Subject: [FlyRotary] Re: EWP
don't see any EWP on cars yet as a means of regular cooling,
except racing. I know they sell them aftermarket for that too now, but I don't
see any longterm experience yet....
You
have to remember that auto manufacturers won't spend a penny more
than necessary on their cars, and EWP's are going to cost more than the basic
pumps that have been used since the dawn of time. As long as
they're working, and cheap, the auto manufacturers have no motivation to
improve the product. The same goes for aviation. Why do you think
we still have the same antiquated Lycosaurs in
production?

I smell pizza)
Rusty,
I know auto manufactures will
always try to get away with the cheapest, but they're giving each other one
hell of a competitive time, so they still have to get some
reliability.
What I stated somewhere else
on this list about not seeing EWPs on cars yet: I ment I don't see them on
regular production cars (yet), so there is not any bigscale record on them.
Paul will try to proof me wrong in a moment ( I hope...), as I really would
want to learn more about EWPs.
But to get to the point,
Rusty I believe here we are comparing 2 different things: EWP against the
belt
Now if I change the factory
WP against a good aftermarket WP, we can start to compare! Meziere against
Meziere or something like this....
I believe the car
manufacturers would use EWPs at least on their highend models and/or show off
models, IF there would be any advantage:
The highpowered topend models
of any of the car makers struggle with mpg values, a price difference of 150
bucks (or whatever a mass produced EWP would cost) would be cheap to
increase mpg even a little bit.
Mazda could use a couple more
horses on their RX8 to get back on their initial claim.
These are examples where the
price would be secondary to their image.
On heavy equipment,
18-wheelers, they definitely would use EWPs if they could make better
mpg/power.
I doubt that the price is the
real issue. Nearly all new cars run E-Fans today, because these really do
bring advantages, even most if not all big rigs run electric fans today (
though I admit I don't know, yet, why my '02 Toyota SUV with a Turbo Diesel
still came with a beltdriven fan...)
To your Lycosaurus
question:
Answer is: Absolutely crazy
certification costs combined with absurd liability laws. Even if you can
improve them, as Superior proofed quite well with their XP Engine series, it
still will cost half a fortune to STC any improvement. I am waiting since 12
years on the promises of any of the big magneto makers to bring electronic
ignition and variable timing to the masses. However if the manufacturers of
the engines don't make the electronic ignition standard equipment, this will
keep me waiting a while longer... And they won't do that as long as this
involves recertifications and more STCs.
Point is, in cars any
innovation shows a LOT earlier than in aviation (if it is related in any way,
like cars and planes use both piston engines).
Electric Fans are here since
what, about 15 years or so? If EWPs would have that much of an advantage they
would be here since a while too. Obviously the electric motors hold up - on
the other hand IF they fail you still can make it home without the fan,
not without the pump (Except on the Cadillac Northstar engines
:)).
Car makers still seem to
trust the belt more than the electric motor..........

Just because something is new
it doesn't mean it is better than the old and proofen.
I am questioning the proposed
advantage of the EWP - Proof me
wrong!!
