[Vwdiesel] Brakes --- engine brakes -- ( The physics of it ).

[H.Hagar]

Lee   and all of you  --- this issue was a real , get them brains
to the fore. I for one learned a hell of a lot. And to Mark Shepherd
I think you are right.My landrover going down countless mountains
in bull low  wore the butterfly pivots oval.
If someone claims that a gasser is a better brake --- No  argument from me
only a question . WHY ?.    We shall find out.  Rabbit gasser to Rabbit
diesel on the hill,Both with fuel off.

Val has a calibrated hill and so do I   so when spring arrives ---- we head
for the hills.
Loren said that some Mercedes diesels have a butterfly valve (news to me)
so if we find out why --- it may give the answer. Loren what operated your
Mercedes butterfly ?   I remember your dads Mercedes for its infected fuel
tank.
The alternator can be used as a 1 hp brake for those of us who face long
hills.       say a 0.25 Ohm  1000W resistor   using a contactor for control.
I had that kind of setup on a Landrover 3/4 Ton  --- power routed to a big
Nicad in the back.One big hill and there was power for the outboard
and camping for the night.Loved that electric outboard.                       Hagar.

PS:  In BC a trip down the mountain in bull low could easy take an hour or so.
      2.25L gasser    ---  load about 5 tons. total (trailer).
