Love your new Mazda 3 but find yourself missing some excitement? Already have our Short Ram Intake and out Strut Tower Bar? CS has come to help. We are proud to announce the CorkSport Axle Back Exhaust for 2019+ Mazda 3 & CX-30!

Help your engine breathe!

Add some much-needed volume to your 4th GEN and help the engine breathe while doing so. It’s a great balance of growl under hard acceleration, yet quiet while cruising, plus you get a nice visual boost to the back of your ride. Read on for full details, and be sure to check out the product video for sound clips! (Mazda3 pictured below is OE ride height. If you are looking for more low, check out our 4th Gen Mazda 3 Lowering Springs!)

A deep and great sound

The tone is deep with some nice growl to it that you’ll love to hear. Due to the unique, offset inlet flange, we ended up going with the single asymmetrical resonator for the best tone combined with drone elimination. We tested multiple resonator combinations before determining the single long resonator was the best setup.

The sound was not our only focus, however. We’ve increased the piping diameter to minimize flow restrictions in the exhaust. The piping diameter was increased from the OEM of 50-55mm (depending on where you measure) to 63.5mm (2.50 inch). The OEM muffler section has a lot of twists, turns, and flow restrictions to quiet down your Sky-G. The free-flowing resonator eliminates this flow restriction, and when combined with the larger piping, lets the 2.5 breathe better.

The sound and performance also come with a visual gain. Exhaust tips are increased in size up to 90mm to better fill in the bumper cutouts of the BP Mazda 3. Each tip is dual wall construction that uses a rotated slant cut design. This helps the tips follow the curve of the bumper just like the OEM tips. Each tip is finished off with a laser engraved CorkSport name badge for a nice detail.

The GEN4 Mazda 3 exhaust also allowed us to bring in a feature we have never had before adjustable tip length. Each tip is attached using a slip fitting and exhaust band clamp to provide secure and exhaust-leak-free performance.

Three different tip length options

This slip fitting gives you up to 10mm of length adjustment to really dial in the look you’re going for. That is not even the best part though! We are offering three different tip length options for you all to choose from: Mazda 3 Hatchback, Hatchback w/Appearance Kit, Sedan, and CX-30.

The sedan tip option is the longest in order to fit the longer rear end of the sedan models. While not intended you could put these on a hatchback if you’re into the “blast pipe” look.

Adjustable tip lengths

The Hatchback W/Appearance Kit tip option is the medium length tip. These are intended for hatchbacks equipped with Mazda’s factory Appearance Package and are also the optimal length for the CX-30. This offers an aggressive look to match the aggressive nature of the Mazda Aero Kit. These tips can also be used on a non-aero kit hatch, however, they would stick out too far for most people’s taste.

The Hatchback without the Aero Kit tip option is the shortest option and is intended for regular hatchbacks without the Mazda Aero Kit. You can also run these tips on hatches with the aero kit if you’re going for a more conservative look, but they tend to disappear in the bumper skirt.

Recipe to Make a 500 HP Mazdaspeed 3

400 Whp not enough for you and your Mazdaspeed3? 

Searching for more power for your speeds MZR engine? 

Are you building your DISI motor, and trying to figure out your next setup? Say no more… 

This next Mazdaspeed-focused blog is going to focus on making some big power numbers, and what it takes to get there. Now is the time to go beyond the scope of the 400-wheel horsepower to look at what it takes for 500 horsepower at the wheels. 

In our 400 WHP blog, this is not an all-inclusive guide and the only way to achieve these power levels… However, it’s something that’s been tried and tested for years and proven to be a reliable method of making the power you’re after. We are aiming to educate you in the best way to make the most out of your MZR engine.

Let’s get started 

With the MZR engine being out for over 10 years, it’s had a lot of time under the knife. We know how the engine responds to different airflow mods, tuning characteristics, fuel, etc.

We also know that 400 Whp is about the limit of the stock bottom end on the Mazdaspeed 3. If you have a Mazdaspeed 6, then you can assume it’d be a bit less given you have AWD and need to account for further drivetrain loss.

