We asked the CorkSport community for their ultimate Mazda performance questions for our new series, Ask the Expert. From the good to the bad to the weird, here are the top four questions straight from CS fans and our engineer’s answers.

Your top Mazda performance questions answered by our experts.

Owner: @sikemantana Photography: @konceptphotography

Q: What is the maximum horsepower you can get from a MazdaSpeed 3 with just bolt-on’s?

A: With the typical bolt-on performance modifications from air filter to exhaust tip, you should be in the 320-330wHp and 340-360wTq range. You may be able to up those numbers a small amount with an E85 mixture, but for some locations that is not readily available. This is not including an exhaust manifold, intake manifold, or larger turbocharger. Now, if you were to add the exhaust manifold, intake manifold, and larger turbo (this being the largest power gain) then you will quickly find the limit of the fuel system at the 380-390whp range depending on the fuel grade/type.

Q: Will a supercharger/turbocharger kit become available for the SkyActiv platform?

A: This question has been stirring around since the release of the SkyActiv platform. With the release of the MX-5 with the 2.0L in the U.S. and the 1.5L in foreign markets I would not be surprised to see a supercharger and/or turbocharger kits being released in the next 1-2 years.

Q: What’s the boost threshold on the CorkSport Performance Drop-In Turbocharger?

A: We don’t have a compressor map to quote from, but I believe I can answer this fairly accurately from my knowledge and experience. The CorkSport turbo will be the most efficient in the 1.75 – 2.25 pressure ratio range. This equates to approximately 11 – 18psi, but this doesn’t mean the CS turbo will fall on its face in the higher boost levels.  Due to the more efficient design of the forged billet compressor wheel, the CS turbo should stay above 75% efficiency until around pressure ratio 3 (30psi), and then begin to fall off a bit.  At around pressure ratio 3.5 (36-37psi) you will be very close to the maximum shaft RPM for safe operation, so I wouldn’t push it past that. Either way, if you are running the CS turbo above 30psi, then bravo sir. I’m sure you have a very fun car.

Q: Here’s a hard one. If I have a manifold, which calipers should I buy to get a better exhaust sound?

A: Well the issue is you weren’t clear enough with your collection of parts. First off, what kind of manifold are we talking? Is it the manifold forged from Unobtanium with the blood, sweat, and tears of Santa’s Elves or is it the one and only manifold hand fabricated of carbon nano-tubes in the R&D lab at Koenigsegg designed by the alien race called…The Stig? And then you have the caliper… Do you mean the kind that grip locks the ferrous circular structure utilizing kinetic friction to cause conductive and convective heat transfer ultimately converting mechanical energy into thermal energy until it comes to a squealing stop or the kind that measures to the 0.001” and was used to design aforementioned caliper? See how I’m a little confused? Now we have four combinations to pick from and I could explain each and every one of them in great detail, but I don’t want to bore you. So the one I would pick goes as follows: Your cold start announces your presence like the trumpet of the Greek God Zeus riding his chariot into battle followed by your WOT pull roaring like a thousand lions chasing down a heard of Zebras.

What other performance questions do you guys want our experts to answer?




As we eagerly await more news about the 2017 Mazdaspeed 3, it’s easy to become distracted by a wish list of features, making us forget about the Gen 1 and 2 marvels sitting in our garages.

We’ve hoped there would be a new Mazdaspeed 3 sooner than now, but the compensation of waiting is owning and driving Gen 2 (or Genjuan) Mazdaspeeds every day. Sure, we’re a little biased, but there’s a reason our lives are centered around Mazda performance enhancement. Maybe we’re just feeling nostalgic because it’s #ThrowbackThursday, but whatever the case, the Limited Slip Blog’s 2013 review of the last Mazdaspeed 3 reminds us: Even a few years old, these cars remain incredible.

Christopher Little takes a mean shot of the MS3.

We stumbled across this blog entry after finding that killer shot above, taken by cofounder Christopher Little. If it wasn’t clear from the entries that cover just about every car under the sun, it’s obvious just glancing at their photography that these guys have a passion for vehicles, something any self-respecting Mazdahead shares.

