[QUOTE="Catmonkey, post: 15612199, member: 124025"] Actually, it's what you should be seeing. What most don't realize is when the boost by-pass is open, which is mostly idle, cruise and light throttle, air is going directly into the intake manifold and very little airflow is going through the intercooler. When the boost by-pass slams shut on heavy throttle, air is forced through the intercooler. You'll notice the three small inlets in the smaller section of the top of the intake. What sits above it is the by-pass throttle blade. [ATTACH=full]98679[/ATTACH] Here is the inside of the intake with the intercooler removed. You can see the ports at the very top of the pic is the route from the by-pass section. [IMG]http://www.collectiblesanyday.com/jpg/311455556491_1.jpg[/IMG] Now, this is the inside of the intake manifold with the intercooler in place. [ATTACH=full]98680[/ATTACH] You can see from the pics that air coming in through the by-pass ports is going around the intercooler and doesn't have much change of getting cooled by the walls of the intercooler. The walls of the manifold are quite hot. The longer you drive the hotter it's going to get. Bottom line is monitoring your IAT2 temps while you are at idle or cruise speeds isn't a very effective way to measure your intercooler system. The true test of the intercooler is to monitor what the IAT2 does when you open the throttle and get into boost. [/QUOTE]
