With the stock size tires it holds speed on the highway just fine. With the
207/75's I need to step down on it hard to get it to hold speed. Not that
it won't do it, I just have to step on it harder to get the same result.

I think the issue is the 9psi. I am not sure what the power difference
is but it is noticeable in the seat of the pants.

11 psi is the max for a 617, but 14 psi is normal for a 603. You
will get a bit more power at 11 than at 9 on a 617, but you will get
greatly accelerated engine wear above 11.

Yeah so I've heard. I have the Garret and if I do it it will be
when it's out and replace the bearings and seals at the same time.

Yes but output efficiency does not equal fuel efficiency. This was about
fuel efficiency unless I misread something.

This was in MB literature somewhere, referencing 75mph. I was being a
bit more precise (anal? facetious? trolling?) as it would make sense
that the car would be setup for 120kph. This would be with stock tires
of course.

Efficiency increases with boost. So fuel used to cover a
distance can actually _decrease_. The efficiency curve

I always figured you wouldn't get peak efficiency until you hit maximum
injection timing advance. Usually with 60x and 61x engines, the spec is for the
timing to reach full advance somewhere between 1800 and 2200.

Remember the more boost the more fuel is
68mph I would guess. 2.88/3.07*120kph. The was in a thread I read quoted
from MB, I think this is not over all MPG but bang for buck assuming
time and diesel costs money.

Remember the more boost the more fuel is being burnt. Ideally you want

I don't like the long-legged gearing on my 85. The engine is
running too slow at low highway speeds. (Best I can remember.
The tach is still dead) The turbo isn't really working much
at 55-60 mph.

If you do a lot of 75-80 MPH driving and very little 50-60, it
might do fine.
I was thinking the 85 gears would get me better fuel economy at highway
speeds. Maybe at the cost of worse mileage overall if the turbo isn't
spooled up enough at average travel speeds.

I doubt that had any effect on the axle shaft. It carries no
load. And if "overloading" the car caused shaft failu
I do not know who that is.
Having more fun, found the right cv shaft is bad so I am learning how much
fun it is to swap over the older style shaft from my 78 coupe into the 83.
Not really too bad of a job to do. I see no issues with running an old
style shaft on one side and a new style on the o
