[DeTomaso] Difference between an aluminum radiator and one that is black

[Mad Dog Antenucci]

  I'm running a  Ron Davis Single Pass aluminum race rad with the same cooling system mods earlier described by David, Kirby, JT and others. 

Using just a  'Single' PermaCool sucker fan (2,950 cfm) for slow hot L.A. traffic. Temps normally run  170-180F  on the street. Temps will climb to 200-210F in the worst traffic but it takes 15-20 minutes before fan kicks on and then the water temp drops back down to 180 right away.  At WOT in open track or open road racing it will still run no higher then 180-190F and in 2 years it has not run any hotter.

See photo's on TPR web site Gallary.

All nickel-and-dime stuff. The biggest single thing with an aluminum 
radiator is, the water tubes in the core can be as large as 1-1/2" wide by 1/8" 
thick, with 0.060" walls. Copper/brass radiators of any type are constrained 
to an absolute max of 5/8" wide tubes x 1/8" thick with 0.015" walls, all of  
which restricts water and air flow and internal pressures: the paper thin 
copper tubes are extremely fragile and simply cannot handle internal 
pressures much above 12 psi. 
With the DeTomaso Pantera having a 20% SMALLER radiator than a comparable 
engine in a Corvette due to our body lines, we have always been marginal in 
cooling capacity unless modifications were done. As I've said many times, 
I've tried every mod known to man on our Pantera over a 15 year period, and 
nothing changed the cruising water temp more than a degree or two, until I 
added an aluminum radiator. Immediately, water temps dropped 20 degrees. End of
