2-Stager unit

[before]

I've removed the CPEV from 2nd stage, and try to get a good amount of R1150 in order to achieve some decent temperatures. (CPEV is now used as a 1st stage expansion metric for my 3-stager)

First tries weren't very good cause without CPEV I've lost about 10C+, pressure for pressure, load for load.

So, I've though that it was time to remove the remaining captube which was used along with the CPEV (~2m of 2mm + ~2.9m of 0.9mm). Was thinking about 3.5 to 3.6m of 0.9mm as a replacement.

But today morning, before changing the captube, I've decided to go for a bit less of R1150... and I finally got pretty nice loaded temperatures... at about 5.6GHz using 1.97vCORE for Spi 32M, top/'hotter' part of the evaporator shown -103.5C with an evap pressure of 0.6bar which means -112C.

Well, that's nearly the same than it was with the CPEV installed, that's damn good considering the load.
