Hi Craig,
I have no personal experience with the Fluidyne radiator and have never read anything negative about it.

I think for the majority of ZR-1 drivers doing street duty, it would be better than the Ron Davis radiator. The Ron Davis unit is an excellent radiator, designed and built for racing at high speed. Bear in mind, the ZR-1 radiator is 3rd in line for cool air, behind the AC condenser & Oil Cooler, which have the potential to heat up the incoming air, but always impede the air flow to the radiator. Add to the restriction in front of the radiator, 5 cores of a Ron Davis & you have significant air flow restriction.

As mentioned above, the Ron Davis radiator is made for racing.... no AC condenser or oil cooler in front, so all that high speed incoming air gets used through the 5 cores.

As a matter of economics, if you have the OE radiator, it's clean,in good condition and you are having overheating problems, try 1 hole in the thermostat, or 2 at the most & see how it works for you. A little sweat equity but no real cost.
