Fuel pressure and A/F ratio would be big data items. The A/F ratio I want to see prominently if possible, such as below the main cluster, or on the A pillar. The boost level should be a less important daily item, the others I think of as warning information more than the boost. You need them all while setting it all up, tuning it etc.

My goal with this gauge is to have as much of an OEM (like Ford did this from the factory in 2000) look as possible.

The new gauge will end up matching all of the other factory displays in the truck ( Limited Center Console, upper ceiling console, auto HVAC and factory radio)

I chose boost and fuel pressure as I found during my research that the factory and saleen most consistently used those two gauges in their past supercharged applications.
 






For me intake temp is important
And
Air fuel
She don't even look at the boost
 






I agree I lean to an OEM appearance or feel for everything. But I also go to the best things, information in this case, I want the most important things easy to find and see.

That display used for boost and fuel pressure will be very good and useful. For an application that is mild in its power enhancement, that will be good. If it was a 15psi boost level, I'd push hard to say the A/F ratio is critical to see constantly, and the IAT's also if they could possibly be an issue. Using meth/H2O injection makes IAT's constantly critical, with a large intercooler the IAT's should be manageable without too much worry.

I think with 6psi of boost, once you get it tuned right, then the fuel pressure and A/F should be the main and minor needs. Those are related of course, so the fuel pressure would be the one to worry about a weak fuel pump etc.

Yes the test function on my meth system is nice
 






Thanks for the input everyone. The good thing about this new gauge is that you can hook up a huge number of sensors to it either at the beginning or at a later stage so if I end up turning up the boost at some point in the future - I'll have those options.

This screen is a 2 line by 16 character display which I sized this way in order to fit into the area that I am placing it as seen on the mockup. Another option is a 4 X 20 character display as well.

My factory head unit is a 2 Din touchscreen Kenwood Excelon which has a feature where I can display multiple graphical gauge outputs as well. If I end up going with additional gauges other than my boost and fuel pressure - I'll probably use that in the future.
 






Ford Motorsport SVO Powerdyne Supercharger Installation - Part 3… plus found Saleen XP8 Ford Explorer Borla Exhaust which is now on its way here!

So the first thing I’m pretty happy about is I was able to find an original Saleen XP8 Ford Explorer Borla exhaust system (from 00-0023 - the same truck where my Saleen Hood and Wing came from) and it’s now on its way here. I’m thinking we should be able to give this cat back system a good bead blasting and it will clean up quite well. I’ve been undecided on exactly what I have wanted to do as far as exhaust so I’m going to try this system out for the time being and see how it works. These pictures are from when it was shipped to me and it should arrive and be installed prior to my truck going to the tuner.

Now to the supercharger install update. The Motorcraft Mustang GT500 injectors have been installed. The fuel rails had to be lowered in order to fit the new lower profile injectors. This has been completed.

Picked up a new harmonic balancer and we had some machining done so the drive pulley spacer so fits correctly. If you recall from one of my previous posts the powerdyne supplied balancer was not included with my kit and my stock balancer was shot so I had to order a new one and have it modified in order to fit the spacer. I’m assuming from old EF posting this is similar to what Powerdyne did with their kit for the Explorer.

We had a little trouble with one bolt holding the old alternator bracket but with a little heating and encouragement finally managed to convince it to come out without any issues.

Now prepping the upper intake for some paint so it looks nicer for install once the TrickFlow spacer is installed.

Fun stuff! :chug:

It took my a ton of research to find the proper length exact fit Injectors

Ford Motorsport SVO Powerdyne Supercharger Installation - Part 4

Modifying the 86-93 Ford Mustang 75mm throttle body for the 5.0 explorer 2nd Generation Ford Explorer.

Going through some old posts on Explorer Forum we found some detailed instructions to modify the throttle mechanism to work with the Explorer. After beginning the process we determined that it was possible to transfer the linkage from the stock throttle body to the Mustang throttle body without too much effort. Just grinded off the stock mechanism, hit it with a punch and transferred it to rhe new throttle body. Kept the adjustment screw from the original throttle body. Now works perfectly!

So driver's side motor mount is completely shot and passenger's side not too good as well. No wonder the headers were banging against the brake booster. But seriously - all the stuff that has to come apart to change these out (doing transmission mount too)......

Oh well
 












Saleen XP8 Explorer Borla exhaust mock-up test

So checking to see how the tip of the Saleen XP8 Exhaust will look on Big White. Personally I did not want to go with the original polished look of the Saleen XP8 exhaust Borla tip as there is no chrome or shiny bits on the entire truck.

What does everyone think? Leave it this color or perhaps flat black or something different?

All opinions appreciated. Thanks in advance 🙏.

That fits very well, just the right amount showing. I would paint it all with either high heat paint or engine paint, which ever you find in a color you prefer.

The color is tough to choose, chrome or glossy silver or black, I'd like all of them to some extent.
 












Ford Motorsport SVO Powerdyne Supercharger installation - Part 5

So ordered a 2.80 pulley from 928 Motorsports to have on hand when Big White goes to the tuner. The Ford  Motorsport SVO Powerdyne Supercharger has a 3.0 pulley installed from the factory which I understand should support up to 6lbs of boost on a stock Explorer without all the upgrades that are on my truck. I’m not quite sure how much boost this new 2.80 pulley will support Dash I guess we will just see once it goes to the tuner. I tried to do the calculations but some things were not clear 100% plus Big White has headers, bigger injectors, bigger maf, TB, TB elbow, intake spacer and more - all of which I’m sure will be factor with the potential boost level with this new pulley.

Also finished restoring the Borla Exhaust from Saleen XP8 Ford Explorer 2000-0023. It is now installed on Big White with a new finish look.

The other huge thing completed was installation of the new motor mounts and transmission mount. This was a hellish job that hopefully will never have to be repeated. I was having a problem with one tube of the driver’s side header banging against the brake booster during aggressive driving and hard acceleration. This was caused by the motor shifting too much from failed motor mounts. This banging also caused one of the ARP header bolts to back out of the engine which in turn resulted in a leak of the back drivers cylinder exhaust port. I’m also expecting that any strange vibrations that might have been previously observed possibly will have been eliminated by replacing the mounts. Fingers crossed.
