Nice build and plans but I'm at a loss to understand why you did not take the opportunity to build a stronger engine bottom end now that you have the engine out? A forged low compression piston and rods set (eg wiseco), new bearings, uprated gaskets, rev up oil pump, new water pump and ARP main and head bolts will get you an engine that will safely handle more more and last a long time with the supercharger fully exploited.
Secondly lightweight crank pulley set is a bad idea especially for FI. Stay OEM or buy a harmonic balanced pulley eg Fluidampr.
I don't know how humid it is in Iceland but I have a full AC delete with my SC set up and I have no problems with dehumidification here in the UK and is difficult to say if the car revs faster as I did it sametime as the Vortech but I regretted not having AC in summer as some days were so hot!! I'm putting it back! WRT cooling I'm sure there is some benefit but if you have an oil cooler, low temp thermostat and bigger radiator like I do then there is not more to gain from deleting the AC. There is no significant weight gain unless you remove the compressor which is quite heavy.
Hope every thing goes well for you.