It is beyond this point that the motor is in danger and could potentially let go. Keep in mind that at 400 Whp you are nearly doubling OEM power output, and that’s a lot of strain on those pistons and rods that were never designed to endure that power long term.  If you are wanting to go beyond 400 Whp then you should know that you are also looking at the price tag of a Built motor.

What it takes to Make 500 Whp In Your Mazdaspeed
CorkSport

Now, if you are relatively new to this, and aren’t very familiar with the basic building blocks of the platform such as the Cobb Accessport, and Upgraded Fuel Pump Internals, then I invite you to read our 400 Whp Blog to build a good foundation. Do you feel you have a good understanding of what it takes to get to 400 Whp? Then you are ready to read on!

When you’re at a point in your build that you are seeking 500 Whp then it’s safe to say that you probably have gotten the more tedious stuff out of the way… You probably have about every bolt-on modification, and you understand what it’s like to work with a professional tuner.

That being said, let’s do a bit of a recap on the 400 Whp mods, so you have a good idea of where we need to go from here.

These are all the recommended/required mods to increase engine airflow and efficiency to make 400 WHP.

Basic Bolt Ons: (Less Expensive / easily removable parts )
Fuel Pump Internals
3.5” Intake (Requires ECU relocation or battery box)
Upgraded EBCS
Upgraded Map Sensor
Upgraded Downpipe
Upgraded Intercooler
Upgraded Catback Exhaust
Oil Catch Can

Advanced Bolt Ons: ( More expensive / more difficult to remove )
Upgraded Turbocharger
Upgraded Intake Manifold (Optional but Recommended)
Upgraded Exhaust Manifold (Optional but Recommended)

Fuel:

Stock Fueling on Pump Gas usually nets around 330-350 Whp depending on octane and gas quality.

Stock Fueling on E85 blend fuel usually nets around 370-390 Whp depending on Tune aggression and also Quality of the gas and E85.

With Aux fueling such as port fuel, or methanol you can easily bump up over the 400 Whp mark and beyond. (I’ll get into the differences more in a bit)

Putting down 500 Whp pretty much requires many of the same mods that 400 Whp does, BUT the primary game changers are the Advanced Bolt On’s and Fuel.

(If you’d like to refresh your memory on the basic bolt-ons and how they affect your Mazda please refer to the 400 Whp blog.)

I’m ready for more POWAHH

In the grand scheme of things, making the 400whp is relatively easy and affordable considering it can be done on the stock block. With bolt on parts, fuel, and a tune you can easily hit that number. But as soon as you want to make more, you’re looking at a built engine, as previously mentioned, And that’s a whole new can of worms.

So, what’s all involved in a built motor? That’s a bit of an open-ended question as there are so many variables to take into consideration. However, “built” engines usually contain forged pistons and rods with upgraded bearings to handle more abuse. From there, the complexity increases as you get into port work, cams, etc. I will touch on that a bit more later. 

Fortunately for you, most engine builders have their entry level engine ready to handle 500 wheel horsepower and it’s a pretty basic build that features stronger internals. But, the tedious stuff like port work is usually reserved for the higher tier engines that are usually built for more power.

I won’t get into the engine building side of things, as that could turn into a whole other tangent. But you can assume that a built motor may cost you anywhere from 5k and up dependent on the level of motor you go with. From there we can start piecing together our 500 Whp build.

Let’s Talk TURBO’S (Crowd Cheers) 

The turbo is the heart and soul of the Zoom-Zoom, so it seems like a suitable place to start.

CST5 Turbo Upgrade – 2006-2013 DISI MZR

As we know, the CST4 is happy up to around 400+ Whp. Which is why it was the recommended turbo in the 400whp blog. But now we are ready to take a step up to the CST5 Turbo for the Mazdaspeed which is happy up to… You guessed it! 500+ WHP. With the ability to hit 20 PSI by 3500-3600 RPM and Carry out 30 PSI it really packs a punch for its size. You may be needing to upgrade your intake to pair to the T5, I’d recommend our Power Series 3.5” Intake I mentioned earlier. It will come with the 4” coupler required to mate up to the turbo.

