So today i installed some new gauges. I added in cab fuel pressure, and Exhaust Backpressure. I got the dash/instrument cluster bezel, and put the fuel pressure and trans temp from the pillar onto the dash. Then moved EGT down to the bottom of the pillar, EBP in the center, and the compressor boost at the top. I have Autometer Sport comps, the ring on the bezel is silver, and since they dont make fuel or 0-60 boost in that series, went with Autometer Z series, which are basically the same but a black bezel ring. Doesnt bother me, and heck i might paint the rings on the 3 sport comps black as well. I finally got my trans temp gauge to work, after 17 months i finally got it working. I didn't think so, but i had to splice a wire for the sender. Didnt know the connection at the splice didn't pierce the insulation so it was an open circuit. Went to town for a half tank of fuel and it got up to 135ish.

Test drive- The EBP gauge flutters from 0-3 under light acceleration out of the driveway. pressure goes to 3-4psi before the boost needle moves off the peg at 2psi. with my 1.15 housing, at 10psi boost i have 14psi Drive pressure (DP). At 15psi, it registered 19psi DP, and with a full throttle run on 120race, i had 27psi of boost (boost is back!) and 42psi DP. For the EBP sender i had a compression fitting with a T at the top of the EBP line from the manifold. I took the sensor off the tube and the new sensor was clogged, i spent a half hour with weedeater .095 line cleaning the tube. I think i got some power back with that cleaning, im not sure if it was just a mental thing. Oh, fuel pressure is 70psi at idle, i have it boost referenced off of my fuel press regulator, and it raises the fuel pressure 1psi for every pound of boost. Don't have a fuel delivery problem, as 10psi boost was 78-80psi, and WOT was down pas 95psi fuel pressure. That's hard on the pump, i may set the pressure back to 62-65 so it doesnt overtask the pump, i have the pressure when i need it most, right.

Enough of the ernesting, here are some pics of the install.

 

LOL. I find his writings, well, um, interesting. I went to school for 20 years and can't quite follow some of his stuff, but he seems like he went to Engineering school...

Nice writeup though, Kris. Gauges look good.

 

Nice, the only thing i didnt like with that bezel is on my truck it covers up the WTS light, so instead of me using that light, i use my fuel pressure and when the pump shuts off i start the truck. Since I only have one gauge hole filled in mine, i can still see through the other one. Did u get that 2 way tape it came with to work? On mine it wouldnt work and i ended up using 3M outdoor 2 way tape and it worked much better.

 

Used a combination of that supplied tape, and super glue. If i had thought i would have used duct tape.

 

That's because he was/is an engineer. Those posts can be hard to follow at times but I generally know what he is talking about. The big problem for me is his math. I was never a math stud and I have to brush up on that when he posts like his last air flow post. Unfortunately, theory is just that. Principals and laws are for a lab and the PSD is not a lab. So with all of the variables in the PSD the laws/principals break down because we cannot control or properly measure what is going on at all times.

I'm still looking at his last post, and after cutting a hole in my skid plate tonight, and several brews, I doubt I'm going to make much headway.

I for one appreciate his efforts and am looking forward to his results of boost measured at the turbo outlet VS those at the MAP. I guess I didn't prod him hard enough. Heck, I may do it myself as I have a 4 gauge carb synch set from years ago when I had a bike. I may just test this myself someday.

Sorry, BTW, glad to see the boost is back Chris. Are you getting good smoke again with that added fuel?

 

Kris, where did you find that pesky boost leak?

 

Didnt search for, or find an exhaust nor boost leak. I however removed my severely clogged EBP tube and sensor, cleaned it and just today i can feel a def. added kick in the pants acceleration. However i will soon not have to worry about exhaust leaks.

 

Nice work Kris. An EBP gauge is something I've wanted to add. At least I know what my drive pressures are from your data though!

I too noticed what felt like an increase in power when I cleaned my tube and replaced my bad sensor. That alone tells me that the EBP sensor does play a role in how much fuel is being delivered. Perhaps it was that sensor tube being clogged that caused you to lose boost.

I would turn the fuel pressure down at idle to abotu 62 psi. You're right, it will be easier on the pump when it's running the most - at low boost situations. That's exactly why I boost referenced my fuel pressure last year. Easier on the pump at light throttle, but still have plenty of psi when the boost hits.

Not worry about exhaust leaks? Ceramic coated up-pipes on the way?

 

Getting the bellows, or something better yet?

 

yes, something better yet.

 

New turbo too? Complete TN kit? You didn't go compounds yet did you?

 

No i didn't do compounds. That would be sweet. I think i would need more fuel first, compounds on stock injectors? Could the secondary charger spool?

 

Good point. In my post Cinco celebration state of mind, that is something I forgot about.
Stock sticks probably wouldn't spool a second charger very well. Maybe the towing twins, but probably not the hot street.

So what exactly did you end up ordering?

 

Technically i havent ordered anything yet.

 

Will you quit dodging the question and just say what you're going to get?
