Progress Thread 74 Mustang II - Build as semi-daily driver

[Noobz347]

If that air damn can take curb, then I like it.


Probably the fastest mustang two in the world for this week.
Score an extra point.
Our Hero extra_stout!

It sits under the radiator support on my 86 so.... Don't park on the sidewalk.

Cut, shape, and fit something like this to the front of the car to help cut air beneath the car:

You know... I like to experiment, but I also like to be alive.

Ok... How does that apply?

Something about parking on the sidewalk?

 

[extra_stout]

On the 1gen Mustang race car drivers had problem with aerodynamics beginning at 140 MPH... in a way that the hood did act like a wing and the car did get light at the front wheels. I don't want to experience that.

I do not want to experiment with aerodynamics... or with parking on sidewalks.

My tacho conversion seems to work. A friend helped me with RPM reading with my ignition light and comparing it to the modified tacho... at night, because it is much easier at daylight.
I will post some pictures how I did the conversion. Its not more than 100 RPM off from idle up to 4000 RPM. That works for me.
- burn the whole fuel tank nearly empty to get new fuel into it before wheater is getting bad
- tacho conversion from 6 to 8 cylinders => 650 Ohm resistor
- installation of new used fuel level and water temp gauge (the old ones get stuck, the new used ones worked fine in a bench test)
- reverse light is not working; look up where the error is
- maintanance

Things I want to do, but will more likely a thing for next year (hopefully):
- remove DB killers from exhaust (measure before and after to see if it is nearly legal)
- install new u-joints on driveshaft (+ paint); check drive line angles
- custom adjustable front sway bar
- wheels?!

I just passed TÜV inspection without problems
So two years more driving with inner pease. I tought it could be time to cross of old points from my todo list and add new points:
- burn the whole fuel tank nearly empty to get new fuel into it before wheater is getting bad
- tacho conversion from 6 to 8 cylinders => 650 Ohm resistor
- installation of new used fuel level and water temp gauge (the old ones get stuck, the new used ones worked fine in a bench test)
- reverse light is not working; look up where the error is
- maintanance

- remove DB killers from exhaust (measure before and after to see if it is nearly legal)
- install new u-joints on driveshaft (+ paint);
- wheels?! update 2026: at home and modified to fit the car; need to get tires
- check drive line angles and check driveshaft slip yoke for play
- front springs installation
- rear spoiler installation / repaint hood scoop and rear spoiler in 2K epoxy paint (black)
- check wiring of lamda sensor
- install gauges (solution for oil temp and pressure sensor?!)
- custom adjustable front sway bar

Hopefully I have more time for the car in the next two years. Drove just little more than 1000 miles in the last two years...

A front air dam is hardly "experimenting"
Virtually ever car/truck ever made in the last 40+ years has a front air dam on it.
It is a proven way to keep air from getting under the vehicle, which helps stability and improves fuel efficiency.

Right on Extra Stout
I luv this update!

Seeing things checked off list is Good!
Passing Inspection = Most excellent
Still putting milage on that old Mustang feels nice.
Still might need a fresh picture...

"- tacho conversion from 6 to 8 cylinders => 650 Ohm resistor"

Where did you install this resistor?

The speedometer and tachometer have different readings on the V8; did you change both of them?

 

[LILCBRA]

Our speedometers are mechanically driven so there should be no need to install a resistor for it.

 

[extra_stout]

The resistor converted the V6 RPM gauge to work with the V8 ignition signal input.
The C4 speedometer cable worked fine with the T5 transmission, I just needed to to the math to chose the right tooth count for the speedometer gear.

@2Blue2 you will get fresh pictured at latest when I get new wheels installed...

Looks like the resistor goes in the red wire: https://stangnet.com/mustang-forums/threads/tachometer-conversion-from-6-to-8-cylinder-will-also-work-for-4-to-6-or-4-to-8-but-with-different-resistor-size.924607/#:~:text=The conversion works only from lower cylinder,shows with a V8 following RPM: RPMv6tacho=8/6*RPMreal.

Had issues with my battery... Finally I replaced it and optimized the bracket Holding IT down with some heatshilding.
Perhaps it helps. Lets See.

And!!! I Picked Up my new "old" car/nugget. Low mileage 2009...
Around 2000 lbs with 17x7 wheels. Everthing original except the Eibach 20mm lowering springs.

The Wifey is gonna love it.

The Wifey is gonna love it.

She does and me too. It's a light nugget. It has TI VCT (V-TEC) that kicks in at around 3500 to 4000 RPM. Its so funny. Did get a new cam drive belt cleaned the magnetic valves for the TI VCT cam, which they didn't need, whats a good sign. Played a little with tire pressure. It's a pocket rocket...
I saw that the ST version with turbo was also sold in the US and has a small fan base. Turbo would be nice, but we drive that only on short distance so it doesn't make sense for us as a daily. But I could by a total damage ST in some years and do a swap with all the running gear. But for now I'm really happy.

Back to Mustang: I had to re-adjust the carburator, because I put in more fuel and idle RPM, when the battery was dying, to get home. After adjustment the car ran great. Than i parked it for 1 or 2 weeks and after that I had popping exhaust from time to time and much lower power than before. Like running not on all cylinders.
I'm thinking if the issues are related to ignition. So I need to look that up next. I want to go trough to my setup with coil, pre-resistor and pertronix module. I should also check if alternator stopped working, which could also explain battery issues.
It never stops. But perhaps it's my past me hiding some easter eggs...
