85.03 Crown Vic Coupe "CVGT"

[86VickyLX]

Needs lowering springs for stock ride height. LOL So much for your car stopping better than mine. They probably need to be bled again. Double triple quadruple check that you have no leaks, even the smallest amount of air will cause a non working pedal.

Also, on another side note. The box pump does not like the rack and pinion. It barely has any assist when still. So I think a smaller pulley will be in order for the future. I'll triple check the fluid again. It wasn't full manual steering, it was just barely any assist.

Might try a PS pump meant for a Mark VII. Those had a rack and peanut and they're physically identical. I can dig up the pressure and flow specs for a panther vs the mark vii later. Its in the shop manuals. If someone could dig up the same specs for an 03+ car, that would be helpful.

I'll check when I get home and see if my EVTM/shop DVD has that info.

Looks like the rack needs about 100 PSI more than the older pumps make.

1986 CV/GM, non-police
min flow: 6.1 L/min
min relief pressure: 1100 psi
max relief pressure: 1380 psi
max free flow @ 1500 rpm: 11.4 L/min

1986 CV/GM police and Lincoln Town Car
min flow: 6.1 L/min
min relief pressure: 1100 psi
max relief pressure: 1380 psi
max free flow @ 1500 rpm: 12.9 L/min

Proof that Lincolns are superior. We got cop pumps.

1991 Lincoln Mark VII Bill Blass
min flow: 6.1 L/min
min relief pressure: 1300 psi
max relief pressure: 1480 psi
max free flow @ 1500 rpm: 9.8 L/min

1991 Lincoln Mark VII LSC

min relief pressure: 1300 psi
max relief pressure: 1480 psi
max free flow @ 1500 rpm: 11.4 L/min

So an LSC pump would be better but not ideal?

[gadget73]

Seems that way. Pressure is about right, flow is low though. Not sure if other applications move more juice or not. That might just be the practical limits of that pump design. Not impossible that other pumps bolt up though. The ghost of hydroboost past might know.

[jaywish]

What is even better is the coyote has no mounting brackets for a hydraulic pump.

[Mr Bean]

What about a SN95 Mustang pump? They had rack and pinion.

Ford Aerostar pump seems to be the proper specs and such.

I'm glad everyone chimed in about the pump situation. I think Johns right about the Aerostar one, so I'll probably look into this when I recoop some funds..

Well I drove it again today, just for laughs. It's got some good giddy up and go, I really really hate the hydraulic clutch setup. I can't get this stupid slave cylinder to push forward far enough. It's basically just pushing it forward enough to barely disengage the clutch and at the same, riding the clutch. So. Fuck. Hydraulic. Clutches. Until I figure out how to fix the problem. Brakes still don't work. My buddy is coming over to help with that. It's got mufflers on it and a horrendous header leak, which will need to be attended to. Uh... I bolted in the passenger seat.

[Brown_Muscle]

Perhaps the pushrod of the slave isn't positioned correctly with the pedal? Something isn't right there, I've had decent pedal feel with hydraulic setups

That's what I checked last night, when I put the retainer clip on the brake pedal shaft. But it's on there right. I guess i'll just bleed the brakes again. I never bled the master cylinder, so maybe that's the cause.
