[DeTomaso] Radiators

[Mad Dog Antenucci]

Good points Ken....... but it is not surprising to me that this radiator and cooling system mods work so efficiently at 'high' speed as it is that it all works so well at SLOW speeds in traffic with NO fans.

  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.
