Since so many of you have asked, we are happy to oblige. The MS6 front mount intercooler kit is making a comeback! Before you get too excited though, there’s still a little bit of a wait before it’s actually being released. We wanted to let all of you Mazdaspeed6 owners know that we haven’t forgotten about you and we have taken our time to ensure this kit comes back better than ever before.
MS6 CorkSport FMIC fitment testing
As you can see, the 21”x10”x3” core is staying the same but we are improving the kit everywhere else. This means better fitment, more freedom for SRI selection, and the proven piping design philosophy used in the GEN2 Mazdaspeed 3 FMIC kit. While the MS6 was definitely not designed for an FMIC, the redesigned CorkSport kit makes it easy to say goodbye to the heat soak headache that is the stock TMIC.

We are still putting the finishing touches on the redesign, and obviously, have a few alignment issues to work out with another round of 3D prints. We can’t say for certain when this will be releasing, but the goal is late spring/early summer 2019. That being said, we will be sure to keep you updated as we inch closer to release.
While we’ve got your attention MS6 owners, are there any features that are a must have for you on this kit? Any other MS6 specific products you’d like to see? Let us know down in the comments (and I’m sorry but orange will not be a piping color option ☺).
Lastly, if you’d like to learn more about what to expect from the intercooler itself, check out the original release blog from way back in 2012 HERE.
Mazdaspeed 6 FMIC Comeback! July 11th, 2019CorkSport
We recently came across one of the original CorkSport EBCS prototypes which gave us a perfect opportunity to break it down and give you all an in-depth look. Read on as I go through what makes the CS EBCS tick, and more importantly how it gives you great boost control on your Mazdaspeed.
Just as a refresher before we dive in, an electronic boost control solenoid (EBCS) allows for precise boost control by using an electric solenoid to help control the wastegate. A boost reference travels to the EBCS where it can either push on the wastegate diaphragm or vent to the turbo inlet pipe. Where the air travels is controlled by the solenoid.
Obviously, the specifics change slightly depending on a number of factors with the turbocharger setup, but the concepts remain similar. Since the solenoid is electronic, it can be controlled within a tune. This means you are not wholly controlling your maximum boost with the spring in the wastegate and can hit boost targets larger than the “10psi” spring in your wastegate. For more information on boost control and the different EBCS setups, checkout Barett’s white paper on the subject.
Now the above image is a little different from the way you are usually seeing the CS EBCS. Not only is it missing the sweet black anodized finish (early prototype remember?), it needs some assembly before it can function properly. Below lists the components in the system and a short description of what they do. Obviously, we are missing a few key o-rings to keep everything nice and sealed, but all the important bits are there.
Manifold: This is the air distribution block. Air/boost comes in one port and leaves through a different port. Where the air goes is determined by the bullet valve.
Bullet Valve Assembly: More on this later, but essentially the center rod (piston) moves in and out while the black portion prevents air from reaching one of the manifold ports as needed.
Tension Spring: Keeps the bullet valve in the correct position when the system is not energized.
Coil Seat: Ensures the copper coil stays in place so the valve can operate properly.
Coil/Windings: Creates a magnetic field when energized that moves center rod of bullet valve.
Solenoid Body & Wiring: Contains the coil and other components. Also attaches the valve to the manifold.
Each one of the “thirds” of the bullet valve corresponds to one port on the EBCS manifold. They are labeled accordingly above. As EBCS is energized, the piston of the valve is pulled by the magnetic field created by the windings. There is a small amount of movement; only about 12 thousandths of an inch (0.012”) to be exact, which is enough to allow air to either reach the wastegate diaphragm or pass by into the turbo inlet pipe. Again this is simplified as it does not touch on duty cycle-the valve is typically rapidly opening and closing (seriously, check out the white paper).
