They absolutely would, but unfortunately there isn't any room. That's why I keep mentioning that the true AITs are most likely lower than what I am measuring and what I am measuring is worst case which I guess is good for data knowing its not going to get worse right? The pipes are very close to each other and almost touching so there is no room for a sensor in the coupler. If I can get my hands on a Greddy elbow, I can have an intermediate pipe I can weld a bung into to measure the actual combined AIT after the intercooler. The hot side would be much harder because of the bends. I can probably do a 90 degree coupler from the y-pipe and fab up a pipe with a bung for that too. I may tackle this in the future but right now, worst case scenario is looking pretty good temp wise. I'm hoping to hit the dyno within the next month or so once I get the coating done. I'll dyno the factory intercooler, then swap in the new one and dyno that. Same day same conditions so we can see real world difference power wise at least. Then I have the Rmagic ignitor to install to see if that makes any difference. After the dyno, I may sacrifice my Stock intercooler and try to get the temp sensors into that somehow for more comparison.

Big update on the intercooler. I am happy to say that the project is a success at least as far as supporting the stock twins go. I would imagine this would support more efficient single turbos as well. I am going to try to find somebody local around here that would be willing to test this out under much more power with a larger single setup. With the help of @FDAUTO we put this thing through a stress test where it was 97 degrees when we started and almost 100 degrees by the end of the dyno session. The Results matched what I saw with street driving. Even run after run on the dyno, we couldn't get the Intercooler hot. We crept just above 130 degrees even when the intercooler was heat soaked to 130 degrees. The AutoEXE intake gained about 3hp and 9ftlbs of torque over the last dyno session. Conditions were almost identical to the last dyno day so we were lucky to get that data with the dynos being about a year apart. I didn't want to go ham on stress testing the stock intercooler because of how fast they rise but you can see that the temps rise very quickly. I can say I have seen the temps from the factory intercooler in the 160 range pushing it on the street where the new one I don't see over 130 under load even beating on it. You can see in the video how well this performs. Keep in mind, The Air temps are probably lower than my gauge is reading as well because of the placement of the sensor. Thanks to Mike at FDAuto, I will be able to test this theory as he gave me a Greddy elbow so I can now install the temp sensor right after the Intercooler directly in the air stream. Then I can have a sensor in the same place in the intercooler and the pipe so we can see the temp difference.

I am still making small tweaks to the duct mount and working on getting it made in Carbon fiber so it matches the intake. I am also testing different types of Thermal dispersant and ceramic heat barrier coatings on the intercooler to see if we can battle the engine bay heat more and make this thing even more efficient.
