Hood mod

I just went out and looked at what the OP might be talking about, I really doubt drilling a hole in the side of that little tube will "ram" very much air through any intake. I also doubt it'll affect the airflow through the tmic if anyone tries this out.
 
I'm wondering if it's worth having the ducting to the battery, or if we simply took the battery out of the plastic box and blocked off the tube to it if that would help cool the IC
 
I very very very highly doubt it. Just creates a pocket of nice fresh air around the filter area. When it was still hot and I was racing the mazda at the track i was popping the hood right after my runs and the intercooler was suprisingly very cool to the touch. Along with my intake tube. So I think it helps pretty good for keeping intake temps down on sri. As far as a cai goes it probably would help just he same. keep the tube from heat soaking.
 
the pics definitely help clarify what you were trying to say about it... I was thinking and actual hole in the hood, like the top part, not the ducting, lol

I thought you meant something like this but in the hood

I went out and did some more testing today. made like 3 pulls through the gears and then popped the hood to feel how the intake pipe, intake manifold, and intercooler felt. Hotside of the intercooler was actually not to warm. Cold side of intercooler was actually very cool to the touch and the intake manifold was cool enough that I would let my two year old daughter touch it. Now the intake pipe on the other hand was very very cool. I wasnt totally shocked because thats pretty much exactly what I already knew it was gonna be like. So any nay sayers I assure you that cold air going right over the filter and pipe once you get up to speed. I believe this was a very good mod. Cant be hurting any, seems like my ms3 is running very very good times and putting the hurt down on alot of respectable cars.
 
IMHO the difference "if any" are not going to register on a dyno - even if you blew air, etc the delta diff between the two as far as HP gain is going to be within the margin of error of the dyno itself....