The turbo is available with an internal gate, or an External Gate so you can choose what works best for you. Both options can hit the same power numbers.

Let’s Talk Fuel

What it takes to Make 500 Whp In Your Mazdaspeed
HPFP System

“What options do I have for bigger injectors?”

At CorkSport I get this question rather often. Unfortunately, I must tell them “There aren’t any”

Without going too off topic here I will explain why.

Our cars feature a Direct Injection fuel system or DI… And by today’s standards, it’s a bit primitive. The MZR DISI was one of the first pioneers of modern DI, which is probably why the OEM high-pressure fuel pump can’t even sustain the full potential of the factory injectors. Don’t worry, the CorkSport Fuel Pump internals fixes that problem.

Port Injection is simple and easy to maintain. It works by spraying low pressure fuel into the intake runner where it atomizes in the air stream before entering the combustion chamber.  For car guys, it’s fantastic and easy to swap out injectors when you are ready for more fuel.

Direct Injection takes a whole new approach. Instead of the fuel going in through the intake manifold, it goes DIRECTLY into the combustion chamber.

In order to overcome the force of compression, the fuel must be highly pressurized in order to atomize correctly. It also must deliver more volume in a shorter amount of time. This is why your Mazdaspeed has a high-pressure fuel pump. 

This causes a whole lot of complications for injector developers because things like fuel pressure also become a huge variable when attempting to create a larger Direct Injector. The bigger the hole on the injector, the more fuel pressure is required to create adequate atomization. Combining that with the rarity, and size of the Mazdaspeed platform, it’s just not worth it for any manufacturer to develop one.

So, what’s the solution to getting more fuel? Well… As previously mentioned, you pretty much have 2 choices Port Injection or Methanol. Since both of these are considered Auxiliary fueling, they are controlled by separate controllers, unless you want to ball out and get a Motec ECU that can control the OEM engine systems, as well as your port fuel.

Choosing which system, you want to go with solely depends on your power goals, and how much money you have to spend. Those 2 factors are pretty much the only question you need to ask yourself.

What it takes to Make 500 Whp In Your Mazdaspeed
Leo dropping that cash on a port Injection fuel system

Methanol – Cheap and simple 

Port Injection – Expensive and Reliable 

You must remember that the OEM fuel system, even with E85 in your tank is only good up to around 370-390 WHP. So, everything beyond that is supported by your AUX fueling. If your extra fuel system stops spraying for any reason, that could lead to catastrophic damage depending on how much you’re relying on it. When you’re just trying to nudge over the 400 whp mark on a CST4 or CST5 then Methanol is usually fine in my opinion. But beyond that, I’d be concerned with the reliability aspect.

When you have a properly set up port fuel kit (Manifold with fuel rail required) it behaves almost as if there is no AUX fueling system. This is especially the case when you have it all integrated into your factory gas tank and don’t need to fill up a separate cell. A quality Port Fuel Kit is pretty full-proof.

You’ll have to make the decision that’s best for you, but I’d recommend a port fuel kit to support 500 Whp, vs a heavy spraying methanol kit.

Let’s Talk Manifolds 

Manifolds are responsible for transferring all the air in and out of the motor from their respective cylinder. This job is an important one as it needs to distribute the gases as evenly as possible. The more even the flow, the better the performance!

On the Mazdaspeed Platform, the OEM intake manifold is known to be the bigger restriction over its exhaust counterpart. With very unequal flow distribution across the 4 runners, it has been proven not only to restrict power but also cause premature wear and tear on cylinder #3; here’s why.

This is caused by “over-feeding” air to #3 in comparison to the other cylinders. Over time this #3 is actively running leaner than its counterparts which is why it’s been deemed the most common cylinder to blow if an engine does give way.

It is because of this, that I always recommend a CorkSport intake manifold for even stock power levels. It may not be required to make 500 Whp, since you can essentially just turn up the boost to counteract the restriction. But in the name of reliability and efficiency, you should always try to help your engine breathe with the most minimal effort while also helping it maintain its health.

