Been hammering on the car today, here's progress:

Hot side of the charge pipes, feeds from the turbos.   These "T" together and then come up over the crossmember:



Here you can see the "T" and where it comes over the crossmember.  It won't rub once it's all tightened up:



Over the crossmember, this is a coupling joint where it comes up and will allow a bit of flex:



Heading up alongside the radiator toward the intercooler:



There are 90* 5 ply silicone couplers that go through the core support to tie the charge pipes to the intercooler:





So, I mentioned before that I murdered the two 90* bends I had purchased when I was learning to TIG (well, I'm still learning).   I was going to buy more, but I thought, hey, I'm an idiot, maybe I should build some pie cuts.   So...   here we go...     To make the "slices" I put a marker line down each side of the tubing, 180* apart.   I then put a pair of marks on my band saw mounting clamp that lined up with the two marks on the tubing and set my angle to ~17* or so.   I cut one side, moved the tubing out about 4" and rolled it 180* to the new marks and cut again.   Repeat a... bunch.   Voila, identical slices for the pie cuts.

I'm finally starting to get better at tacking the pipes, I probably got 90% of these tacked up on the first try, so that's good progress.   :)

Also in these pictures is my wigger clamp (eBay Wiggins clamp) on the throttle body.   Welding nasty cast throttle body was not a ton of fun but it came out alright.   The transition piece was some kind of nasty aluminum and just welded ugly, so I did two layers and ground it back smooth, this is all getting wrinkle finish black anyway, so it should look alright when it's done.

Pie cuts!





I'll finish these up tomorrow, I already have the segments between those pie cuts fabricated, just need to clean them up and tack them in, then finish weld all of it.    After that is exhaust system, then back to bumpers and finishing up the front valance tweaks.   I'm getting dangerously close to paint prep time.

Those welds are looking like mine now... the first couple were better than mine though. lol

Try to put the pie cut piece in the oven for a little bit before you start welding, its been easier for me to weld that way too.

mmm tasty pie cuts.  Nice work on the charge pipes, Are you going to clearance those holes for the silicone couplers more?  I would hate to have a boost leak from that

Thanks!     They'll be clearanced to make sure it's not a problem.  :)   They're just rough cut right now.

More progress:







And the bumper on with the valance.    Figuring out order of operations on this with everything tightened up, fitment wise, is a pain.    I think I have it sorted out.   The passenger side bracket setup is all welded up and the driver side is tacked up.   I added some reinforcement braces, because, well of course I did.

LOL, I am probably painting the IC black to tone it down also.   I'm actually really, really happy with how things are shaping up in the front.   I wish I had larger than 2.5" charge pipes, but the math says I'm fine for flow vs. HP vs. mach speed in the pipes, it just looks odd with 2.5" stepping up to 3.5" at the throttle body.

Oh, I didn't picture it specifically but there was a steam vent of sorts on the upper coolant fitting on top of the motor.  It was damaged in shipping and, per my reading, not necessary since my radiator is higher than the engine anyway, so I went ahead and welded it shut.   Welding nasty cast metal that's had coolant in it sucks.  Haha.   I'm now thinking about replacing that part and putting a valve on it so that I can "burp" the system.   We'll see if it's an issue.

I was gonna say, those cold side pipes look small... especially compared to the throttle body.. lol

Yeah, to fit beside the radiator I'm limited to 2.5" pipe.  In fairness, that's all my intercooler is setup for anyway.

If you have a second, what calcs, rules of thumb, etc. are involved with cold side piping?  I know you want to reduce overall volume in that system, and of course packing the pipes into the available space.  I just have not run into any solid info on how small is too small, and diminishing returns of too large.

1200 cfm = 277 mph = 0.36 mach
1300 cfm max= 301 mph = 0.39 mach

Remember that CFM is independent of density.   Figuring N/A 425 flywheel HP, 2.2 cfm/HP, that's around 925 cfm, which is about right for 2.5" piping (right on the edge, but going a touch over isn't the end of the world).   Now figure I want 650 RWHP.  That's ~765 HP.   If I'm running ~11 lbs of boost at the same relative air pressure, I'm flowing about the same CFM of more densely charged air.

Essentially I may need another lbs or so of boost because of smaller tubing, but it's unlikely to be a limiting factor in an engine which has a maximium bottom end capacity of ~800 flywheel anyway.  FWIW if I went to 3" tubing, I'd be required to add ~5 more 90* bends and 2' of length to it, which would negate some of the efficiency of my minimal bends/short length system.

It's been my experience that added volume, within reason, won't lag things much - the space fills quickly. A friend who makes intercoolers for 911tt has also found that while larger pipes will flow more they also flow faster and the air spends less time in the intercoolers resulting in less temp drop at the exit. There are some interesting differential temp sensors you can use to see inlet, outlet, and difference between to monitor what's going on. Fun stuff  8)
