Little performance feedback from a pull after work tonight. This was a 35-100 MPH pull after sitting in some traffic. Outside temp was low 70's, boost was 13.5psi.
Looks to have dropped temp during the run. Wow. Most likey as the truck went faster, the intercooler gained efficiency and worked toward ambient temps for the charge air. Pretty impressive heat exchanger and look forward to track time.

People don't understand how bad those e-bay intercoolers are until they do a back to back test. Changing nothing else, I saw a guy pick up 8mph in the 1/4mi. going to a Spearco core. We tested temp outputs and pressure drop and the pressure drop was identical but the output temps were night and day different. Simple test is if your intercooler is not 90-99% efficient, you can do a lot better.

Here's some more data. The first log is a track log. Before burn out intake was 88 deg. At the end of the run I was pulling timing because it was over 140 intake. This was on a 55 degree track day. Running this core on a 90+ summer day would be a horrible plan to prevent knock.
The second log is off the streets, around 70 outside, best I got logged was a 1st-3rd gear to around 100mph. Temps started at 91, got to 84 mid pull, finished at 86 in third gear at 100MPH. Still going down on average. Very happy with it and now I can put timing back in my map up top. Also this is pretty much a engine saver for top end knock when engine temps are at there highest.
I'd bet at the track I will be around where I started or within 2-4 degree intake, start to finish. Old core shows 60-80 gains when you include burnout.
