Introducing: The CorkSport Performance Polyurethane Exhaust Hanger Kit

The exhaust system on your Mazda is a loved and cherished part of your car’s character and performance.

It emits glorious sounds that keep you entertained and smiling from ear-to-ear, but if you can believe it, is only attached to your Mazda by a few soft rubber hangers.

Yes, your hard earned stainless steel exhaust is ONLY suspended by small pieces of rubber…

Here at CorkSport, we think it’s time that you show your exhaust system some love… it’s time to take the rubber off.

We present to you: the CorkSport Performance Polyurethane Exhaust Hanger kit.

This kit replaces the four rubber exhaust hangers that would otherwise be used to mount and suspend your CorkSport Performance Exhaust System; the two rear hangers on the axleback section and the two mid-pipe hangers.

But why is polyurethane better?

Well there’s a few reasons:

  • First, polyurethane is more durable and heat resistant than rubber so the hangers will perform better for a much longer period of time.
  • Second, and most important, the polyurethane used in the CorkSport Performance Kit uses a stiffer compound compared to the OE. The polyurethane hangers have 75A durometer stiffness vs the OE rubber at as low as 50A durometer. The increased stiffness helps minimize the movement of the exhaust while still providing the necessary flex between the car chassis and the exhaust system.

All-together, this means your performance exhaust system for you Mazda 3, Mazda 6, or Mazda CX-5 will not be able to move around under the car during spirited driving such as back roads, auto-crossing, or whatever motorsport event you prefer.

Keeping your exhaust system in places reduces your chance of damaging your beloved Mazda or the exhaust; it’s a win/win.

The First CorkSport Branded Ride Mod + Vote For The CBR Graphics!


For those of you who have forgotten or who did not see the initial post we recently purchased a brand-new 2018 Mazda 3 Hatchback. Dubbed the CorkSport Branded Ride (CBR), we set out to start making it less like your mom’s car and more like something that suits the CorkSport name.

We turned to you all for suggestions and got some great feedback. We heard everything from wide bodykits, “slam it to the ground”, turbos and engine swaps, to easier mods like wheels, coil overs, and a new front lip.

We’re sure you’re anxious to find out where we’ve started: Intake? Exhaust? Springs? Our choice might surprise you.


But before we dig in to the first mod for the CBR, we first want to give you guys an opportunity to do something really fun:

Vote To Pick One of The 4 Graphic Concepts For The CorkSport Branded Ride!

Following up on our introduction to the CBR, our team here has decided to involve you guys in a whole new level of making this car look sick: Body Graphics!

Not only are we asking of your ideas and feedback for the mechanics of the CBR, we want you to decide on the aesthetics too. We want YOU to choose what this things actually looks like.

 
Our design team has developed 4 different concepts for the CBR graphics, and we must admit, they look pretty sweet. The concepts bring in a bunch of different styles, from racing to street, and are sure to make this baby an attention-grabber.

Here’s where you come in: We need you to cast a vote for your favorite concept for the CBR.

A few different ways you can vote:
  1. Repost a pic of your favorite concept with #CorkSport & #CorkSportCBR on social media so we can see your vote. Then, tag a friend and ask them to pick their favorite!
  2. Comment on one of our CBR social media posts for your vote with #CorkSport & #CorkSportCBR.
  3. Leave a comment on this blog post with your vote.
Here’s an example:
“So stoked to get to pick the design of the #CorkSport Branded Ride! My vote is on Concept #3 for sure. – @TagYourFriend, what’s your vote?? #CorksportCBR”

We will gather votes together and whatever concept the CorkSport Community chooses will ultimately be brought to life on the real CBR!


Now, on to the First CBR Mod:

 
We did not want to go crazy right off the bat, so we looked at where the average Mazda 3 owner might start. Maybe a license plate kit, short ram intake? Catback exhaust? Lowering springs? – All good guesses.

We decided to go for a reliability mod that many people may not consider right away: a CorkSport Oil Catch Can kit.

Now, why would we install this right away on a brand new car? It shouldn’t have any issues with engine health. – Well, that’s the exact reason we installed it.

If it doesn’t have any issues right now and the engine is clean and new, then why not keep it that way?
As an engine operates, oil mist, fuel vapor, water vapor, and other gases can pass from the crankcase to the intake using the stock PCV system. Over time, as these gases condense, they form gunk and carbon buildup on valves, piston tops, and other vital engine components. An oil catch can exists to catch all of the oil mist and other vapors before they get back to the intake and dirty all of the nice clean engine components. Additionally, these other gases do not do any favors to the combustion cycle. – Just ask anyone who has emptied one during an oil change; what an OCC collects is pretty nasty.

Now let’s get to the install.

Locating the can itself is a snap, and finds a home in the driver’s side fender well. Routing the hoses is the difficult part, surprisingly, as you have to gain access to some of the factory PCV hose. This means removing the air box, intake tube, and even the starter. Once the factory hose is removed, the new hoses are installed and routed to the OCC.

Finally, we added the ball valve to the bottom of the CorkSport Oil Catch Can, which means next time the CBR needs an oil change we have an easy way to drain the OCC as well.

So what’s next for the CBR? That’s completely up to you!

Help us decide by submitting ideas for what YOU would do if this was your car.
REMINDER: We will give you cred for submitting an idea that we use for the mods. In short: This means Your Name will actually be put on the CorkSport Branded Ride!
Stay Tuned, you’ll be seeing more of the CBR soon.

Remember to cast your vote for the CBR Graphics!

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!

Dear Car Clubs: We Want To Hear From You!

