There seems to be some confusion as to how the side mounted intercoolers get the airflow to go through them.
Keep in mind the Michigan car was an ACR with the foglight covers making sure that no air goes through the foglight openings at all.
That car's AIT's on the hot days we drove it were not noticeably different than another car that has the foglight openings open.
On stock car with stock wheel well openings, the foglight openings are low pressure because air cannot flow from the foglight opening to go anywhere but to a closed off wall.
With the front wheel wells modified to accomodate the flow of air through the cores, the foglight openings need not supply even one CFM of air to go through the intercooler cores.
Once the car is going 30 or more MPH, the amount of air coming into the front fascia's opening cannot possibly go through the oil cooler, AC condensor, radiator core, radiator fans and radiator fan shroud.
The excess air normally builds up in the core support without the modifications made to Carl's wheel wells has nowhere to go and adds drag to the front end of the car.
All that pressurization now has somewhere to go through the side mounted intercooler cores like Carl has.
P.S. Carl, you are doing one hell of a fantastic job!
