Triple Blowthrough Turbo

That looks very tidy. Are you planning on adding some slip on insulation to those eventually? I'd imagine the stainless tubing will sweat a ton without it. 

 

It's actually AL tubing but I was using stainless instrument benders to bend them. That's a good point on the sweating, I actually had the same question and emailed Vintage Air tech last year here was their response: 

 

"The only line that should sweat would the #10 suction hose/line, make sure this branch is insulated on the hardlines or metal sections of the hoses that are inside the cabin." 

 

So it doesn't sound like any of them should sweat but I'm not AC expert. I'm sure some insulation on the appropriate branches would increase efficiency so I may consider it at some point but I'm just trying to get the car back on the road first.

My workspace is a mess so this evening I started cleaning up before proceeding so I threw the intercooler back on to check clearances for the AC and oil cooler sections.

 

I think everything looks good to continue fabrication. My welding station is currently set up for AL which it never is so I've been contemplating also hard piping the intercooler with aerospace wiggins clamps. Not sure if it's worth it for this ebay special as the clamps and separate weld ferrules are eye bleeding expensive but I'll simmer on it over weekend projects.

Yes, sorry, aluminum. I somehow missed that you had flexible lines running through the fresh air duct that are already insulated. That's genius. I was already planning on running my wiring harness through the passenger side duct, but hadn't thought of doing the same with the AC lines. I might have to copy you.

@calZ I actually got the fresh air duct idea from the v8 subforum here a few years back when brainstorming the AC setup. I don't recall the thread but it was a super clean silver Z and they ran the lines across the rad support to the pass side. HybridZ is an absolute goldmine of info so maybe someone will stumble across our discussion too and get some inspiration. 

 

There's a lot more going on with the AC install on this build I've been working in the background including inside the cabin (I'll update that ongoing thread in the Interiors sub sometime) but I've been trying to keep this thread mostly dedicated to the turbo aspects.

 

For the cooler packaging I intentionally wanted to keep all the AC componentry all on the DS and the oil cooler all on the PS with the intercooler in front of and crossing between the two instead of single sided. So that's why I went through all the fabrication work so far...it would have been a heck of a lot easier to mount the oil cooler in front of the intercooler, run the AC lines much longer onto the other side of the car, etc. but that wasn't the vision
