Aerodynamic mods on the "Tank"
 

So since i've gotten the car i've been slowly improving my fuel economy but i want more

Deleting the rear piping after the stock muffler and putting a turndown saved 10 pounds :D

So now it's only 4490 instead of 4500 pounds
but i still have horrible aerodynamics so i need a few ideas to help this

I'm already planning on lowering my El Camino and putting a tonneau cover on it so those are automatic mods. Sorry i'm not doing flat wheel covers I would put skirts if i could find them for my year el camino though.

Anyone have any more suggestions?

I want to do a flat underbelly but don't know how that would work with this car

Why the exhaust mod? Cutting the piping and letting the exhaust out earlier could allow more fumes into the cabin, killing you with carbon monoxide.

For serious weight reduction, give it EcoTec power. You'll even gain an OBD-II port for your ScanGauge.

For that matter, give it VTEC.

I've actually got a spare EcoTec motor that needs a timing chain and a head gasket...

I doubt you will find a manufactured skirt fer the El Camino. Yer better off fabbing something on yer own. ;)

How much effort/money/time you looking to put into this as a project? Simple things could be just grill block. Start out basic and work from there...unless yer paying someone else to do it fer you... ;)

You know i've actually seen a few 64-65 Elco's with shirts so i figure SOMEONE does it

and if you look in the garage you'll see i'm planning on spening ALOT on this car it's my first car so i'm keeping it forever

my plans are a 800 HP duramax that gets over 30 MPG freeway.. should be fairly easy with this car

Be careful you don't over-oil your K&N.

Regarding aero, take a piece of rope that can be easily seen, tie it to your front bumper, up and over the highest point of your cab, and down to your back bumper over the tailgate, then snap a digi of it.

Upload the pic here, then check the angle of the string in the pic compared to the ground. I'm fairly certain your cab/tailgate angle will be sufficient to just add a frame and some sheets of coroplast for an aero-cap without too much thought invested. Might be good for a decent gain. :thumbup:

(Try to test it somewhat scientifically, though...)

Dumped it at the rear axle i didn't just cut it and leave it open at the muffler, It's a turndown so really the only time it'd be dangerous is if i commuted and sat in traffic alot.. which i don't , but i know what you're talking about that's how it was when i had straight pipes

Is it a V6 ECOtech? I'd actually consider that

Oh i know better than that that's the only way i've seen them be harmful

Yeah I'll try that
I had a flush mounted campershell on it but i prefer the look without it
