      FYI for those following along on the DCT aspect of the project;



      Domiworks reached out to me about by project. I am running an LTx block, not an LS. For those not familiar, the LS and LTx blocks have a different bolt pattern on the top two bellhousing bolts. I was just going to leave them blank, but Domi asked if we could work together to modify the adapter.

      The plan is to add the additional wholes for the LTx to the LS adapter in order to make it a universal component. Ill keep you all posted on the progress.

      So i haven't posted recently, but there has been some progress. I got the engine and transmission pulled from the truck. Also got the whole front end of the truck removed and stored for now.
      This week i made a small transmission crossmember for the DCT. There is a plate that bolts to the trans, and then i use Heim joints with studs mounted through a rubber bushing to attach to the crossmember. The crossmember is very light, but should do the trick.

      I also bought a Dry sump pump so that I can get the spare engine ready for mockup. Its important for the mockup that all of the big accessories are in place. That way I can get the engine position and clearances just right.
      The pump is a Frank Weiss Racing Components 5 Stage Helix Rotor pump. Its a nice billet piece. The pump came with nice stainess tubing and BMR lines. Unfortunately its cheap to get rid of that stuff and go straight to AN hoses than it is to buy the needed Wiggins clamps and fittings to wrap it up as it sits.

      Dry sumps are expensive lol. Ill have 3x as much in fittings, scavenge filters and hoses than I do into the actual pump.

      Last thing i did was pull the rear out of the truck and modified the panhard bar and coilover mount to be in double shear. The single shear design was strong enough according to my calcs, but this is a just extra heavy duty.

      Got a good bit of work done this weekend.

      1. Tore down, cleaned and polish out the dry sump. Just making sure any scuffs on the rotors werent fretting
      2. Mockup 3D printed dry sump mount
      3. Got my up and foward LTx headers in and full purge welding in the 8 EGT bungs. This was my first time welding stainless, learned i need to speed up!
      4. Got all of the cab mounts cut out, welded up and mounted on the chassis. I made some nice little measurement gauges on the 3D printer to help locate them. Worked out great.

      Gotta love having a 3D printer, you can make all kinds of useful tools and mockup parts....

      Well I got a lot of parts in and a good bit of work done.

      Turbos showed up:
      VS Racing
      67/62 Billet Dual Bearing Turbo
      1.01 A/R VBand turbine housing
      Mirror image
      Water cooled

      Got dual 50mm VS Racing Wastegates as well

      DomiWorks Engineer Adapter for the transmission showed up. What a sick piece. Super nice.

      I also purchased a Holley Hi Ram with the PFI port provisions.

      Last week i stripped the cab, and mounted it onto the chassis with some homemade 70A urethane bushing. They are sleeved with 1"x .1875" steel tubing to keep the cab from shearing off in the event of a roll over or T-Bone.

      Next up... engine mounting and turbo hot side piping.

      Another forum asked the question... why EGTs on each cylinder:


      It will have EGT per cylinder and Widebands measure AFR on both headers. Widebands will measure the bulk AFR of each side (4 cylinders). Since the MaxxEcu can run closed loop, it wont tell you if an issue pops up with an injector.


      Imagine im targeting a .82 Lambda, and the engine is all happy. Great. Now say I pass a speck of debris into one of the injectors. The ECU will see that the bulk AFR in that bank will climb slightly, and it will try to make a correction to all of the cylinders in that bank. The bulk AFR will come down to .82, but 3 of the cylinders will be rich and one will be lean. No bueno on a high boost turbo setup.

      Having each EGT measured allows my to put safeties in the tune that say if Cylinder X is Y °F away from the average, throw a warning. If cylinder X is Z°F away from the average, Throw a warning, open the wastegates, pull timing, and dump 30% fuel enrichments almost instantly.

      The ECU is sampling non stop. It can react faster than i ever could to a change in power or sound. You just have to provide it with the inputs it needs and the logic to do it.

      Putting telemetry on the engine and programming safeties prevents me from burning down the engine.

      Yup...that is spicier!!!

      Does the MAXX ECU have closed loop individual cylinder trims?

      The forum software does this when the same person makes a post in the same thread within a certain period of time.

      So I got some stuff done lol.
      I started working out the turbo turn downs on the hotside. .080"w 304 stainless, and fully purge welded. This is my second time trying to weld stainless steel, so im pretty happy with how it turned out. I think im going to have to cut off the wastegate flange and add a 90° elbow. The waste gate just sits too far forward. After messing with that, I started working on getting the engine fitted up.
      It is 4.5" farther back than stock. I did this for weight balance and turbo packaging. Unfortunatley that will mean fabricating a new firewall and trans tunnel. Ill get it hashed out lol. I ordered a bead roller this week.

      Big ole 14.8" CTS-V brakes are on. These are one piece for now. Theyre actually 2#s lighter than the later 2 piece units. In the future I may mix it up. We will see.

      I dunno man.... I think your CNC skills, welding skills, and overall level of patience might just be.... oh... I dunno....
      ABOUT 1000 TIMES better than mine.
      Dude... I tip my hat. That video .... wow.

      Thanks a ton. I always have had the philosophy that being a jack of all trades is more useful than being a master. Being decent at design, fab, welding, wiring, programming, bodywork, painting and mechanical worth is better for me than being a master at any of them.

      Next skill i need to figure out is sheetmetal fabrication. That firewall hole is mocking me. Lol.

      My sentiments exactly
      I'm impressed with your finish welds. I've welded for 20 years. Mostly carbon steel on heavy equipment and water towers as I build and rehab them but it requires mechanical skills, electrical skills, hydraulics, welding, estimating, bidding, PR skills etc. Jack of many is very handy. I wouldn't say I try mastering any but try to give 110% while doing any. I put a. Floor from my toes to tail pan including mini tubs, narrowed frame rails etc on my build and have never welded sheet metal. A real body and sheet metal guy could critique it yes but it's every bit as good as paying a shop a five grand or whatever it takes t get done. And I got the feel good of doing it.
      Hats off to your tenacity

      I got the transmission in and mounted. Worked out great! The Domiworks engineering adapter went in relatively drama free. Some minor cutting and she's in.