Gen 2 Mazdaspeed 3 from Limited Slip Blog

Chris had some issues with the interior—but noted the Gen 2 Mazdaspeed 3 had the best visibility of any hot hatch he’d driven. His description of the first time he actually drove the car probably sounds like what a lot of us experienced when we first got behind the wheel of a ‘speed. The word “intoxicating” stands out, which shouldn’t surprise anyone who understands Mazda power. The Mazdaspeed 3 makes it just about impossible to drive without experiencing some raw joy, which Chris did. We get it; that’s why we devote our lives to Mazda performance, to bring even more power out of these beauties.

The Mazdaspeed 3 has always been a stunning and, yeah, intoxicating ride. It’s been great for almost a decade, and with the new generation coming out soon, we don’t expect that legacy to change.

So you want to become a professional racecar driver. Awesome plan, I mean who doesn’t right? But where do you start? The answer is Mazda.

Mazda can help you become the race car driver you always wanted to be.

Hop on Craigslist and start looking for a car. You’re going to need a good solid platform to start with and something that’s easy to work on. A car that is relatively inexpensive, easy to find parts for, super reliable, and can give you the best driving experience along with great aftermarket support for future upgrades. BAM you just bought your ‘91 Miata racecar. A car that has everything you need and then some.

First things first, you need to make sure it’s safe and in tiptop shape to handle the abuse you’re about to put on it. Go on the hunt for pieces you need to replace like brake pads, shocks, and maybe a wheel bearing or two. Don’t settle for some cheap aftermarket pieces. You are going to be racing this car and don’t want to lose a track weekend because of premature part failure. You need OEM top notch quality.

Mazda was the first company to offer a support program for their grassroots racers. The Mazdaspeed Motorsports Development program sells OEM parts to drivers at cost in order to keep them on the track longer. If you provide them with at least two current race results within the past 12 months you can join the program and reap the benefits they have to offer. Along with parts, you also have access to trained employees and other racers who can provide help and guidance.

Once the car is ready to go, you need a place to go racing. Mazda has partnerships with some of the largest sanctioned racing bodies such as SCCA Solo, NASA, and SCCA Club Racing. With over 20,000+ racers, it’s easy to see why more Mazdas are raced on any given weekend than any other brand in the world.

So you have been racing for a year or two and you’re ready to take it to the next level. Introducing the Mazda driver development ladder system, the one and only true program to help guide you from the grassroots level of club racing to the high ranks of Indy lights. If you really have what it takes, the skill and the character that Mazda embodies, you may be lucky enough to find yourself in the cockpit of a Mazda prototype racing in the Tudor United Sports Car Championships, the most prestigious road racing campaign in North America.

We all know racing is expensive. The cost of gas, food, entry fees, and travel can add up quickly during a regular season. Who can help you pay for these things? Mazda of course. As a competitor in the Mazda ladder system, you have the ability to compete and earn scholarships worth thousands of dollars to help you pursue your dreams. Imagine winning the run-offs or the MX-5 cup and being awarded $75,000 to help fund your racing expenses. Now that’s what I call support.

Mazda also created the R.A.C.E program in 2014 to help motivate and engage the next generation of STEM (science, technology, engineering, and math) professionals. They dedicated a whole program to developing young minds and helping them pursue their dreams even if it has nothing to do with racing cars. You can’t tell me that is not cool.

Mazda is the true racers brand. From mentoring to scholarships to the various after school programs they have invested in, no one is as committed to the driver as Mazda is. They breed the next generation of racers. A brand built by the people for the people. The reason #DrivingMatters.

Happy racing,




Keep your car clean even with your dog as your passenger.

We all wish we could keep our cars clean and pristine at all times, but sometimes life happens. As much as we may love them kids and dogs are particularly skilled at destroying our cars. While you can’t completely avoid the messes they bring, these five tips will help protect your car against their havoc.

1. Use a designated dog blanket

Drape the blanket over the seat your dog sits in—which should be the back seat to prevent any injury to the dog in the case of airbag deployment. Felt usually works best because it acts as a magnet for dog hair. More hair on the blanket means less hair on your seats.

2. Plastic wrap the windows

Yeah, it may sound strange, but this tip comes straight from racecar drivers. If your dog (or toddler) has a tendency to slobber all over your windows, take a sheet of plastic wrap and push it tight to the window. Then, when you’re done driving, pull the wrap off the window. Boom. Clean windows and no clean up time.

3. Invest in all weather or heavy-duty floor mats

Did the kids jump into the car with muddy boots? Of course they did. If you keep good floor mats in your Mazda, though, it’s nothing a quick spray down can’t fix.

