David,
I've been trying to understand what the driving experience is really like
in a diesel(TDI??) powered Westy....more particularly a Syncro Westy.
Haven't had the pleasure yet...but like to...(Karl,....are you out West??)
I can easily understand all the discussions about the big torque numbers
being available at low rpms. Sounds great, especially in a Syncro Westy.
But I'm curious about tranny longevity in a Syncro?? So many speculated
here that there would be broken tranny's everywhere when a 3.3L Subaru with
200+ft.lbs available...(although only at high rpm)was installed into a
Syncro. What about that "weak 094 tranny"....what happens when all that
torque gets dumped into it while launching a 5000lb Syncro up a steep
incline or out of a ditch or some sand.
Secondly, I'm curious about freeway cruising. With "rubber gearing" (29"
tires )you said you were cruising at 3000 rpm. What's your cruising speed
at this rpm.
If the goal is to be able cruise freeways at 70-75mph or pull a freeway
mountain pass with the other traffic at 70 mph,is that reasonably possible
in a diesel. If so, what gearing and rpm will a diesel (TDI)require.
