Custom CAI for SC was a success!!!

Custom CAI for SC was a success!!!
Summary:
Details:
Stillen's 5th gen supercharger kit has two piping, intake and charge. The intake piping routes from the sc to the other side of the engine near the battery and the charge piping routes from the sc to the throttel body.
A few other people and I thought that the intake piping was useless and may have been a cause for underboosting (not getting the normal about of pounds per square inch of air). Also, since it's right on top of the engine, all the air gets hot before it even reaches the supercharger to get compressed (get even hotter).
So this Saturday I decided to take off the intake piping and relocate the MAF and filter between the fender and liner (like the Cattman and Place Racing CAI setups). The biggest problem was finding the space to put the MAF tube AND filter in the area (in addition to new piping). 4th gen Maximas do not have the problem of relocating the MAF tube and sensor because it is integrated into the charged piping.
Before implementing this project, I had to make sure there would be no problems with extending the wires of the MAF sensor. Many members gave their opinions and all of them said there would be no foreseen problems with this. Thank you all that gave your opinions (you know who you are).
The first thing I did was to take off the intake piping... which was easy. Next, I removed the MAF tube and the filter from the piping... another simple job. Since I had to work behind he fender, I had to take off the passenger wheel and opening up the liner... simple.
Now the ticky part... I wanted to keep the option of using the windshield washer fluid, but had no room for the MAF tube and filter so I had to take it off. (At least I'm lighter now hehehehe) With the reservoir out of the way there was PLENTY of space now.
I test fitted the PVC piping and did a mock install to see if I had any clearance issues. One thing I noticed is that the hole near where the reservoid used to be had to be enlarged. A Dremel and sheet metal cutter did the job. Since the edges were sort of sharp (even after grinding), I had to put something there to protect the new piping. I got a tranny hose and slit it down the middle and wrapped it around the edge (got the idea from the PR CAI).
The PVC piping fit perfectly, but it wouldn't have cleared the wheels (angled wrong). If I turned it so that it cleared the wheel, then I wouldn't have been able to put a connector on the end because an area on the piping had to be squished a bit. Jane and I went to PepBoys to get some intake hose (sort of like Shop-Vac hose) to overcome this issue.
Now, clearance was no longer an issue. The MAF and filter fit perfectly. Extending the MAF wires was a simple. Since I have a Cali spec car, I had to deal with the swirl valve controller. All I did was get a long vacuum hose and stick the end into a hole in the intake piping (for constant vacuum). The air temp sensor was zip-tied.
Everything was setup and there was an 02 check engine light (this is not a problem because it also happened after the GReddy install). The code was reset and it never came back on. We took the car out for a spin (had to go to Walmart) and it felt good. The ODB-II software was hooked up to my car and we logged both ways. I boosted a few times on the first trip and the car picked up really well.
All in all, my car is now lighter (no washer fluid and extra intake piping) and getting colder air. If you have the time and patience, this is well worth the time.
I'll post pictures of the very ooglie ghetto SC CAI tonight... I'll also post the log files for the ODB-II trips (I know Alex wants them).

Phil and Drew have done it without taking out the washer fluid, but they didn't have to deal with the MAF tube (4th gen MAF tube integrated with charge piping).
I guess I'll have to wait until the IC setup to put the reservoir back. But I'm lighter.

COOL!!!!!!!!!
Nice job Kev!
I definitely think you're running much cooler air now. Too bad you didn't do an OBD-II scan before/after to see how much.
Also, I believe I've seen people relocate the resevior to the other side of the engine bay. Looks simple enough to mount it over by the battery(all that extra room now) and then just extend the feed tube. Looks like another red tube to add to the collection.
Anways, please post the files, since I'd like to see what I can find out from them. Did you reset the check engine light with the OBD software?

Thank you guys.
I have an OBD-II scan of my car before the CAI, but it was with me idling. Would you want that, Alex?
The relocation you're talking about is for the coolant. Stillen provides a coolant relocation bracket for their SC kits.
Yes, I reset the code with the software.

It can be used on all cars not just SC.

i remember a few months back seeing pics of a white 5th gen with the ninja kit with a cai like this. i think the pics are on my other computer, but i'll look anyway. I think he kept the windshield washer fluid hooked up, but i'm not sure

Colder air + 1 more psi =
Mr. 2 PSI should try this mod out.

Hmmm you may have stumbled on something my dear Dr. Watson. Show me the way Obie won.

But if the person left the fluid reservoir in the same location, then I would have to wonder...

Kev, do a us favor and trade your automagic in for a 5 spd or 6 spd(heh heh heh )
Don't forget to take out all the goodies before you trade!

Kev, so how much boost are you getting now? 12psi?
Also, when you cruising along, which means you are not boosting, then you suddenly slam on the gas, what's the boost level you get immediately? I asked this because when I do that, I surged up to 5psi. It takes awhile for the boost to build up to 7psi. Btw, the 3.125 pulley is on the way to me.

Boost level depends on what rpm I'm in. I can go into boost a little before 2k while cruising... If I'm on the freeway cruising, the car downshifts (2nd or 3rd) and I'm automagically in boost (no duh).
3.125? Good luck and don't blow anything...

Good job Kev, looks nice but a little ogglie.
But hey this is the prototype so its understandable.
Gesh you guys are bringing out the big dogs with 3.125 and lower pulleys, and me and my huge azz 3.60 pulley I think I need to start catching up.

Get your clutch first before you do the pulley... unless you want to practice on your stock clutch with the smaller midget.

True, I actually have the mueller flywheel at my house, the ACT clutch should be here today, and I also have my y-pipe, RT cat, turbo timer and 3.25 pulley,and a few other goodies, so hopefully I will be at 3 PSI soon If I have time this week I may install them.

I thought you were going to get rid of the car, nevermind the SC. Sorry, I don't check this forum out much, so I'm not up to date.

I have been a bit busy with the car. I got the SC on now with the 3.33 pulley, but will drop in the 3.125 pulley real soon. Everything is fine, except for the fact I still have the automagic. A 5spd swap is in the near future.
Btw, good decision on keeping the car.
