    Like many of you I purchased the 2G FAL 325 (flex-a-lite) fans back in the day and bolted them to a fluidyne radiator thinking it was going to be an upgrade and to make room for my FMIC piping. Unfortunately, my main (condensor) fan died after 14 years of faithful service and FAL wanted $150 for a replacement motor. Let's be honest, the FAL fans are not impressive and I could never run AC in the summer without overheating in GA.

    Time for an upgrade!
    So I went out and purchased a Spal 30102038 12in Puller Fan PaddleBlade rated at 1640 CFM after eyeballing if it would fit behind my J-Pipe. Turns out if you take your time with a dremel, you can actually get it to compression fit into the original FAL shroud! I'm pretty sure I can squeeze one in on the driver's side if/when the AC fan takes a dump. If you have FAL fans, this should be on your list of things to do. With the main fan only I can drop from 210 to 203 in about 1 minute or two of running at idle. Turning both fans drops the temperature to 190 very quickly.

    Test fit:

    Cut the dead fan out:

    From the backside, align the fan so you only have to remove a small portion of the shroud and mark it:

    Cut the reliefs to allow the fan to push into the shroud. Note that the sanding attachment worked better than the cutting:

    All done. Note the new fan is simply compression fit from the back of the shroud. I did not use any bolts:

    Fits great!

    Now how do I program the Link to turn the fans on when I want them?
