[DeTomaso] Cooling system

    I bought a couple Ron Davis super speedway radiators that were new, but originally sold to Richard Petty.  Dennis Antenucci has been using one and I kept one.  Dennis was really happy with his.  They are BIG single pass radiators.  Single pass reduces the resistance to flow which some have found to cause cavitation at high RPM in the water pump in a Pantera, and the larger volume increases coolant dwell time in the radiator.  The bubbles created by cavitation reduce cooling at high RPM where you need it the most. 
    There is an article on the Stewart Components web site on radiators:

which says:
"Double pass radiators require 16x more pressure to flow the same volume of coolant through them, as compared to a single pass radiator"
    Since a Pantera already has a long coolant path, it seems like a single pass radiator is a better approach.  I'm not sure if the radiators Ron Davis makes for PPC are single or two pass, does anyone know?

  I'll give a third positive in the Ron Davis radiators that Dennis Quella sells.  I've installed at least a dozen of these and have never had one fail, ever!!

After a long run on I-90 I did an IR check at hose in front of surge tank, reading was 170 degrees.  Bud #3400 ( Drive it like there is no tomorrow -- for there may not be ! )
