5154662AC Does appear to be correct 14-15
68059524AL Is for sure supported!
In regards to horsepower we did this test on our drift LQ4 S13 car. The obvious things that can affect the numbers I will provide are: Tiny rack, large steering angle as its a drift car, 275 front tires, 8-10* camber. On the dyno with the stock GM LQ4 power steering pump at 6k RPM with steering at full lock, we ran at 305whp. After removing the pump, we ran at 349whp, with the peak actually pulling back by 800rpm. These numbers are WCF, at 180m above sea level, 8*c ambient.
This is an extreme case test, but this is what we needed to figure out for that specific car. I doubt you guys would see drastic power difference, or fuel economy drop, but I am sure there will be a visible difference. The faster the engine spins, the more the pump is likely to cavitate, causing parasitic drag.
There's a 5154663AC that appears to be from the 14-15 GC as well, I wonder what changes due to the one the one number difference...
Those are some pretty big gains, with some pretty big changes to RPM responsiveness as well, but, of course, it is a race car. Gives me a some hope of waking up this ol' Disco a bit more tho
I see on your site your are doing a bit of testing for some products...if any if them might be able to act as a controller for a set of E-fans, and that kind of experiment and info would interest you, let me know, I very much enjoy experimenting with, and modifying vehicles, and have loved tinkering for over 45yrs. I'd be down for some play time

Good news! I have just figured out the old gen Jeep pumps that FTL was talking about. Doesn't matter when generation or part number of Dodge EHPAS pumps you buy anymore, I support them all!
In regards to helping the disco, I can only guess that it might give you at most 10 more horsepower up top, during cornering. That is just a guess though. Theoretically the gains we saw are really only useful during steering lock at high RPM, so this doesn't usually apply anywhere but drifting.

For the fans, the CAN IO expander is meant as signal and low current driver, so if your efan has a third pin to control it with frequency/duty, then yes indeed it will work! I am specifically looking for people to run the inputs and the outputs with canbus included. If this applies, then yep I'll ship you an initial unit.
Otherwise once I get these 5 prototypes finished and tested I am more than happy to send you one from the second test batch.

That's great news! There are a ton of those 2011-2013 dodge/jeep units on ebay. I'd still stand by my "get the VIN" advice and obviously look for the lowest mileage units (though city dwellers are likely low miles/high-usage). The 2015 Jeep unit I ended up with has ~90K miles on it.

This is right around what I'd guess; based on experience from my drag racing days. The key thing here is, at least in my use-case [D1 w/3.9L and 14CUX (1995 NAS)], the thing only made ~180hp (...not at the wheels either) and about 230lbft of torque. [note: The history of this engine, however small and underpowered, is fascinating, here is a great writeup if you are so inclined: https://www.roverv8.net/specs.html)]
With the current stocker tires I have (235/70/16) it spins ~2500rpm at highway speeds.. I figure 10hp (or rather it's loss equivalent) will be good for ~5% increase in range/fuel-burn. Not big but not nothing.
------------
I did a bunch of tuning on this thing recently and I actually got 17mpg out of the tank prior to the conversion (with a rack on top).. that was ~1/3 in-town, 2/3 highway. It will be interesting to see what it can do on a long highway run now. I will report back on this.
*Did I say how much of a joy this think is to drive in the city now? :-P No pump torture, no leakage no engine bogging... just fantastic.

My fan motors are only 2 wire, so I wouldn't be a good candidate for your experiments at this time. I have been curious about swapping them for a digital motor, so I may have to do more research now. If I had the money, I'd be installing an electric water pump, digital fan motors, electric power steering pump, and electric assist brakes. Sounds like your controller would handle all that pretty easily. Might even be just the thing if I ever Tesla swap this rig, your expander would be an easy way to run all the other systems...don't mind me, I'm just dreaming out loud, lol. That's a great idea for a product tho, I hope it does well for you!

Tuning did you say? Feel like I need to insert that funny meme of Dave Chappelle as the coke head dude sayin, "You got any more o' dem tunes"? But seriously though, can you share any more info in that regard? I'd be interested in hearing what you've done...

I should post that stuff in the Disco1 forum area. I will drop a link here though.
Been running that setup on my 4.6 Disco for a couple months now and it seems solid. Working on making the same thing work with the ACE LS brackets now:
Thanks CaptainAaron. Price is sure nice. Wonder if that will work with my LS conversion. Here is my problem during Electric water pump install. Just need steering pump to move right or hose connections located differently. Any ideas welcome !
The GM pump is solid, especially compared to the Rover pump. The main thing is: I really like how the electric pump delivers max flow at low/no MPH.. even the GM pump cannot do this. Also, the electric pump frees up some hp as well, a paltry few yes, but the damned engine only has a paltry few to begin with :-)
It's been several months now and I still am loving this setup!
Too each their own, the GM pump is great and your conversion looks great as well!
