[s-cars] 26x8x3.5 FMIC mock up

[Ray Tomlinson]

You can also fit a 24x6x3" vertical flow behind a stock bumper core (very
minor modification), and a 21x6x3" vertical flow behind a stock bumper (no
modification) or euro bumper core (substantial modification - see photos of
my FMIC on s-cars.org), both of which require relocating the PS cooler from
below to above the core (behind the grille).

Also, a 21x6x3" vertical has 30 charge cores, unlike the stock IC, which
only has 15 charge cores, surface area notwithstanding.

For anyone interested in doing a FMIC without modifying the bumper, here's
the space you have to work with...

I wanted to see what the 26x8x3.5 Intercooler I saw on e-bay would look like
so I made a cardboard mock-up, and sure enough it's just a tad too big, it
could fit but I'd have to relocate the oil line in front of the A/C core and
it would be right up against the A/C core (no air flow).

I measured the usuable space that you would have assuming you would not cut
into the bumper:

Smallest space on either side from A/C core to bumper is 3.5 inches but that
assumes moving the oil line in front, otheriwise 3 inches is tops. In the
middle of the bumper, because of the curve, you have 5 inches tops.

>From the top (underneath) of the rebar (bumper core) to the bottom of the
bumper cover you have at max 7 inches (assuming you don't put the
Intercooler Core behind the bumper).

>From the top of the bumper to the bottom of the bumper core you have 5
inches (so the core is about 5 inches thick) vertically.

So a 25x8x2.7 Intercooler would work better than the mock up I made, but you
would still have to have about 2 inches hidden behind the bumper core..

Ideally for optimal flow you would need a core that was 25x5x3 that way you
could mount it underneath the rebar (not behind it) and gain maximal air
flow. You would have more room for a thicker core actually...
Here are some pictures: http://forums.audiworld.com/s4s6/msgs/35209.phtml
although I have to bear in mind the surface area of the original IC is
10.25x8.75 = 91.87 (I didn't measure how thick it was...) while if I was to
go with 25x5=125 core I haven't gained all that much in cooling surface
area, but of course I would gain considerably in cooling from better air
flow...
Cheers, /James "still undecided on FMIC" Murray...
