I believe this will be my final update to this thread. I have substantially changed my set-up in the last month, so any further updates won't be accurate for this modification alone.

During the last 2.5yrs of running these fans, I have averaged about 15-15.5mpg with mixed driving in the Denver area and surrounding mountains. I won't lie, it's mostly in town and Hwy driving for work. Just to be clear, I typically run my Disco fairly empty, no back seats, and just my tools for whatever job I'm doing at the time, as well as hauling around whatever fits inside. This average is across seasons, and across that entire time period. The only change that altered those numbers during that period was a fluid change from overly thick Diff and T-case fluids to the Redline Lightweight Shockproof fluid. That change bumped me up about .5mpg. I also moved my temp sensor to my CARRS4X4 brand 4way coolant tube (epoxied it on), which sped up the reaction times to keep a near perfect temp range. No more sluggish reaction times with the sensor being on the thicker aluminum of the water pump.

The recent changes I have made to my Disco are an Electric Power Steering pump, and eliminating about 100lbs of unsprung weight with a lighter wheel and tire package. I am seeing a preliminary 2+mpg increase with just the EPS, before changing out my wheels, so I'm excited to see where my mileage goes after having cleared my adaptives and running a few tanks of fuel thru it. I will report further MPG findings on my EPS mod post, so if your interested, subscribe to that one, link in my Signature below.

Happy Modding!!!

 

Can't wait on the electric fan kit.

 

That'd be a cool idea! I'm more of a creator than a business person, so I wouldn't know where to start doing that kind of thing, but I'd be happy to work with someone who has the skills I don't. Kinda hope I don't see someone offering a kit without my participation tho... that'd feel pretty awful, wouldn't it?

I should add that I do have multiple other lil projects I'm working on with this Disco that will also likely be helpful to others. Could do an EPS kit as well, you wouldn't believe how much it positively effects the performance of this rig.... But I'll always post up my projects here, so everyone can benefit, and we can all learn together.

As Always, Happy modding!

 

Which EPS did you go with. I was thinking to get the Volvo one at some point.

I also saw a motortrend video where they were talking about electric water pumps - apparently another 20hp goes to move coolant around.

 

Check it out, I've done a whole write up about the EPS, and others added info as well to make it a fairly informative thread, IMO.

I have also seen, and am interested in the Electric water pump, but they are extremely pricey, so I have not had the funds to go that route. Most of the stuff I do is in an effort to save money, and do things cheaper and more reliably than an OE repair would do. So far, an Electric water pump does not fit those criteria...

I can say, that the assumed 20+HP I have gained from the E-Fans and EPS is extremely noticeable, and I am seeing gains of 4-5mpg. I had a long time LR mechanic drive my rig the other day, just to see if he could notice any difference in mine versus others he drives daily.... and he was all but flabbergasted at how much more responsive and nimble my Disco is compared to any and all others he has ever driven. Felt pretty good that

 

Best way to design things imo. For the user by the user.

 

Should have a dual electric fan kit on the website by the end of the month. Finishing touches on the install video now.

 

Wow, well that does feel pretty awful for me now doesn't it......

 

Well don't feel too bad, yeeaaarrrsss in the making literally. Been running a dual electric on mine since 2014. Kit design and production takes longer than most people think if it is going to be fully plug and play and suitable for the less experienced. Otherwise you get 30 question with every kit about everything from wiring to mounting etc. Will include mounting bracket, auxiliary fuse panel with relays and brackets, bolts, screws, fan mounting brackets, everything but the fan. Does NOT use the Fusion fan for reasons that will be clear in the video blog post. Fusion is a good option, just not quite as good as the one I use based on fit and airflow. Honestly the entire thing has taken me way longer than I intended, been telling people privately for months that it would only be another 30 days and things kept getting stretched. So I guess we'll see...

 

I've never investigated this so this is just off the top of my head, but I'd be very skeptical of that claim (that there is anything to be gained by switching to electric); power steering only applies a substantial load when you are turning the wheel, coolant is pumped ALWAYS. Even with the thermostat closed, you need the coolant circulating throughout the block and heads. There might be 20hp required to run the pump, but you don't get that back by going electric, you just convert it from mechanical load of the pump to electrical load of the alternator, which becomes mechanical load at the crank pulley. In fact, it is more load due to the losses involved in generating and utilizing the electrical energy.
