Heres some pictures that attempt to show the work that was done. The main spot
that took the longest to do was the hand work on the spacer. It was curved outward before and created a choke point. Now it is curved more inward, and the choke point was mostly removed. Other places where material was removed was
at the large corner fillets on the attaching lugs underneath, (shown) and sharp corners were removed where the fan meets the large spacer. If you look closely, you can see these spots.

Mark and Rocco, You are on the list!!
igottajob2- Thanks!! Unfortunately, no price has been set, and there none are for sale at this time, as this project is still in the prototype stage. There's only 2 of these fans in existence at this time, the one on my car, and my other one that my other tester has. His tests have yet to be done, but will provide some very good insights and numbers as to the differences between the stock mag fan and my fan on a 140, set-up the same exact way. When his tests are done, that fan MAY be available
for sale, but it will be custom one off prototype pricing, and will only be of interest to a few that can do what it takes to get the fan to work well for their particular application. Most would be far better off waiting for the production version that has the tweaks needed to work well for most Corvairs,
Being "on the list" is to formally announce that you are interested in being a part of a group purchase, once the price is known. I'm still working on that part!!
In the meantime, in the interest of increasing the output some more for my fan, and doing it in a efficient way, here are some pictures of my latest and greatest bell. It is sized to near perfection for my engine and shroud, and should provide a nice gain in airflow as it is 11% larger than what is currently installed, and taller, which should help the airflow pulley work better.

Nice, its hard to tell from the pics is this a 3d print? You might have mentioned it previously and I might have missed it.

Yes, this bell is 3D printed from high temperature nylon... I don't know how
long it will last. It is supposedly good up to 300 degrees intermittent. I've
been a little spooked about nylon stuff in the engine compartment because of some other items that didn't work so well- but those things were from a "low temp nylon that was not even dishwasher safe... this type of nylon is. I would have liked to have had it made from ULTEM as that stuff is the ultimate high temp plastic. My current small bell was made from it and has proven to be very tough, although it was quite expensive, at least through the place I got it from. The price difference between this new nylon bell and the earlier ULTEM bell was enough that it made for a very inexpensive experiment, and if it holds up long term I'm good, if it doesn't, at least I will have tested the sizing and shape, and will know what material not to use next time!

Wow that ULTEM filament is about 8x the price of standard stuff! But if it does the job....

He Kevin, just a thought :
Would it make sense that the front and leading edges of the holes in the pulley were slanted to better induce down flow through them when rotating?

Please add me to the want list. When ready, the bell, fan and pulley will be parts of one kit?

Bob- Yes, absolutely!... properly profiled, you could get 4 minature inducer/airfoil blades, and it would make the attaching lugs much stronger!!
The underside of the pulley could also have this work done also. It would also make a lot sense for the pulley spacer to to be profiled in a similar manner, and have the base of the fan match the spacer o.d. where they meet. These kind of things are dirt simple to do on a CNC machine, and absolutely evil and time consuming to do using manual equipment, like I did. I designed this one knowing I was going to have to make it, and did not want to
have any complicated multiple set-ups.

1966-Corsa-GT-180, 65180, scottymac, You are all on the list!!!

scottymac- I'm thinking the fan, pulley and bell would be able to be purchased
all in one set, but would like to be also able to purchase the bell and pulley as separate items, just for those that want to mod their cooling system a little at a time, and also because it helps the "tunability" for cooling. Some
might already have a variable ratio pulley they might want to run, others might
want a single fixed ratio that is "right" for their car, others are okay with running the lower shrouds off, and the best set-up for that would be quite different than for those that never take their shrouds off... and so on, so having flexibility for different needs and wants and changing wants sort of favors having these pieces available separately, or as a set.

Heres some shots of the new bell installed- I was so eager to get this thing on
and get some numbers, I didn't bother painting it. The install took a lot longer than I thought, as this thing is so big it created some challenges with
notch clearing for the belt, creating room for the crankcase vent tube, air oil
separator lines and air cleaner vent hose. Once I rotated the crankcase ventilation tube, it took care of the problem, and made all of the other affected line routing cleaner, simpler, and hidden!!

As for numbers, It appears I got an impressive 11% increase in flow (nearly the same output as the 61-63 fan is supposed to do!!), and this increase is basically the same as the % area increase from my little bell to this bigger one. I need to do this test again, more carefully though, as the numbers were absolutely consistent at 1000 rpm, but the gain didn't carry properly to higher
rpms... when this kind of thing has showed up in the past, it was ALWAYS belt slippage. Investigating this further, I found that the belt was god awful loose, and was not any where near as tight as how I initially set it, and I found that the idler stud had stripped and loosened the belt. Now I get to try and fix THAT today before attempting any further tests!
