Today we are launching an all-new CorkSport, a version we’re calling CorkSport 3.0. Before I get into this, let me give you some insight into our journey thus far.

CorkSport 1.0

CorkSport 1.0, when we were exclusively a reseller (1998).

Derrick and I started CS in 1998. Back then we were just two dudes (yeah, almost Lebowski dudes). We had no clue what we were getting ourselves into. CS 1.0 was crude in hindsight, but we at least had the one ingredient that mattered most: a passion for Mazda performance. We were exclusively a reseller at first. We sold products from companies like Mazdaspeed, Mazda of Japan and FEED. Check out our original logo (right) when we first launched.

CS 2.0 started when we decided to develop our own brand of parts. This started in 2002 with exhaust systems.

 

CorkSport 2.0

CorkSport 2.0, when we ventured into creating our own exhaust systems (2004).

 

It quickly grew from exhausts, to intakes, to everything we do today. We’ve changed our logo twice since the beginning. You can see our last and current logo below.

CorkSport 3.0, the industry leader in Mazda performance.

CorkSport 3.0, the industry leader in Mazda performance.

CS 3.0 starts today.

Why? We’ve grown up. Not in the sense that you wouldn’t find us going a hunski on the 5, but in the sense that our business has grown significantly, at least by comparison to our meager beginnings. Many families now depend on our business and many thousands of our customers depend on the products we develop. We’ve grown up in the sense that we’ve learned enough to know what it means to be excellent. We know what we are capable of, and we know you want excellence too. We are prepared to deliver excellence as we never have before.

There are components of the new CorkSport that you will be able to see, and there are components you will not be able to see. As for what you can see, you’ll notice a new version of our logo across all channels (our website, Facebook, Instagram, Twitter and Google+). We have a brand new website. The homepage has been totally overhauled to give you more of what you’ve told us you want. Our product pages have been revamped too, including better content and more logical organization. You can see what we mean in our re-release of the CorkSport Exhaust for Mazdaspeed 3 (honestly, there is minimal change to this listing, but you can understand how the video and images are improved). This is typical of what you’ll see from the dozens of products we are set to release in the months ahead.

Raising the Bar on Our Product Development Process

Much work went into what you can see, but even more went into what you cannot. We have totally overhauled our product development process. Our new process more robustly:

• Applies FMEA techniques to ensure a longer, issue-free lifetime for our products.
• Applies quality controls. We are demanding more from our partners than ever before, and they are responding.
• Applies quality assurance. Both externally and internally we’ve expanded our quality assurance efforts. We’ve even got a CMM (coordinate-measuring machine) in the pipeline to further expand our QA efforts.
• Collects the data you care about during the development process so that it makes it to the public (dyno testing, AFR, fuel trims, boost levels, fuel pressure, etc).
• Includes modeling and 3D printing to reduce development time and improve quality.

 

Exceptional Service

You hate back orders. So this is our goal: eliminate misses and near-misses. We want awesome, all the time. So it’s also worth mentioning that we’ve totally overhauled our supply chain management. Back orders are now 75% lower than they used to be. 

Further, you will receive a consistent experience no matter which CS part you buy. You know it, and we know it. We’ve tried to hit certain price points to make our products available to more customers, but we simply will not compromise quality to do so. To some customers CS means great value. To other customers CS means uncompromised quality at a fair price. Moving forward, you won’t see new products where we need to educate customers about what quality costs. If we have to have that discussion, we will avoid making the part in the first place. We still seek extremely high value but the bar has been raised for what CorkSport quality means.

We thank you for your support for the past (almost) 17 years! You’ve allowed us to grow our business large enough that it fills an entire city block. We are, by far, the #1 source of new products in Mazda Performance.

We will continue to return the love by supporting only the Mazda brand. We are Mazda performance to our core.

Regards,

Rich Harris

This post is part 2 of a 2-part series on the importance of injector seals. If you’re just now discovering this post, be sure to tune in to part 1 before continuing here.

___________________________________________________________________

Like the title says, you need injector seals for your MZR! Here’s why.

When Mazda designs a part, they design it with the “typical” customer and OEM power in mind – not the power hungry, boost craving driver.  Yeah, I’m talking about you and you know it – and we have just the thing to keep you and your MZR in check.  As you add more fuel and more boost, the weakest link is eventually going to give. That link is the OEM injector seals.

