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

[James Murray (QB/EMC)]

Thanks Ray, you're install job is super! but the core must be very small in order to fit the tanks? Not sure what's the better core, a vertical flow or a fin and tube design... The vertical flow will flow better (no back pressure), but will it cool less than the the fin and tube or bar and plate (or is that true)... 

Yes, you are however correct 3 inches is the limit to fit behind a bumper and it would require moving the PS cooler line above the A/C condensor. Ideally I would like to find a core that would fit under the bumper rebar and not so close to the A/C condensor (better air flow). 

Ray, how much did you pay for your Vertical flow IC and where did you buy it from if you don't mind me asking...

Cheers, /James.

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...
