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?
Rusty (hey, I smell
pizza)
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..........
"Soorry for the wit" - who finds it
offending and/or political.
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!!
