Hmm... not sure I would trust a 50+lb turbo hanging off the back of another. Are you using the stock manifold? K&N = I wouldn't rely solely on the defuel settings to hold the boost back. Under stock fueling it still might pull past 40. Anything cheap around 100lbs. Shouldn't need anything specific if you aren't running a high lift cam.

Interesting setup.... do they use any sort of support bracket for the primary turbo, or does it just hang off of the HX? I would really like to see some sort of intake tube, rather than pulling the hot air off the side of the motor. I bet one could be fabricated pretty easily. And please tell me that's not a K&N filter on there...... EDIT: Be careful with having stock head bolts and springs!!!

Small fast welds of approximate equal size "should" be okay. The damper has to be good for something right

I think he wants you to post the edited excel sheet where you made graphs. Just a guess though.....

Good to hear it's working and you like it! You can't put a price on the well-being of a family! My parents had tons of insulation sprayed in the attic of their house, and it made a huge difference on the heating bill. They have natural gas and water pumped throughout the house for heat, but that doesn't run very often. They installed thermostat controlled pellet stoves on both floors and they seem to do a great job keeping the house war.

See below Even the fan I took off (which was great before the engine warmed up) is stiff off the truck. ^^^Yup So I headed to a buddies tonight and about 15 miles down the road it disengaged for the first time! After sitting parked at his house for 3 hours or so it was locked up again when I took off. This time it disengaged after about 5 min going slow. Maybe it's starting to loosen up?? We'll see. It has a lifetime warranty, so I'm not too worried.

I'm not happy with the heat. Makes me twitchy too! It did get cool enough I had to hook up side of my grid heater didn't want to piss the neighbors off too much! The heat pump system looks pretty cool Mike. And the house looks awesome, even from the back side!

That's a very sad excuse for a weld! I don't think there's enough friction between the flex plate and the crankshaft to make the force rely solely on friction. If you have 1200 ft-lbs of torque I really don't see friction being able to hold that. Maybe I'll dust off some old books and run some calculations for the fun of it

Can't do that.... With the truck being a tow pig during the summer I need something that'll move a lot of air! I'm going to call Napa and see what they have to say.

Tappet cover gasket.... To fix that you're going to have to remove the tappet cover, which requires removing the VP44. From what I've seen, it's usually not a dirty surface that causes a leak, but rather a slight bend in the tappet cover. That slight bend won't keep enough pressure on the gasket and allow oil to seep by.

I might have a silencer ring laying around, but no snap ring. Let me ask my buddy where he got his. No need to re-balance. Every part is individually balanced.

That's the problem with going bigger. The bigger you go the slower they spool. Just nature of the beast. I wouldn't be worried about that little spot. I've seen worse. The leak does suck though. I wouldn't bother buying another turbo to rebuild that one. You can buy genuine wheels pretty cheap, and rebuilding it is a piece of cake. If you don't want to mess with it my buddy is selling a rebuilt hx35 with 1500 miles for $350, then you could just sell yours. I'm all for seeing how you like it with the injectors first. VGT may be the best way for you to go.... or maybe the hx will be fine and you don't need to spend any money.

Is your current turbo sloppy? Side side? In-out? If it's not, you can just replace the wheel. How bad is the wheel? Can you take a picture? If it's a tiny nick and the turbo is tight I wouldn't worry about it. You'll be amazed what good injectors do to help spool a turbo..... Get the injectors and make a decision turbo-wise after the injectors are in.

So both of the ones I have gotten say made in the USA, which I was surprised by. I have a buddy who works at advance auto, and the ones they have look the exact same as the ones from Napa. Literally exactly the same. I really don't want to go to the dealership....

Mine still does it when the engine is relatively warm but cold outside. My guess is battery temperature sensor is tied in as an ambient somewhere

Do new fan clutches need time to "break in?" I got a new one Sunday night and it still hasn't unlocked by today so I took it back and got another. The new one hasn't unlocked today either so I'm not sure if I just need to give it some time or go get another.

This is a huge update for anyone that wants it to be smooth! Even with my fat injectors I have no puff of smoke when wiretap starts fueling. Honestly you can't even tell other than it smashes you back in your seat. I would highly recommend everyone running V2 download this new one.

My local Cummins charged me $15 to have a front main "shipped" from Denver to Pueblo. That's like 120 miles, and I know they have daily shipments between the stores. What a pain

I think the yellow means low fuel pressure. Not sure why it makes the turbo symbol yellow though. That's my 1 gripe right now.... that dang fuel pressure sensor. I can't seem to root my phone to delete the code that makes it yellow, so I'll have to wait until quad comes out with a v2 no fuel pressure warning on the list of vehicles.

Looks like the boost is more accurate at higher pressures.... it also depends on the response from each sensor and the resolution of the quad. I can't go over 55psi right now though due to my crappy intake horn.

Fun fact.... The 02 sensor is no longer made. You have to use an 01 sensor with an adapter.

As am I. The stock MAP follows the "fuel" pressure sensor up to 60 just fine. All 3 of my gauges are very close to each other.

It's right on with my fuel pressure sensor which is good to 100psi. Have you ever seen one that high in person?

Those pressures won't hurt the map sensor. Put mine into the Low 70s multiple times and never had an issue. Stock 02 sensor will go to 62psi.

So... in theory lower timing helps spool turbos faster. This is still in the test phase for 2nd gens though, so no guarantee on whether it will work well for you or not. You could increase your Low Psi Timing Reduct and possibly see faster spool. Like I said earlier though, you likely won't see see a benefit because your spool should be the same as the hx. Once the HX lights, it'll help get the 66 moving.
