New Guy w/ an 84 Mustang GT

Another fox body...welcome.

Good to see some four eyed pride around here, welcome! I know you have a 1984 but just to clarify 1986 was the first year for speed density FI, it was also the first year for factory 8.8 diff. and the World Class T5. And the first year for the third brakelight, so if you are spotting old Mustangs and see one with 4 headlights and 3 brakelights, it's an '86 lol. If I can recommend one thing that you will actually be able to feel a difference when driving and that will also help with your FE, it's an aluminum driveshaft. The factory ones are big heavy lumps, and reducing that much rotational mass is something that you can notice. Finding used parts for these cars is another plus to modding one, they have been so scienced out by the performance community over the years, and so many people have built them up that there are a TON of used parts floating around for them out there.

Get your self a wide band O2 gauge and carb tuning set.
Up to $250 for the gauge and $40 to $100 for a rod and jet set would be much cheaper than going EFI and would deliver much of the same MPGs.
Plus with older/cheaper EFI you cant lean burn, older EFI tries to stay as close to possible to 14.7:1. With a carb tuning kit and O2 gauge, depending on conditions you can get it to do what ever you want.

so hows ur pony working out?

ALso, increase the psi in the tires....maybe to 40psi for starter.
ANd you gotta get a gauge....Scangauge II

the 9 inch is considerably heavier and way over kill. if you decide to put a 8.8 in make sure its a 31 spline other wise ther isnt gonna be a big difference in strength to justify the weight cause the 7.5 and 28 spline 8.8 use the same axels. secondly a 7.5 can handle some serouse power i had one behind a turboed 2.3 in a ranger that put down 467hp at the wheels and was never babied oly reason i went with an 8.8 was got a good deal on it

Still no real update. I have had it running and on the road. I have to re-run my fuel lines to clear exhaust. Hope to put some real miles on it soon.

good luck.
glad to have you!

1.Centerforce or similar style clutch. reduce slippage increase mpg...
2.& 3. elec. fans and waterpump.
4. If you can live with the rack n pinion alone remove hydraulic pump.
5. side mirror deletes
5. 6. 7. Front spoiler and or air dam, lets just say ground effects kit.
8. If you can find it get a SVO biwing it compliments the aero, and does provide some down force.
9. SVO wheels were also nice for aerodynamics but your running 4 bolts not 5.
there was a GT wheel that looked like SVO wheel also mabe that works for ya.
FYI. upgrade to 5 lugs isnt bad job and not very expensive. the rear disks feel nice too.
10. forgot underdrive pulley.
Also with some exceptions 88% of power adders increase engine efficiency, and make wasting gas seem more fun too.

I wouldn't suggest added downforce. But spliiter/dam would pretty effective and cheap.