4. Put something between the car seat and your actual seat

Kids = spills. Protect your seats by putting a towel that’s the same color as your seats under the car seat. Now unexpected spills can be cleaned up with just a load of laundry.

5. Lint rollers and wet wipes to the rescue

Even with all the mess-proofing you do, a mistake or two are bound to happen. In this case, keep an emergency stash of lint rollers for the pooch hair and wet wipes for kiddo spills in the glove compartment. And an air freshener never hurt anyone.

These tips will help protect your baby from your babies. What do you do to keep your Mazda safe from little ones and four legged friends?




Introducing, the new and improved Front Mount Intercooler Kit for the 2010-2013 Mazdaspeed 3. The CorkSport FMIC piping has been redesigned from the ground up, providing better fitment, better looks, and better performance.


Figure 1: Assembled Small Core FMIC Kit

What sets the CorkSport FMIC piping apart from its predecessor and the competition? The secret is in the new piping design. Let’s start with the typical “pain points” associated with a FMIC kit. When going from the TMIC to the FMIC, you are adding a considerable amount of piping and volume between the turbo and the throttle body. Most people believe this causes “turbo lag” which is true, but not nearly to the extent that the internet wants you to believe.

There are two components to the charge air that are coming from the turbocharger: pressure and volume. There are also two components to the “turbo lag” everyone curses: pressure and throttle response. Pressure is easy to explain because it’s measurable, but volume and throttle response are a bit more difficult and very much related.

Imagine walking into your local convenience store to grab a big fountain drink and without thinking you grab the biggest straw you can find. You’re not going to use the coffee stir straws right? You would never be able to get enough soda to quench your thirst! Basically, your engine is dealing with the same issue until the pressure from the turbo makes its way through the FMIC piping. This is the importance of volume! So how does this relate to the CorkSport FMIC?

The CorkSport FMIC piping takes volume to the next level for improved performance and drivability. Looking at Figure 2, you will notice that the last two 90-degree bends, just before the throttle body, are a bit larger diameter than the rest of the piping. By increasing the diameter of the pipe directly in front of the throttle body, we create a large reservoir of cold air for the engine to suck in as soon as you roll into the throttle. Having this larger volume of air immediately available to the engine greatly improves drivability and throttle response because it fools the engine into thinking it has a larger intake plenum than it really does. The 3.00 inch section provides approximately 51 cubed inches of added volume over 2.50 inch piping, that’s an 18% increase.

Figure 2: CorkSport Cold Pipe with 3.00 Inch Section

Figure 2: CorkSport Cold Pipe with 3.00 Inch Section

On top of the added volume, the larger diameter piping improves the flow through the throttle body because the throttle body has a 2.75 inch inlet. You wouldn’t put a 2.5 inch turbo inlet pipe on a turbo that has a 3 inch inlet would you? Nope, I didn’t think so. So why do that to your throttle body?

This can be seen in Figures 2 and 3 with the varying colors around and behind the throttle plate. The color graph shown with each image provides the air velocity for the different colors. In Figure 3, you can see there is more red and orange past the throttle plate when compared to Figure 2. The result of higher velocity flow is more turbulence which lowers efficiency through the throttle body.

Figure 3: Comparable CorkSport Cold Pipe with 2.50 Inch Section

So, if volume improves performance, then why isn’t the entire piping system 3.00 inch? At a certain point more volume becomes a performance degrade. This falls back to the pressure and volume compromise. The more volume you have , the longer it takes to build pressure. Smaller diameter piping makes up the rest of the kit, so the turbo can pressurize the system quickly while the engine is using the extra volume sitting directly in-front of the throttle body. By the time the extra volume is used up, the pressure has made it through the entire system. The combination of these two reduces turbo lag and improves throttle response. It’s safe to say that this is the best of both worlds.

But wait there’s more! Along with new piping, we are offering a large core kit with a crash bar. The crash bar retains all the necessary OEM hookup points for the radiator core support and the OEM tow point.


Figure 4: Assembled Large Core FMIC Kit with Crash Bar


Figure 4: Assembled Large Core FMIC Kit with Crash Bar: Under the Hood

The large core measures in at 23.25 inches wide, 11 inches tall, and 3 inches thick with 10mm runners for high thermal efficiency and a low pressure drop through the core. Below, Figure 5 and 6 show the temperature and pressure drop of the small core tested with a K04 turbocharger at 15psi target.

