New with 04 Maxima
 

2 years ago i wanted to add underbody panels to inporve my areodynamics; to become quicker and better mpg. also, i added an aftermarket bumper that no longer allowed my stock "engine splash/aero shield" to fit. so i purchased 2 sheets of polycarbonate.

i had no idea on how to attach it, plus still have not finished the bumper since the lower grille never arrived :mad:

well with gas prices i want to finish this project. i found this site along with countless others. but it's awesome to find a forum where people are doing these projects and talking about them.

i posted my thread here http://ecomodder.com/forum/showthrea...help-3465.html

i plan to make a front air dam.
block my lower grille and fog light openings.
divert air entering the main grille to flow upwards (with coroplast).

later i may add diffusers to the rear. i see my gas tank is really low though, so i may just close the gap between it and the bumper cover.

i can get 30mpg cruising on the highway. i ave 20-22 since i do mostly city driving.

Nice looking car! With some work you might be able to get 30 combined, :)

Welcome to ecomodder!

That is one fine looking automobile!

Welcome to EM! When I look at the rear slope to your Maxima's roof, it looks closer to the "good aero" rule of "no more than 15 degrees" than other sedans.

Regarding the polycarbonate, I am going to assume it is as flexible as coroplast. A lot of people use cardboard to perfect a template and test the mod. I keep thinking you could use some strategic zip ties to attach it. The virtue would be easy-off if there is an overheat issue (not likely based on the upper grill). If the plastic does have to flex, the bumper *appears* to be a shallow-angled curve to me.

Welcome to EM...

Very nice Maxima. I can't tell from the pic -- is that custom paint?

I always enjoyed driving the Maxima SE (rentals). One of the best engines made, handles great for the size, etc.

Enjoy the site, and best FE to ya :thumbup:

thanks everyone!
that's just the stock nissan black paint. though my front end was repainted again recently. it's bitter-sweet to clean her. overall the up to 8 hours i spend detailing makes her look amazing, but i see all the battle scars from rock chips and door dings :(

i swear clean clayed, polished, and waxed paint is more aerodynamic. your hand will slip right off my paint, i imagine air glides more smoothly over it too.

combined 30mpg? that would be incredible. stock the car has a Cd of .28 but i don't know how my custom bumper changes it. once i block off the bottom, i would hope it improves it greatly since it is way lower in the front now.