Three Reasons You Need Injector Seals For Your Mazdaspeed

  1. Reliability is sacrificed using the OEM seals.
  2. Leaking seals causes loss of power.
  3. Inconsistent performance is caused by leaks.

So, if you are just tuning in to our blog, then shame on you, go read part one like everyone else! With that, let’s dive into the design of the seal and how it works.

We put 500 hard miles on the Speed3 and here are the results.  500 miles may not sound like a lot, but the company owned MS3 does not live the normal life. It spends most of its time on the dyno testing new products pull after pull, may have hit 35psi, and when it does hit the streets, it’s driven by an employee searching for the governor speed.  I think we can all agree that the 500 miles was a fair amount of abuse to put the injector seals. Plus, other sets of seals have been running in alpha testers vehicles for thousands of miles without issue.

Now that we have that covered, let’s talk a bit more about the design of the seal and how it works.

Injector-Seals-Mazdaspeed-MZR-Engine-Tokay-

It’s no longer just a washer with one sealing surface – it’s a cup. So it seals in the OEM location AND along the side of the cup. The secret is in the design (which is all thanks to @Tokay444 from MazdaSpeedForums).  The lip at the bottom of the cup is flared just a bit so that it crushes down tight against the cylinder head, and as it crushes down it also crushes outward, pushing against the wall of the port much like an O-ring. If you are having trouble visualizing the flared lip crushing outward then check out the image below. Time to get technical!

FEA-COrkSport-Injector-Seals

Looking at this side view of the seal, you can clearly see that the flared lip is extended further outward than the side of the seal. (Please note that in this FEA, or Finite Element Analysis, the deformation scale factor is 6.5:1, i.e. highly exaggerated). This design is what separates the CorkSport seal from any other seals on the market today. In the FEA the seal is subjected to 3300lbf in the direction of the arrows; 3300lbf is the approximate clamping force of an M8x1.25 torqued to 18ft-lb. The areas in red indicate a displacement of 0.0057 inches, which is just enough to begin yielding (permanently bending) the beryllium copper material. After the 500 miles of use, we had the four seals precision measured using a CMM (Coordinate Measuring Machine). On average, the seals yielded 0.0015 inches confirming our FEA.

Still following?

So what does this mean to you? When you torque down the fuel injector bolt and clamp you are applying approximately 3300lbf to the injector seal. This crushes the seal downward pushing the flared lip outward into the wall for ultimate sealing strength; and we have all the data to prove it! The CorkSport seal works flawlessly, but because of the design they are not reusable like any other crush seal.

So, now that we are done with all the technical stuff let’s take a look at the used seals. First, I would like to remind you what the injector looked like with the OEM crush washer and only 4000 miles.

Injector-Seals-Mazdaspeed-MZR-Engine-Tokay-Info-Tech-Injector-Fuel

Extremely dirty with an excessive amount of combustion gases blowing by the OEM injector seal. This makes for a very unhappy MZR. Second, in the images you are about to see, the seals have not been cleaned in any way, shape, or form. I pulled these out of the car and immediately took the pictures. Prepare to be WOW’d; I know I was…

Injector-Seals-Mazdaspeed-MZR-Engine-Tokay-Info-Tech-Injector-Fuel-2

 

Injector-Seals-Mazdaspeed-MZR-Engine-Tokay-Info-Tech-Injector-Fuel-3

Besides the clean injector body, there is a more subtle detail that needs to be pointed out. If you look at the very edge of the flared lip on the seal you will notice that the black soot does not go all the way to the edge. This further confirms that the seals are working the way Brock (@Tokay444 on MSF) had envisioned them and we can also see this “clean ring” in the cylinder head below.

Injector-Seals-Mazdaspeed-MZR-Engine-Tokay-Info-Tech-Injector-Fuel-Inside-Intake-Manifold

In the image below you will notice that the seal is dirty on the inside, but that’s okay – that happens by design. The “shelf” that you see midway up on the inside of the seal seals against the injector body instead of in the OEM location further down around the injector nozzle. This change in sealing location allows the flared edge to deflect how it needs.

