Most I4s can do 6000 RPM all day long if you wanted to.  Find an old 1983 or
1984 GTI and take it for a drive!  The VW Iltis is 4400RPM at 60MPH - I have
taken 1800cc engines to 8000 RPM and have had no problems.  The first 1588cc
motor we used for a conversion ginuea pig we took a brick and put it on the
accelerator pedel and TRIED to blow it up for a little over 1 minute in the
yard... the tachometer was reading 'F' - yes it was down the the FULL mark
on fuel gauge... after a minutes we stopped as it was too loud.  The redline
of most I4s is 6800RPM... remember you are not driving a wasserboxer here!

Hey William,
I bet you'll get widely varying opinions on this, but here's mine
nonetheless.
The syncro tach has a green pie-shaped piece to designate the "safe" range
of RPMs.  The green area goes from 1500-4500 overall.  However, the edges of
the pie slice are hashed green and black, indicating you're getting near the
limits.  The hashed areas go from 1500-2000 and from 4100-4500 (solid green
from 2000 to 4100).  From 5200-5400 you have hashed orange and black, and
from 5400 up you have solid orange.  When running at 4000, I am indicating
about 71-72 mph.  At 4500, I'm indicating about 85 mph.

I also have about 40K on a factory rebuild, and I found that on long trips
(i.e. SFO to Albuquerque and back), running 85 I would use about 1/2-1 qt.
of oil per 1000 miles.  When I dropped it back to about 70-75 mph, I stopped
using oil almost entirely.

Being somewhat conservative about my cars, I decided that VW probably didn't
intend for the Wasserboxer to burn oil in addition to gasoline, and I cooled
my jets a bit.  I don't cruise in the left lane anymore, but I also don't
have as much to worry about on the stopping end either (you're right about
braking).  Getting bigger tires didn't hurt either--a natural way to slow
yourself down <g>.

I am sure the Tiico can easily hit 100mph in terms of power, but you
couldn't pay me enough to drive a stock vanagon 100 mph.

Like Karl, I no longer exceed 4000 unless passing or pulling a hill where I
need a little extra before shifting up.
