Making Cold Air Duct For SRI
I have the JWT popcharger and was thinking of a simple cheap way to turn it into a cold air...
Sawing out the same area around the battery for where the place racing intake would go to pull outside air from the fender well, and installing flexible air duct (insulated maybe to keep the temps cool), and make a flat mating surface at the neck of the popcharger to make it air tight. All of the air would be pulled in from the fender area and still have the advantage of the shorter intake and velocity stack... thoughts? The bigger the tubing the better for more available air to be sucked in? Would 6inch be enough or should i go 8?

So other than sucking your wallet dry does this magical device do?
Have you already cleared all codes, replaced all the plugs, and upstream oxy sensors, cleaned the egr pipes, and checked the knock sensor?
Have you replaced or serviced the injectors?
If not, start there. You might find the horse power which Nissan put there for you.

I don't think your idea will still be considered a SRI. Gains will be minimal at best. Much bigger gains are to be had with either a MEVI or 00VI

25ft of flexible insulated ducting for $25 http://www.homedepot.com/p/Thermafle...g&gclsrc=aw.ds
I'd say it would be the cheapest and easiest mod on the car, keeping the advantages of the SRI while at the same time getting rid of the hot air intake and sluggish takeoffs. I read this would be the "true" definition of a hybrid intake somewhere on here (short ram with the cold air duct)

Damn i just had my manifold off and painted and put new injectors in, i checked out tatankos site and now as bad as i wanna do the 00vi swap i wanted my next project to be a 3.5 swap after I've saved up the money 
and idk what i thought i had read but what i was reading last night along with those graphs no doubt the 00vi is better, wish i would of seen that graph a couple weeks ago no doubt i would of done the swap

But look at it this way. 4th gen Maxima with 3.0L engine is rated at 190HP. 5th gen Maxima with 3.0L engine is rated at 227HP (5spd) and 222HP (4A).
What's the biggest change? The manifold.
The biggest NA gains to be had with the Maxima are the manifold and the Y-pipe.
