[DeTomaso] Fluidyne Radiator Shroud

Hi Guys,

At Pantera Parts Connection we feature the Mardyne Fan system, pretty much
the same but better than the Flexilite system. We have designed nice
looking SS mounting brackets for $125 that neatly rivet to the exterior of
the Fluidyne Radiator. The Shroud concept allows 100% of the radiator
cooling fins enabled to radiate heat when even just one of the 1250 CFM
fans is activated. This is opposed to the pusher fans using 1 or 2  12²
fan circles of enabled cooling. With the shrouded puller system you also
don¹t have the fan motor and mount blocking the central parts of the
cooling radiator area at speed. Thus you get more effective radatior
cooling area at rest and at speed.
