Are you going to do any further aerodynamic tweaks to the front of the truck? It's very square, must be like fighting a headwind when cruising.

I don't have any future aerodynamic plans on addressing the front nose of the truck. Most of my work is concentrating on the rear air flow.

A little bit closer. I'm tempted to paint the belly pan white to see where the air flow/dirt streaks are going.







I wonder if these extra horizontal fins will help any?

Wheel pant installed! I reused the Coroplast from the first version.

Nose view...


Rear view...


I ended up painting the Lazy Susan belly pan and wheel pant with the semi-gloss black paint I mistakenly bought. At least I put the paint to good use.

In order to check the tire pressure and fill the tire with air, I have to git lucky with the roll of the tire so the air valve is exposed at the 6 o'clock position or I have to take the back part of the right wheel pant off by cutting two zip ties.

Ready to git it all hooked up and go out fer a spin.

Put the tail cone back on...seems a little crooked.





Made the mud flap into a fixed rudder tail! I had to find a way of keeping it on there.




I shouldn't have any issues of impacting the curb when backing up since I have it mounted much higher this time around. I've even accounted fer the back end dropping when the wheel swivels around.

Pulled the rudder off and put on new reflective "1WD" lettering on the both sides of the tail cone.

Over 24' of belly pan!




Rear view from above...

Hi,

Do you have any data to show how each modification has impacted your fuel usage?

It woudl be interesting to see which ones had the biggest impact and which ones had unexpected impacts, for example, you thought it would make a big difference, but only made a small difference, or the other way around.

As speeds build up, aerodymanics can be a tricky thing.

Oliver.

All I can offer up is my fuel logs and some notes of each year.

2009 1998 Toyota T-100 ext cab - 3.4L/auto SR5 Gas Mileage (BZP T-100 (2009)) - EcoModder.com
2010 1998 Toyota T-100 ext cab - 3.4L/auto SR5 Gas Mileage (BZP T-100 (2010)) - EcoModder.com
2011 1998 Toyota T-100 ext cab - 3.4L/auto SR5 Gas Mileage (BZP T-100 (2011)) - EcoModder.com
2012 1998 Toyota T-100 ext cab - 3.4L/auto SR5 Gas Mileage (BZP T-100 (2012)) - EcoModder.com
2013 1998 Toyota T-100 SR5 Gas Mileage (BZP T-100 (2013)) - EcoModder.com
2014 1998 Toyota T-100 SR5 Gas Mileage (BZP T-100 (2014)) - EcoModder.com
2015 1998 Toyota T-100 SR5 Gas Mileage (BZP T-100 current (2015)) - EcoModder.com

Since each mod was developed in a rough form and then later refined as other mods were being introduced, I don't know if I could separate the data on any particular mod based on it's success or failure. Some mods didn't work out while others went on to be developed further as my skills improved. A good example is the trailer as I keep changing a few things to see how far I can take it. Who knows...I might tear it back down again and rebuild it as I develop better skill sets.

Added in a skid/wing plate to the bottom of the tail cone.




Got an indicated 27.3mpg at 65mph fer a run from Navasota to Hearne (best ever fer this run) and an overall of an indicated 26.6mpg at 65mph back to College Station! Possible potential fer better aero? I guess it's becoming more like a motor boat!

I guess it's like the hydro stabilizer fin they have fer boats?
