The Coldside now lives with Dan at
Run-Down.com
Updated - 3/16/05.
The cold air isolator box has been finished and installed. This page was starting to get a little
out of hand with the amount of photos, so I made a seperate page for the Cold Air Box. You can
also zip down to the bottom to see a single pic.
2/24/05 - The NACA duct has been installed in the coldside headlight lid. Go to the bottom to see it, or follow
this link.
It takes either a very brave or a very stupid man to cut up an expensive, Carbon Fiber (capitalized) Monstarflow
intake to fit on his BR Performance Coldside supercharger. Well, I am that man! And I have the dead Dremel cutting wheels
to prove it. CF sure is hard to cut...
Just like my infamous N/A intake, I'm sure this one will evolve in time. This page will have the most current
revisions at the bottom with a little update notification at the top. Keep checking back. And if you'd like to
talk about it, feel free to email me.
My original supercharger intake.
The intake that came with the Coldside wasn't really my bag, baby. It put the filter back on the
hotside, near the header. I made this lovely contraption out of the parts shipped. It worked, but it sucked
air right next to the hot blower housing. This in turn made the housing hotter, which, in turn, made the intake
charge hotter. Even on a cool October evening, the blower would be burning hot to the touch after a cruise.
Something had to be done.
Max boost seen with this intake at 5000 feet: 7 psi on a 35 degree morning.
Average max boost: 6 psi.
This was once an NB Monsterflow intake.
I was certain I could make the Monsterflow tube work, so out came the Dremel. Not only does this intake look
much nicer, but it works much better. With the headlights raised, I can see the air filter from outside
the car. Some decent cold air is getting to the filter. This was immediately obvious the first time I put my
hand on the blower (by accident) after a testdrive. It was warm, but not burning.
Max boost seen with this intake at 5000 feet: 8.5 psi on a 40 degree afternoon.
Average max boost: 7 psi.
The air filter angles down where the rad. overflow bottle used to live.
Here, you can see some of the work I did to the Monsterflow. Really, I only made three cuts, and if I had measured
the elbow correctly the first time, I would have only made two cuts. The "front" 10" was reused as you see here.
It had to be rotated to point 180º from the stock angle, but since I was putting the MAF in the middle
of the pipe, that wasn't a hard order at all.
90º silicon elbow + 90º carbon fiber elbow.
The 2.75" blue silicon elbow came from injenonline.com.
I was hoping for black, but for $12, I was happy to order the blue one. The cheapest I had found elsewhere was
$50 for a 3" elbow, which wouldn't have fit well anyway. The c/f elbow fits in this and has some room to slide
in and out for optimal intake placement. There's just enough space for the tube between the choo-choo (Coldside bypass)
and my TEIN shock bolt seen in the foreground. Some folks may have noticed the charcoal cannister is also missing. It'll
be relocated to the "hotside" someday.
Current March 2005 engine bay shot from the hotside.
The tiny radiator bottle is from a 99-00 Civic. I bought it without previously finding a place to put it. There's a few
other options, but this one seemed the best. The TrackDog
header blanket keeps that side of the bay so cool, I feel pretty safe putting the bottle there. I also installed my
evaporative charcoal cannister there in the empty space, making the rad bottle look not quite so out of place.
It's much nicer with the evap hooked up again; I had bridged the tank vent and the fender dump line so
that all of the gas fumes vented to the fender. Also, if you look closely, you'll
also notice my re-worked wiring harnesses. They were getting a little out of hand after the Coldside install. An hour
of work with some wire loom and zipties cleaned them up to "unnoticable" levels.

The carbon fiber Coldside NACA duct.
The crappy winter weather didn't keep me down for long. I bundled up, warmed up the garage, and got out the dremel.
My persistance was rewarded by the duct you see above. I even took some pix and wrote up a page detailing
the scary headlight lid cutting process.
The NACA duct points the air in the right direction and the Coldside sucks it in.
Now I just need to finalize my isolator box. Those that have been here before might remember my N/A intake complete
with NACA duct and isolator box.
Ya think that air is cold enough?
A freak snowstorm hit Albuquerque in March, 2005. I was driving home at the time. I saw this little snowdrift in
the engine bay and immediately ran to get the camera. Maybe this will finally silence the folks who say the
NACA duct doesn't work for induction... By the way, the lights were down for most of the drive. I raised them
when I parked to clean out any ice that might have grabbed hold.
This gives new meaning to the term "Coldside".
No problems from the extreme-cold-air induction. I just wiped the engine dry after parking. However,
the moisture around the fuse box and sensitive EGR boost sensor did worry me a little, so I finally
finished my intake isolator box.

Cold air for the Coldside.
March 2005 - The latest revision to my Coldside intake. The intake isolator box was made out of
ABS plastic sheeting (1/4" thick) instead of aluminum. There's some pretty delicate things nearby like
that S/C bypass actuator that I didn't want getting eaten up by aluminum. I spent much time getting the fit
as exact as possible. The design and placement allowed me to get a tight fit without actually bolting the
shield down. It's held in by pressure and removes as a single unit for easy servicing. For more details, check
out the Coldside intake isolator page.
