We used our good friend Paul’s 2018 ATS-V to test and validate the new C&R intercooler cores. Paul runs the full Purple Belt Performance Package, and he was the first ever ATS-V owner to run nine second quarter miles passes in the True Street category.
Our ‘before’ tests were done using the stock intercooler cores, at 76° with barometric pressure of 28.89. Engine coolant temperature was 181° at the beginning of the pull. Manifold air temperature started at 120 degrees and ended at 116°, for a decrease of 4°. Peak boost with WGDC of 99% was 26.4 psi with peak power of 636 whp.
‘After’ tests were done using the C&R intercooler cores, at 79° with barometric pressure of 28.88. Engine coolant temperature was 180° at the beginning of the pull. Manifold air temperature started at 122 degrees and ended at 111°, for a decrease of 11°, which was 175% more than OEM. Peak boost with WGDC of 99% was 25.9 psi, with peak power of 638 whp. This was 0.5 psi less than with stock intercooler bricks. Boost is a measure of restriction, so this proves the new cores are less restrictive than OEM. The most interesting data point of all was when we compare IAT versus MAT at the end of the dyno run. For the stock cores, IAT was 85° and MAT was 115°, or 30° above intake air temperature. For the C&R cores, IAT measured 90° and MAT was 110°, or 20° above intake air temperature. This is a very significant performance improvement.
In summary, we found these cores to be a nice improvement over OEM, in every category we could measure using our DynoJet 224xLC dynamometer. Considering all the above data, we believe these cores will perform very well on the street and at the track. We envision less heat soak, lower MATs and reduced knock retard for every ATS-V and CT4-V Blackwing owner!