CS manifolds, FMIC, and 3.5” intake in picture

The OEM Exhaust manifold may not be as bad as the intake manifold, but it’s still not ideal, especially at this power level. A performance exhaust manifold needs to be designed with exhaust scavenging in mind. 

Exhaust scavenging is a very cool effect. The exhaust gases leaving the combustion chamber travel out the individual runners and enter the collector. It’s at this point that it creates a vacuum-like effect on the runners, assisting the exhaust gases to escape from the other cylinders. This constant scavenging helps improve exhaust flow dramatically, especially when you start making power over 400 Whp.

You can learn more about exhaust Scavenging in our Blog that dives deep into it and shows examples comparing our Exhaust Manifold to OEM!

CS Exhaust Manifold vs The OEM Manifold

When you replace both the Intake and Exhaust Manifolds with a performance unit you are drastically helping your motor improve its efficiency, which can mean 3 things.

1. Make the same power on less boost.
2. Make more power on the same boost.
3. Make Way more power on way more boost. 

When you have to push your car less to make the power you want, reliability improves, and it also needs more room on the table for when you want to make even more power later on.  That leads us to our next topic, Efficiency Mods.

The Cherry On Top 

With a built motor, full bolt-ons, fuel, and a big enough turbo you can easily hit 500 whp.

However, efficiency mods such as Camshafts or Throttle Body will help you make more power easier, or really push the limits of your turbo by improving its ability to perform.

Our CS Camshafts are ideal when you start getting into this power range. It helps with everything from turbo spool, midrange power, and top end. Even on K04 powered speed 3’s / 6’s our cams netted around 20 Whp. You can imagine the kind of exponential improvements it can make as you move up in power.

Camshafts for Mazaspeed

That being said, if you’re already having a motor built, or you happen to be going inside your motor, its not a bad idea at all to toss these cams in. They will only help you, and if anything, help your car to not need to work so hard when you’re pushing its limits.

Performance throttle body for Mazdaspeed
Performance Throttle Body for 2006-2013 DISI MZR Mazdaspeed

To top that off something like our CorkSport Throttle Body has been proven to make more horsepower and flow 33% more CFM than the OEM unit. Up until recently, no other throttle body has been a viable option due to drivability issues. But CS now offers a drop in plug and play unit that doesn’t come with the problems and utilizes OEM ECU logic to function. Modifications like the throttle body are the awesome little bonuses you can do to help the car hit that 500 Whp mark even easier.

Let’s Recap

So, to cover everything that we’ve learned:
This is what we recommend to achieve 500 WHP

1. Built Motor with upgraded Cam Shafts
2. Auxiliary Fueling
3. Full Bolt-Ons, CS Throttle Body recommended.
4. CST5 Turbocharger
5. Manifolds

We hope you enjoyed reading this blog, and now have a better understanding of the details that go into making 500 whp. Next, we will be reviewing the in’s and out’s of 600 whp!

Mazdaslow to Mazdaspeed

Let me take you to an extraordinarily dull time in my life, the last time I started my Mazdaspeed when it was still stock.

September 14th, 2018 was a beautiful September day in Washington. I started my car at 6:45 am, just like every other weekday. The Speed3 burbled to life, but it was relatively quiet, flat, and a bit uninteresting. No one knew I was leaving for work – I wasn’t shaking any windows, but that was going to change.

CorkSport mod budget. Employee incentive.
At CorkSport

Once I arrived at work and spread some Friday cheer, I settled in. Almost immediately, I could feel the pile of parts in the corner behind my desk, glaring at the back of my head. I thought to myself, “Don’t turn around – focus damn it!” The day had finally come – install day. Thankfully with our awesome half-day Fridays, I was out of the office and on my way to Brett’s house before 12:30 pm. 

After we loaded up Brett’s Rodeo with a load of parts, we set sail to our destination, a place where many tears have been shed, knuckles have been busted, and where dreams have come true; Brett’s garage. Every tool you’ve ever needed and gadgets you didn’t know existed. There were even a few specialty items present, that if he didn’t have quite frankly, this couldn’t have happened.

