This test holds up on the street as well. A drop in IAT as soon as the power is applied with it either slowly leveling off, or a very small rise. This intercooler is doing work.

Kind of hard to compare when all the cheap intercoolers are no more then 3" thick, I wouldn't use those eBay intercoolers over 700hp

The whole point of this exercise was to show you what can be gained when you go from the generic 3-4 inch core E-Bay coolers that are found on many builds, to a quality (and yes larger) core that many are skeptical of spending money on. I too was skeptical and wondering if this costly upgrade would be worth anything. But, I did it and wanted to share the data.

Although for the most part, when the cheap units only cost around $100....it is kind of hard to overlook them, and they do perform ok in a lot of cases.
But as you say, for a few hundred dollars you can get a much superior unit that will yield better results everywhere.
One area that I think always fails with the cheap units is end tank design. Although the cores are poor, I reckon they would perform far better with a much more open end tank design.

Some more data for this thread. Here is an actual low 9 second pass down the 1/4 for review. You will note that the ambient was over 100 degrees at the beginning, and the average over the pass was 87.6. You can clearly see the IATs take a nice dip as the car starts moving (and meth is spraying) with a slow increase over the pass. IATs never went as high as ambient.
