95 Mustang MS3 wont rev past 5xxx rpm

Unread postby beyondEOD » Thu Jun 25, 2020 10:48 am

Hello,

Can anyone offer any assistance with my setup.

1995 Mustang GT 5.0
GT40p Heads with 136/360# Springs
Anderson B31 Cam

Setup:
MS3 Gold Box
Microsquirt TCU on an AODE
I cannot get the car to rev past 5xxx rpm under load or free rev.

Pulled autolite 104 plugs and gapped to .042.

Checked timing with light when fixed at 20 degrees.
Stock TFI with a Reman Distributor that worked when ecu was stock.

Installed a used 94 OE distributor (looks pretty used). That gained me about 700 rpm. Previously with the reman it was limited to 4500 or so.


Checked TFI connector pin 4 for voltage with the key forward. None present. Not sure if this is the right was to test.

I'll upload logs and tune when I get home.

I do not see a suitable way to attach a ground wire directly to the distributor. What do you recommend?

there should be a threaded attachment screw on the housing

are you using an oem ford distributor?

Yes sir.

I swapped the rotor from the reman since it looked better than the oe.

Went out for a drive was able to get it to 5700 on one occasion while logging. Then I realized the car was running 230 degrees after and drove it home. It cooled off to 200 by the time I got back in the driveway. I figured the cooling system had air in it. I pulled the cap and let it sit while running and noticed lots of white foam. I thought this could be from the zerex flush liquid that I used.

I did a few drains and refills with water to see if it helped.
Here is after 2 full radiator drains.

Is this normal? Should I flush with water more?

....head gasket...???

cant rell much from a video

after a while the thermo should have opened and sucked some water down. The bubbling would have eventually stopped too. Might take 10 min or so.

sbf's very seldom have head gasket issues unless something is majorly wrong

It does suck the coolant down. I'm going to do a leak down just in case. I would not think I'd have issues as the heads were machined and I used all the right things.

I was reading through your reference articles again this morning looking at spark plug recommendations. I stumbled upon where you reference the TFI module as it should be a Gray module for 94 and 95 vehicles. I will check later today but I am almost positive mine has a black module. Outside of whatever I have going on potentially with a head gasket or cooling system could this black module be causing my Ignition related issues?

Should I have a different TFI. This one appears to be for a Ranger when I search it.

Alright today was productive.

Pulled valvecovers and upper intake.
Checked tq on head bolts and readjusted valvetrain.
Lower intake was pretty loose. I took them to 25ftlbs.
Performed leakdown on each cylinder. All good. No bubbles in coolant.
Regapped plugs back out to .054 since .040 made no difference.
Reinstalled everything.
New TFI should be here tomorrow to test with.

Forgot to mention previously I was able to hit the limiter at 6100 if I took it there slowly and didnt go WOT.

if the limit is a function of cylinder pressure then the ignition coil would be the likely culprit

Very good, I was thinking coil would be soon if the TFI did not change anything.

Looking at coils.
Motorcraft vs Delphi?? Delphi is half the cost, does it work half as good?

Ok update:

I retorqued all head bolts. Ran the Leak down and coolant pressure test. All good no bubbles in coolant.

Super flushed the entire system so it's straight water. Ran a coolant gas check. FAILED. Gasses are getting into the coolant track.

I'm going to remove the headd and see if the gasket is visibly damaged. If it looks fine I'm going to have the heads checked again at the machine shop.