We started with thorough degreasing of the engine bay and setting up the essential supplies- because what is an install day without beer and snacks! Once the car has cooled down, I started with taking out the battery box, intake, and intercooler; and then the fun really started. I’ve read the horror stories, I’ve watched the videos, and I thought I spent enough time mentally preparing myself for what was about to come – I was wrong.

The Downpipe

We all know about the Mazdaspeed downpipe on our cars. The devil engineered the placement of this thing, and he had his minions tighten the bolts. There isn’t enough PB blaster in the world to help the corrosion and excessive heat that these bolts withstand. We got the first one out with little to no issue, but it just got progressively harder from there. It was only a matter of time before rounding off the edges of that last bolt. Thankfully Brett has an extractor tool that we hammered on there, and with the small act of god, it was successfully extracted.

My experience with removing the downpipe from the exhaust, as is everyone’s experience, was different. Mine was influenced by the previous owner adding a 2.5″ resonated exhaust on it from the second cat back. The downpipe didn’t want to come out until I wiggled a pry bar in between the flange and put Brett’s Caliper spreader in there (again tools I didn’t even know I needed) and applied sheer grunt force. I got the flange to bend, and after learning a few new choice words, we got it out. By this time, it was 11:30 pm, and we still had a few other things to unbolt before the exhaust came out. Instead of using power tools and waking every neighbor up in a two-block radius, we called it a night.

The Morning After

After some much-needed coffee, we made it back from the hardware store (replaced the downpipe nut from hell) it’s time to party. We started with sliding in my new downpipe with the High flow Cat what a breeze compared to taking it out. Next came my intake, I went with the 3.5″ so I don’t have to buy another one when I finally go with our CorkSport CST4 turbo. Still might go with the new CST5. Then I put in my ECU Relocation Box, and I have to say, what a clean looking piece to have in your engine bay! 

CorkSport Mazdaspeed engine bay parts TMIC with Intake, battery box, turbo
Mazdaspeed 3 TMIC Top Mount Intercooler

We changed out the OEM spark plugs for some NGK 6510 gapped to .026 and started to put on my new TMIC that is rated up to 450WHP after we got the TMIC it was time to put on my shiny new boost tubes Engine bay= Complete.

Now time to get underneath and put on my highly anticipated Non-Resonated Cat-Back exhaust and my Stage II RMM. Goodbye, torque steer! Once we had the exhaust mostly in place, I realized if I didn’t have the CS exhaust hangers I would have been in trouble. The person before me had his exhaust welded quite poorly in place of the hangers, and I didn’t have an option to use my OEM ones. 

Moment of Truth

After everything was double-checked and rechecked, it was time for the moment of truth. I hooked up my battery, I flashed my new tune from Erik Bjork at Drama Tune, and now it was Go Time! I will say hearing my car make those sweet sounds was one of the best moments of my life. I’ve been waiting for this moment since I purchased my car, and it was one of the most surreal experiences I have ever had.

We let the car run for a few minutes and checked to make sure I didn’t have any leaks, and then we headed out for a test drive.

In the immortal words of George Takei “Oh My!”

That was my thought, EVEN on just a base map. My car felt and sounded 1000% different than before. The intake was amplifying fun new mechanical noises – like I was hearing my turbo and BOV dance for the first time. The crackle from the exhaust on a hard 2nd to 3rd upshift was intoxicating, all the while my RMM putting in work to make sure I didn’t torque steer into someone’s front lawn. What an experience! I would even call this life-changing for me. The funny part of the story is that I wasn’t planning on buying all these items at once – true intentions of a foolish car enthusiast. Thankfully for me, I have a fantastic career within CorkSport and have a great friend who helped me make my dreams come true. Who wants a stock car when you work for the number one place in the world for Mazda Performance, not this guy?

Performance Parts for the 4th Gen Mazda 3

Today we are going to lay it all out; we are going to tell you about what we are working on for your Mazda 3 and WE ARE EXCITED!  Who are we?  If you don’t know already, we are CorkSport Mazda Performance based out of Vancouver, Washington.  We are the number one Performance Aftermarket Mazda Parts Company and we have set our sights on the 4th Generation Mazda 3.

