Planning Aero Mods

[Doofus McFancypants]

Hey all -
Thanks for the thoughts.

Lazarus - my driving is mostly City - atlanta traffic in the 'burbs - mostly 35 zones.
there is one strech of 3 miles i get up to 55 ish.

Looking at the back - it does not look to bad.

I was looking at the car the other day - I know there are some other threads about wheel size - I was thinking that smaller width wheels on the rear would allow wheel skirts to be easier to install. That and cleaning up some of the front areas would be good ( fog light area - upper grill area) i also started thinking about the under side. Next weekend going to take a closer look under the car.

I am off for Vacation ( week in Pennsylvania - taking the kids Tubing in the Pocconos ( Cammelback for the PA folks here)

I will catch you guys later.

Drive smart - and safe.

Steve

With those kinds of speeds aero is not going to help a whole lot. LLR tires, Belly pan, grill block, block heater, higher t-stat and route survey to find the best route would be a good start. Keep us posted.

Edit: Some kind of instrumentation (Scan gauge, super MID)

I agree with Lazarus. Your not spending much time at high speeds, and your probably accelerating a lot. To add to his list I would look into weight reduction.

I live in the ATL suburbs as well and most of my driving is between 35mph and 60mph. So far I have gotten the solid "moon disk" wheel caps (more for looks, but might help a little bit on the highway, but no tests yet) and I have planned mods to do wheel skirts, read VGs and grill blocks before I head down to Disney World around mid March for spring break.

I would have to agree with Lazarus though, most of my gains in mpg were from changing driving habits. A lot of the driving in the area that you and I live in is stop and go, however, so I have noticed substantial gains in mpg from putting a limit on how much acceleration from a light I give myself, getting into neutral whenever I have a hill to coast down (and in GA there seem to be many of those). I also, recently, have started turning off the car at lights and often while coasting (EOC) instead of just neutral and I should have the test data for that in the next week or two, whenever I need to fill up again.

If you take a look at the millage on my Camry, I went from 22mpg to 28mpg this last tank just by coasting more and limiting my acceleration from lights. I expect to see between 30 - 35mpg after I start to EOC more.

I have to reply here just because someone said Logan's Run!!

Sorry to kick up the thread again but I an Altima Driver myself and seem to syuck in the 31-33 mpg area. I think the only gains I can make now are aero mods.

I was reviewing this thread and looking at:

-Lowering
-Wheel skirts
-Grilleblock (there sure are lotsa' openings up there)
-Mirror delete (it may be the pic, but they look huge)
-Airdam or bellypan

Does anyone have any recommendations on brands for lowering springs/shocks? I am also going to be removing the bumper and putting in the grill blocks? Based on the car above would you recommend filling in all areas? I was thinking the fog holes and top grille for sure, just not sure about the lower hole.



I also need to see if it is legal to do the mirror delete. Any and all advice is appreciated.

I would block off and smooth out the whole lower bumper, but only
if the bottom half of the upper intake was lined up well with the radiator.

(A lot of the upper intake on my CRV was higher than the radiator).

Then, I would hook up an SG2 see if the upper intake would do the job..
If it was okay, I would then put a smooth block across the top half of the upper intake. Take that notch out of the hood's leading edge. Make it smooth.

Can someone photo shop that? The only intake would be the lower half of the upper grill.

Quick and dirty gimping:

Dang! That looks good! The bumper looks almost like an air dam and the hood
looks slick too. My guess is that intake will do the job nicely.
