May-June Event Wrap Up

I’ve attended quite a few events over the last two months, everything from a pre-release Mazda 2 measuring session in LA to the All Mazda Meet in Newburgh, NY. Take a look at where else we have been:

May 12th, MazdasNW

There was a really big turnout at the May monthly meet at NorthGate mall in Seattle. There was a huge range of vehicles, RX-7s, B series trucks, Mazda 3s, Mazda 6s, MX-6, etc. This meet was surprising simply in the quantity of people and cars. There were several notable vehicles at the meet. A really nice FD RX-7 showed up at the event, which was all built by the owner. The whole car was well thought out and looked amazing. There was a really nice B Series truck with quite a long list of modifications as well, which I liked.

May 19th, Mazda 2 Measuring Session.

For the first time ever Mazda put up a vehicle and let companies get a chance to look at a new model before it is released through what they call a SEMA measuring session. This gives companies like CorkSport a chance to get measurements and start getting parts built and ready to sell as soon as the car is available. We flew down to Irvine, CA to spend the day collecting information to make new parts. Mazda provided two cars to look at and get information from.

While we were in Irvine we stopped by Tuttle Click Mazda, a Mazda dealership that offers our CorkSport brand products. If you’re in the greater Irvine, CA area stop by and check them out!

Their parts department showroom was in the middle of a remodel for better product displays while we were visiting so we couldn’t check out their awesome CorkSport display. If you are in So Cal and want to pick up CorkSport products locally give George a call at 949 421 3200. He is the parts manager for Tuttle Click Mazda. They had a good selection of Mazdas on the lot including a Red 2010 Mazdaspeed 3 with powder coated wheels and no front plate.

June 9th, MazdasNW

The June MazdasNW monthly meet had a smaller turnout than usual due to the Junuary weather the NW was experiencing. Despite the threat of rain we trekked to Federal Way, WA to attend the meet. One lucky customer was able to have their CorkSport Mazdaspeed6 cat-back exhaust delivered, saving him quite a bit in shipping costs.

We also got a chance to do investigative work into the 2010 Mazdaspeed 3 as to why the factory keyless entry system was not working on our Project Mazdaspeed3. More details on that adventure can be seen in my blog post about it.

June 5th, OCC All Mazda Meet

One June 4th at 9:30pm Chris and I hopped on a plane headed to for Newark, NJ to attend the OCC Mazda Meet. The plane landed at 5:30am local time (Sleep?? What’s that?) and we jumped in our rental and headed north to Newburgh, NY. Heading up the freeway we got passed by a train of Mazdaspeed3s on their way to the meet.

The event didn’t officially start until 10am but people started showing up early. When we arrived at 7:30 people were already getting cars parked in the lot. Due to an unexpected surprise our parts we had shipped to the event via UPS did not arrive so we were limited on the parts we had crammed in our carry-on bags to show at the event. This was one of the bigger all Mazda non-rotary specific events which I have attended. The RSVP list had 532 people signed up and 273 vehicles. Here’s a few pictures from the event, there were lots of cool cars there.

June 19th, MazdasNW Summer BBQ

MazdasNW hosted their annual summertime BBQ in Carnation, WA at Tolt McDonald Park. MazdasNW provided the food, drink, and cooking (thanks!) for the BBQ. The weather was unusually kind to us and there was no rain all day.

In true MazdasNW style, a parts installation immediately took place. A CorkSport SRI was installed at the event on a Mazdaspeed 6.

Well, that’s it for events for the last two months. We have plenty more events lined up for the next 3 months, so stay tuned here for all the updates!


MazdasNW Meet 4/14

The April monthly meet for the MazdasNW was held at Godfather’s Pizza in Federal Way, Washington on April 14th. This was the first event this year where rain was not a threat. We had a great showing of Mazdas of all types present, Mazda 3s, Mazdaspeed 3s, RX-8s, etc.

The event also had a Mazda travelling flag present. The idea behind it is to take a picture of the flag and pass it along to other Mazda enthusiasts. You can see the first picture below. To see the progress of the flag check out the forum post on Mazdas247.

One of the local CorkSport customers showed off her custom purple anodized CorkSport Power Series Intake and other components. There was also an FC RX-7 equipped with the CorkSport Power Series Header and Exhaust.

With plenty of Mazdaspeed 3s at the event there was a chance to look at plenty of different cars with various levels of modifications. We took out the CorkSport 2010 Mazdaspeed 3 to the event. It also has enough cargo space for us to fit an RX-8 bumper which we delivered to a lucky customer.

It was great talking with everyone at the event and catching up on mods people have done to their Mazdas. I look forward to the next event.


MZR Turbo Inlets -Comparing Apples to Apples

There are a lot of factors that go into purchasing any part for your car, and a turbo inlet pipe is no different. With a wide variety of materials and configurations on the market, it can be a difficult decision.