Below are the first projects we are developing for the 4th Gen Mazda 3 and CX30.  Engine performance, suspension performance, and styling are all covered here and we are closer to launch than you may realize.  Sit back and enjoy, there’s a lot here and we want you to see it all. 

White 4th Gen Mazda 3
CorkSport – Lowered on CS Springs

One of the most sought-after and anticipated performance items for the 2019+ Mazda 3 are the CorkSport Lowering Springs.   The CS springs provide the most aggressive drop on the market today while providing a sporty and comfortable ride for daily driver use.  With that, we have confirmed fitment on FWD manual transmission hatch and AWD automatic transmission sedan.  We found that the Auto AWD Sedan rides just slightly lower, but is still within proper ride height for suspension function.

We design our springs with more than just looks in mind (but they do look great).  Spring rates and suspension frequency are critical to performance and comfort.  With that being said we increased the front spring rate 52% and rear rate 40% based on the OEM 2019 FWD Hatch MT springs.

Now if you’re looking at the images and thinking “Damn those wheels look good” then you are correct and we agree; they look amazing and fit the car and CorkSport springs perfectly.  

Here are the specs: Advan RS 19×8.5 +38 with 235/35 Kumhos.  We have just the slightest rub on the inner fender on large bumps.  Besides that they are perfect and you can have this setup too!

Next up is the CorkSport Axle-Back Exhaust.  Off the showroom floor, the Mazda 3 is ghostly quiet which is pretty disappointing. Our goal with the Performance Axle-Back Exhaust is a noticeable but mellow tone that you can enjoy every single day; gents this is Wife/Girlfriend approved. 

Red Mazda 3 Sedan
CorkSport – Using OEM Springs

We are proud to announce that will we be supporting multiple models on launch.  We have confirmed the Sedan, Hatch, Hatch w/Aero Package, and the CX-30.   Along with that we have confirmed fitment for both FWD and AWD models for all cars listed.  

See all of our Strut Bars

Look closely, there are a couple new products in this engine bay…long in development is the Short Ram Intake System which replaces the OEM airbox with a high flow dry element filter, billet aluminum MAF housing, 4-ply silicone coupler, and stainless steel T-bolt clamps.  

Upon launch we will be offering various color combinations between Black, Red, and Blue.  You can see them below.   

Mazda 3 Short Ram Intake System
See all of our Intakes

In our testing we have seen repeatable 5whp gains at peak with a nice increase across the RPM range.  Street driving our butt dyno agrees with crisp throttle response and a lovely intake induction noise.  The combination of induction noises, exhaust note, and sporty feedback from the sport springs really turns the Mazda 3 from an A-to-B car to a great enthusiast hot hatch.

The other project sitting in the engine bay is the CorkSport Front Strut Brace.  Bracing the strut towers to each other improves chassis stiffness and reduces suspension complicity.  This results in increased driver feedback and thus a better driving experience.  The powder coated steel brackets and polished aluminum cross bar add a nice loot to the engine bay.  

Rear sway bars designed for the 2019 Mazda 3
Click to See all of our Swaybars

Lastly, and still in development, are the rear sway bars for the FWD and AWD 4th Gen Mazda 3.  This project has been interesting because of the new torsion beam rear suspension found on the 4th Gen Mazda 3.  It’s interesting because there is no factory equipped sway bar.  Instead of just developing a larger rear sway bar, we are developing a sway bar from scratch along with the attachment methods.  

You also notice that there are two different bars in the image.  This is because the AWD and FWD torsion beams are different due to the AWD drivetrain.  Long story short, we are developing a RSB for each drivetrain specifically because that’s the correct way to do it.  

Wow, that was a lot, and trust me there is more we are investigating, but we can’t let ALL the secrets out yet.  We would love to know what products you would like CorkSport to develop for the 2019+ Mazda 3 platform, you can do so right here by Submitting a Product Idea.  

Also, we love sharing with the community directly and have been doing so in these groups.  If you don’t know about them then check them out and join for more info.

