Seeing as some of you think its a joke or stupid.. I've set a goal. I can already squeeze out 30 mpg by changing driving technique and turning the ALDA in( I can still beat a school bus off the line)

Here are the plans

- mirror delete ( passenger side done, might just leave it that way)
- smooth wheel covers ( undergoing design and then testing)
- rear spoiler, thinking W123 AMG spoiler
- rear wheel skirts ( removable and no mods to the body work)
- front air dam to divert air
- partial grill block ( reason to wire the AUX fan so it can be used to aid in cooling while stopped)
- some form of mechanical based mpg computer seeing as we don't have obdII ports
-front skid plate ( I still know of a few for sale.. factory of course, maybe mod it to it extends to the back)
- telemetry... analog of course, gotta keep it real. EGT's, coolant( digital monitor instead of the guage cluster), boost, and something else.. voltage maybe.
- lower it ( wish I didn't sell my vogtlands now.... )

I need to get a frontal area shot done so I can calculate frontal area and do some tests to determine the .cd of the car ( isn't there factory specs on that somewhere or is that the w126)


What I will not be doing is stripping the interior, I've already removed and reinstalled it 10 times, cut into the body(except to repair the rust spot I have), do anything that compromises the safety of my, my passengers or te general public and the most important of all. I don't care how many mpg's removing the hood star will save, it stays!


why am I doing this? Because, it's my car, I can do as I please as long as its safe. To give other members insight and maybe ideas, to save fuel since I think green, a lot. Also because it interests me and is something I would like to do with my degree in engineering whenever I get it. See, that is my goal in life, to design and engineer things that are green and go above and beyond.



so, say what you want, do what you want, but it's my car and I have the last say.

Let the project begin...

Code name " Aero Brick"

There is no way you are going to get a 35% gain in efficiency without some major bodywork and getting rid of the 617 for a 616.

Fixed that for you

I fixed your fix.

I was watching CNN and this hypermiler was actually turning his car off while coasting off the highway. He was also pushing his car out of the driveway and gives the car a running start before he fires up the engine. I suppose if you had a manual transmission and some muscles...

That only shows he doesn't know how his car works. When a fuel injected car is coasting on the highway in gear it is not consuming any fuel since the computer stops the injections.

Some people get a little nuts, fuel ain't that expensive.

I spent more on booze last night than I spent on fuel last month.

I've thought about how to do this. It's a little complicated in that you need to measure the difference between the fuel delivered to the IP and the fuel returned through the return line.

Not impossible, just complicated.

FloScan makes a diesel flow meter for marine use. I suspect it somehow measures the flow to and from the engine then subtracts the return and displays the difference.

It probably displays in gal/hr too.

That's an interesting looking 5-speed in the AMG ad....FWIW, the biggest single improvement you can make to improve mileage in one of these cars is to install an 5-speed with an overdrive top gear. I went from 23 to 26-27 mpg in mine after installing the 5-speed and I haven't changed my driving style one iota.

Even with 2.88 gears it's a simple fact that they turn too damned fast at highway speed.

If I consider that I have about $750.00 in the 5-speed conversion, at 4 $4.79/gallon it will take approximately 27250 miles to recover the cost. Of course, if fuel continues to go up, the amortization is faster. I didn't take into consideration anything such as reduced engine wear, etc..

yea, very. But it has been done before.


ok.. maybe not 40mpg... I'll settle for 35

Lance, you're going for power. I'm going for efficiency/mpg's.

I'm not going for power, I'm going for drivability and mechanical efficiency.

If I wanted power I'd have the GT3576V turbo and a Myna pump on there right now.

I'm with you all the way, I have done the 2:47 swap and have gained about 20% on the highway. I to am looking for the high mpg out of my 123.
I'll keep you posted on a couple of other things on my up coming trip to Cincinati.

ok then.. I'm just working with what I've got.