I think the major discerning differences between metal and silicone are that silicone is an insulator, which is why there are claims that the silicone is a) quieter and b) less prone to heat soak. I’m not sure if a) is true to a consequential amount, haven’t done a dB comparison by any means…but I seriously doubt that b) is true either. All materials have thermal properties, all materials transmit thermal mass at different rates. You can deduce all sorts of theories as to how this effects the boost air temps, but I really doubt that there is any discernible power output or boost air temp difference between a silicone, aluminum or stainless inlet pipe from one pull to the next. These vehicles push enough air to fill an office cubicle through that pipe in the span of under a minute. Then they run that air into a turbocharger that superheats the air. It takes 3 degrees of inlet air temperature change to result in one degree of boost air temperature change with a stock intercooler based on thermocouple datalogging that I’ve done on a number of different cars (Speed6’s and 3’s). With air traveling through a tube at insane velocities (like lets say…60 meters per second…or better yet 134 miles per hour), I find it hard to believe that there is any major detriment to having the turbo inlet pipe made of a more thermally conductive material than another.

The reason you buy the pipe is so you get rid of the stock pipe, which sports an oh so stylish, effectively square profile that changes cross sectional area erratically and is made of plastic which is also pretty thermally benign. But that’s not where the power or quickening of spool up happens when you add the inlet -it’s the flow of the air and the smooth transition from the intake to your turbo that you want to optimize. Simple as that.

If it were my car, I’d get one that a) works reliably, b) has quality construction and c) has a reasonable price tag. I can’t point out any on the market that fail a) or b)…all are excellent from what I have seen. Ours is $89….because designing and manufacturing any piece of tubing and/or silicone doesn’t cost much. Period. It’s a pipe. Every turbo inlet pipe on the market is a pipe -with three pipes in factory locations connecting into it. A few have factory like brackets that attach to the valvecover, some don’t. Some are aluminum (CorkSport and RPMC), some are stainless (Protege Garage), some are silicone. They all do the same thing.

Our system certainly gives you a few options that you should be familiar with when purchasing . But the first thing to remark on is -our intake includes these parts. If you’re in the market for an intake, this information is of benefit to you, but if you really want a good deal on all of these bits, grab our Power Series Short Ram Intake for your MS3 or MS6 or CX-7.

So back to the configurable differences if you already own an intake and want to get a turbo inlet pipe to match. Our turbo inlet pipes have a few toggles: Valvecover breather (yes/no) and Recirculation Valve Port (yes/no). The valvecover breather is almost completely unnecessary if you have an aftermarket intake that is not made by us -as most intakes include this provision in the CAI pipe or the coupler. So that’s almost always going to be a ‘no’ unless there’s some other reason why you want an external intake vacuum source to plug into (catch can, etc). The other is the recirculation valve. If you have chosen to do a strictly vent to atmosphere configuration on your bypass valve (not necessarily recommended), you can choose this option and clean up your engine bay a bit.

The final dial on these is the silicone color – for the silicone coupler between the turbo and inlet pipe, as well as the valvecover breather and boost control solenoid lines. These are available in Red, Blue and Black. Finally, in the near future we will be offering one or more powdercoating options starting with black.

Any questions, leave us a comment or shoot me an email.


An Intake for Every Engine

It has become evident to us that a number of our customers want more ability to configure the color schemes and finish options on their intakes to match the look of their car or their personality.

Because of this, we have investigated the feasibility of making all of our intakes fully color and finish configurable and are planning a staged product roll out to facilitate this. A product rollout complete with actual hard dates that you can rely on.

Stage I: Black Silicone & Filter and Full Configurability.
December 14, 2009

So starting…well…now, we have begun this transition with the rollout of black silicone couplers and charcoal colored dry flow air filters on our Mazda3, Mazdaspeed3, Mazdaspeed6 and CX-7 intakes. This brings us to three silicone colors (red, blue, black) for the Turbocharged MZR 2.3 DISI engines and two silicone colors (blue, black) on the MZR 2.0 and 2.5 Naturally Aspirated engines for the 2010+ model year.

Another option included in the first stage release of our fully configurable intake system is full configurability of your intake on our website. If you want black silicone, black MAF Housing and blue filter, you can choose that. If you want a red filter and a blue silicone, go right ahead. We’ll build it on the fly. We have gone through a number of lean manufacturing steps that will allow us to be agile and build our kit contents on the fly and retain our same day shipping capability for all stocked color capabilities.

Stage II: Color Anodized MAF Housings.
February 10, 2010

In this stage we will be offering three additional MAF Housing colors (most likely Blue, Red, Gold) and two powdercoat colors of turbo inlet pipe, which will be determined by your requests and polls on a number of popular Mazda enthusiast forums. Due to smaller batch quantities on the anodizing and additional process steps, we’ll be offering these colors at a small premium.

Again, we will still allow you full configurability to an extremely granular level -if you want a Blue Filter, Gold MAF, Black Silicone and Black Powdercoated Turbo Inlet Pipe, we’ll do it. Seriously, if you want a Red Filter, Gold MAF, Blue Silicone and Black Turbo Inlet Pipe, we’ll do that too. And just like we have provided now, photos of these combinations will pop up as you configure them on our website.

