I know the air isn't 50 degrees, or colder than than ambient air! Jesus, i'm just saying one side felt hot as hell, the other side was cold to the touch, what don't you people underfuckinstand?

I dont understand if you are making a very large exaggeration, or if you were remotely serious about your numbers. This is a technical thread, and you are trying to boost a company's reputation. I am totally behind what you are trying to do, but you would be a lot better served to keep from posting numbers (any numbers) unless they came from some instrument that is designed to measure the said numbers. As Ted suggested, the infared thermometer would be a great idea. They are relatively inexpensive, and I'm sure everyone would enjoy seeing what kind of temperatures you are actually seeing with the core.

Also.. Being cool is good, but flow numbers also matter when making higher power.. SSA copied almost exactly an intercooler from an evo shop.. when put side by side they look identical.. But if you look inside the core design is MUCH different.
It'd be nice to have 2 identical ICs with different cores and go to a dyno to see what the differences are.. Or better yet the track.

I have no flow results, but it does have rounded cast end plates which is best for flow compared to square welded plates. The internal design is typical bar and plate.
Looks exactly like the two air to air intercoolers pictured here inside.

Your statement of cooler than ambient is not correct.. if you said turbo side is hotter than other, I would of agree and most would of also... underfuckinstand??
My other intercooler when i touched both end plates, there was little difference.

jesus christ guys, please stop arguing about this stupid intercooler and how cold it felt and give us some real opinions on the turbos etc.
So far ive gathered:
intercoolers - not bad - any comparisons?
Wastegates - junk - any testomonials from people who have used them?
turbos - junk - again, any testemonials? details please on what happened.

i've used and know people who have used the wastegates...hks carbon copies. never had a problem with them
other than the initial fitment of the manifolds, no problems (and i've installed and used probably more than anyone since all my customers are as poor as i am )
intercoolers. only used 2, but they seemed just fine. 24X12X3 on an fc with a stock turbo @ 10psi only gained 4* during a 4th gear pull to the top. good enough.
never used the turbos before.

The core is going to have a lot less affect on the pressure loss compares to the end take design in this case. With the ASP/M2 or the SSAuto intercooler having similar designed intake and outlet endtakes which are horribly restrictive for flow. I'm surprised no one isn't looking at a formed 90 deg endtake design. With the price of the ASP/M2 unit it should have had formed elbows.

Not true at all. <o:p></o:p>

It's not ideal but I don't think you understand where pressure drop really comes from; it's not for the most part turbulent flow but actual bottlenecks. Yes turbulent flow can reduce flow but not at the levels you seem to be talking about. It's primarily a function of the size and number of charge rows in the core. I personally think from what I've seen that the Chinese core might not have such a bad pressure drop because it doesn't have any "turbulators" and has very low fin count (low density) on the exchanger surface area. The downside is it will likely have really crappy efficiency of thermal transfer, which is the purpose to an IC. <o:p></o:p>

You need to reacquaint yourself with the 3rd gen engine bay I think. The ideal would be large sweeping input tubes right in the middle of the core entering parallel to the core (from the ends) with slow graceful rounded edges and formed ports that line up directly with each charge row, a little like intake runners on a manifold. The problem is there is this big thing called a battery on one side and air intake on the other. Some of the front mounts actually come close to doing this, excluding the formed ports obviously, but then they are kneecapped by having to use long tubing runs with a lot of bends and short cores with very few charge rows which puts you back at square one. To avoid turning this into a book there's simply no room for formed end tanks that will create a real benefit. Anything you could fit into the existing space would cause another problem in that castings need very thick walls and in this case would start to choke things off. I don't know how close of a copy the Chinese unit is but there is, depending on the intake used, less than 1/4" gap between the battery and end tank. You'd have to use a smaller core to fit a smoother end tank which defeats the purpose again. Life would be so much simpler if we had the engine bay of a 1977 Thunderbird to work with but we don't, hence the game of compromises that we have to make in every design, it's a balancing act to try and reach the best compromise for your goals. In the case of the Chinese core a cheap price is one of the primary goals, and it does that very well, but it cuts corners to get there. As I said balancing act, pick which aspects matter to you and in what order...
