this thread is my quest for mpg.

i am up to 24+ from a low if around 14.

[billfisher]

well friday was a waste. i harrased a couple of cars and only got 18mpg. gotta stay out of it to do any good.

i made a timing chain holding tool out of wood and have one cam done. other tomorrow. idles way better. i forgot how much idle quality i gave up changing the cam timing.

Bill, are you still running the 5.4?

[Pyrotech72]

I drove from Murfreesboro to Atlanta and filled up today. Looks like I topped 26 mpg this time. Previously I got 25 then 24. My return to Tennessee is planned for tomorrow.

[billfisher]

yes it is the 5.4 3-valve still. i think i can get 30 or better with it.

My 5.0 drinks the gas....It needs a good tune to get decent mileage...that and me to keep my foot out of it!

[Pyrotech72]

I filled up in Manchester on the way home, since regular was 3.81 at the Raceway there. Apparently the fuel stop in GA didn't get the tank all the way full because it looked more like 23 mpg returning. Then again, I did pump a little extra because of the price. So I think it's safe to say I averaged 25 for the round trip. I'll know more when I go back to the same pump I used before heading south.

well, the 2.73's are half way in. i have set pinion depth and bearing preload. all thats left is carrier bearing pre load and lash.

i went ahead and rebuilt the posi clutch packs. so no more one wheel peels for me. 200,000 miles is enough for them. they are paper thin.

[billfisher]

i still think i can break 9.0 seconds even with 2.73's.

the fact is the tune i am using is miserable to drive. i have to never get in it, and always think about the gas peddle.
2.73's will free me to enjoy driving it once more.
also a full quieter exhaust and the sway bar is going back in. might as well handle a little.

[billfisher]

well the gears are in and quiet. it turns 1500 at 55 mph. i have to get a driven speedo gear for 2.73. it has the factory speedo gearset for the 3.08's.

ill post gas mileage tomorrow. i am tuning it for regular running. so there will be more in it if i lean it again. the downside of leaning it so much is the heat. the temps are high side of normal with the A/C on in highway driving, but in the city it overheats with the a/c on. so the regular running tune will be much cooler.

[Pyrotech72]

I think it's safe to say Too Slow gets almost 25 mpg highway. Depending on my driving style locally, anywhere from 17-19. My first tank on Green Go got about 20 mpg with the engine light on. Not bad for a lead-foot like mine.
(PCM code P1407: EGR No Flow Detected, so I have carbon deposits to remove)

I get 22 highway with my car. Full bolt on 97 cobra with 4.10s.

[billfisher]

well it used 6.59 gallons today with a regular tune. it just show how much the tune counts. so i reflashed it with the best bas mileage tune and report tomorrow.

economy today: 24.279 mpg.

about the same as 3.90 gears and an extreme lean tune.

so now it has the 2.73's and an extreme lean tune. it runs about 1700 rpm at 64 mph.

SUCCESS !!!

IT USED 5.272 GALLONS TODAY !!!!!
which equals 30.349 mpg!!!!!!

i realized something was wrong yesterday. i just changes my rear brakes and the driver's side was dragging. that and dropping the fuel pressure to 35psi seemed to work.

now that 30+mpg is here i am continuing the trek. i am adding the cmc plates back anyway. it will cost me about 7hp/7tq. if it yields mpg its worth it. the taller tires for the rear are going on. i never got around to putting them on.

also i am putting th factory MAF back on tonight and tuning for it. i want to see if the factory sensor is better/more accurate for low speed driving.

woo hoo

[Guest]

congrats.. 30+mpg is nothing to be looked at lightly

Wouldn't it be easier to just go buy a used Focus?