Injector-Seals-Mazdaspeed-MZR-Engine-Tokay-Seal-Dirty

If I haven’t convinced you yet why you need injector seals for your Speed3 then you’re hopeless…you should go get a Civic or something else that’s slow…

Injector-Seals-Mazdaspeed-MZR-Engine-Tokay-Full-Injector

Between our results and the reviews given to us from our alpha testers we have great confidence in the seals and you should too! Keep an eye out for these to be released very soon! Zoom – Zoom! -Barett, CS Engineering

According to Ryan Beene at Autonews.com the next Mazdaspeed is planned for 2017. At first glance we might assume that this is purely more rumors, but upon further inspection we see that there might be cause to believe him.

Why?

First of all, Ryan Beene has been vouched for by several other automotive sites and journalists. Over at thetruthaboutcars.com they state “Having known Beene for a number of years, I can say that his information is to be trusted more than the typical buff book “anonymous sources” accompanied by some fanciful colored pencil sketch or computer rendering.” Jalopnik.com also states: “Automotive News’ Ryan Beene, who has covered Mazda in depth, is rather reliable. This is a good thing.”

So apparently we should listen. We also see some of the first reasonable explanations for AWD and a Turbo. As we have discussed previously, the new Mazdaspeed will most likely share the AWD from the CX5 platform. See the article here: http://www.corksport.com/blog/will-there-be-a-new-mazdaspeed-3-with-all-wheel-drive/ where we also happen to quote Takeo Mariuchi, the program deputy manager as saying “from a technical point of view it’s not difficult to install a four wheel drive system”. We also showed some interesting photos showing the rear of the CX5 and 2014 Mazda 3 that appeared as though it would be rather simple to add the AWD.

Nonetheless we put our stamp of approval on this statement.

The second thing that he brings up, that we can stand behind, is the fact that he believes the engine will be the same as the one used in the CX-9 launching that year. This would not surprise  us at all since it would help shave cost, and engineering work on Mazda’s behalf.

There is a lot more info in the article, so feel free to read the full article here: http://www.autonews.com/article/20140825/OEM04/308259975/mazda-making-big-changes-fast

COrkSport-Chris-Childress-Mazdaspeed-3-Mazda3-Mazdaspeed3-Rumor-2017-Release

I’ll summarize the rest of his interesting points here otherwise:

Mazda 2: Redesigned Mazda 2 production starts in November and he expects a sportier Mazda2 with a modified intake and exhaust as an option.

Mazda 5: This will get killed off by 2015 due to lack of interest.

Mazda 6: An interior redesign for 2016, new center console, smaller dash that sits lower. Similar to the Mazda3.

Mx-5 Miata: Debuts in one week. Will have a SkyActiv 2.0L liter engine (no word of a turbo). More exciting though is the news that Mazda is planning a fastback-style hardtop version.

Rotary RX-7 or Rx-9: They are still working on it, should be 2 seats, not 4. No word on when.

CX-3: This should go on sale next June. Built on the same platform as the Mazda2.

CX-5: Fresh interior for 2016 and new front and headlights.

CX-9: Redesign for 2017 with new KODO language. Turbo Engine 2.5L that will be the same as the Mazdaspeed 3.

 

Of course, Ryan still doesn’t quote any sources or give any proof, but we definitely are willing to believe all that he says!

 Real Quotes from Mazda’s Global Sales and Marketing General Manager

Mazda-Auto-Adapt-for-2020-CorkSport-Mazdaspeed-RX7-Rx8

Once again Motoring.com.au has brought some rotary rumors to surface thanks to an interview with Yasuhiro Aoyama, the General manager of Global Sales and Marketing. So what did Yasuhiro say that is so revealing?

“this is a very fantastic idea, 2017, [for] a new rotary.”

followed by

“We celebrate the anniversary of rotary in 2017; 50 years. Then 2020 is the Olympics in Tokyo and the 100th anniversary of Mazda,” 

When prodded for more info and whether we would see a halo car in 2020 he was quoted as saying: “We will defy convention”.

In order to prevent us from expanding on his words without the proper quotes let us list them all here:


“We have our own definition of sports and our own definition of how to get Jinba Ittai, the oneness between car and driver – and we do not have to necessarily compete with segments or competitors,” he said.

