with air-to-oil coolers, and it works great. The thermostat keeps the cooler

First, my earlier comments were geared towards more traditional air/oil
coolers, where the sole function of the unit is to reduce oil temperatures.
You don't want to do that when the oil is still cold, hence the need for a
thermostatic adapter.
Realize that the Laminova unit is not an oil cooler. It is a water-to-oil
heat EXCHANGER, meaning that its initial job (and maybe even its most
important job) is to heat up the oil (since the water increases in temperature
faster than the oil), and only after the engine is working hard, does its role
reverse and it then sheds engine oil heat into the cooling system. By
using a thermostatic adapter, you would be negating what is arguably the
greater fuction of the Laminova unit. A non-thermostatic adapter should always
be used with these things (and as a bonus, it's substantially less
expensive).
Chris Difani and I have looked hard at the underside of the Pantera, and it
just doesn't look very practical to mount the Laminova in the place of part
of the under-car water pipes; there just isn't enough room, and the oil
lines would be dangerously vulnerable from below. However, there is a ton of
room behind the radiator (even with a stock stand-up design), and it will be
a fairly simple matter to replace a portion of one of the pipes that leads
from the radiator to the under-car pipes, with a Laminova unit. A pair of
hard lines (rather similar to the brake vacuum hard line) will be routed
alongside the water pipes, with short flex hoses connecting the lines to the
cooler up front, and the engine adapter out back. Earl's fittings will be
used throughout.
We're working on designing a complete package for the Pantera; we've got s
ix or eight coolers, which I've dismantled and thoroughly cleaned out; Chris
is machining them to accept -10 fittings, replacing any tired seals, and
then pressure-testing them to ensure their intregity. After the Reno event,
my car will serve as the guinea pig, and once the concept has been proven, a
complete kit will be offered up for those who want to follow suit.
Johnny Woods and Geoff Peters in the UK have already spoken for two of
them; Stephane Bergeron in Paris has also taken two, and Charlie McCall is
getting one but only with the proviso that I have to fly to Spain and help him
install it. :>)
