Enhancing the Performance of the Mazdaspeed Protege

Wed, 11 Jan 2012 05:04:20 GMT

The Mazdaspeed Protege has a lot of performance potential. The drive train in stock form is adequate, but is restricted by it's surroundings. Here are a few enhancements that will help the Mazdaspeed Protege perform better (please note that your dealer warranty coverage may be affected if you enhance your car):

1. K&N Air Filter or Cold Air Intake (CAI)
The stock air box sufficiently supplies cool air to the engine. When using the stock air box, install a K&N drop in air filter. You can also use some hose (from a hardware store) that extends to the front of the car for a "ram air" like intake. This new hose will take the place of the stock elbow at the end of the air box. If the stock air box is not cool enough for you, try an aftermarket cold air induction system. If you prefer to use an cold air induction system, make sure it is routed so that the filter cone is in the best location to get cold air. There is not that much room under the hood, so fabricating a shield to protect the filter cone from the hot engine is a good idea.

2. Turbo-Back Exhaust
The stock exhaust on the Mazdaspeed Protege is quite restrictive. It is somewhat small in diameter, has two catalytic converters (one positioned right after the turbo), and the muffler. The best setup would be a nicely flowing 2.5" diameter pipe with one performance catalytic converter (or no converter if you desire) and a performance muffler. There are plenty of exhaust kits available for the Protege in both 2.5" and 3" diameters.

3. Larger Intercooler
The stock intercooler is quite small and poorly constructed. Luckily, there are plenty of intercoolers available for the Mazdaspeed Protege. Upgrading to a large intercooler will help keep the turbo cool and increase cold air into the engine, making more power. While upgrading the intercooler, it is also recommended that the hoses are replaced. The stock plastic piping can get hot and are prone to leaking. Get a nice aluminum piping kit along with your new intercooler and you will be happy.

4. Increasing Boost
The stock boost is set at about 6psi. This is adequate for the car in stock form, but too low after performance enhancements are made. Only after you have freed up the exhaust and added a larger intercooler, should you consider increasing the boost. Increasing to around 9psi should grant sufficient power gains and still be fairly safe. There are both mechanical and electronic boost controllers available. You can also purchase computer modules that piggy back on your stock ECU. It would also be a good idea to get a boost gauge installed!

Winter Driving in a Mazdaspeed

Wed, 11 Jan 2012 03:26:10 GMT

Anyone who has driven a Mazdaspeed in the snow knows that it can be a hazardous experience. The stock Potenza performance tires are sticky on dry pavement, but in the snow they get little if any traction. This is due to the lack of sidewall, tread and tread depth on the performance tires. The tires need an aggressive tread pattern with plenty of sipes to grip the snow. The stock tires are great for dry conditions, allowing for a greater patch of rubber to grab the pavement, but are extremely dangerous for winter conditions. The stock tires are NOT all season tires!

Do not get stuck in the snow or risk having an accident. Please do yourself a favor and get snow tires or drive a different vehicle (if possible) during snow days. The Mazdaspeed vehicles actually handle pretty good in the snow with a set of snow tires, partly due to it's limited slip differential. Some Mazdaspeed owners have purchased a cheap set of rims and snow tires for the winter. Others have the luxury of having a second car to drive on snow days and garage their "baby" for the winter. Still others replace their performance tires and mount all season performance tires on their rims.

The stock tires can handle clean winter roads, but when the snow flies, do yourself a favor and get a set of snow tires!

FWD Handling: Benefits and Characteristics

Wed, 11 Jan 2012 02:56:08 GMT

Benefits of FWD

There are many reasons listed for why the OEM companies are using FWD. They include costs, size, assembly, interchangeability, etc., which may be considered but certainly aren't the main cause. Looking at just the pieces involved in the drive train will lead to the answer. The FWD cars don't have a 5 foot long driveshaft and have a 12-18 inch shorter transmission (i.e., output shaft). Both pieces rotate with the engine. Drag racers learned years ago that lighter rotating pieces (in the engine or the transmission) make the car go faster at the track. It isn't found on the dyno but can be easily proven in the car at the track. Having no driveshaft and only half the transmission shaft saves 15-20 pounds of rotating weight. Drag racers spend thousands of dollars to get 5 pounds out of the rotating mass of the engine.

A related consideration that may be more important in handling is unsprung weight. The 5 ft. driveshaft was unsprung weight. All FWD cars use an independent suspension while 99 percent of the RWD cars (front engine) use a solid axle. Weigh the solid axle and realize that it's all unsprung weight. We think that every handling "expert" knows that less unsprung weight help handling!

