    Powerful 12" Pusher Fans

    If any of you out there need pusher fans because you have some crazy turbo(s) behind your radiator there's isn't as many to choose from as pullers. I've been running a set of Spal's pushers for years (rated at 3300 cfm total) and they did OK but when it was 100+F outside and I was in hard core stop and go traffic (or climbed the local mountain in 5th gear) they could only hold the temp at 194-196F but they couldn't drop it.



    I switched to a pair of Derale 16925's:

    They're rated at 4300 cfm for the pair. I really love Spal fans so I was a little worried about this possibly being marketing BS from Derale but I made the jump anyway since these were the best fans I could find (spec wise) that would fit. When I got them out of the box I was happy to see Bosch fan motors on them. After the install let me tell you...these guys work significantly better. Not only does the "hands in front of the IC" test approve the car also cools off noticably quicker once they kick on. The fans operate alot less often (194F on & 183F off). They're not as thick as the old Spals either.

    The bad news is they pull some current so you have to build a decent relay/power system to feed them (IE not stock). The good news is they come with relays and thru the core mounting straps right in the box.