Figure 5: Multiple runs testing the small core temperature drop with the K04 turbocharger targeting 15psi.

Figure 6: Single run testing the small core pressure drop with the K04 turbocharger targeting 15psi.

Figure 6: Single run testing the small core pressure drop with the K04 turbocharger targeting 15psi.

The hotside boost air temperatures can reach upward of 250 degrees Fahrenheit, but the intercooler stays at a cool 110 degrees or less. You can see the average coldside temperature is steadily increasing, but this is typical of any intercooler run after run. Combine that with an average maximum pressure drop of 0.6psi, and you have a very effiecent intercooler.

That wraps up the new and improved CorkSport FMIC Kit for the 2010-2013 Mazdaspeed 3. Check it out online at corksport.com!

Dear Car Guy,

I was having a conversation the other day with some “Non-Car Guys” (NCGs) and a thought crossed my mind… that of course made me laugh out loud… because YES, I find myself hilarious.

I thought, “There are things Car Guys say that would be totally inappropriate for anyone else.”

Any Car Guy knows what I’m talking about. You probably come across a new one every time you talk to a NCG, but here are my top 8 things that could be misunderstood by the rest of the world, when a Car Guy says them:

1. When a Car Guy says he “needs meth”… it means something really different from the Breaking Bad kind.

Car Meth

2. When a Car Guy says, “I put my girl on a diet…” or “I’m cutting her weight down”… he’s not talking about his wife or girlfriend.

Weigh Station Problems

3. When a Car Guy says, “I need bigger rubbers…” He’s not ALWAYS referring to his manhood.

Car Guy Rubbers

4. When a Car Guy says, “I like the weight of my knob…” Again, he is (most likely) not referring to his manhood.

Mazda weighted shift knob

5. When a Car Guy says, “I’m rich…” He’s definitely not talking about his bank account—because we all know he’s spent his money on car parts.

Spent too much on Mazda parts

6. When a Car Guy says, “I gutted my cats…” It is safe to assume that he’s not a maniac or animal abuser… but just in case: downpipe.

Loud Down Pipe

7. When a Car Guy says, “I’ve been running lean…” He is most likely, not referring to his workout regimen.

Car Parts Diet

8. The trickiest one of all… when a Car Guy says, “He’s putting a straight pipe in her…” it is likely he could be referring to BOTH his car and his lady.

Putting in That Straight Pipe

Until next time Car Guy, stay safe, stay fast, stay happy…

Keep your Mazda looking good all summer with these tips from CorkSport.

As temperatures rise, your Mazda is going to feel the heat. With all of the road trips and picture perfect drives, you need to keep your baby looking good and driving well. We rounded up the top summer care tips that the CorkSport community submitted to us on Facebook and added in a few of our own.

Search for shade

The sun can damage your car’s paint job and interior materials. Keep your Mazda safe by parking in the shade or using a garage whenever possible. Quang Lam always keeps his Speed in the garage to prevent sun damage, and Brian Pinter recommends never washing your Mazda in the direct sunlight.

Get fresh fluids

Keep your Mazda running smooth during the hot summer months with fresh fluids in your coolant system. It will protect your engine and keep your AC cold as ice.

Check your oil

Oil is your car’s lifeblood. Regular oil changes are the cheapest way to extend the life of your Mazda and keep it performing at its best. Change your oil before your next big road trip or if it’s been longer than three months since your last change.

Give her a proper wash

A good wash keeps your Mazda looking good and preserves its paint.

This is crucial for keeping your Mazda looking good and preserving the paint. Christopher Horton says the number one tip for washing is to never go to a car wash or use the dirty brushes at self-serve car washes. Their brushes are notoriously dirty and poor quality; you’re just asking for scratches. Joey Acosta and Nick Svarens always use a two bucket system for washing. One for soap and one with clean water for rinsing. Timmy Figgatt and Jeremy Shea swear by microfiber towels to prevent scratches, streaks, and water spots.

Keep the interior fresh

Exterior shots are sexy but you spend most of your time inside your Mazda so don’t forget about keeping your interior clean. Matt Buzzell specifically uses vinyl conditioner to keep his interior pure and preserve its matte metallic finish. Kevin Stockman swears diaper wipes actually make a great interior cleaner for dust and dirt.

Maintain a sexy shine

Keep your Mazda shine with regular waxes and detailing.

