OK - just read up on what configuration the valves should be in for "normal" operation of the I/C isolation kit.

From the NeedsWings web site:

Kit is to be installed with valves open, take the car through a heat cycle to purge out any air bubbles that were introduced into the line durring the install. Once the car has had a chance to purge out all the air bubbles the valves can be closed, which isolates the 2 systems.

So, it sounds like the iso kit is in the proper config for maximum S/C output. That being said .... +4 on the I/C pump replacement
