CRAZY RED ITALIAN’S
RACING BEAT COLD AIR INTAKE SYSTEM

-----------------------

WHAT IS THIS THING?
The Racing Beat Cold Air Intake (CAI) system as offered by Crazy Red Italian is an affordable performance modification for the Mazda Miata. The package comes in two versions, one for 1.6liter ’90-’93 Miatas, and one for 1.8 liter ’94-’97 models. It works with cruise control but is incompatible with strut tower braces. The CAI replaces the stock air filter and airbox — the large
black plastic box behind the driver’s side headlight — and the air intake snorkel which comes off of the airbox.

There are several reasons to get a CAI system for your car. When your car is running, it needs three things to make it “GO”: Air, Fuel, and Fire. The CAI system improves oxygen-rich cool airflow to the engine thereby making the ‘breathing’ better, and the whole combustion process more efficient.

The result? Better performance. This performance increase manifests itself in more low-end torque, more power for passing & downshifts, and a nice swooshing sound that comes from under the hood during acceleration.

The package is inexpensive (under $200) and gives lots of ‘bang for the buck’. Installation is fairly easy, requires no permanant modification to your car, and can be completed with basic tools. Besides all that, it looks great in your car.

David DeNuzzo (“Crazy Red”) and Frank DeNuzzo (“Crazy Pa”) worked very hard with me to try and get the kit to me before I went on vacation. While it didn’t arrive in time, their help was greatly appreciated. I’ve ordered several things from Crazy Red, and each time have been impressed with their willingness to go the extra mile for me.

INSTALLING
This is a fairly simple installation if you do not have cruise control (I don’t have cruise control). If you have cruise control, it adds a couple of steps and some more time to the install, but it is still quite managable. It is a completely ‘reversable’ installation — there is no drilling, cutting, or other permanant modification of any part of the
vehicle. The entire installtion process took me about an hour, and that included stopping several times to double-check the instructions and clean up a little bit. If I had to do it again, I could probably do it in about 30-40 minutes.

The first thing to do is to read the instructions that are included — read them twice. Nothing in there is very difficult, but it’s good to read and have some idea of what you’re doing before you approach the car.

Next collect your tools. You will not need anything special; just 10 & 12mm sockets, a socket wrench, small flat-head screwdriver, phillips-head screwdriver, a couple of towels for cleaning the engine compartment and setting parts on, 10 & 12mm closed-end wrenches, and (probably most important) extenders for your socket set. Extenders of 4″ and 8″ are almost mandatory for the install.

Gather the kit, your tools, some towels, and an empty box (for the parts you remove) and head out to the car.

Broadly speaking, the installation process is this:

  • Familiarize yourself with the engine compartment (5 minutes)
  • Remove wires that cross over the airbox. (5 minutes)
  • Remove the airbox and airflow meter assembly from the car (20 minutes)
  • Remove the airbox from the airflow meter (5 minutes)
  • Install the CAI onto the airflow meter (5 minutes)
  • Install CAI into the car (15 minutes)
  • Reattach necessary wires (5 minutes)

The instructions suggest disconnecting the battery, but I decided to live dangerously and leave it connected. No problem there as long as you’re careful.

First, open the hood of the car and take a peek into the engine. The area where the work will be done is just behind the driver’s side headlight. I suggest following the diagram in the instructions and locating and inspecting all the mentioned parts.

You begin by removing the wiring that is around the stock airbox (airbag wiring, airflow meter cabling, etc.). The stock air intake snorkel is loosened, the air tube removed from the other side of the airbox, and the airbox/airflow meter assembly is unbolted from the car.

Once it has been unbolted and examined (to make sure it will come out cleanly), the airbox/airflow meter/snorkel assembly can be removed. This is a slightly tricky part — you’ve got to use both hands and it’s somewhat awkward.

Examine the gaping hole left in the engine compartment, and clean up a few loose bolts, plates, and other remnants from the previous air system before proceeding.

You can then go sit down for the next step. Remove the airbox from the airflow meter and attach the airflow meter to the aluminum elbow. The K&N Filter is attached, the braces configured and attached, and then it’s back to the car to install the new assembly into the car. There is one step in the process when you’re installing nuts onto two bolts that you cannot see. This is the trickiest part of the installation, but it’s not bad even if you drop the nuts (like I did).

Wiring is replaced, everything is checked and tightened down, and then the hood can be carefully lowered. Reattach the battery (if you disconnected it) and you’re ready to go.

POST-INSTALLATION
Take a look at the engine — notice how nice the unit looks in the compartment. Now fire it up. Be a little disappointed because you won’t hear anything different while the engine idles in your garage.

However, take the car out for a drive and you’ll immediately see that the car exhibits a noticeable increase in power between 3,000 RPM and redline. The engine seems to move more evenly between the gears. Intake growl is present beyond 3,500 RPM and the exhaust note is a bit louder
and deeper too, however I don’t mind one bit. The sound gets you on every shift — the car sounds more aggressive and sporty. It makes me smile every time I press down on the pedal! Throttle response is improved, and some people report a 7-8 HP gain and that torque is noticably improved. I have not yet filled up my car to check the impact (if any) on milage.

