Enclose the bottom of the front end; most of the suspension is hanging out in the wind. preferably add a complete underbody that is smooth.
Even an NA diesel should get better than 5 mpg; fix that thing! The fuel system likely needs a *lot* of TLC to clean it up.
A turbo diesel is like a turbo gas engine; for a given *power* range, the turbocharged smaller engine is more economical for light duty use than the larger NA engine. If you already have the power you need, it really won't give you much fuel economy improvement to add a turbo. You would need to swap out the current engine for a smaller turbocharged one to see big gains from a turbocharged diesel.
How much fabrication are you willing to do to that cube?
Edit: Also, check your alignment. It probably isn't that good. |
your kidding. that looks like the top of a camping table ;~| actually i want the flat wall in order to establish a status quo mpg. then i will fit a slanted board, and then a rounded capsule all existing objects i hope to find.
then the duct and if it shows promise i will marry it to a carefully designed
cabover bubble.
yes to front end tray. it has twin i-beam, very busy design. from cab back i am going to clean up the frame and even remove the cradle which housed the slide out moving ramp, delete the 30 gal cube fuel tank in the rear blocking airflow, generally streamline frame members as much as possible, add a tubular rear bumper (it has none) and attempt to give it a favorable trailing edge.
wheel pants for the dualies but instead of side skirts i am going to encourage more air to flow towards the center of the underside to generate mass flow for this hybrid diffuser idea which will hopefully get the duct motivated!
just doing the injectors should bring it up to 10 mpg
a properly designed turbo system can be used for power or economy - your choice. i have some tweaks in mind for my turbo vehicles that will utilize turbos aftercoolers and water injection in a whole new way.
wont alter the cube shape, will add to it though. ideas?
alignment like EVERYTHING else on this vehicle is likely in a state of disrepair.
thanks for the tips
