There is a 3.7mi stretch of I25 between ABQ & SantaFe known as
La Bajada (The Hill) that climbs 688ft & takes roughly 2.96min¡¯s @ 75mph
& with the OEM 3rd gear & 235/75r15 tires I ran on the rear of My 90Westy
the EJ2.5 has handled that quite nicely @ about 5400rpm possibly 100-200
times over the past 14years with many of those having Canoes on the roof &
or Raft Trailer in tow,,, Those times when VDubaru is Bare & Lightly loaded @
about 4400lbs & there happened to be little traffic I would push it to 82mph @
about 5900rpm ~ I now have 235/70r16s on the rear & do 75mph @ 5600 &
82mph @ 6100 ~
These little 4Bangers are actually quite happy @ High RPMs as long as
They are Properly Lubed & Cooled & Properly Built ~
A point to remember is that there is Less Friction between 2 surfaces
the faster they are moving relative to 1 another ~
There is, though, another daemon to keep in mind about Your Subi
powered Vanagon,,, When connected to a drivetrain, Revs/Min translate to
Revs/Mile & due to the higher Revs/Min We generally run Vanagons @, the
Subaru recommended 105000mi T¡¯Belt change interval should be reduced
to roughly 87000 miles on a Vanagon like Mine that has a taller 4th & Big
Tires on the rear,,, Those with OEM 4th & ¡°normal¡± sized rear tires should
change the T¡¯Belt @ Even Lower Milage & the amount of time spent driving
in lower gears also can reduce T¡¯Belt life even more ~
