Never noticed any fan wash or extreme temps with the inlet air, it actually was a little lower then the numbers I showed with a P1SC kit on an ATI. I was once very concerned about the way ATI put the filter over the header on the 95-95 car but I had not seen an adverse effects...the inlet temps are still very low and they make great power.
I would build another kit, it took me a long time to get that design figured out with it is actually less air path then a lot of set-ups. I have quite a few idea on ways to run the pipes but it really depends what front acessories the car has, and what manifold it had.. I tried the flip design on that car but could not get the pipes to fit with the large Fluidyne rad and P/S pump withoput relocating the battery etc, and this is a true street car, daily driven at times, so it needed to be very used friendly.
When you open the hood it has the WOW effect that is for sure, one of a kind around here.
