collection of intercooler fin pictures (ic insides and outs)
http://www.socalevo.net/forum/index....152.msg6953886
i found the cspec pics i needed... can we get inside pics and outside pics? i requested the ebay and stock close ups on outside already
also requested a member for arc ic pics..
see how those pan out

You can learn some good things on that Nisie video but it does leave some important stuff out about intercooler design. Pic up any book about turbocharging and they all say the same thing. It is better to have a short cooler with many rows. Than a longer cooler with less rows. Unfortunately on the evo a side to side cooler is much easier to plumb up. And most people just dont like the look of a top to bottom cooler. Another thing I have noticed about most aftermarket coolers is end tank size. large end tanks do nothing but decrease turbo response. Short routed IC pipes make for a responsive setup. Here is a pic of a sweet intercooler.
The other thing they leave out is that the inside turbulator design can be too restrictive. When you have a restrictive inside core desgn it becomes more important to have more rows like the top to bottom cores. The more rows there are the more the air slows down. Giving more time for heat to transfer. Everybody and their brother has made a pull in the car and jumped out to put their hand on the cooler. Everyone notices the same thing. Only the first few inches of the cooler will be warm. I have been wanting to do a top to bottom core on my evo but everytime I go out and measure it up it gives me a headache trying to figure out how the upper IC pipe should be routed.

more stacks means more air slowing, shorter bars means less distance
compare this to
more stacks means more lag, shorter bars means less lag.
just simple equations that "we" have to work with to keep spool up and cooling in their optimized places.

There are two things that effect lag. Volume. And internal restriction.
so lets compare a 10 x20 to a 20 x 10. They both have the same volume. But the top to bottom has less restriction and more time for the air to give up its heat.
I believe back in the day, Extreme Turbo, makers of the MUTT turbo also made a VERY VERY VERY nice Top to bottom FMIC core that fit a DSM easilly, so I would immagine that you could revise it to fit an Evolution simply by flipping it.
RRE sells one for a 1G DSM, I am sure they can flip it to make it work for the Evo.

just a recommendation for anyone wanting to contribute here... it's a good idea to take fin pics in macros (the flower) on your camra. this allows you to zoom REALLY close up (what macros means) and not get any haziness from funny fucusing.

wooo i just updated with the arc outside... now i just need pics of inside!
