Wasn't someone talking about the 12-16 GPM his EWP was pumping through
his [not running, no EDWP] engine? Assuming 2-3 gal capacity, that
circulates every bit of coolant through the system 5 or 6 times per
minute. That's an entire cycle of coolant every 10 seconds or less.
That sounds pretty fast to me.
Does anyone actually know what the flow through a rotary is
with EDWP? I mean, like measured (the other list can be relied
upon to calculate stuff). Just as important, does anyone actually
know how far open/closed a thermostat is in our applications. I
know some folks don't have thermostats installed. Is it possible that
EDWP might be circulating coolant so fast it doesn't have time to cool
off much in the radiator or heat up much in the block? That the same
system would work as well at lower flow? Or something like that?
It seems to me that all this quibbling about Beemer power levels on the
autobahn ignore the obvious fact that as Leon has attested, EWP works
quite well on the race tracks of Oz. I would hazard a guess that the
stress on the system (WOT nearly all the time, maybe 1/3 the Q through
the cooling system, SL summer temps rather than cruising much faster
(3x the Q) at 80% at much higher/cooler altitudes) would hold a lot
more water than a bunch of Beemer marketing brochures.
The other list is forever making pronouncements about what will or will
not work. Their math is impeccable. The premises they operate
from are not Is it not possible that we are overlooking or
underemphasizing some important factor? That the hybrid (EWP and
EDWP) systems we have online now are distorting the data? Leon's
experience cannot ignore any of the factors. Our estimates can ignore
as many as we want to (or are unaware of). I can't help but think that
a little morel hard data gathered from a purely EWP system will put a
lot of the controversy to rest.
A flawless line of reasoning, based on a false premise
leads us right through the lookin' glass ...

Al, How
about 100mph for 20 minutes on the autoban?

Ah-h-h-h;
you’re getting close now. That‘s probably about 80% power. But you’d
probably have to stop once to pay a toll, and slow down for the Opal
that’s driving in the left laneJ. Or
maybe they don’t sell the EWP version in Germany.
