GNSCOTT, don't you mean IAT #'s? Inlet air temperature.
In order to do a real, accurate, and fair test, it has to be done in a windtunnel, not on someones car. Most cores out there are already flowed, so you just need to know what they are using. Spearco cores are already flowed at 1.5 pressure drop and the #'s are available by them. I believe the pte is a spearco core. Someone out there probably knows if this is correct.
Just by core size, the V1 is 25x14x4.5 and the precision I believe is 18x11.5x4.5. The CAS is already at an advantage on effeciency due to the core area. And the precision I believe is a spearco core, not an extruded tube, or the newest in core technology tooling. So for someone to say that a spearco had an outlet temp of 115 and the CAS at 180 is not even close to what is already out there and what I have seen in the import world where spearco cores are the main intercooler. A spearco 2-216 core at 28x10x3.5 is only 74% effecient, a core area bigger than the pte. And it flows only 790scfm@1.5 pressure drop.
Dequick has a supra intercooler at 24x13x4.5. It is 94% effecient at 1500 cfm with 17 mph in the tunnel. It flowed 1015scfm@1.5 pressure drop. THIS CORE IS SMALLER THAN THE V1!!
THAT CORE IS ALMOST IDENTICAL TO THE V2!
only a .5 inch difference in depth.
The same cores are in the V4 and V4r, just smaller.
If we are going to start to get somewhere with all this, we need real #'s, or these threads are going to live forever and everyone will just go with what they bought and say how it ruled.
