The Wait Is Over: The CorkSport Performance Intake Manifold Is Here

Can you believe we started this project back in 2012?

Yes, it’s been a long journey, and a few too many “two weeks”, only to find that more improvements were needed. We’ll be frank, this has been a challenging project to tackle, but we have prevailed. We have pushed past the challenges faced in manufacturing the complex design, and are proud to announce that we are ready to present you with the most complete solution for the Mazdaspeed 3 and Mazdaspeed 6 platform.

The CorkSport Intake Manifold is here for those of us wanting some more flow in our lives.

Our design focuses on performance without sacrificing OEM fitment or drivability. With equal flowing runners, higher flow than OE, and TMIC fitment, it truly is a complete solution to the OE intake manifold.

Fitment is huge when it comes down to large engine components like intake manifolds. While designing the CorkSport IM, we wanted to retain as many OE features and mounting locations as possible while maintaining neat and tidy packaging. By doing so, we were able to keep components such as the TMIC, OEM throttle body, MAP Sensor, and even the oil dipstick bracket in OE locations. This all means a relatively quick and easy part to install, but we made it even easier by clearing some space around hard-to-reach areas.

The CorkSport Intake Manifold may fit like OE, but that’s where the similarities end.

The CorkSport Mazdaspeed Intake Manifold is designed with performance and drive-ability in mind, with the larger plenum design and long cylinder runners. Since the intake plenum is about three times larger than OE, there is an increase in high RPM power capacity without sacrificing throttle response and drivability. By maintaining the length of the cylinder runners (vs the typical aftermarket intake manifold), we improved mid-range power while still having peak RPM capacity with the single runner design vs. an OE split runner design.

The increase in performance also comes with an increase in engine health.

By optimizing the design for equal flow between runners, the CorkSport IM eliminates the flow imbalance of the OE intake manifold. This significant imbalance causes cylinders to run excessively lean or rich, affecting engine durability and performance. Check out the graph below to see the difference. Not only does the CorkSport Intake Manifold outflow the OE design by 70CFM per runner on average, but also significantly reduces the flow imbalance to 2% or less vs the OE imbalance of 21%.

This means your engine can run stronger, longer, and have a higher potential to make power.

But enough talk about numbers and flow, let’s SEE some numbers. The dyno graph below shows the difference before and after the CS IM on a Mazdaspeed3 with a CorkSport TD05H-18G turbo equipped. Not only was there an increase in power and torque across the entire RPM range, the turbo spooled around 100RPM faster than with the OE intake manifold.

But wait there’s more! Along with the overall design improvement over OE; there are additional design features that you need to know about.

  • Firstly, we increased the size of the throttle body opening. This allows the OE throttle body to work great but also allows for a larger throttle body to be installed without modification.
  • Next there are added fueling ports for each runner. They are standard 1/8-27 NPT ports that can be used with methanol nozzles or other fueling options.
  • Finally there is an extra 1/8-27 NPT port that can be used for boost controllers, gauges, or the like.

Now you may be thinking, “But there aren’t any larger throttle bodies available.” To that we say, “Not just YET!”

Along with the great features of this new Performance Intake Manifold, we are also providing nearly all of the hardware you need for installation; that is, the brass fittings that come pre-installed on the intake manifold and the additional hardware and hoses needed for auxiliary components.

Now we would like to circle back to where we started with this conversation:

We here at CorkSport pride ourselves in doing everything in our power to provide you, our customers, with the best possible products out there. We also are committed to being real with you guy as well, because we too are Mazda-lovers who get a thrill out of overcoming the toughest challenges that stand between us and the ultimate car experience.

The most challenging aspect of this project has been getting the manufacturing to an acceptable quality, and consistent among each intake manifold. We have tested the intake manifold on multiple cars in-house and with various beta testers, the results speak for themselves: this is an exceptional performance product that your Mazdaspeed will love to have.

Believe us when we say that this design is tough to manufacture,  and that process results in no two parts being exactly the same visually; but it also means that each manifold has its own unique look and character, the same way our cars do.

We guarantee that the CorkSport Intake Manifold will give you the best performance out there, but if for whatever reason you’re not satisfied with the unique look of your IM, please contact us and we’ll be more than happy to take care of you like we always do. – We’ve got your back!

That being said, if you’re looking to take your Mazdaspeed to the next level in both speed and reliability, the CorkSport Intake Manifold is the best comprehensive solution on the market.

These babies are only available while supplies last, so don’t wait, they’ll be gone before you know it!

4 inch Intake and a Clean Engine Bay? The CorkSport 51R Battery Box & ECU Relocation is NO Compromise

CorkSport is proud to announce the new ECU Relocation Battery Box designed for the 51R battery and 4” intake systems.

We love the clean and simple look of the CorkSport full size battery box and we know you do also, so our goal here was to bring that same level of awesomeness to all the big power guys and gals running 4” intakes and 51R batteries.

We knew we couldn’t compromise on the fit and finish you’ve grown to love; and this new battery box doesn’t disappoint.

The greatest challenge came in the form of locating the ECU inside the box; as that is the whole point of the CorkSport battery boxes. With a bit of massaging and adjusting, we innovated a sleek solution for the ECU placement without compromising the style and fitment of the battery box.

