Looks great! I have a friend who works in a fab shop who is going to make me one from the CAD drawings you sent me. I'd be interested to see some pics of the final install and get your impressions of any improvements in air flow or function.

I did a temp install with some 5/16 EPDM seal on the shroud to the Rad..
wired strait to battery, Fans run great, no vibration at all..
primary fan is pulling a little air through the secondary fan, but not much at all, used a dollar bill to test air flow..
dollar bill will hardly stay on the secondary fan, so its not pulling much air through it....
Primary fan (on Pas side) will suck a dollar bill to the a/c condenser everywhere but the far drivers side with just primary fan running and this is with the top plastic Rad cover off... which is a big open 4" gap between the tops of the Rad and a/c condenser
Still not sure a divider is needed, I'm quite sure it will cool just fine as it is....
but I may cut a divider out tomorrow evening (if I get home early enough) and tape it in (just for test) to see how much air flow improvement it gives... I'll keep it 1/4" from the fins on the Rad... no chance of rubbing fins and would still have some cross flow of air...

Ok, back to bussiness.... E-Fans
Well, retested the fans with a (Taped In) center divider, put it just under the shroud mounting flange and this will give you about 3/8" from the fins on the Rad once a 5/16 EPDM seal is installed on the mounting surface.....
A notable air flow increase from Primary Fan, but hardly any air being sucked in the secondary fan with just the primary running....
I would have to say there is enough increase in air flow and decrease in sucked air on the secondary fan to warrant a divider strip, so I just faded, drilled and painted one I made out of .080 Alum. going to lay a strip of EPDM in the center and bolt top and bottom with it press hard into the foam... I can see this being a big time vibration peice if not installed right...
For any one else making one of these shrouds, just have the fab shop weld in a drivider... if you want one in it....
Will install in shroud tomorrow night and update a few pics for any one wanting to add this the the design.......

Very nice, I need to take a metal shop class and learn to weld! What is a good class to take (we have all sorts, TIG welding, MIG welding, etc). I am wondering which trade will best benefit me in auto fabrication and auto repair.

Hi.
I'm making mine out of marine-grade plywood.
> REAL Easy to work with/cut/drill
> Requires no welding or welding courses
> Relatively light
> Sealable/paintable
> Cheap
> Material has self-dampening acoustic properties - no vibrations.
> Have a chit-load already on-hand
> Canada has LOTS of trees
Cheers!
