Looks awesome! I’d like to see that write up, do you have a link?
The only drawback is the single motor arrangement puts the fan motor right in front of the water pump pulley, so it would have to be pretty thin. That’s the nice part about dual fans, keeps the thickest part of the fan assembly away from the tightest clearance. But if it’s thin enough at the back of the motor that would be a great set up.
Yes, but not everyone fully rewires their car for this. I haven’t. I run an amp gauge bypass and have my fans run off of relays but it’s all tied back to the stock harness.
I’m not sure your comparing apples to apples with the fans. Fans can be rated at start up or at steady state. The start up amperage is much higher than what they pull when they’re already running. With a 4 amp rating I seriously doubt that’s the start up amperage.
You guys are just silly. They make electric airplanes now, think about that for a second.
If a mechanical fan can cool a particular engine, so will an electric fan. All you have to do is match the cfm output of the mechanical fan, and all that comes down to is blade and shroud design and the amperage to the motor. The mechanical fan and shroud can already do it, so really it’s just matching the power and speed requirements with the electric motor.
Now, there might not be an off the shelf electric fan that will meet the requirements of your particular system because of the dimensions and power requirements, but that’s not the same as saying an electric fan can’t cool it.
Also a nice set up! The other one that works for 22” radiators is the older Ford Taurus set up, I forget the year range. But I think the HHR fan is a little thinner?