The bullet valve is advanced technology that offers the utmost in fast responding fluid control. In addition, its profile offers the ability to make a pressure balanced valve and have a manifold that fits just about anywhere. All of this tech means you end up making boost faster, minimizing boost spikes, and keeping boost creep in check. If you want the bestin boost control for your Mazdaspeed, be sure to pick up a CorkSport EBCS.
An Inside Look at the CorkSport EBCS November 27th, 2018CorkSport
We all know the saying the 3rd time is the charm and this year’s SCCA National Championship Runoffs was no exception to the rule. The past 2 runoffs I have not made it to the finish line. In 2016 at Mid-O I was hit on the first lap and punctured my left front tire. At Indy, I retired as we developed a fault in the ECU from some beta software we were running and the car dropped into limp mode and I wasn’t able to maintain full throttle.
We have been working on the brakes for the past 3 years and during the season it limited us from running the car as much as we like. We have also been chasing a fault/error with the ECU/control system of the car. We were still able to get the car enough starts and race finishes to get qualified for the runoffs in Sonoma. Granted the car was not happy at most of those races and it was a struggle to get to the finish.
2 weeks before the runoffs we sorted out the ECU problem and were confident enough in the car to race it. The backup plan was to race my Spec Miata if we couldn’t get the Mazda 3fixed as I ran it this past season as well and had enough starts/races.
With the Runoffs at Sonoma, it was within 1-day driving distance unlike the past 3 runoffs at Daytona, Mid Ohio, and Indy so I got to try out the new (to me) truck and trailer.
I had raced at Sonoma one time prior, so the track wasn’t totally unknown like Mid-O and Indy, which all I had was simulator time so I was able to get up to speed quickly on a test day and find out what I needed to work on for chassis setup and driving. The driving was easy to adjust, look at the data, see where the driver was sucking, and had to man up to keep a foot to the floor in some sketchy corners.
The car, on the other hand, had what we call “a good problem to have”, too much power. We have been running a torsion-style differential in the car which works pretty well in a straight line and relatively flat tracks. Sonoma is not a flat track that unloads the car 3-4 times per lap. With the Mazda 3 and the amount of torque, it makes means I was unloading the tire enough for it to spin the inside tire. Most people think what is the big deal with a little tire wheel spin? It is a problem when you enter turn 10 at Sonoma at 97MPH and you start lighting off your right front tire. Look at the picture below and you can see that the front inside tires are barely on the ground and the rear isn’t. The speedometer would jump around and you could see the right front wheel speed turning at 5-10 mph more in the data.
We tried several suspension changes and driving style changes to make the best of it but in the end, we were way off the pace by 2-3 seconds of the rear-wheel drive cars in the class.
The good part about not being at the front of the field, there was zero stress when race day came.
Like any race there was a fun challenge, we would be heading into turn 2 blind as the race was at 4 pm in the afternoon and the sun would be shining directly down the hill. Since I wanted to see the end of the race I was a little cautious at the start and Ali in the other Mazda 3 got around me at the start.
We fought it out for 8 laps and he went into turn 6 too hot and I was able to get under him and pass him on the inside.
After a few laps I put a 4-5 second lead on Ali I was basically in no man’s land, slower than the front guys and faster than the back half of the field so I spent my time working on tire management (it is easy to overheat your left front tire at Sonoma) and made it to the end of the race.
My official finishing place was 10th but after some adventures in tech, I was moved to 9th in the final results. This isn’t where I wanted to be by any means but the 3rd time was the charm and I made it to the end of the race.
In this blog, we are going to SHOW a demonstration of exhaust gas scavenging. Instead of a lengthy blog full of text, we’ve opted to create a video that demonstrates the effects of exhaust gas scavenging for both good and bad designs.
We will be comparing the prototype CorkSport performance exhaust manifold, developed for the Mazdaspeed 3 and 6, to the OE exhaust manifold.