Dear Car Guy,

Did you know there are LOTS of Car Guys and Gals out there in the Mazdaspeed world?

From Nator Clubs and Mazda Nova Clubs to Mazdaspeed and Meet Up Clubs, the branding is slightly different for each area and each group, but the heart and soul of the people who get involved stays the same.

Great people, big appetites (for speed and food), awesome tastes in beers and booze, and a genuine care for their fellow club members. I have made sure to attend meets and get to know the nitty gritty center of our Mazda Community, mostly because who doesn’t want to do Car stuff with their Car friends. However, I also do it because it’s an integral part of CorkSport’s vision, to give unprecedented levels of customer support and connection to the Mazda Community.

We ultimately just want to LOVE OUR CUSTOMERS, and I’ll take one for the team and meet you Guys and Gals face to face.

We’ve been to the MidWest Nator meet, the East Coast Nator Meet, and the Boise Mazda Take-over event this past year. We have also hosted our CorkSport Dyno day and given the west coast Mazda community a place to gather as well! Let me just say, it’s been amazing getting to know everyone, and seeing some awesome familiar faces.

The one thing that really stands out for me is the sense of community that is built at the center of all of this. I’ll admit I’m a people person, so of course YOU are my favorite part of working for CorkSport, however, it’s a community like no other, regardless of the title it goes by. The values of the Mazda community stay fairly similar, with mods, install days, track days, meet ups, and expansion of the love we all share for the Mazda Platform.

A group of awesome individuals, getting together, teaching those who don’t know how, and taking are of those who do (and still break down).

There are Groups all over the US (and I’m sure international), that we don’t even know about. It’s my hope that when you read this, you pass me your group pages, club names, social addresses, etc., so that CorkSport can help others in your area connect!

Near and Far, no matter where you are, let CorkSport hear from you!

Until next time, stay safe, stay fast, stay happy my friends!

Track Tested CorkSport Approved AXM Parts – Leading the Pack.

The last race weekend I had available before the runoffs turned out to be pretty interesting.

Locally there are very few T4 (touring 4) class cars so I often find myself running with other class cars and this weekend was no exception at Portland International Raceway. I showed up for qualifying on Friday morning with a new part to test and a suspension setup with something I had not tried.

I looked over the entry list the day before, and there read a list of cars you would expect to clobber a Mazda 3 on the track. 3 Porsche 911s, a pair of V8 mustangs, an STL Miata and more.

To make sure I had a clear track for qualifying, I hustled to the pre-grid to make sure I was the first car out. Straight out of the pits, I went flat out to get some distance on the Porsches to be able to push the car for the entire time I was out qualifying. As I watched the lap timer in the Mazda 3, my times kept dropping lap after lap. 6 laps in and I had already bested my fastest lap time at Portland by a second, so I called it quits and pulled in to the pits.

On the way out of the track I grabbed the time sheet to review and see where I placed. A quick review of the sheet showed I had qualified the Mazda 3 in second out of 10 cars and I was in front of 2 of the Porsches.

The start of the race didn’t go that great. Out of all the cars on the track I was in the bottom ½ for horsepower. But I was making up the speed in the corners.

One of the back cars jumped the start a bit and managed to take us 3 wide into a corner which is only good for 2. I was forced to give up some room to one of the Porsches to keep from having contact which put me back to 4th. Several laps into the race one of the Porsches who got ahead of me at the start spun off the track so I was able to move back up a spot while trying to chase down the leader who was running ~1 second a lap faster than I was. The 30 minute mark came pretty quick, and the race ended on a not-so-exciting note of me being in 3rd, and the leaders ~ ½ a lap ahead and all but a few of the rest of the field being lapped.

The big question you all want to ask is: “What were you testing for the 3rd Gen Mazda 3?”

First things first, the changes we made to the Mazda 3:
  • We made an adjustment with the CorkSport rear adjustable swaybar. Being able to make quick adjustments on the rear swaybar bar allows us to soften the suspension to match the alignment changes.
  • We had taken more rear camber out of the back of the car with the CorkSport adjustable camber arms, trying to decrease rear grip (yes you read that right). We have been having problems with front end push (understeer) so we worked on dialing rear grip out of the car.  – We had the CorkSport front camber plates maxed out for camber to the class limits, but it wasn’t enough to offset the rear grip.
  • We originally were running our CorkSport Mazda 3 adjustable shocks on the track but we had to remove them as they are not legal for the Touring 4 class. The adjustable shocks make a world of a difference over what I have to use on the car and I wish we could’ve changed back. Being able to fine tune the Mazda 3 suspension is a great asset for any performance driver.

Now to the fun, what I got to test that was new:

The engineers here at CorkSport have been working on a revised Mazda 3 Rear engine mount for the 3/6/Cx5 over the past few months. The best way we have to extreme test parts is on the track.

Think of the race-testing this way: I am driving full throttle, banging gears, and when I am off the throttle means I am on the brakes, so there is no time for the mount to get any rest. There is the maximum amount of heat, load, and stress in a compressed time line, compared to street driven cars, so if failure is to occur it would be on the track.

At the end of the month, I will be doing a test on a final version of the rear engine mount at the SCCA Runoffs and competing to bring home a National Championship for CorkSport and Mazda.

This brings me to my next point: All of the parts mentioned above have been punished on the track and had zero failures. I have been on the same rear sway bar, rear camber arms, camber plates, and short ram intake, and cat back exhaust since we started racing the car at Daytona in 2015.

You just can’t beat the fact that our CorkSport parts walk the talk when pushed to the extreme, which means they won’t let you down, no matter what you’re doing.

Charge for the WIN!