Now that your interior is fresh and the exterior is washed, it’s time to get that sexy shine. Kiefer Westlund, a professional detailer, and John Lukis recommend regular waxing using Meguiar’s Ultimate Liquid Wax. Meguiar’s wax sells for $25 per bottle, which will last for many waxes. Kris Pena and Jeremy Brown are loyal to Chemical Guys for all of their Mazda care needs. For more tips on keeping your exterior shine, check out our blog post on how to keep that new Mazda sheen.

Now you’re ready to take on the hottest months of the summer performing well under the hood and looking good.




Who doesn’t love an awesome shot of a Mazdaspeed, rolling through lush green highways? How about a whole stockpile of those shots, new angles and stances every week?

A lot of us drive beautiful Mazdas, but only a few of us have the photographic gift (or photographer friends) to showcase them as they deserve. For the rest of us, we can just enjoy the sights on Instagram, which has tons and tons of Mazda accounts we love.

We showcase owners and their pics every day with a #CorkSport Pic of the Day, so be sure to use that hashtag on your best shots. Sometimes, though, we need to point you toward a whole account, like these 5 Mazda owners you should be following on Instagram.

1. Gabriel Manzanera

He swaps out his wheels sometimes to keep things fresh. But really, Gabriel’s ride always looks fresh:



2. Marty Gro

Does it cleaner than this? Bonus: Marty takes some great pics of his dog too.



3. Nick Pereira

If you’re ever in the mood for just a glimpse of a Mazda, Nick finds the best angles of his Mazda 3, showcasing just how good every part of the car looks. (Don’t worry: He takes some killer full body pics too.)



4. Kyle Cross

You’ll see more than just Mazdas on Kyle’s professional photography account, but we don’t mind when every shot looks so damn great.



5. Charles Villeneuve

Hailing from Canada, Charles is serious about mods—and takes some seriously great shots of his 2010 Mazdaspeed 3.



Who else, guys? Give us a follow at @CorkSport and direct us to some other great Mazda owners on Instagram.





As some of you may know already, CorkSport HQ made the move to a much larger and more functional building in January 2014. I think we can all agree that moving sucks and basically consumes your life for at least the month before and after the actual move. Well, I’m here to tell you it’s a hundred times worse when you are trying to move a business while still “keeping the doors open”. In the chaos of moving and getting the new location setup just right it’s easy to forget about the little yet important activities. So what better way to get back in the groove than a BBQ and Dyno Day to support the local community!

July 18th was the big day with 15 cars scheduled to get on the dyno, and another 35-45 cars planning to show up to watch the numbers! With everything set up and the burgers and dogs grilling away, people started to roll in by 12:30pm. The first car got on the dyno and the show began.

Dyno Testing Day

First, a bit about our dyno; it’s nicknamed “The Heartbreaker,” and oh so many hearts has it broken. The Tq/Hp curves look good, but it just reads low numbers. For example, a stock Mazdaspeed3 puts down a sad 190whp. Anyway, amongst the 15 Speed3s that planned to hit the dyno the mods varied from nearly stock to big turbo builds with lots of meth. There were quite a few Speeds in the 200-250whp range with a nice assortment of bolt-ons, a couple cars running a BNR or CS turbo in the 295-320whp range and then there is Justin England: a local out of Washington rocking a built block, GTX3071r at 34psi and tons of meth. He put down a very respectable 400wHp/365wTq on the heartbreaker dyno.

More Mazda Dyno Testing

Just to give you another reference point, we threw a 07’ Corvette on the dyno that also has high flow cylinder heads, intake & exhaust manifold, performance camshaft, and full exhaust system. He put down a mere 420wHp/380wTq…yup. Anyways, enough about our depressing dyno!

Along with the constant roar of WOT pulls there was plenty of food and drinks and even a raffle thanks to a handful of sponsors: Tuned by Nishan, Justin at Freektune, Damond Motorsports, James Barone Racing, and CorkSport.

Check out the images below!

Hot Pink Mazda Miata

Yes, that’s a pink Miata with a V8 that’s a daily driver drift car…it’s basically badass.

All-in-all it was great day! We had a blast, put down some numbers, and stuffed our bellies. What more can you ask for?! Big thanks to all the NATOR OR members and CS employees that made this day possible and to the sponsors that donated items for the raffle! This is what makes the Mazda community so great!