Exhaust gas scavenging within a manifold is the process of one cylinder runner, pulling (aka scavenging), the exhaust gas from an adjacent cylinder in a continual cycle. Now enough talk, to see an awesome example and an awful example of exhaust gas scavenging check out the video below. BONUS! Not only do you get to see what optimal scavenging looks like, but this is also the first sneak peek of the CorkSport Performance Exhaust Manifold…
We hope you found this as interesting as we did! Stay tuned as we continue developing the CorkSport Performance Exhaust Manifold for the Mazdaspeed platform.
It doesn’t take long for those building power to use up the stock Mazdaspeed K04 turbo. They are prone to fail, especially when you start shoving that extra air through it. A common question is, “My Mazdaspeed is smoking, is my turbo bad?”
First things first. There is a BIG difference between replacing a bad turbo and upgrading Mazdaspeed K04 to a more efficient one for more power. If you want to replace it, go with OEM and just plug and play, you’re good to go, wash your hands, and get on with your life. This will have your car up and running pretty quickly. However, your maximum power output will be limited and you will eventually have the same problem – the Mazdaspeed KO4 turbo will fail.
If you are saying to yourself, “It’s time to upgrade the K04 Turbo…I NEED more power in my life!” Then this blog is for you. Below, we lay out the basics needed to successfully install a CorkSport Mazdaspeed Turbo, highlighting the required supporting modifications to keep your Mazdaspeed safe. As a bonus, we keep our installation instructions on each of our product pages, so you can preview how easy the installation will be for your experience level.
Here it is, the list is comprised of the BARE essentials to run the 18G CorkSport turbo.
Giving you 50% more efficiency with your fueling system, as well as, a strong base to build power for your Mazdaspeed. The CorkSport Max Flow Fuel Pump Internals are built to directly replace your stock fuel pump internals and perform with immediate improvements.
The Cobb Accessport will give you the basis for tuning, and since this is required with the CorkSport turbo – you’ll want to make sure you have this in hand and ready for when you install your turbo.
These are the basic foundations of our Mazdaspeeds, without these two items you cannot operate your Mazda after installing an upgraded turbo. You will need your Mazdaspeed tuned, and your tuner is going to say the same thing.
That’s it, that’s all you need to run the CorkSport Mazdaspeed turbo safely. With this proper foundation, you can put yourself in a position for efficiency, or more power.
Now the question is do you want to make it go fast and harness the power that this turbo is built for? Keep reading and we’ll provide some other awesome upgrades that are the next step once you have your turbo installed and running. Oh, and if you are looking for a proven path to make 400WHP, check out our Chasing 400 WHP Blog here!
The CorkSport turbo is rated for up to 450WHP with the right set up. Unless you are going for the MOON and shooting for over 700WHP a 3.5” intake will be more than sufficient for this turbo. Giving you some extra airflow to increase your power range, and harness what your Mazdaspeed3 is capable of. Note: Will require additional tuning!
Doesn’t matter if you go with a high-flow catalyst or opt-in for one without, the choice is yours. However, if you want to utilize its flow you are going to have to upgrade to a bigger diameter. Our 80mm one does really well, plus it sounds GREAT. Note: Will require additional tuning!
It’s no secret that car engines are just big air pumps, the faster you can shove air into the engine and how fast you can expel it efficiently is what it takes to make more power. No need to run the stock 63.5mm exhaust when you can run our 80mm (like to wake up the neighbors every morning, go with our non-resonated, you can’t beat the cold start)
If your power goal is 450whp or less you can get away with just upgrading your TMIC and be on your way and they look great in your engine bay. Note: Will require additional tuning!
If you have the 2nd gen you can really utilize that hood scoop from the factory. Not only that but you can even see a noticeable performance gain with our larger hood scoop and a TMIC set up.
When it comes to your Mazdaspeed we know you want to create safe power and harness the true potential of your ride. Be sure to build upon the proper foundation and head in the right direction for your build. Our techs are available for any questions you have and are ready to assist with planning your Mazdaspeed build path!