“We won’t follow them just for the sake of it.” [in reference to other car companies]

“We are indifferent to the successes that our rivals are making; we need to make our own success and forge our own way forward.”

And one of the quotes that I find most exciting was this:

“Lightweight is one of the core elements for our sports cars to have high performance, so all of the vehicles for the next generation will be like this,” he stated.

 

What could this all mean? Well that Mazda again has neither confirmed nor denied the idea of an RX-7 in 2017, and that it “is a very fantastic idea”, and that it it will definitely be a lightweight vehicle. We also know that he is hinting at something in 2020? Possibly a halo car? Possibly the RX-9 that they trademarked awhile back. (source)

Nonetheless, we are already stashing our pennies so that once we have official word, we can start yelling “Take my MONEY!”

How Mazda, a Strange Recycling Symbol and Dorito Chips all Connect

CorkSport-Logo-Connected to Mazda

 

What is this symbol? And how is it connected to Mazda? On first look it appears to be somehow symbolizing recycling, or Rotary Engines,  and if that was your guess, you aren’t really wrong. But, there is certainly more.

This is the logo for a Motorcyle Company known as Van Veen that produced cycles from around 1972 until 1981. Van Veen was run by Henk Van Veen a dutch importer of motorcycles who had a crazy idea to cram a rotary engine into a motorcycle. So, he chose a bike, a Moto Guzzi V7 as the frame, and then an engine.

Van-Veen1-OCR-1000-Rotary-Engine

Now, contrary to much of what you see on the internet (such as wikipedia) stating that his first prototype used a Comoto Rotary, Van Veen actually chose another engine. A Mazda rotary.

The first engine this slightly crazy man decided to cram into those bikes was none other than the same engine that Mazda used in their RX2, the 10a.

Mazda-Rotary-Engine-Motorcycle-Guzzi-Wankel-CorkSportThough the initial prototype used this engine, Van Veen sadly began instead using the Comoto rotary instead.

Alas though, after just a few years of selling his OCR 1000 wankel rotary bike, the company stopped producing them in 1981. As much as we wished he continued to use the Mazda engine, he did not, but that original prototype still exists. If you happen to read Dutch, check out more here: http://cybermotorcycle.com/docs/downloads/vanVeenMotorRijwiel.pdf

Though we never got to see them use the Mazda engines for production, or later start using the RX7 engines (boy that would have been awesome!), there have been others that have followed in Van Veen’s path and built Mazda rotary cycles.

Here is a custom built 13b powered rotary bike by Rodney Aguiar.

Who knows, maybe one of these days Mazda will even start making rotary motorcycles! After all, they did start by making 3 wheeled cars!

Renderings, Concepts, Images and Rumors about the Next MX5

Mazda recently released an official image of the next 2016 Mazda MX-5 Miata. Sadly, it is blanketed. So though we can tell the overall shape of the car (spoiler alert, it looks like a car) we can’t see much else. What we can do though is speculate.

Here is the official Mazda image:

 

2016-Mazda-Miata-Mx5-Spied-CorkSport-Mx5-2-Under-Blanket

 

Now, though we all probably want a fancy, blanket draped MX-5, I have a feeling that some of us plan to actually drive it, and not keep it under wraps in our garage. So, I decided to pull from the web some next generatino renderings of the MX-5. Which one do you think most resembles Mazda’s official image?

But, moving on. If you’ve had enough of renderings, let’s check out the engine. This shot of an engine bay is supposedly from a source that found the little Miata mule at a port on the west coast months ago. The big news here is that it’s a turbo. The question, is if this is going in the Miata for real, or if it’s going in the Fiat/Alfa since Mazda has partnered with them. (source)

 

So, though we leave you today with nothing but more rumors and speculation, we again see some pretty solid evidence of a good looking, and possibly turbocharged, 2016 MX5 Miata.

Oh, and don’t forget this video from Mazda.

(P.S. do you hear a turbo?)

Is the Next Mazdaspeed already under our Noses?

We talk a lot about the next Mazdaspeed, will it be AWD, will it be FWD, will it be a 3? the 6? a 2? Though little is known or confirmed, I want to point out a few things we DO know as a fact.

 

Mazda has been working on their SkyActiv D engines for a few years. They have already shown their SkyActiv D engines, they even race them. What many people fail to realize it that the SkyActiv D runs in the Mazda 6 with a two-stage turbocharger.

