So, I was really tired and distracted yesterday and I left the keys in my truck with acc on, so it's super dead. I pulled the cables out and rolled the car up to it (2008 Kia Rondo, LXV6)

While I was under the Kia's hood I looked at the E-fan.. it's HUGE. Way bigger than the HHR fan, and it's a two speed or possibly variably controlled by the PCM, I wanted to see it's airflow so I drove it instead. When I was done driving I checked and it blows A LOT more (as far as I can tell) than my HHR fan and is offset further to the drivers side too so it will clear more of the pulley system, which is one thing I'm worried about with the Hemi swap.

Looking on ebay shows them to be twice the price of the standard aftermarket HHR fan, both brand new. That would be worth it to me to have two speed control and much more airflow. It's a bigger fan too so the natural airflow will be better at highway speeds too. It's also half the price of a brand new Mark 8 fan.

Anyways, I'm going to look into this more and do some measurements and decide if I want to buy one and try it out. One problem might be startup amps if I try to run it on high only to keep my current controller, if it flows like the Mark8 or Taurus then I will need a different controller.

 

So I measured it, 25x20" and the fan opening is 17.5" so it's a lot like the Taurus fan but the shroud looks like it would be easier to work with than the square box that the Taurus fan has.

 

Interesting, wonder how much juice it pulls compared to the Taurus fan...

 

That shouldn't be too hard to check. If you know an electrician, electronics tech, or can get your hands on an analogue ammeter and a large capacity shunt (I'd recommend a 100 amp unit, or thereabouts). When you have it hooked up and then start the fan on high speed from standstill, you should see a big very short flick of the needle on the meter, then it should swing down to another high reading for maybe a second or so (depending on how large the motor windings are), and then drop down to it's running amp reading. On the taurus fan, I get a quick flick to a bit over 100amps, but the inrush current settles on around 65 amps for a second or so, and then to around 32+ as the running reading.
