Heres with car lowered back on the ground. You think itll be ok?

What do you think a GT3076r compressor wheel mated to a GT30 turbine wheel will flow in a mitsu bolt on housing?

It's kinda a steep angle for the hose....you can probably replace that 60* fitting with another 45* and they'll probably line up just fine.

What do you think a GT3076r compressor wheel mated to a GT30 turbine wheel will flow in a mitsu bolt on housing?

Depends what turbine housing you're using, and how well the turbine housing flows. Look up user results for the SBR GT13, AGP L2R, and FP 3052.

I got them to line up perfect and a different hose is on there and i zip tied it good. Is that angle too shallow?

I've done a blt good until 25psi but I'm going to see if my MAF is dirty or something is causing a restriction. Thank justin

Angle good?

 

[JusMX141]

Looks good to me man, as long as the hose isn't pinched on the inside of the angle you're good to go.

 

[Archer Fabrications]

The gap is 4mm between fittings, I'm good as long as the total angle is up to spec.

 

[Archer Fabrications]

The 60 fittig bound up and doesnt swivel an leaks a little oil, gonna jb weld it since it's seized anyway haha just on te outside where the swivel is.

I'd order new fittings but i hate importing things to canada, no one up here has push lock

So my 1G BOV is leaking which I believe is causing the MAF to be choppy. I recall when I did my BLT test to 25psi my BOV was leaking through the recirculating tube (the vacuum hose from the IM was on) But it was leaking from the moment I started the test and I had to increase the psi from compressor just to get to 25psi (probably overworking turbo smh). Would you say that could be the reason for the Choppy MAF Raw?

Thanks

 

[spadepro22]

I couldn't really find the info I was for, but I think its in a 7cm housing. In that housing would I be better sticking with my 20g?

Absolutely. Inconsistent boost = inconsistent airflow.

Do the Dodge Garage Mod to your valve and never look back.

It still has a larger turbine than your 20G, so it would likely flow more regardless.

Awesome! Thanks For the info

Quick turbine question. Does the same rule apply for the compressor wheel as it does for the turbine as in blade spacing and airflow? What would happen if turbine blade spacing was minimized and the housing gap minimized to combat lag, it would lose power in the upper flow ranges right? Having a debate with a friend and needed to ask.

 

[JusMX141]

Less turbine blades = more turbine flow as there is a wider gap between the blades and more space for the airflow to fill....more exhaust flow will pass through the wheel with every revolution.

More turbine blades = better spool as there is more surface area of the turbine wheel to "grab" the exhaust flow.

 

[Archer Fabrications]

The smaller things are the more restriction in flow there will be. Yes it will spool faster but it's similar
To say a bep .55AR vs the .70AR the .55 is more limiting because it's smaller. Also think about a 16g, it has a smaller turbine and housing, spools quite fast, but won't make 500hp.

Justin,
I have a 20G/ TD05 CHRA I pulled apart with the assistance of your tech article (Thanks!). However when pulling the thrust bearing out of the CHRA I found a few metal shavings. I know the thrust bearing is shot due to the axial shaft play and blued bearing insert. My question is when looking in the CHRA housing what key areas are there to inspect/ measure to insure that it's serviceable?

 

[JusMX141]

Damaged turbine sealing ring surface, or grooved/out-of-spec journals. You'll know right away if the journals are screwed- the bearing will either fit too loosely or not drop in at all because of raised grooving from oil contamination.

That rtv didn't seal the snap ring opening for some reason if i rtv that opening on the back side of the compressor cover that should seal it right? I mean it's literally only leaking where the snapring opening is. Effin annoying since i just put the turbo back on, i put a very thin layer of rtv on the grove of the chra compressor back plate and around the outer edge, thought for sure that would solve it.

I had the same problem with my hx40! The first time I used a really thin film and it took me 30 minutes to get the damn thing back on. Still leaked, so I pulled it off again and used the "RIGHT STUFF" and was able to get the cover back on quickly and seals like a champion now! I also used a little more silicone that time. Also make SURE that everything is way CLEAN!! BTW you can do it with the turbo on the car, that is how I did it.

 

[Archer Fabrications]

Snap ring is a bi*** on the car, i actually am using the right stuff still leaked, justin said only a small amount so i did a thin film. Anyway it sealed everything except the opening so I'll put more right stuff in there, ( i also use that for my oi pan)

Justin, to rebuild the stock 1g 14b what parts/source would you recommend?

 

[NHerron]

Good question ^ I've been meaning to ask Justin the same thing but for HX-35 parts

Justin, I just picked up a seemingly good HX35 -just a slight resistance to turning the shaft so I took it apart. Everything measured within spec as I recall just looked like a case of oil coking (I know this guy never idled his truck, drove it like a hot Mustang) Truck was the 5.9 12V.

I had a hard time finding a true OEM supplier online (trying to avoid the Dodge dealer, prices seem too high) do you have any advice?

Not sure what guys are using these days- the majority of my parts kits I use are assembled from parts sourced from three different vendors.

Any Cummins Turbo Tech dealer or one of the many performance diesel shops like High Tech Turbo should be able to help you out.

 

[NHerron]

Thank you. I'll see what the shops say around here