FWD Handling Characteristics

A vehicle's handling characteristics are not always the same. A FWD car at extremely low speed will tend to understeer. Strangely enough, a front-engine RWD car understeers at low speed also. Both are caused by the front weight bias. At higher speeds, typical of minimum speeds at a road race track, the springs and sway bars come into play and the car reverts to its designed characteristics. In production cars, the design choice is slightly understeering.

It is obvious that the FWD cars use the front tires for acceleration, braking and cornering. This demands a lot of the tire. However, in two cars, one FWD, one RWD, both in the same class, the FWD car is somewhat faster in lap times but it uses up the tires faster.

In summary we think that the examples listed above show what's going on in racing and why the FWD cars are so popular. The at-the-track evidence shows that the FWD cars do go faster and handle better even though they work the tires very hard. They may not make the greatest drag cars but we're talking handling and road racing and that seems to be where the FWD cars do best. They also seem to handle better in traffic which makes close racing easier. The at-the-track evidence speaks for itself.

Mazdaspeed Protege Alarm Sensitivity

Wed, 24 Aug 2011 04:22:48 GMT

Anyone who has purchased a MazdaSpeed Protege knows that the alarm can be VERY sensitive when brought home from the dealer. Loud motorcycles or that neighborhood stray cat may set the alarm off at all hours of the night. This can be quite an annoying occurrence!

This situation is easily corrected, however, by adjusting the alarm sensitivity on the vehicle. To adjust the sensitivity, look under the drivers side dash-board. You will see a black alarm box with a small white adjustment knob. Turn this knob to adjust the sensitivity to your liking!

Mazdaspeed Protege Kenwood Stereo Blackout

Wed, 24 Aug 2011 04:21:35 GMT

This is a rare occurrence, but does happen. The Kenwood stereo in the MazdaSpeed Protege stops functioning for no reason. There is obviously a bug in the stereo's computer system. The screen on the display will go black or have red lines or dots. Music will still play for a brief period before all goes dead. The radio will then tilt 90 degrees so you can remove the face.

The stereo can be brought back to life, however, by simply pressing the reset button on the front of the stereo face. The reset button is a little white button to the left of the SRC button. You can depress the button with a pin, paperclip or pen head. The only problem is that all presets will be lost and you will have to reprogram the radio to your liking.

Hopefully Kenwood can determine the cause of this little bug, but for now it's just one of the quirks of owning a MazdaSpeed Protege.

Burning MP3s for the Mazdaspeed Protege

Wed, 24 Aug 2011 04:16:08 GMT

Burning MP3s for the MazdaSpeed Protege is a new and fun adventure. Because MP3 files are so compact, you can put a ton of music on one CD. While burning CDs for the car, however, I found that I wanted to burn whole albums in their correct order. With the software that's available, this still is not an easy task.

The best way I found to do this is by adding numbers (starting with 01) to the front of each album and track. The program that was the easiest for me was Roxio. Using Roxio Classic, I numbered the albums and tracks and burned my CD. Time consuming, but worth it. The albums and tracks are burned in the exact order that you specify.

Once in the car, the Kenwood system performs perfectly. All the songs are played in order and the numbers do not show up on the scrolling text (I assume it's displaying the file description and not the file name). You can cycle through albums using the AM/FM keys and select tracks using the arrow keys. Listening to MP3s in the car makes me want to drive around all day!

Rules of the Road

Wed, 15 Jun 2011 04:31:47 GMT

THE CAR IS UP-TO-SPEED
BUT ARE YOU?
Rules of the Road for
New MAZDASPEED Protege Drivers:

1. ALWAYS use premium unleaded fuel. Your high-revving turbocharged engine requires the best
fuel available. Avoid fuel additives.

2. ALWAYS allow your turbocharger time to "cool down" by idling the engine for 30 seconds after
driving at freeway speeds, up long hills or for extended periods.

3. NEVER race your engine when starting it. This can actually damage the engine.

4. NEVER take your MAZDASPEED to an automatic car wash. Some automatic car washes can
damage the finish on your alloy wheels. Instead, wash your MAZDASPEED
at least once a month with lukewarm or cold water to protect the finish and
keep its appearance clean and bright.

5. REMEMBER you've got a limited-slip differential up front that's designed to work with
tires that are the same size. So, whenever possible, avoid mounting your
smaller, temporary spare tire on the front axle.

6. ALSO REMEMBER to protect your MAZDASPEED's special body parts (front fascia, side
skirts and rear chin spoiler) from damage by driving slowly over driveways,
dips, speed bumps and the like.