In the original CorkSport battery box the ECU was located on the front panel. This packaged well with the full size battery and made access easy, but in order to increase the clearance for a 4” intake system we had to reduce the width of the battery box as much as possible. This required us to rethink the location of the ECU and the overall design of the battery box to accommodate it. Check out the computer drafted model below.

Moving the ECU to the side provided ample clearance for a 4” intake system and retained the standard battery location. The front of the battery box had to be extended out a bit, but this also gave us a chance to keep the wiring harness inside the box to maintain the high level fit and finish. To finish off the installation, the battery is retained with M6 studs fastened into the battery box and a 0.120” anodized aluminum bracket.

Overall the new 51R ECU Relocation Battery Box hit all the marks for fit, finish, and performance.

 

If you’re looking to downsize your battery, upsize your intake system, or are just plain tired of looking at all those unsightly wires then let the CorkSport 51R ECU Relocation Battery Box be the answer to your goal.

Turbo Kit in Development for 2014+ Mazda 3 & 2013+ Mazda 6

Since 2013 and the loss of the Mazdaspeed 3, Mazda has really left a lot to be desired as far as power goes for its line-up.

Don’t get me wrong, we love Mazda here at CorkSport; the interiors and exteriors are on point, they get great gas mileage, and are exciting to drive. We will always continue pushing and developing the platform that Mazda is kicking out, but let’s be real…we love power.

That brings us back to why I am writing this exciting blog… Sky-G is getting some TURBO LOVE.

©Car & Driver

I’ll admit, we thought long and hard about moving forward with such a large kit. We hoped, we wished, and we dreamed that Mazda would eventually wise up and kick out a GEN3 Mazdaspeed, and we got really excited when we heard about the CX-9 Turbocharged 2.5L engine. Unfortunately Mazda chose not to go down that path; once we found out about that, we decided it was time to pull the trigger on the GEN3 Mazda 3 & 6 Turbo Kit.

Moving forward on a project of this size was not a trivial decision. There were many aspects to consider:

  • Do we make a complete kit or just design and manufacturing difficult components?
  • What is the right power level to shoot for?
  • How will the engine and drivetrain hold up to the increased stress of forced induction?
  • How do we properly tune the engine?

These are all important aspects we had to consider.

Let me lay out some details and choices we made.

The most difficult and time intensive aspect of the kit is designing the physical components that will make up the kit… the entire kit. And yes, we decided that a 100% complete kit was the only way to make this a great setup, so that exactly what we intend to provide.

A complete kit needs to include everything from the air filter to the downpipe, and everything in-between. This includes the intake system, turbocharger, intercooler piping, intercooler, exhaust manifold, downpipe, and all the necessary silicone couplers, hardware, and wiring extensions.

This will be the most complete turbo kit you can purchase for the 2.5L SkyActiv-G powertrain.

Mazda-3-Turbo-Kit-CAD-Assembly

Right behind developing all the components for the kit comes the tuning. We are working with Versatune to develop the software to control the 2.5L Sky-G engine with forced induction. This portion of the project will be kicked into high gear in the near future once all functional prototypes are on our test car and strapped to the dyno.

Lastly, some thoughts to consider:

Will the engine take the added power?

How much will it hold till it pops?

Time will tell on those questions, but we do have some stuff in the works that will help. However, just spit-balling here, something around 280-300whp would be a lot of fun in the Mazda 3 and Mazda 6.

Stay tuned as this project evolves through testing and development in the coming months.

What are your thoughts on this new project? Questions?

Leave them in the comments section, we would love to hear from you.

I have only skimmed the surface of this project and I could easily write pages and pages if time allowed.

Mazdaspeed by Another Name

In the past, Mazda has said the new motors will be used across all the models.

For the past few months, Mazda has been hinting at the homogeneous charge compression ignition (HCCI) motors, but the idea goes back to 2008 when Mazda started working on their Skyactiv technology and brand. The original plan was laid out to introduce the Skyactiv I technology, and then offer a Skyactiv II phase in the future, which was to be the next step up in efficiency and performance.

Recently, Mazda officially announced the Skyactiv X after Robert Davis gave a speech announcing there is more to be given from internal combustion engine (ICE). This has been Mazda’s plan all along and they are sticking to it.

So where does the Mazdaspeed by another name come into this conversation, you ask? Mazda needs to meet its corporate goals of improving fuel economy while also ensuring performance. Right now, Mazda has the 2.5 turbo motor used in the CX9 and the 2.2 turbo diesel motors as the go-to for horsepower.

In the past, Mazda has said the new motors will be used across all the models.

I found three references where the term “supercharged” has been discussed with the new Skyactiv X engines. The term has been used in the past for both belt-driven blowers and exhaust-driven blowers.  Give Mazda’s familiarity with the turbo motors on the Skyactiv technology, my money is already on the turbocharger for gas engines.

In the past, Mazda has said the new motors will be used across all the models.

In the past, Mazda has said the new motors will be used across all the models, which means that, yes, we should see a turbocharged Mazda 3 and Mazda 6 again in the future. I know the Mazdaspeed name and Mazdaspeed 3 and Mazdaspeed 6 models are dead, but we will once again be able to play with boost in our favorite manufacturer’s cars.

Cheers,

Derrick @ CS
