BudW:
I did the swap (a bit of test'n'tune actually) using the extra washers and it worked absolutely fantastic on my setup, bulk of the over-power in the PS was gone.

I am now moving on to the new Borgenson chuck though, so some of that test'n'tune may have to be re-done actually...

Another update...

Power steering is all back together and I'm pleased with the results. Steering feel one the road is nice and firm and with low speed turning I'm no longer getting the jerking feeling from the wheel. It is hard though from a complete stop, almost feels like manual steering. I've got an idea to fix this.

So what I did was I replaced the flow reducer in the pump with one that is rated at 1.8 GPH. At the same time I removed the shims I had in the pressure valve to start at an easy baseline with the intent of adding shims afterwards if necessary. Turns out I don't need any. I want to preserve how I have it dialed in now for driving at speed, but somehow increase assist when I'm at a stop (or when the motor is at low RPM). Seeing as how the valves limit maximum flow and pressure and I have that dialed in, I don't want to screw with it anymore. To increase assist at low RPM I'm going to try and find a smaller pulley. The one I currently have is 6 7/8" in diameter.

The new pressure line I made up out of braided PTFE hose came out great - it sealed right up. It is actually easier to put the fittings on than traditional braided rubber too.

More to come...

Glad to hear you found the right "mix"...steering is so important to the overall feel of the car that it's nice to have it "just right".

Heck, as you know, you and your dad's +ve feedback prompted me to go down the path of Borgeson PS chuck...so at least here I'm crossing my fingers for the time being and hoping for the right feel once it's all together.

Got some me more toys from Summit. Finally decided to install electric dumps and I picked up the Holley distributor to enable timing control. Not pictured is a Bluetooth stereo deck I already installed last night. Time is kinda tight right now. Should be able to get the rest done this weekend.

Those are electric fuel pumps?

They look more like electric exhaust dumps (or something else . . .)

3" QTP electric dumps. Taking the car to a shop tomorrow to see about getting them installed.

Do tell more about the Holley distributor...is the ignition curve fully adjustable here, sort of along the lines of a FI fuel curve?

If so (I don't know the part numbers, and haven't looked this up yet - probalby will...) who drives the tach, will this beast hook up to the standard MP ECU?

It compliments the Holley Sniper EFI. The ECU will do timing control, but it needs a distributor that uses hall effect sensors; which this is. I've got a handheld in the car that I can tune it from. Right now the car doesn't have any advance at cruise and I'm looking forward to putting it in. Should increase mileage and cool the motor down. Andy over at Moparts swears by this setup. The tach is driven off of the ECU.

Thinking of trading in that prehistoric TQ for fuel injection? :p

If your going FI in a mild street build it's the way to go. It works the way a factory EFI does at that point.

I'm going to use the MSD box with programmable timing in the Ford and see if I like it. You lock the distributor and make your curves on the computer. Both my cars are traction challenged so pulling timing at the hit should help. We shall see.

Not gonna happen (it probably should, hard to deny the advantages of FI) the 2ndary openning sound is just too damned addictive! LOL

Well, it does have a whistle that starts at part throttle and runs all the way to WOT. Pretty damn loud too. Some guys on the Holley forum don't like it and have eliminated it by using a four hole gasket. Honestly, I think it sounds awesome. Might get annoying though if cruise in my car required enough throttle to get to that point, but it doesn't.

So we got the noise. What else? :p

Come to the dark side, we have real time fuel metering. :D

Be sure to post a thread on your findings. My Dad's car is still running a carb (has no interest in switching) and is traction challenged. That sounds like a pretty good option.

I've read some of more feature rich controllers like the MS3 can do traction control utilizing ABS sensors and pull timing out if it detects tire spin. Really wild stuff.

This one is going to be heavy on photos!

Another thing on the list to do was to reclaim the trunk. I don't need a stereo that rattles pieces off of the car anymore (I'm getting old), but I still wanted something decent. I came up with the idea of moving the sub up onto the shelf under the package tray. Not a lot of room, so I had to have a custom box made.

Below is the sub box. It's a 12" sub with a ported box. Took up damn near the entire trunk. It was huge.

To get an idea of how large it was vs the new box.

That bracket in the center which I can only guess is there to help support the spare tire is going to work great for this. The spare tire mount itself needed to come out though as it interfered with the box placement. A donut spare wasn't going to do anything for me anymore as it is way too small in diameter.

Hard to see in this photo, but I had to remove a metric ton of seam sealer the factory splooged to hide the welds. I chiseled off what I could and a wire wheel finished the rest. Made one hell of a mess!

Angle grinder for the win.

New box will rest on top of this bracket and be secured with screws from underneath. I may change this up later on and install studs in the box that can drop into place. This method is a complete pain in the neck. More than a few neighbors walked by while nothing but my legs could be seen sticking out of the trunk. Must have been a funny sight.

I really need new trunk carpet. Despite having to cut a section out it has plenty of rips and hole worn into it.
20190630_194105.jpg


The finished work. I reused the same sub and amp. It doesn't hit as hard due to it being a sealed box now, but I knew this going in. It still delivers more than enough low end.

Now onto the electric cutouts and Holley distributor!

Great progress and build.
Like the way you combine efi with a hall distributor. Using also lambda sensor? Would great if you could show a vid of tuning the ecu. No plans to go to MS3 combined with ABS with your disc setup ? ;)

The tuning through the handheld is pretty basic due to the limitations of a 4" screen. There is an accompanying piece of software for PC that allows you to open the saved tunes from the ECU though and really tune things. Here is a photo of the spark map I was working on:

You can alter the maps for fuel and other things as well. Sky is the limit really.

I had to pull it out though and go back to the MSD Pro Billet for the time being though. I couldn't get the clock right on the Holley dizzy without it hitting the head. What I need to do is pull the intake and re-clock the distributor drive gear. Was too close to a cruise to Woodward to continue messing with it.

Then this happened during the cruise:

Fire ring disintegrated on the head gasket and beat the piss out of the bottom of the head. I already got it all back together. All the damage to the head was inside the chamber and didn't affect any of the sealing surface. End up running a stone over and got it to smooth out.

I swear this hobby is a love, hate relationship.

Thanks for sharing the info about the ECU ignition timing.

Agree with the love hate relationship on this hobby. Hope you get the re-clock of the distributor with some more easily next time.
Possibility to read the output signal (voltage) of the hall sensor (VR) and check with the position of the crankshaft? I am not experience with holley, but with the Megajolt I had need a offset between Piston #1 TDC and hall sensor is kind of 60 degree (CCW). Kind of the most possibility advance ignition timing.