Stage III: Full Custom Anodizing / Powder Coating and more.
March 15, 2010

First off we’ll be offering powdercoated turbo inlet pipes starting with a gloss black and working into a number of other color coating options.

Additionally, this stage will allow you to fully customize anodize your MAF Housing in as many colors as we have access to. If you want a full blacked out intake with an emerald green, dark purple or titanium bronze anodized MAF Housing, we’ll get it for you (again at a reasonable premium depending on interest and volume). We’ll do our best to do small runs and keep what we can on the shelves based on polls and interest. Have a specific powdercoating color? We can make it happen. We may also start anodizing inlet pipes (we’ll be switching 4043 to 5356 TIG filler rod for perfect anodizing results if we go that route).

Here’s an example of some of the anodizing colors we’ll have available:

We will also be evaluating silicone colors at this point -because we know some of you are dying for that Kawasaki Green Silicone with Purple MAF Housing to go along with your Bosozoku exhaust, zero offset wheels and stretched tires. Or maybe you just want a clean, all white intake to go along with your CWP Speed3. Honestly, we’ll have to hear from you on which direction to go, but I’m guessing white will be in demand.

There’s more…but if we told you, we’d have to kill you. We’re still aiming to keep this under wraps to some extent as we’ve got some really unique options on the table that we’re still getting samples of. As soon as our samples are in, we’ll be polling for interest and standard style options.

We’re doing as much as we can to provide the exact products you want, configured to your style and taste. To do so, we’re having to stretch our manufacturing agility and call on all of our resources through local machine shops and manufacturers to keep small batch parts on the shelves in a wide variety of options.

Again, tell us what YOU want to see on your car. Have a wild combination that you absolutely MUST HAVE for your car and willing to wait for it? We’ll be putting together a handful of case studies showing some of the more creative combinations for the roll out of the future options on these products.


CorkSport Dyno Day

Last Saturday at our CorkSport Swap Meet, we had a great turnout for the Dyno Testing. With 16 people signing up ahead of time and 5 signing up on site, we got some great runs in from a diverse group of participants. We even felt sorry for a handful of non-Mazdas and let them participate as well!


High horsepower of the day was Jason O’Neill with his ’01 Miata. Jay’s car made 393hp to the rear wheels with a brutal 368 ft lb of torque. A week earlier he had the motor out to diagnose some issues with the variable valve timing as well as try to get the head into the shop for new valve guides and seals and couldn’t make it in time so he threw it back in just to drive down to the event on a set of beefy drag radials. Later in the evening he ran an 11.51 at 124mph out at Portland International Raceway. Brutal. I’ll say this much, when a lightweight little Miata pushing 400+hp (it was uncharacteristically chilly out Saturday night) on a cold track makes a 1.6 second reaction time, it’s driver has had some practice. Hats off to Jay for his awesome car and sticky launch skills.

Close behind was an LS2 powered FD RX-7 that was unbelievably clean. The install was gorgeous, with little over 1000 miles on the clock since the swap, and the powerband was equally beautiful. Dropping an Earth shaking 300ft lb of torque at 1600RPM and following that up with a 45 degree horsepower curve topping out at 376hp, this car would be more adrenaline pumping fun than a barrel of monkeys in an AK-47 factory. And the owner’s passion for Mazdas goes way back…he bought an FD off the lot new in ’93 as well. While purists will wince at the addition of Chevy Power to one of the crown jewels of Mazda’s Rotary history, I would guess anyone who saw the meticulous install and the owners passion for making this an all around amazing car would give it a thumbs up. The drivetrain wasn’t the only amazing thing about the car – the suspension and bodywork were phenomenal as well.

We had a pair of Speed3’s and a Speed6 on the dyno as well, with high HP numbers in the high 260’s and high torque numbers in the high 290’s. The dyno runs on these cars are all over the map, preferencing torque on one run, horsepower on the next. One car ran 257HP w/ 296ft lb followed by a run of 269HP w/ 282ft lb. And I always thought the less the driver could effect the run the more consistent the output would be – not so with the MZR 2.3 DISI powered sedans.

The rest of the pool consisted of two FS Powered Mazdaspeed Protégés, a BP Turbo Powered Protégé, Four Miata’s and two eardrum scalding FB RX-7’s that both gave the LS2 a run for its money for smoothest powerband.

Whole playlist – wraps up with the RX-7 and the miata.

All in all it was a great day, and we had some good opportunities to talk shop and discuss opportunities for more power. The Seattle area group from came down and were able to meet up with more of the folks on the forum who are from the Portland Area. All in all, it became clear that a lot of these Mazda enthusiasts are hungry for opportunities to spend time discussing their wrenching projects and spending time with like minded people. I look forward to future opportunities like this. Thanks again for everyone who came out to the event…without such great participation, none of us would have had as much fun as we did.

P.S. If you have video of your car on our Dyno during the CorkSport Dyno Day and it’s not included in the above video playlist, fire over a copy for me and we’ll add it! Sorry for not getting all of the cars on video, I had a few different hats I was wearing and wasn’t able to get them all.
