Message: [QUOTE="jdgleason, post: 1122194, member: 166"] So, I've always seen mixed reviews on intercoolers, so I figured it was time that we got some solid data on one. Peter from Alradco was all about helping make it happen, so we came up with a game plan to get some good solid info on this intercooler doing what most of us do with our trucks :D Started off with a raw intercooler from Alradco (no coating or polish) and Nathannial and I went to the track the first evening I could! Obviously we were at Bandimere, and Density Altitude was 8700' or so that night. I made 3 passes, and datalogged each pass. Each pass, I pegged the EGT sensor, so it's tough to say how toasty things got lol. I tried to stay consistent and my best pass was 12.3 at 111.67. Anyway, here are the slips and the Intercooler after we swapped it! To recap - Peaks were: EGT: 1760+ :lookaround: Boost: 69 Psi 12.3 @ 111.67 [ATTACH=full]145813[/ATTACH] [ATTACH=full]145814[/ATTACH] And here's a video of one of my stock intercooler passes. Pay attention to smoke output. [url]http://www.youtube.com/watch?v=YeVq8y_xuP0[/url] Swapping the Intercooler was smooth... really no hiccups aside from 1.) I forgot a 10mm socket somehow, and 2.) The brackets for my lightbar were in the way a little bit. Everything lined up perfect. On to the good stuff! Now with the intercooler I made 2 more passes and datalogged each. I was shocked at the results. The truck picked up almost 2 tenths and almost 2 mph! Running the MPH through the calculator shows the truck picked up 33 horsepower :eek: [ATTACH=full]145815[/ATTACH] [ATTACH=full]145816[/ATTACH] [ATTACH=full]145817[/ATTACH] Looking at the datalogs for these 2 runs, peak EGT's were 1691* and 1680* and boost was 71 psi. Looks like a drop of 160+* EGT's and 2 psi more boost with the intercooler! Additionally, smoke output was lower... you can see in the video how much quicker it clears up.

I confirmed that over the next several days of driving, EGT's seemed to stay 50* lower than with the stocker. On top of that, my truck looks much better with an Intercooler behind the grill!
