Pantera Intercooler
Just me or is that intercooler setup all show and no go? First, the intercooler is a bit small. Second, the airflow is nearly worthless since the intake is so small and behind the curve of the roof.
Just check out the intercooler location on the F150, or any hot hatch with a 4 banger turbo and you'll see the type of airflow that is needed to really do the job.
Add to this the complete lack of rear visibility the terrible hacking involved to add the thing and it's sadness all around.
