Reply to "Pantera Cooling System"

THe simplest way to get a brass rad is to take an OEM unit to a rad shop and tell them to build you something that fits inside the OEM frame, which is soldered to the core. That way you'll be certain that it fits. I suspect there are also still some vendors that sell brass rads (possibly built exactly this way). I did this 18 yrs ago (4-tube copper core from Detroit Radiator) and it worked fine until I added the aluminum Fluidyne and Flexilite suckers. The aluminum rad upped cooling power immediately (15 degrees lower water temp), and I lost 25 lbs of weight off the nose. The old D-R unit with home-made shrouded dual sucker fans is available.....
The biggest problem with aluminum rads comes from the quality of water in your local area, even with a 50-50 mix of antifreeze. Fluidyne says that some East Coast water is so acidic, they replaced one Pantera's rad twice in 2 yrs from internal corrosion. Now, Fluidyne ships a bottle of No-Rosion with each rad. Sacrificial anodes work, too. FWIW, my Fluidyne from PI Motorsports is going on 8 yrs old on NV water with zero trouble.
