Thought about where the filter will go?
As long as I make it wide enough, the cross sectional area will be similar as I'm only needing 3" diam equiv. So it looks fine.
Filter will be right in front, creating a box section behind the radiator, slightly angled down me thinks.

Re: ITB and intake temps
I played around with the first air box that I purchased for the ITB's and it is possible for it to fit!
Separate the filter, this allowed the locking nuts to be orientated to the top

However, with the PWR water/oil combo the filter box hits on the hoses, however it will fit. All that would be needed is to sikaflex the two parts back together. Although it still points towards the radiator ducting could still be made to get cool air from the hot side. Heat could be minimised by using something like this http://www.thermotec.com/products/14500-cool-air-tube-heat-shield.html

Re: ITB and intake temps
From the recent track day with the NACA duct I have found that the average difference between the outside and under bonnet temps have decreased.
Jap Nats----------25.8 deg diff at start
Time Attack -----19.8
Jap Nats -------- 32.2 after about 5 mins
Time Attack------20.2
Jap Nats---------36.1 in the pits after cooldown lap
Time Attack-----26.8

Re: ITB and intake temps
The air box is not in, I'm still using the Pipercross dome filter. It will fit on a similar car if it does NOT have the same PWR radiator that is in mine.
The sensor for the ECU is located on the base plate that the air filter or box attaches to. The sensor that I have been using for data analysis is located on the outside of the dome filter.
