I think it will help. IT rules state that anything in front of the carbs is free - EXCEPT, a cold air intake UNLESS your car had it factory. So, by the book I can make any sheet metal contraption I want and I think, since we know some JH's used that hole for air, I can plumb my sheet metal contraption into the hole for fresh air.
It definitely helps power. It is well known and well documented with dyno sheets that Z cars pick up about 7-10 rear wheel hp if they don't breathe the hot under hood air and instead get a fresh air pickup out the front. Of course, a Z car can make 170-190 rear wheel hp in IT trim, so it is a little apples to oranges on the JH, but the Z car motor is 2.4L where we are at 2.0L. So, we should get something and I am sure temps, carbs, etc. have a lot to do with it.
In short, I think it'll be worth it and I will work to make one, just not right away. I was planning on necking that 5" hole in the body down to 3" and using it for a brake duct feed, but now I need to use something else.
