Product Release!!! CorkSport 4 Piston Big Brake Caliper Kit for Mazdaspeed

After a long wait and a lot of testing, we are proud to announce the availability of the CorkSport 4 Piston Big Brake Caliper Kit for the 2007 and up Mazdaspeed 3. With almost 300hp stock, the Mazdaspeed 3 can easily outrun and outperform its stock single-piston calipers, this is amplified when more power is added. With the CorkSport big caliper, you can count on a better braking feel and a more balanced setup to give you the confidence you need to use all those horses you paid for.

Crafted from extremely lightweight billet aluminum, the CorkSport calipers use an opposed-piston design that is fixed to provide significantly improved pad wear, and caliper rigidity over the OEM design. At just over 7 lbs, the aluminum CorkSport Mazdaspeed Big Brake Kit shaves almost 8 lbs of unsprung weight off each corner of your Mazdaspeed, adding more stopping power and a much better pedal feel. Available in 3 anodized colors, this brake system has everything you need to easily upgrade your stock braking system and includes high-strength steel brackets, calipers, stainless steel braided front brake lines, brake pads, and the all necessary hardware.

Product Release!! CorkSport Mazdaspeed 3/Mazda 3 Race Rear Motor Mount

We are happy to announce the new CorkSport Race Rear Motor Mount.  Why the Race name?  We wanted to offer the best part for our customers looking to run a premium mount without the premium price.  CNC machined from billet aluminum and hard anodized black with the stylish CorkSport logo this mount is the new leader in quality and design.

Mazda 3 performance rear motor mount

Designed as a direct replacement of the OEM motor mount, the CorkSport Race Rear Motor Mount provides improved handling and shifting by replacing your factory mount and rubber bushings with an upgraded mount and urethane thrust surface for added stiffness and improved driver responsiveness.   This provides the added stiffness you desire while maintaining the comfortable ride you want and reducing the effect of NVH (noise, vibration and harshness) in your cabin.

Bolt in design rear engine mount for the 2004-2013 Mazda 3 and the 2007-2013 Mazdaspeed 3

With the new Race mount you don’t have to choose comfort over performance or buy extra mounts to have a 95 durometer rear motor mount in your garage, you get hardcore all the time!

The Mazdaspeed 3/Mazda 3 Race Rear Motor Mount is Black Anodized with Zinc Coated Sleeves for a durable, long lasting life.

Grams Per Second Explained

At CorkSport we’ve had a lot of questions over the years about mass airflow (MAF) signals. Including some great discussions about a pesky measurement called grams per second (g/s) and what that really means. There is a lot of interesting misinformation out there that we have heard and wanted to take the time to explain how grams per second actually work and what it really translates to. To understand what grams per second really is, we will first discuss where the reading comes from.

CorkSport Mazda SkyActive Short Ram Intake CX5 Mazda 6

When you are logging a MAF signal you have a few options. One is MAF voltage and one is MAF signal. They are really the same thing, just expressed in different ways. The MAF sensor itself is a 5-volt system that gets a signal from the air traveling in the MAF housing. A typical MAF sensor uses a wire or film that is heated electrically. The incoming air cools the element to which the sensor has to regulate; this regulation lets the ECU know how much air is going through the engine. This voltage is then converted in a table stored in the ECU (Engine Control Unit) and this is where you get your g/s reading.

Now for the fun part: when you purchase an aftermarket short ram intake the MAF housing shape and diameter determine the voltage reading and thus the g/s reading. If the housing has been engineered correctly then the reading should be fairly close to the factory reading. Often the factory runs cars on the rich side for fueling when they are in open loop. The sizing of the MAF can be adjusted to create more power at the top of the rev range by leaning out the air/fuel mixture. The MAF signal also is a major part of calculating load values which control timing and most other functions of the engine. This is not a part that should be taken lightly or changed indiscriminately. In our extensive testing we have found that even half a millimeter in diameter of a MAF can cause measureable differences.

The g/s reading can also be used to check power-increasing mods such as exhaust or intercoolers. If you log power runs you can see the g/s increase with different mods. Although, be careful when comparing data on the same car. If you aren’t testing on the same day or conditions you can see slight differences because of air density or other environmental conditions. Unfortunately, when you want to compare different intakes you will not be able to show an apples-to-apples comparison. Because the MAF housings are not the same sizes between brands the signal will be different. If you check a MAF housing that is larger than stock you will read less g/s and one that is smaller you will read more g/s. Simply put, when comparing different intakes or any other factors that are different: Grams per Second does not equal power.

 

CorkSport MAF Housing

With all the complications in making a MAF to perform exactly how you want, we chose a one-piece fully machined aluminum MAF housing. This way you can precisely control quality and sizing. Then by creating an air straightener that is injection molded, we can have the most control over our MAF signals. There can often be issues with purchasing lesser quality MAFs housings that are welded together or bolted to pipes. Not only can you have leaks but you cannot preserve the shape perfectly. Look for more intake articles and an explanation of what a big MAF intake is and when you actually need one soon.

Why Durometer Doesn’t Matter

What is durometer and what does it mean? If you know what it is, when does it actually matter? Every day at CorkSport we are asked this question. Many times, we are told that many of you assume that the higher the durometer or something attached to a car, the more noise and vibration will be transmitted into the passenger compartment. This however, is not always the case.

CorkSport Mazdaspeed 3 Race Rear motor mount

 

Durometer is the measure of the hardness of a material. The higher the number, the harder the material is. When talking about rubber or polyurethane, you will often hear durometer numbers between 60a and 90a. There are several scales for the measurement of durometer, in the case of bushings, you will almost always hear about the Shore A scale. The letter at the end of the rating will tell you which scale you are rating.

When designing engine mounts or suspension pieces, the durometer can be very important, but the shape and how the piece is used can be even more important. The overall durometer number will give you the first idea of how much vibration the mount or bushing might transmit, but this can easily feel different depending on the surface area used.

If you have an engine mount that has to fit a certain area and you decide to design it with a very small bushing, or a bushing that has to do more than just isolate the two parts, you can end up transmitting a lot more vibration. If you compare a 1” diameter bushing and a 2” diameter bushing you don’t end up with double the amount of surface area, you actually increase the surface area by 4 times! That isn’t the only way bushings work though. Depending on the direction of the force, you could use a bushing much smaller and obtain a much better isolation than one with a bigger available surface area subjected to more force. In many cases, only the durometer of the bushing is taken into consideration when many mounts are designed; not how the bushing is used, its size or the forces applied to it.

CorkSport Passenger Side Motor Mount

Recently I was asked by Kevin Pugh (the owner of MazdaSpeed Forum) the durometer of a mount we released. I replied to him; “it doesn’t really matter, but I will tell you anyway”. We had a good laugh and talked about many of these points; and because of that conversation this blog post was born. Much like many of the topics on the CorkSport blog, we recognize the market and what is important to you. This information is as important to you as it is to us, and whether you buy our entire catalog or just read our blog and stay stock, we always want to be of service to the Mazda community that we have been dedicated to since 1998.

Cheers,

Joel
