How's your MPG?

My wagon is 37.28mpg in town and on highway 44.74mpg ​

 

Holding Strong at 12 City.

 

19 MPG on the street
Avg. 23 on the freeway with 3.73 gears :2_thumbs_up_-_anima

 

That's a Canuck gallon, eh?

 

Nope YANKEE gallons

Before the 3.73s I regularly got 25 on the freeway and knocked down two tanks at 27+
These TBI cars only have 180 hp and an AOD trans, they get good gas mileage!

BTW... I used to have a Fairmont Wagon, I loved that car, I put 181,000 miles on that thing and all I ever did was regular wear and tear stuff (and tighten the carb every so often). When I was done with it I gave it away and all it needed was a new steering rack.

 

Impressive! HandyAndy just sent me a link on a TBI retro on a Bronco Inline 6. Good stuff.

 

Cool, there are lots of good sites for GM TBI retro fitting, The system was installed on MILLIONS of cars and trucks.

 

I'd love to do a TBI conversion on my wagon but California frowns on those type of mods.

However, My 85 Cougar I had with the 3.8 V6 got a consistant 28 on the highway with the TBI which Ford called CFI.

 

Well now we know what to look for, Andy's got a throttle body (Holley). 28 MPG on a V6 in a heavier car, on a US gallon. The mind swirls with possibilities.

 

The actual most difficult part of any FI mod is the fuel tank. You cannot run the proper pressures without the fuel pump inside the tank. In the case of the Fox wagons you have to get all the stuff from a FOX LTD wagon that was equipped with CFI including the tank and all the fuel lines. The tank is easy. Replacements are available new from Auto Zone and other parts stores. I would imagine the fuel lines would be a little more difficult.

 

Now you're tempting me. You know me enough to take on a challenge.

Sounds like a happy compromise between getting a Hi-Perf Mustang I4 or modding the I6. I wonder if the compression (Heads/Cam, etc.) would need to change.

 

This was all part of the original plan to transplant the 86 Tbird running gear into the wagon. One of the things I had to deal with was the fuel lines and the fact that the bird's wheel base is 104" vice the wagon of 105.5". I'm not sure how to get past that problem or whether the fuel lines would stretch that far. I was going to use the tbird tank but without major modification to the rear of the wagon that idea was out. But buying a replacement tank for the LTD wagon would be a bolt in. Less than $100. Still the fuel lines come up short as they attached to a top of the tank float/pump assy vice the front of the tank as the non-fuel injection wagons are equipped so that creates another shortage so to speak. If I remember right the fuel pressure is 39-42 psi on the CFI versions vice 4-7 on the carb versions. All the fuel lines have to be replaced.

I'd really like to install a fuel injected engine but more thinking is in order before a swap of this kind can be made. Not to mention a new engine or rebuild the current one.

 

I saw 2 Mustangs at the J/Y. A 1984 with the 145 HP I4 and a 1989 with a 190 HP I4, both with Turbo. One Auto, one 4 speed std.

I'd rebuild either one to stock condition. The 302 V8 was punchy with 140 HP, but the I4 engines wind up much faster. The 190 HP might be too tempting to step on it, at today's ticket prices!

 

The bad part Norm is the I4 needs the V8 K member.

 

The good part is that I kept it!
