    I finally finished the write-up of my fan shroud fabrication. It's fabbed from aluminum sheet to fit two SPAL electric fans in a big-block radiator application. Lots of pics and descriptions of what I did. Here's the link: <a target="_blank" href=http://community.webshots.com/album/27011877IJsJEhiyEn>Fan Shroud Fabrication</a>.

    I'd like to give credit to BobK for the inspiration. His write-up is what gave me the idea. This is my first attempt to document something like this, so go easy on me.[​IMG] I tend to get into a project and forget to take pictures once I get into the "zone".[​IMG]

    As always, I welcome your comments and suggestions.[​IMG]

    VERY NICE!!!! I have been wanting to do something like that with my electric fans! That is EXACTLY what I was looking for! Thanks and great detail on the write-up! Thanks!
    I'd like to check that out in person sometime as well as your cage, I'm right over the grade!

    Nice job. It looks like you put a lot of work into it.

    How sure are you that it works? I noticed that you still don't have the whole thing back together.

    I'm thinking about taking my fan off to see what the noise/power benifits would be with electric fans. It's only in the 30's here so I don't think I'd have any problem with over heating on my short 8 mile trip to work. I'm really interested in switching to electric.

    Thanks for the photos.

    Thanks for the write-up. Very nice job too. Let us know how well the set-up works with the big block...

    Thanks! I'm just about positive that it will work. I've done similar setups on other vehicles. The challenge for me is always in the mounting details, and making it fit space-wise.

    These fans will be controlled by my fuel-injection computer, so will only run when the temp reaches 190*, then shut off at 180*. Should be pretty quiet, especially on the freeway, where I don't expect them to run much at speed.

    Hey Robb,thanks for the props .As my wife would say"Damn...that's a tight fit!"Looks like you had just enough room for the set-up to fit in.How thick was the aluminium sheet you used?Looks great,should work well too.Nice job!

    Thanks, Bob! I just used 1/4" thick for the aluminum sheet. I actually just went to a local welding/fabrication shop and they supplied, cut and bent the sheet to my specs. Only thing I would do different next time is to make the sides about 1/4" longer to make a tighter fit against the radiator tanks.

    Looks good, I like the way you staggerd the fans- good thinking. Nice write-up too.

    Looks sharp! I'll probably copy your design when I get ready to go to electric fans on my diesel.

    Keep us posted on the performance of your new cooling setup!

    Twiz, Danno and Slayer,

    Thanks for the kind words about the shroud, especially the write up.[​IMG] That was something new for me.

    I'll let you know how the cooling system works out. Hopefully, I'll know B4 the end of the year. Ya never know...

    "BTW that big block looks sweet too"

    DAMN RIGHT!! The pics do NO justice!! I just went over and met Robb and checked out his Suburban. That thing is SWWEEEEETTTTTTTTTT!!!!!!!!!!!!!! EVERYTHING has been gone through. This thing is just awesome. The cage is BAD ASS. I cant say enough to describe this thing. You'd just have to see it in person[​IMG]. Robbs a real cool guy too! Talked with him for a couple hours!
    Oh and BTW, his idea for getting this beast in and out of the garage is GREAT!! Simple, and VERY effective its seems! Not sure if he has pics of his "custom wheels" or not[​IMG][​IMG]
