74 Challenger with twins

[YellowThumper]

Finish welding more of the cold side. More grinding than welding though.
Compromises everywhere. Wanted a smoother sweep into the TB, but intake tube is already close to header. Plan on welding tabs to it for mounting yet another heat insulated shield.
Top portion of tubes show are full welded. Left bottom open to allow for puddling the inside also.
Bottom cap will be lapped and can remain "ugly" and not seen.
Completing this portion was not in my immediate plans. Change of plans because as I am learning and dialing in the tune, I figured no need to "learn" twice.

Being a bit burned out on cold half welding, I moved sideways to fun stuff.
Finally fired up 3D printer and made these air intake ducts.
Currently only PLA for cheap testing and refinement.
But... is it cool.
Next up will be interface adapter cone that tucks behind headlight ring and holds everything in place.
Inside area surrounding filters will be boxed in with aluminum.

Modeled and printed the headlight cone.
Looks terrible in black.
Will try grey or silver similar to grill.
May add a bit more curves to tapered face.

Redesigned and installed the cold air ducts. Better than the first black ones but still not 100%. Have plenty more pressing items so they are good enough for now.
Finish welded the cold half ductwork. Added blow off valve and bung for AIT. Upper visual side is welded outside and inside to provide solid weld for grinding weld smooth. Bottom face is just lap welded to keep as much weld as possible. IE keeping the ugly on the bottom.
Couple more small details and it is ready for some added atmosphere.

Full closure now for boost.
Reinstalled the hood latch. Was removed to keep my scalp intact.
Reinstalled rear interior panels and back seat to help "find" space for the myriad of items that have been stored on it.
As I still will be working under the pass side dash for a/c install and wiring, I mounted the passenger seat front bolts into the rear seat holes. Basically pushing it all the way back towards rear seat.
Made a platform for laptop.
Icing on the cake was a casual drive around the block. No guages or laptop were hooked up. Only afr guage showing it running rich.
First time out in a year and a half.
Still smiling...
Lastly was to relocate it's parking to the left side of garage. This is the "active" side. Due to close quarters, left one has to be pulled out first to allow right side to be used.

[YellowThumper]

Pulled dash pad for ease of working under it for all the wiring and a/c system install.
Then, of course I had to get distracted. Time for some added vent holes. I find it easy to hack items up that are already in poor condition.
This will also allow for testing the newly printed pieces.
Further distractions are the hood inserts. I have added a lot of heat to engine bay. To alleviate some, I cut open the back sides of spare inserts. As this is a low pressure zone, I am hoping it will help. At minimum it will allow for dissipation once car is stopped. Eventually I will increase opening further. Along with adding plugs if i have to drive in the rain.

Mostly happy end of year.
Unfortunately have a leak on one turbo drain.
Overall very pleased. Been a long time coming.

Love it !! 

Really like the exhaust dump.  That will be awesome when you finish it I'm sure!

What is the squeaking?  Bearing? or body parts rubbing?

Believe it is the idler pully bearing.
That and exhaust tips are on the long list of smaller future issues.
Tips will tuck in much further than shown. May also trim face at a slightly inward angle once I get the tail panel closed in around them.
Rear bumper mounting brackets are done. Purposely mounted it too close to body and use shims for final positioning.
If you can zoom in close enough, you can see my factory bumper jack instructions are upside down.

Trunk sticker guy must have been taking a nap in the trunk before he put that on.
Pretty cool to have that kind of factory mix up.