Two-stage-Mazda-Corksport-Mazdaspeed-Turbocharger

The two-stage turbocharger gives you the best of both worlds, it will run a smaller turbo in the low RPM range in order to give you more power and cut emissions, then at higher RPM ranges it flips a lever and runs the bigger turbo to produce more power with no noticeable lag between the two. According to Mazda’s own website “SKYACTIV-D utilizes a two-stage turbocharger in which one small and one large turbo are selectively operated according to driving conditions.” (Source)

 

What else do we know? Well, Mazda has been actively racing the SkyActiv D engines in several endurance races. This is a mildly modified version of the SkyActiv D that is known to put down about 400hp.

 

 

So why would Mazda try and rework a new regular gas powered engine with a turbocharger for the next speed? Why not take the 400 hp Two-Stage turbo diesel that they already have, and pull a little power from it, and release it as a street legal vehicle?

More questions: Why has the SkyActiv D release been delayed? Is it emissions related? According to Mazda their engines pass with flying colors, no treatment necessary. So it can’t be that. In fact when the SkyActiv D was delayed Mazda spokesman Jeremy Barnes was quoted as saying: Skyactiv technology can meet it [emissions] — and it can — but the challenge is engineering a car that delivers the kind of performance that a Mazda needs to have and we’re unable to do that given where we are right now.”

Wait a minute. So what you are saying is that the 2.2L passes emissions, (source) but doesn’t have enough performance? If Mazda has already passed the emissions testing for the engine then why delay it. We know they have released it in the CX-5 in other markets, they even confirmed they will be releasing it in the Mazda 3 in Australia come September. (Source) Along with this the CX-5 has been selling in Japan at a rate of “four 2.2L SKYACTIV-D purchases for every one 2.0L SKYACTIV-G.” (Source) So why would they work on a turbo gasoline variant when the Diesels (which already have a turbo) are already clearly being sold at such a significantly greater rate? My answer? I don’t think they will.

So what’s the delay. My guess is that they plan on announcing the SkyActiv D release date at the same time as the performance oriented version, the Mazdaspeed SkyActiv D which may be a variant of the engine seen above. Even the SkyActiv D that is currently running in the CX-5 pushes 310 lb ft of torque and 173 hp. Still impressive, especially that torque! Imagine bumping the hp by even 100 and the torque would be incredible!

Last but not least, check out these two videos from Mazda that were released almost 2 years ago. Starting at minute 2 they say some interesting things.

“An exceptionally high redline or 5200rpm. When we were done we had created a beast … delivers the driving performance of a 4.0L V8.”

A 4.0L V8!!  Just do a quick google search for standard HP from common 4.0L V8s and you should be more than impressed with the results. Is this Mazda teasing us and we just failed to notice?

In the long run, whether we get a Mazdaspeed version of the SkyActiv D or not, I can’t wait until it hits our shores for good. Let’s hope it’s soon!

 

Until next Time,

Diesel Hybrids May be Released by Mazda

 

We all know Mazda has been working on Diesels for the US market, and that they have already been released in Europe, Australia and other places. We also have seen Mazda’s electric Demios (Mazda 2). Well, now we have just heard from torquenews.com that Mazda might be releasing a Diesel Hybrid.

Mazda hopes to release a vehicle that can hit a greater gas mileage than the Prius C (50mpg) which is the leading seller in Japan (known as the Aqua). Of course, we are doubting that even if this wonder vehicle gets created that we would ever see it in the US, but we can hope. At this point we are still hoping for Mazda to simply release the Diesel CX-5 and Diesel Mazda 6.

SkyActiv Diesel

mazda-demio-ev-front-corksport-

 

Would you trade the extra emissions of a diesel vehicle, for the extra emissions it also produces? If you keep an eye on the current cars that Mazda is racing, we see that the most prominently featured are all diesels. Whether it is the several Mazda 6′s racing with their Skyactiv-D engine, or the Mazda Prototypes #00 and #70 (source) Mazda is definitely focusing on their diesels.

 

Ultimately we know one thing, the Hybrid Diesel won’t be making it to our shores anytime soon, and it’s unlikely it would make it before their standard diesel.
