2010 MS3 Cold Air Box Prototype Testing

Just got done doing the initial testing on our prototype cold air box for the 2010 MS3. We put a box together that is a bit different from our existing boxes on the previous generation vehicles.

Previously, we closed out the entire front corner of the engine compartment with the box. With the 2010, the fuse block is in that vicinity and there’s a large wiring harness that crosses over the boundary region where we profiled for the box edge. We were also curious to see if we could build an efficient box that would allow our customers to retain access to the headlight assembly and fuse block for quick bulb and fuse changes.

We’ve done three extended runs on the 2010 MS3 with Cold Air Box and come to some interesting conclusions. In previous tests on the MS3 and MS6, we found that the dynamic pressure zones under the hood of the vehicle can be counter-intuitive as to the areas that provide cold air and/or allow ingress of hot underhood air into the filter.

The first run with a box that had multiple areas of access to the hot zones in the engine compartment was surprisingly successful. On a 51F day, we hit a 40+ degree max differential between underhood (immediately outside the box) and filter surface temperatures. Not bad! On the hotter days (86F) this summer when we were running the tests on our MS6 we hit around 35 degrees max thermal delta.

The next test we performed was with a number of the holes and reliefs in the box (clearance around the silicone coupler, closeout to the headlight assembly and a clearance hole for the recirculation valve) shored up and sealed off, we took the car out for another run this morning (waiting specifically until the outside air temp hit 51 again). We were hoping to get to ambient air temperature, which would have been a 60 degree temperature differential. Just like the MS6 tests last year, we got close, but stopped short at 5 degrees above ambient for a maximum in the box to out of the box temperature differential of 51 degrees F.

Wanting to see that 5F disappear, we went berserk and busted out our mad Scotch packing tape fabrication skills and sealed the entire box off to body and inner fenderwell. Absolutely no change. Which was honestly a relief. The simpler we are able to make the design, the more margin we have to spend on the aesthetic design and provide our customers with design that looks as seamless as possible with the factory underhood environment. Justin did a great job with the initial mockup, matching the contour of the factory intercooler cover, but we’ve got a ways to go. Next step is to pull the box out, bust out the bondo and shaping tools to fine tune the look and feel of the box. Meanwhile I’ll be chucking some delrin up in the lathe to knock out some fittings and fasteners as well as fabricating some finished brackets to ensure a solid fit with the OEM airbox grommets, battery box and radiator crossmember.

Finally, I need to make some phone calls and get some quotes on a pre-preg Carbon Fiber lid as well as a Dry Carbon lid. We’d love to make this a reality, but the numbers confirm or deny the reality of that option.

I know you’ve all waited a long time for this and it’s been for good reason -we want to raise the bar with this design and we’re excited to make it a reality.

New Chassis Brace Designs!

About a month or so back, John and I decided to take on a new project. We managed to stuff 4 different chassis braces in the hatch of our 2010 Speed3…simultaneously. We have since had some time to test the various mount points back there to see where the best solutions would be provided. Our goal is to deliver a few different bars that can be mixed and matched and then deliver a secondary stage that will tie the primary bars together.

With that in mind, we know you love your trunk space and functionality on your hatchbacks and pass-through options on your sedans… So we have some tricks up our sleeve to make sure that your significant others will still be able to take a boosted trip to IKEA without complaining about the birdcage in the trunk getting in the way of that NORDANÖ Armchair and VÄRDE Kitchen Cabinet.

Since our initial investment into the design of these systems and testing of them, we have come up with a few conclusions that have lead to some development of a final product that we’re hoping to have out in the next month or two. We looked at a number of elements of the design: bar material for optimal structural integrity, options for quick disconnects that provide solid mounting points and finally -the look that matches our existing products for the 2010 vehicles.

In order to do this, we wiped the drawing board clean and started with a 1″ solid aluminum section of bar stock, black anodized with a laser etched CorkSport logo. We then evaluated the bracketing systems and methods of making solid, quick disconnect systems that will prevent chassis flex, yet provide our customers the ease of removal on the fly. I used to work in Aircraft, and whenever we wanted to make systems quickly removable we would use aircraft seat track systems with quick latching lugs and push-button quick release pins that are reliable and can handle a substantial load.

In order to accommodate these features, our designs require a higher level of accuracy and tolerance control than we are afforded with our welded style one-piece bars. Which means the brackets and the endlinks have to adhere to a high accuracy in their diameter and their overall thickness so that the grip length of the quick release pins will hold the system together accurately.

Mind you, using hardware like this to provide the best options to our customers are not by any means inexpensive. But that forces us to use all of the tools we have to minimize the cost of our designs simply through their manufacturability and through the process of minimizing part counts and simplifying design and build processes.

What we end up with are chassis braces that you can disconnect on the fly without any specialized tools. We’re still working on ways to make the integration of these systems appear as though they were factory solutions, because we know when you pop the hatch on your brand new Mazda3 or Mazdaspeed3, your friends and coworkers don’t expect to see your carpet and interior panels hacked up with a load of scaffolding occupying what should be usable trunk space….

The best part is that from the exterior of the vehicle, to the under-hood to the hatch and interior, you’ll find a consistent product line that expresses a level of quality commensurate with your 2010 Mazda. We look forward to sharing some of our other new designs in the near future. And we can’t wait to discuss some new ideas and directions with you. Keep in touch with us if you have any comments or ideas about product development or the direction we are taking with our designs.

2010 MazdaSpeed 3 Downpipe Update

We have had some interesting times with the development of our downpipe for the 2010 Mazdaspeed3. Downpipes on the 1st Gen MS3 have historically been a bit of a puzzle to work around the dynamics of the factory computer’s expectations for what should be seen at the two oxygen sensors on the upstream and downstream side of the factory catalyst. From our research, customer feedback and experience, our designs are able to avoid throwing a check engine light on first generation DISI equipped vehicles. Other manufacturers of downpipes are hit and miss depending on the manufacturer, with some throwing the occasional random CEL for slow response time and others being more pervasive.

The 2010 model is more finicky. Initially, we faced some check engine lights resulting from the vehicle not seeing what it expected at the secondary oxygen sensor, but we made some adjustments to the O2 sensor and have thus far run our test car for ~30 warmup cycles without any sign of a CEL. The 2010 Mazdaspeed3 runs a different algorithm than the 2007-2009 models and this results in a little less tolerance to radical changes in downpipe design.

That being said, the codes we initially were getting were based on a slow response time of the O2 sensor -a code that one of our local customers was getting on his bone stock 2010. We have had our downpipe on the car for nearly three months now. We’re proceeding with caution and planning on getting a handful of downpipes out into the public on a limited release to test the waters and ensure that the design will be free of any CEL activity for all of our customers and not just the single test case of our shop 2010.

If you’ve been chomping at the bit to get ahold of our downpipe, drop Derrick an email or call us at 360-260-2675 and we’ll get one out to you. We would also be very interested in getting one of these out to someone in our local area with an otherwise stock vehicle so that we can do some before/after dyno testing. We’ve done the staged dyno on our 2010, now we’d like to do a run with the downpipe to see how well it performs on its own.

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 ~$120….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 rollout 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, Mazda 6, CX-7, CX-30, and CX-50 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 powder coat 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 reconfigurability 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 powder-coated 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 powder coating 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 Mazdaspeed 3. 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.