Barett’s 1/2 Mile Mazdaspeed 3 Build – Part 1

Hey Everyone, if you don’t know me already I’m the engineering manager at CorkSport Performance & @Halfmilespeed3.  I want to make a formal greeting and invite you to follow along as I take the next huge step with my personal build.  I drive a 2009 Mazdaspeed 3 that has been through many iterations.  I bought it nearly 6 years ago and have since used it in excess to support CorkSport R&D.  Hundreds if not thousands of passes on the dyno with so many parts…it’s been a beaten test mule.  The time has come to set a focus.

2007-2009 Mazdaspeed 3 Crashbar

Now, with the 4th engine going in it, I’m setting the build focus for ½ Mile Drag Racing.  Power, Aero, and some “Mad Scientist” R&D is going into this build.  (see WTF is THAT)

My goals are 700whp on the CST6 stock flange (with Will @ PD Tuning giving it the sauce) and 180mph in the standing ½ mile.  I plan to play in the 1320, but half mile is the focus.  My first event was going to be Never Lift @ Coalinga Munical Airport in Late March, but with recent events, this was canceled and a new date has not been set.  Fingers crossed the country gets through this and the next events hosted by Shift S3ctor Airstrip Attack in June and November hold.

Back to the build…I know that pushing a Mazdaspeed through the air at 180mph is a lofty goal and that physics are against me.  With the help and advice of Aaron O’neal @ English Racing I am exploring high-speed aero design.

The primary goal is stability at high speed.  I want to be safe in this type of racing so I need to do what I can to make the car stable and predictable at speed.  This means I need the car to cut through the air as smoothly as possible, and if possible, generate downforce. 

To do this I’ve made a prototype drag wing (which I will share more detail on in a later blog) per the advice of Aaron and my research.  This wing is two feet long at the top! And with the closed sides, this should reduce the amount of lift generated at the back of the car.

There is still a lot more work to do here but you get the idea so far.

Upfront I am still very much in the conceptual phase of design.  Nearly the whole front bumper will be sealed off with a single sheet of ABS plastic formed to the front of the car.  The only opening will be a rectangle about the size of the intercooler for cooling airflow.  I also plan to build a chassis mounted splitter.  The red parts in the image above are the one-off brackets I designed to mount the splitter to the chassis and still be able to adjust the height (Again I’ll share more detail in future blogs as the prototype comes together).

The other less intuitive aero bit I’m doing on the front of the Speed is hood venting.  Thanks to Jonathan Castro @ JC Speedworks for the hood vent I’m able to kill two birds with one stone here.  If you’ve done any type of racing you know heat is a killer and must be managed.  With this hood vent, I am both evacuating any high-pressure air build up in the engine bay and promoting more efficient airflow through the intercooler and radiator. 

With the 300 miles I’ve put on the car, I can already see a huge difference in normal operating temps.  Maybe more vents are in the works? 😉 Oh and shout out to @mz_rawr (Aaron Maves) for cutting holes in my hood.

In the process of getting the engine and transmission together, I wanted to fix a 2nd gear drop out issue I had.  Over a weekend @thatonepnwguy (Bryce Peterson) and I split my transmission and replaced the shift forks.  We certainly did it the wrong way and had to chase some balls around and get them back into their respective locations; despite all that, don’t be afraid to tear into things and learn the hard way. 

How To Achieve 400 WHP In Your Mazdaspeed Blog

The powerplant made it in the car and is running great.  Right now I’ve got about 300 miles on the engine.  I’ve been working out some little details with heat management and setup of the Vacuum Pump (WTF is THAT).  I am just now starting to do logs and tuning with Will Dawson at Purple Drank Tuning.  With these goals, I still intend to keep the car street legal and driven on a nearly daily basis (I wish you could see the stares I get from people).  I’m putting this out to all of you as an invite to follow along with the build on Instagram @halfmilespeed3.  All the inside info and goodies are there for you to see along with @corksport for other stories and build updates.  I’m stoked for this season and to explore a racing series that has largely been untouched by the Mazdaspeed community.  I will be finding limits and new challenges for the platform that I hope to overcome.
