Going Electric

The process of going with an electric water pump and fans yielded some interesting ideas.

First off I removed the fan, and OEM water pump to reduce drag, and tidy up the front of the engine.

Part of my reason for doing this was being disabled, and bored... it took me several years to get done a little at a time. The other reason was too many people said don't do it, it will never work, and you'll be sorry. That's all I needed to hear...What happened next was unexpected. I had a lot of extra belt wrapped around pulleys that were no longer doing anything but spinning. So, I was able to remove 3 extra pulleys.... I just needed the right sized belt to compensate... so, with some careful measuring and 3 custom length belts and trips to the auto parts store later I finally had it. The new belt is 4' ft shorter lol, and it reduced some Nano drag on the crank, I hope. I hope the belt doesn't slip, but it has at least 120 deg of wrap on all pulleys.

Just wanted to add before starting this project I upgraded several parts to handle the extra electric load. 1. Mean Green alt. 2. 2 yellow top Ultima Batteries re-located under the bed. 3. Complete re-wire with heavy gauge primary, alt feed, and ground wires with Military lugs, and load center tray.

Any questions, comments, concerns... bring it on!

I would be interested in seeing pictures of your battery setup. What is this load tray you speak of?

Also I see a fleece billet fan pulley in one of your photo bucket pictures. Did you ever run that with your stock fan? Did you have to have a shorter belt? Their website says you MAY need a shorter belt.

EDIT: Just noticed that the picture with the fleece pulley has the electric water pump so my second question isn't really applicable.

Yes, you need a smaller belt because of the water pump and fan pulley is smaller as well. The billet pulley is meant to be run without a fan. Wait, maybe not. I guess you could still use the fan. it would be a shame to cover up such beauty though!

Since you don't have the resistance of a fan or a water pump I bet less belt wrap on pulleys will be fine. If you did have trouble I would bet it would be on the crank first. Maybe in a tight spot making the powers steering pump work while the AC was on? I guess you'll find out and let us know.

Load center is just where I ran the lead wire off the batteries up to the engine bay connected to a solid copper bus bar rated @ 600 amps continuous load. From there I just ran a small wire to the fuse box, starter motor, and alternator, and the rest can be used for dozens of accessory hook ups.

I did this to a HEMI race truck.

I had rules to follow to stay in a class of racing. To "free" up power I converted to a electric fan and electric water pump. It made a huge improvement, mostly on launching. The engine could span the RPM range a lot easier.

I have "thought" about doing this with my Cummins. I've decided to not do it, mostly for reliability reasons. I'm not sure if would make enough of an improvement on a torquey engine with a much lower red line. On the race HEMI, I would hit just over 7000 RPM. So from ~700RPM to 7100RPM is a large range. The quicker the engine would go from idle to shift point 7100, the better. However, with a non race Cummins, you only have ~700 to 3100 RPM. A much smaller RPM range.

I'd be interested in how you perceive the improvements. Example, easier leaving a light, or faster shift points..




On the belts. I did research on belt contact. You'll note some belt driven devices have 3/4 pulley contact, and other may only have 33% or 50% contact. If its a high strain device, like an AC compressor or alternator you will note 75% contact with pulleys. Most cranks have a very high belt contact. Look at other engine belt routing, you start to see a common design on contact patch.

I realize it might not work if the belt slips I'm ok with that. it's just something I wanted to try before putting it all back together.
