Classic Auto Air Install Experience

My dad had some PVC pipe laying around, and as it turns out, 1.5" pipe is pretty much just the right size for the hose to slip on to. So my plan at the moment is to cut a section of the pipe and tie it to the dash and then route hose to either side of it. I might get fancy and 3D print some 90 degree adapters on either end to make the routing a little easier yet. I'm also tempted to make those oval shaped instead of round as it is a bit tight between the side of the cluster and the heater controls, so it would save me a little space. Need to mock it up and see what it looks like.

I've been happy enough with the system so far though. Haven't had much hot weather around here yet to really stress it, but did have one day that was 85-90 for the drive home and it did pretty good. It's a bit slow to start and would probably benefit from some better baffling up at the radiator to control airflow better, but once you're moving it's nice and cold air coming out. I have one of my electric fans set to run below ~35 mph to try to help it out, but I'm not sure if it makes a ton of difference. Could also be that my idle is sagging too much and not getting enough compressor speed. I'm still working on the idle in general as it does some funny bouncing around and weird dips and surges. You can hear the thermostat cycle the system on the lowest fan speed. On the medium speed it seems to keep enough airflow to keep it from cycling. I do need to get the other vent installed though as I only really have the one blowing on me, and even though it's pretty cold, it's only so much. It was kind of nice to actually get home and be dry for a change though, lol.
