i have an intercooler question of my own.....
i'm looking at doing a custom fmic for my car as well. i currently have APR stage 2 (so lets guestimate 220-230hp). i really doubt that i'll be stepping up to a larger turbo, so really i'm just looking for additional cooling for my engine.
i've been looking around for cores and found <a href="http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=33742&item=2418036 143">this one</a> made by spearco. my question is, would this particular core fit my needs without me losing too much pressure/power. if not, what suggestions would you make?
thanks!

I'd get one that's not as long. You're getting nearly zero cooling out of the last bit of tube...
I'd go higher and get rid of some length.
What *exactly* is the vertical height measurement of your bumper cutout on the RS4 bumper Matt?

Likely neither that harmful nor helpful.
But from what I read on Bell's website, you're going to get more lag than cooling from it.
8" is better if you have 8" of airflow in the bumper - increasing the height lets you decrease the length of the tubes, which is good.
I know you though - you just want a shiny metal thing to fill the hole in your bumper. If I were you I'd just wrap a 2x4 in Reynolds Wrap for $6.53 and be done with it. =P

That's very similar to mine....
The 6" high core is perfect for the S4 bumper, you'd have to do a lot of grinding to fit an 8" core.
A 3" thick core is probably overkill for your application though. A 2.25" core using 2.25" piping would probably be ideal.

I bet the K03 has higher output temps than my T3/T4....
I'm guessing the K03 would probably react good to more surface area, but not necessarily more volume.
The longer tubing may be beneficial.

this is what Bell told me when I told them I was runnign a setup pushing around
410 CFM
- to start with.......an Intercooler, considering the usual space limitations, can never be too large; hence, the larger the better (less pressure loss and better heaat transfer).
- a vertical flow Intercooler is better, because the tube-length the charge-air is passing through is usually less than 10", as compared to 12, 18, 24 and longer tubes for a horizontal flow-patterns.
- Assuming the (future) max. flow-rate will be 550 cfm (this translates to approx.365 VHP; Air-Flow divided by 1.5) you will have a choice between a 2.25"x 24"x 6", or a 3.0"x16.2"x 6.0"; both I/Cs would have a total Height (with end-tanks) of 11.0". There are, obviously more options, but these two are the most practical and best compromise between size/volume and performance for this Air-Flow-Target.
I am glad to answer any other questions you may have.
