Sounds good @speakerfritz . I'd also replace the cold side hose if I were you, since that one is prone to blowing up.

 

You could pull the turbo and replace the turbine and compressor wheels with aftermarket, like what's been discussed here before, to move more air...

 

I don't remember that from my truck when installing the DPK...

And yeah, truck sounds good...

 

not necessary

all you have to do is cool the air using the existing architecture.

cooler air is more condense and allows for more power

you can vary the methonal content to tweak the plus power

 

on a 2017 to 2019 if you follow the degas hose backwards to the firewall you will see this brittle T-fitting. I literally just moved the hose out of the way and it snapped.


i super glue gelled it…then I used copy cat job well with aluminum particles. So I’ll leave it and not soft about it.

 

also

while I had this apart…I checked the T-25 screws that hold the DPK and I got an easy half a turn on them with a T-25 tee handle. Not sure if they just got loose or if I don’t tighten enough . I been bench curling a lot of beers since I retired in February and I’m probally stronger now then when I put the DPK in.

 

I have both a hot side and cold side kit.
The cold side kit has a manifold with 3 npt ports for my methonal injection kit. Yummy.

i might install these tomorrow morning if I am not sore from today.


after I install the npt manifold…1 stop away from installing my methonal injection kit.

 

I wanted to do a basic test.

Thinking that a static regen should provide useful data


i normally have 6 to 9 percent soot left after a static regen. 9 or so when it is warm to hot and 6 or so when it is cool to cold.

today at 88 degrees I have 4 percent left after a static regen. The truck had never finished a regen that low. So yes…it’s definitely flowing more air .

lower right hand corner is percent dpf soot .





now I am wondering if I get a dpf. Ack exhuast ….will the soot level remaining after a regen go down even further.

 

It’s been idling for over an hour

At 5 percent dpf soot level


used to start clicking up wards on percents if left idling for a while.

 

Idling for 90 minutes

 

DEFinitly burning more def

it was at 3/4 point 90 minutes ago

 

Over 2 hrs of idling and still at 4% dpf soot level. Truck has never done this. Would have been at 15% soot level if idled for 2 hrs.


so what have I learned today

engine sounds like a diesel

creating less soot

using more def

generating more engine bay heat….ordered some heat proof tape to wrap the wires and hoses….could be hot just becuase it’s idling and not moving thru the air.


plans

finish cold side and hot side tube installs

finish methonal injection install

wrap wires and hoses near the pusher intake with heat proof tape. Call pusher to see what they think about the super hot engine bay. I never hear gun the stock setup so I don’t know if the heat is normal.

get a dpf back exhuast. I think the 6.7 stock does not breathe well and I am curious to see what the dpf back exhuast will do to regen remaining soot percent.

will probally get a vented hood…had one on my prior truck and it will certainly help with engine valley heat.


time for a bath and dinner.

Some heat readings along the piping.

 

Doing upgrades like this is never necessary but I can see the point of making a stock turbo move more air than it did before with the addition of aftermarket turbo wheels designed for that purpose...

More efficient at moving air as air acts like a fluid... especially since adding a more efficient intake system... But that would require far more R&R with removing the turbo for that task.

Like on a boat with an aftermarket stainless steel prop on the outdrive that will slice through the water easier (essentially "move" more water) to make the boat faster either out of the hole or on the top end depending on how the prop is pitched ; and even an aftermarket stainless impeller in a jet ski jet pump that will either pull the ski out of the hole quicker or more speed on the top end depending on how it's pitched also...

Just using the water vehicles as an example to make my point. So while methanol injection will cool the air, making it more dense, that the stock turbo moves, moving more air and cooling it will result in a denser, larger mass of air entering the combustion chamber. People can correct me if I'm wrong.



All this stuff costs money and time... Plus the need for another vehicle if you're not wrenching on it all in one or two days, probably longer if the turbo was pulled and going to be rebuilt by you or someone else... It sounds like it's a beyotch to pull the turbo when the cab's still on by what I've read... I have no clue as I'm just learning more about this stuff as I go.

Good job Fritz... Looking forward to the methanol injection system install... That'll be more learning for me.



Well, good luck with that buddy...

I know that's the SPE cold pipe. You have their hot pipe also or different brand?

We were hot yesterday but today was gray, raining and about 65. Much lower humidity also... I can't stand high humidity...

Still haven't done a OCR yet... I.might have to for schitts and giggles...
