Aeromods on my GasHOG

[rav]

After learning a lot of tricks from you guys over the past year, i have been gradually modifying my 08 liberty aka GasHOG, here is the progress so far:

The obvious Fia grill block, warms up the truck a lot faster:



Honda ridgeline style diffusers on the mirror:


Added Front and rear tire air deflectors, I tried to put a bigger air dam up front, but after numerous failed attempts, I just put inverted mudflaps and happy as to how they turned out:



Side view:



Rear tire deflector, it looks a lot bigger than it actually is, but i may trim it a little more:



Rear kammback, ordered a 48"x 12" smoked plexiglass, It was a nightmare to bend with a heat gun. In hindsight, I should not have ordered the 1/4" one as it is too thick, but the rear of the liberty has these 1/4" ridges and i notched the plexiglass at either ends to fit it flush with the ridges so that it stays on the roof line. The clips are just there temporarily till the acrylic foam tape cures.


Its in line with the roof:



Side view:


Any comments and constructive criticism is always welcome

You're in the right direction. The plexiglass is probably not doing anything, nor are the little diffusers on the mirrors. The rest looks pretty good though.

Rav -

Really good. I like the front tire deflector. It looks like you are following the "classic" OEM look on other cars, covering part of the tire and part of the axle.

I am definitely interested in how the kammback works. I hadn't heard of using "acrylic foam tape" in other mods, so I am interested in it's long term durability. My paranoid brain assumes the kammback will "wiggle" and stress the tape over time.

Ha ha, you should wear one of those winter jackets that has the same stitch as the grill block. You and your Liberty would be in winter-wear.

While I agree with you on the diffusers for the mirror, I am not sure that i agree on the kammback, reading all the posts on here, almost everybody seems to have seen a slight increase. I am a little hopeful to see at least some gain. If not it will at least help my hatch stay clean.

As far as the acrylic foam tape is concerned it is commonly used to attach exterior moldings on cars or trucks. I had a rear air deflector on my older cherokee and i had used a single 1/2" tape and it held on great for 3+ years that i had the jeep. This one is attached by 3 1/2" tapes, we will see how long it lasts.

Just made a 20 mile run at 55 mph without the clips and the kammbacjk stayed on.

I did the same thing on my Aerostar a few years back, didn't record an improvement. I may have been too blunt with it. I think it's a very slight benefit if anything.

Did your's shape downwards?

In my pics it is hard to see but the kammback has ~15 deg curve downwards. I hope it will have a positive effect. I am planning to get a scangauge to have a better record of my mpg.
