Wheel Covers (Pizza Pans) DIY Fabrication :

Decided to put smooth wheel covers (pizza pan).
It was pretty simple, I bought some pizza pans and I nailed the cover on the original wheel cap. Took me 3 hours to make.

Here are some picture of the wheel covers :

The Wheel Cover :

Results Of the Wheel Covers (Pizza Pans) Tests! :

Today we have tested the wheel covers to prove their efficacity and their FE with an A-B-A test.

Here are the Results :
11C (51,8F) / Speed : 50 MPH (80 Km/H) / 06 October 2011 / Good Conditions in general.

A = With the Wheel Smooth Covers (Pizza Pans)
B = Without the Wheel Smooth Covers (Pizza Pans)

In MPG (US) :
Run # 1 |-61.2-|-59.5-|-62.4-|
Run # 2 |-57.2-|-57.1-|-57.6-|

Results :

Run # 1 Combined A = 61.8 MPG (US) (3.81 L/100Km)
Run # 1 Result of B = 59.5 MPG (US) (3.95 L/100Km)
Run # 2 Combined A = 57.4 MPG (US) (4.1 L/100Km)
Run # 2 Result of B = 57.1 MPG (US) (4.12 L/100Km)

Difference of 2.3 MPG (US) With the Run # 1.
Difference of 0.3 MPG (US) With the Run # 2

Final Result of the Testing of the Wheel Covers (Pizza Pans) :

We calculated a 2.15% gain in MPG (US) with the Wheel Covers. Yay!^^

Whiper Deflector in Coroplast DIY Fabrication :

Realized the wipers was really in the airflow so I decided to make a coroplast and duct tape whiper deflector to respect airflow near the wipers zone. It took me maybe 2 or 3 hours to build it. I made tests with the deflector but they are lost in the Void. We know that it is a 1.5% gain in MPG (US). Based on a A-B-A-B test. Inconveniant : some leaves and maple scrap get stuck in there.

Some Picture of the Wiper Deflector :

Partial Front Grill Block DIY Fabrication :

We are in Canada so winter is one of our preocupation. I decided to make a Grill Block to help Engine keep its heat. Its made out of Styrofoam and Duct Tape. Took me 1 hour to do and work well. Not tested. It is also blocking the hole for the fog lights (I don't have any).

Added upper grill block made of coroplast and duct tape.

Here are some Picture of the Grill Block :

Went in Ontario this morning with echo-francis to take some electoral coroplast... We got 19 small and 11 large.
What does that mean?
Wheel skirts! Maybe belly pan. We will have a heated place to work on the echo-troll this winter, so we will keep you in touch with those improvements.
