[DeTomaso] Radiators

[Ken Green]

I've been reading about intercooler design, and at least one "expert" said you need to recess the core or the air just goes around it.  He said you get more air flow through a radiator a few inches behind a small opening (like 1/4 the radiator frontal area), than through a radiator that's not recessed with the entire face in the air stream.  

I guess you might have to look carefully at how the air flows around and into the nose of Dennis's car to really know why the radiator works so well at high speed.
