BF-
Somewhere I was using an on-line calculator which you input all your ratios and your wheel diameter and desired engine rpm-
Fixed so you can vary any one of those so you can run your engine at its most efficient rpm range while hitting you target road speed.
If you need that page I think I have it favorited somewhere. Seems like I heard someone say that the "sweet spot" for the 6bt
is around 1800 RPM.
I am also shooting for good MPG. Not quite on the road yet. (overhauling my rear end)
I have 93 6bt,ford intercooler with stock 6bt turbo- 6 speed Ford ZF-6 manual (2 range with 4x4) in a 2004 leaf spring F-350 -
currently have 35 inch wide mud tires. May go to 18 inch wheels and a narrower tire.
Hope to get 20 + mpg My pump has been turned up about 20% (supposedly) Seems to have plenty of power driving around
the yard. I can really feel the turbo pepping things up when it gets above about 1000 rpm. It has the 18 cm H1C so I was
expecting a delayed response. It has enough power I may consider turning it down just a hare - but I wont decide till later when I can
test MPG on the road.
I just saw a device on youtube which you add that allows you to adjust your fueling electrically via 2 potentiometers in the cab while you
are going down the road. Says it works on first gen too !
www.powerdrivendiesel.com called the in cab fueling adjuster-
maybe someone here can tell us if it has been tried and how good it worked-
