yeah, WTF!!!!! every one misses at least a few days.... its a monday FFS!

and so, i made my custom fan shroud today. had my main AL fab guy Justin (nubvr on VWKotex) brake me up some aluminum sheet. then i went and drank some stuff (100 proof crap layin around as leftovers, gotta clear it all out) and fabbed up the fan shroud.

hope you'ns like it. the fan is sandwiched between the radiator and the shroud. i sealed the long ends with foam tyape, but since the fan is flush up to the core it oughta be A-OK.

this is fitment to final, in steps.. hope i give some of you's the ideas to future custom fab work for your own personal projects. as i really like to share what i come up with for ideas, and like to see what others do as well.

from start to finish.

fitting the plate.

marking the opening for the fan.

after first cutout

final fitment

mmmmm nice and SMOOOOOOOOVE......

and flush and stuff. could use a lil more sealer around the corners, IMHO. but since the fan is flush up on the core, it is not an issue. i think its gonna work out spectacularly.

With the shroud there, don't you want the 'inlet' face of the flange flush with the shroud (meaning a 1-2" gap from the fan to the core, or preferably greater)? That way the shroud can act as a duct, meaning that air can be pulled through the entire core by the fan. I would think that with the fan right up against the core there, it will only really be efficient at pulling air for that small part of the core, and airflow through the rest of the core area will now be restricted as the shroud just ducts it into the side of the fan.

yea def move it back an inch or two

Also, you may want to cut large holes in the shroud, then seal it with a sort of one-way flapper, like the stock radiator shrouds. This will allow air to flow out of the shroud when the fan isn't running, but with the fan running they should be sucked 'closed' and still keep all the efficiency of the holeless shroud.

well, i thought of that. BUT; the radiator is a dual pass (the upper half is separated from the lower half) as well as dual row. so all the coolant goes in the top driver side and flows across the full length, then flows back to the driver side lower outlet.

while i understand your guys thoughts, and appreciate them, we must consider this car will only EVER run @ 10 seconds of WOT or less at a time. and it will cool enough. the fan is fully surface mounted and will be sucking air thru the full core height for both passes.

and i dunno, maybe i drank too much tonight, but i think it is the same if not better than the last iteration, which was just the fan mounted to the core with those stupid lil plastic tab things that ALWAYS come loose.

and since it worked fine then i cant see as how this could be a backward step.

and in retrospect, if i need to change it to your guys thought lines, it would not be a big deal AT ALL. but i would then need to seal the corner sections fully. nothing but a THANG to do it, really. pull fan, mount outside with nut/bolts.

we shall see after June 7th....

It looks great, but like Sam said, it is not doing much if there is no distance between the fan and the core. The fan will only cool the small part of the core strait in front of it, and nothing else. In fact it might actually run hotter with this setup because no air can flow through the rest of the radiator.

speeding-g60 · Post by **speeding-g60** » Mon May 17, 2010 8:29 pm

well, then the choice i have is to externally mount the fan, and fully seal up the shroud. not a big deal.

the collective have spoken.

a new bottle (mmmm, liquor) will be ordered for tomorrow, and it shall be done.

i appreciate the "other side" think tank mentality here fella's..... really i do. and i thought the same, but my thoughts tend to run towards the "dual core" and both pass are getting suction. oh well, nothing but a chicken wing to change it. really. but my original thoughts led towards the dual pass theory. the upper half of the radiator is separated from the lower half. all coolant enters the driver side upper and flows to the pass side. then flows from pass side lower to the driver side lower. i think it will work fine as is, but since you guys pose a good argument, i will change it. (its no sweat of my balls doing so

).

40 minutes tops.

did some more load runs.

hit 16 psi in 4th and the tires were spinning 155mph @ 7800 rpm.

sounds and feels EXCELLENT!!!!!and i love how Chub is tip-toeing around out there holding his nose. he said things were tipping over but it was prob the open dumps pushing air....

really cant wait now.