OVERALL
This is a nice-looking, inexpensive, easily-installed performance modification for the Miata. I would recommend it highly for those Miata owners who want to beef up the performance of their car for a reasonable price.

The Waiting Game…

Well, now it’s just waiting…

I’ve put in change orders on my DNS to point from my old host to my home-host, but it takes some times, sometimes a couple, two-three days, for the DNS to propogate.

I will keep you posted as to when that change has happened.

There should be little to no downtime for DrewVogel.COM; however, some quirks will likely need to be worked out before the system is running smoothly.

Thanks for bearing with me.

Another system upgrade, this one easier…

Another system upgrade caused me to reboot the system today, after 12+ days of uptime.

I upgraded the Apache server, the kernel (the core of the operating system), the mail handler and assorted tools, the mail reader, some modules for the new Apache, and a few security fixes to some other files.

THIS time, I remembered to adjust my LILO links before I rebooted, so it was a very painless process.

In addition to the upgrades indicated above, I also switch some hard drive settings that nearly doubled the speed of the hard drives. Users should notice a speed increase when using the system, since drive time has, effectively, been taken out of the equasion.

As always, if you notice anything unusual while you’re using the system, please let me know.

UPDATE 05-Dec-2001: Updated to 1.2.4 of the Photo Gallery software we use.

OTR Concert at Taft Theatre, December 8, 2001

I like the Green Yellow Swallowtail song more and more. At the
SouthGate House show (in September) it seemed very eerie because they
had cut their backroads tour short within a week or two because Karin’s
mother had a stroke. The line something like “mother’s not dead she is
only sleeping” hit hard. Now the line seems softened but still has more
power now than its first performances. Karin said it started as a song
about Linford’s mother and became a song about Karin’s mother.

I also liked the “will it make a difference when I go” very much.
The old songs with a rock edge and the newer songs with a blues edge are
a fine complement to their overall mix of song choices. For a couple
songs all the warmup musicians plus Kim Taylor joined together. The
extra songs by Jack Henderson were a special treat.

I love Buddy and Julie Miller. The last time I saw them at
SouthGate House Buddy was wearing an over-the-rhine patience t-shirt
with a windup alarm clock at 9:30. It was a special treat to see them
with Over The Rhine instead of by themselves.

I missed the opener. Friday night Christmas shows make it
difficult to first adjust to getting off work and then getting to the
theater and finding parking. I was there at 8:00 and the first act was
already over. I saw all of Buddy & Julie Miller. The sound system did
not seem to be adjusted well for them and seemed too loud to me. The
sound system seemed adjusted for over-the-rhine as far as I could tell.
Someone else told me that they detected a buzz in the sound system.
Over-the-Rhine went on at 9pm and played to about 10:50 including
encores. The security people were quick to push people out of the
auditorium–maybe that is why noone posted a set list. During the show
one security person on each side of the stage was seated on chairs
facing the audience.

The show seemed too short to me but I never measured how long their
normal show lasts. An hour and 50 minutes sounds like a normal length
for a concert. There was some talking with the audience but it somehow
seemed less than usual except for the part about asking who travelled
the furthest. California or Oregon seemed to be the winner, then a man
yelled “Hawaii”. Karin did not seem to believe him. He yelled out
that he had his drivers licence (I guess to prove that he really was
from Hawaii).

Some people told me that after the show they were going to meet at
Kaldi’s. I went with the Uno’s crowd. There were 38 people in a
private room as far in the back as you can get in Uno’s. At one point
everyone stood up and said their name and where they came from, even
people who were not on the list but came as guests of people on the
list. A very large amount of respect when Don Smith said his name. I
believe he was one of three people who started this email list. Three
people even showed their tatoos: one on the right back shoulder, a
Christian fish on the top of a right foot, and a large new tattoo on the
left shoulder of David Armstrong.

The post concert brunch at Drew Vogel’s today was well attended.
Good food and coffee. Drew even arranged to have three acts of live acoustic music in his basement:

1) Ryan Adcock
2) Rick Callender (Bink who wears a kilt to each OtR Christmas concert)
3) Ashley Peacock

What a weekend!

What a great weekend we had here in Cincinnati!

This was the weekend of the annual Over The Rhine Christmas show at the Taft Theatre, and there were many festivities that went along with the show.

There are Reviews of the show in Reviews and pictures in the Photo Gallery. Check them out!

Every December, the music fans in Cincinnati get a very special treat. Cincinnati-based Over The Rhine present their Christmas concert at the Taft Theatre.

This year’s show featured two guest acts. Erin McKeown and Buddy & Julie Miller were openers. Over The Rhine played for about 115 minutes, including encores.

After the show, a group of Over The Rhine fans (many of whom flew in from around the country to attend this show) went to Pizzaria Uno’s for a late-night dinner and much merriment.

On Saturday morning, I hosted an informal Brunch at our new house, complete with excellent food and live music.

The whole weekend was a great time.
