thank you all for your orders, I very much appreciate it. Both sites are the same source, the new one is just the more modern Woo Commerce ecommerce platform. Eventually all links will go there.

Good points. I have edited my original report notes. The bike we tested on also has quite a few cooling components already on it...that is why the temps started out 40-60 degrees below a factory bikes temps. Still the test shows how the fans cooled it down even more.

Thank you Kevin! I appreciate the info and the time you give here, GREAT info!

I feel what ever choice one makes they will be able to ride happy knowing they have "beat the heat!"

Small price to pay to protect your investment.

:)

Yes, anything we can do to help cool these down will be good for performance, And for engine longevity.

Hey Zook!

That is a 72 degree drop! :)

Your temps are significantly higher than what mine were on a recent ride. I was pulling a loaded Aluma MCT with ambient temps in the mid 80's. My max temps running 75 mph on the freeway were 255 rear jug and 218 or so front. When I stopped for gas I killed it, left the fans running and quickly put the digital thermometer on them (within 20 seconds or so). Temps on the Georgia mountain roads were cooler. 234 max on the rear. I have free flow slip ons, k&n, XiED, and have lower wind deflectors. I took temps in the same location, just behind the plugs.

Those are some nice temps, glad to hear everything is working well for you. :)

There are many variables in what temp readings will show.

The only purpose of my chart was to show the difference between no fans and using fans, and also the difference between the two different fans.

Here are a few of the variables.

Leaving the fans on or turning them off. I turned them off as soon as I stopped the bike.

Type of gun used.

Distance and angle of the gun from the heads.

Location on the heads, even 1/8" difference can result in as much as a 20* difference in the reading.

3 BIG variables will be if it is an air cooled only, a wethead, or an Oil-cooled engine.

I did find that if I turned the fans off as soon as I stopped the temps rose quickly. So I got to where I left the fans on when I stopped for gas. With the fans on and motor off, the temps decreased rather quickly. I also found that the location of the laser dot made a bit of difference. I tried to stay about 1 to 2 inches back from the plug.

Interesting how the MM cooled better at speed. Probably because of the higher rpm which more strongly forced air through the cooling fins at speed, less succeptable to riding air. And the CM did better in stop and go, probably because bigger fans and no riding air to disturb the air flow direction.

Nice work and appreciate you sharing results.
 
Poop happens Ya Kno

It's just me, but I always turn my fans off when getting gas. I'm scared that if some got spilled, the fans could blow it right onto the hot engine. :xszpv:

Makes sense to me I turn mine off also. ;)travel safely Fred

Yes, the rest of the engine is hotter, so when the fans are turned off the heat starts to normalize thru out the entire engine.

I just went and measured the mark on where I measure the heat...it is 6mm, about 1/4", behind (toward the back of the bike) the actual edge of the spark plug.

Just those two difference probably make up the variance in temps.

Ordered the Might-Mite love Jugs

Kevin,

Excellent test report and on that note I ordered the Mighty-Mite Love Jugs from Randy today.

For me It was a hard decision for best mounting hardware, Vibration-Master or Frame Mounting kit. But after a lengthy conversation with Randy I decided on the Frame mount.

Thanks so much for helping me make my decision and your recommendation to Randy, you both have been very helpful.

I agree, great report. And you made a great choice with the frame mount, you will love it! My horn used to shake like a leaf in a hurricane, now it and my Cool Masters are steady as a rock! Randy was right on!

At first I thought there was no way it would fit on my 14, but taking it slow and working it in place a little at a time, wasn't that bad at all! Hardest part was getting the clamps started with my big old stiff hands.
 
I ordered a set of coolmaster's yesterday with the Frame mounting, can't wait to install. Kevin's report plus sending a few messages back and forth with Kevin made me order them.
