As I recall, you have a ROE kit. If so, you can use a pressure gage to monitor the pressure in the ROE intake tubes feeding the SC with the airbox/tubes/filters/etc on and off the car. If you don't see any noticable drop in pressure on your intake tubes, the SC is getting all the air it can. Opening up the air intake side won't generate any noticable power increase.
As an example, on my Gen1 6.5lb ROE, I made 600RWHP. At max HP, there was a substantial drop in the intake tube pressure. I only have stock TB's and smooth tubes. I'll be upgrading in the future, and will post before/after dyno and tube pressure results. The 'guestimate' on HP loss was ~30RWHP.
Hot air vs cold air is a completely different scenario from restriction. I haven't talked to those 'in the know' about it, but I would suspect that the heat generated by the ROE SC in compressing the charge will far outweigh any increase in temp on the air into the tubes. A very cold intake air temp might make a small difference, but I would think anything else would be un-noticable. The SC is going to compress the air to a given pressure/heat capability based on the pulley.
I believe that on a NA car, colder air matters more, because that is the governing item related to total volume of air taken into the cylinder (heads, cam, intake port, etc. all being equal).
