the results really blew me away.
The alfa will now be getting an electric fan

Personally, I wasn’t a fan of this one.

Sadly, E-Fans and Corvairs don’t seem to mix. They overheat on the highway. Way too much back pressure.

US-market MGBs went from 62 to 67 horsepower in 1978 when they got an electric fan...

It bugs me that the manufacturers of the fans in the video still make the blades flat or with sharp bends, specially surprising with the plastic fan since that’d be made through injection molding. Airplane propellers have airfoils, which are much more efficient at moving air with less drag. Even the curved blades on a typical electric radiator fan are much more aerodynamically efficient.

I watched this this morning and the 02 will be getting an electric fan as well. I need all the HP I can get.

This just adds actual numbers to what I discovered a while back when I swapped my OE steel fan out for an e-fan on my old S-10. While I’m sure I didn’t free up 30 hp, since it had a smaller 4 blade fan. I wouldn’t be surprised if it was around 15 or so, which made a drastic difference when you only had around 90 to start with.
Also my hypothesis as to why the fan in free air robbed less power than the shrouded one. It was because the shrouded fan is forced to draw all of its air through the radiator which is a restriction, so the more RPMs go up, the harder the fan has to work to pull air through it. The unshrouded fan is pulling air through the raidator but also drawing air from the sides which is easier on the fan, but drastically reduces the effectiveness of actually cooling the radiator.

That is absolutely the correct reason.

I was previously considering swapping to an electric setup on the Eagle to save weight and gain a bit of power. I have to to do a bunch of wiring for the fuel injector conversion anyway. But I started leaning towards just being lazy and sticking to the fan it has for now... Figured it wouldn’t make that big a difference.
But my fan looks REALLY similar to that steel-fixed in the video. So parasitic loss is probably similar as well. Adding electric fans back onto the list. I’ve got the room for a bigger alternator if I need it.
