SV: absurd pressures figures was: atomization enhancement

[Gustaf Ulander]

List

As a fellow Swede I feel I have to back Fredrik up here.

http://www.audi.com/java/models/stage/technic/v6tdi/e_v6tdi.html a link to
Audis TDI homepage, 1500 bar.

Trust us, there IS no typing error, in fact, those high pressures has been
discussed in european magazines for the last 3 years.

Questioning information given is sound, but I feel we're passing the limit
of being plain stubborn here...

I have a hard time believing that all the magazines "and" the Bosch
handbook all have the wrong numbers. And the Bosch handbook says
pressures between 350 and 1600 bar and I have a hard time believing you
can make a typo like that. It's also hard to believe that 3-4 different
independet automotive magazines would make the same typos.
Even a harvester machine use up to 200 bar in the hydraulics system in
steel braided rubber hoses so I don't see why these figures would be so
hard to achieve in steel lines.

Just my opinion....
