Unless I use a bunch of washers the space the spring type governor down enough to match the boost comp housing.... might do that instead, I prefer the response of the spring over the cage governor.

Made a throttle shaft shim today. Will put the oring where it should be and keep the lever flush.

Also I got a Subaru turbo flange to weld on, that'll improve the exhaust leakage, it's like running with a wastegate slightly open. It's getting cold too so I can't keep driving to work with all my windows down

I'm thinking of removing my resonator to maybe hear the turbo whistle better. You can faintly hear it if you stand behind the truck and rev it but id like to hear it from the cab. Any of you guys running a straight pipe? Right now all I have is that resonator in so I'm worried it'll piss off the neighbors.
 
with window open my tubo makes alot of noise, but not "piss your neighbors off'noise
 
Did some work over the weekend.

My 'custom' turbo adapter, very proud of this one, I should sell these!

No, the proper flange came in the mail.

Much better, not bad for my 112 volt flux welder, can't wait to get my Lincoln tombstone up and running again.


Turbo is spooling much easier now, I make 4 psi effortlessly. I only build full boost at full throttle, I assume thats normal? I'm fine with it, truck is happy, not chooching smoke, and staying cool. I found the last exhaust leak coming from the bottom of the manifold itself now, so I will have to take a look at that, and probably replace the gasket.

I am having to hold the glow plugs a bit longer now too, one might be going out again, if it's too short I get a miss in one cylinder for a few seconds, oh well, nothing to worry about now.

Looks great; nice work! Sounds like it's running well.

Sounds like turbo is doing what it should. What is max boost? In my truck I don't reach maximum boost until maximum throttle and more than 2200rpm. But I think that's because my waste gate is tied closed. I guess if the waste gate opened, I would hit max boost without full throttle.

I've had miss problems over the years while starting. Most common is a small air leak somewhere. But can also be imperfect cold compression. Or glow system issues like resistance in the current path delivering less power to the plugs etc.
 
Yeah I can hit around 10 psi for a few seconds around 2500RPM, then the governor pulls back on the fuel and boost. It'll hold 6 all day.

Its probably more a matter of adjusting the fuel pin. More spring resistance will prevent it from hitting fuel cut so easily. I'm foggy on this, but is there a 'star wheel' or something to increase spring preload in the boost comp?

You should tune so it can hold 12psi. That should be fine with no intercooler. With intercooler, 20psi+

Oh yeah, think it's called the smoke screw. My cap doesn't have one for some reason.

No, thats different. The adjustment at the top is to set starting point of the fuel pin.

Just looked into it for a second and star wheel is in the bottom.

Usually there are three variables you can adjust on these pins. Turn it for a different fuel ramp (if eccentric fuel pin). Preload it appropriately so you get full travel before it hits the end and pulls fuel. Finally, adjust start position of the fuel ramp by a cam plate or screw in the lid. With some playing around, you can really dial in performance that you want.

Oh okay I see what you mean. I was talking about that cam plate/top screw to adjust the start position. I just don't have one haha. I'll try and source a lid that has one.
 
the black valve cover looks so much better than the blue!! glad to hear your getting better boost now..
my setup would start making boost almost immediately make boost and would even keep 1- 2psi when off throttle on the highway.

10psi was part throttle and 20-25psi flooring it under most conditions although I could get it to spike higher.. It would hit 30 every once and a while if I whacked it in 4th with the AC on up a hill..
sounds like you have meat on the bone still...

also I had a electric cutout to bypass my muffler, I was amazed at how little the muffler did and wound up leaving that open 99% of the time
 
I painted my 3b rocker cover black too, huge improvement
ya, a muffler is useless with a turbo
i put on a straight through dynomax in an attempt to be somewhat civilized...shoulda saved my money
 
Well I drove home like this

The word I would use is... Nuisance

Hehehehehe

I think I'll just cut the resonator out and call it a day. I don't need a VI on this thing.

I still have a fairly large exhaust leak between the head and the manifold, enough to blow a bunch of smoke when I blip the throttle, thats most likely where my boost is going.
 
yup, you need the magic smoke to stay in there
 
Exhaust in video sounds fine. Timing sounds advanced though still? Hard to tell on my phone speaker.
