Like the title says, I bought a 1981 300SD for an event called the C2C Express, a run from the Red Ball garage in New York City to the Portofino Inn in Rendondo Beach, CA. It's a throwback to the days of the Cannonball Run, and as such, only pre-1980 cars are allowed (iexceptions are granted, like my '81).
We are placing a 32gal fuel cell in the trunk, so we will have a total capacity of 52gal or roughly 1,000 miles at ~20mpg. We would like to keep around that number if possible.
We have access to a few local junkyards with plenty of cars available, so taking upgraded parts off other cars to put on this one would be awesome!
I have talked to a fellow W126 owner, and he suggested a few things (EGR delete, cleaning out the plumbing). I was hoping to get a list if items that I can do to free up some power WHILE not drastically decreasing efficiency.
We have only a few weeks to do all of our upgrades, so low hanging fruit is ideal.
