Extreme/expensive mods to gain milage in (turbo)diesels

[Baltothewolf]

Why not go veg conversion? If you can find a few local restaurants to donate the payback would be way, way faster due to free fuel! You would only have to run on diesel until the the veg gets up to temp (or install an electric heater inside the veg tank).

. . . he does have to make sure his injection pump is up to the task. Most modern common rail diesel systems run at far too high a pressure to accept even a small thickening of the fuel that results in a disastrous increase in rail pressure and immediate failure of the pump.

I'm gonna second on that. You could consider to get an Elsbett vegetable oil conversion kit.

That is an interesting concept. A 2tank system for me would be good.

But the problem is our goverment.

If on fuel, no matter what type it is, isnt payed accins over it. You can be caught and get a huge bill.

If you buy ppo with accins payed on. It cost a littbe bit MORE then regular diesel

So thats a no go for me.

If it was cheeper the fuel. Then it could be good.

But its not.

Yes. Waterinjection is an option and for around 300euro I can install a 2 stage waterinjection.

First nozzle when i hit 1.5 bar boost (=max)
Second nozzle when i go over a certain rpm.

What are the gains?
How much water do i need to carry with me?
What type water do i need?
- tap water?
-bottle water?
-filtered rain water?
-destilled water?
-...
What pressure do it needs to run?
What size nozzle?
...

Is changing the final axle ratio feasible? Perhaps from another model of the same make car? Larger diameter tires? Is your car a rear wheel drive or front wheel drive?

Its a rear wheel drive only.
It has a 4.27 final drive.
I was already looking for a diffswap. Holding both options open: changing transmission ratios, or diffswap.

There is a 2.7l version of my model. But that has independand suspension in the rear where my model has a solid rear axle.

The 2.7l rexton has a solid rear axle with a 3.31 diff in it.
Sending emails to persons whe can answere the question. Can i swap those diffs?

Also found a complede rear axle of the 2.7l rexton with 3.31 diff. So maybe i can swap the hole axle... Who knows...

I think 5.5L/100km (42mpg US, 51mpg Imp) is pretty good for that size and shape of vehicle! There are limits to how economical it could ever be made.

Gearing would be the best bang for buck, I expect, and the least unpredictable. Is it lowered already? There's supposed to be an aero gain in that.

Yes. It does get pretty good milage
It is not lowerd. Bit it had a partial lower air dam. Made it myself :P
