New Mishimoto Intake R&D!
 

Hey guys,

We've started a new R&D project for a second intake system designed for the twins. Check out the progress of development on our blog or posted within this thread.

A New Mishimoto BRZ/FR-S Intake, Part 1: Reasoning and Prototyping
Another Intake?

Wait … Mishimoto already has an intake for the BRZ/FR-S. Why design a second one? As this question crosses your mind, we can provide a simple explanation.

We have had great success with our existing cold-air intake system for this chassis, and the feedback from our customer base has been fantastic. Here is a look at our current product.

Mishimoto performance cold-air intake

After listening to our customers both directly and through web forums, we concluded that a second intake design was necessary for a completely different set of customers. Here are a few plans for our new design.

• Engine-bay mounted, stock-appearing airbox setup
• Easy installation and filter servicing
• Fits with Mishimoto direct-fit oil cooler kit
• Provide power gains over stock intake system

Our current intake system locates the filter behind the bumper. This requires bumper removal for both installation and filter servicing. Although this location would provide a rather cold air charge and would be less likely to experience filter heat-soak, we do realize that some folks are not interested in the slightly longer installation or servicing process.

Additionally, due to space constraints, several aftermarket intake options (engine-bay mounted) are not exactly compatible with our direct-fit oil cooler kit. We wanted to be sure that both of these products would function together without issue.

And finally, power gains. As with any intake upgrade, one expects a bit of extra power and torque, as well as an improvement in engine sound.
Prototype Development

As with other projects, development for this intake starts with stripping away the stock intake system.

We decided to start our system by creating the piping that would route from the throttle body to the air filter. Because we would be keeping the filter within the engine bay, we planned to utilize the stock air duct that feeds the stock airbox.

So we took the necessary measurements and modeled a design in 3D. We then decided to test our new 3D printer to produce a functioning prototype to test fitting and airbox development.

Yes, our new printer does indeed print in Mishimoto orange. Pretty slick! You can also see that this setup places our filter directly in the path of airflow from the grille duct. Below is a straight-on shot of this pipe.

A few things to note about this piece. We are eliminating the noise generator and the intake resonator. A majority of 86 owners remove the sound generator, but we are confident that our customers will be pleases with our intake and with sound it produces, without the additional piping.

We are also utilizing our mass air filter (MAF) housing with an air straightener, both of which are included in our first intake kit. The air straightener helps promote laminar (smooth) airflow past the MAF sensor. This will provide the same drivability you will experience with the stock intake.

Last, we are also utilizing our oiled air filter. This unit provides greater flow and surface area compared to the stock paper filter, which should result in improved power output. This filter is fully serviceable and will not require replacement over time, unlike the stock filter.
Coming Up!

Check back next time for a look at our process for creating the intake box design!

Grimmspeed Intake 2.0

Perrin V2 first pic and Grimspeed V2? is the orange thing?

We need more turbo's and header's too!!!

Mishimoto doesn't really do headers/turbos...but I'm sure if they did they would kick ass!

With that said, they put in TONS of time, effort and testing in to ensure their products work the way they should!

I was quite impressed when they came to my work and explained their processes.

Also, Mishimoto is an AMERICAN company...

Subscribed!

yea who is Grimmspeed anyway? they sound korean

I don't know. Matt and Chase are good with numbers though so it makes sense.

good with numbers how?

they're amazing business people and competent engineers..

race =/= competency or skillset

"Engine-bay mounted, stock-appearing airbox setup" .. I wonder if it's not worth to reuse something from stock airbox/snorkel, for even more "stock" looks, lesser price.
For example, set of smart mounting of this filter within that box + replacement airtube. Will complete stock airbox replacement to similar looking one really net much gains above that? But surely will rise price, shipping dimensions/weight/shipping costs ..

Glad to see there's another company looking into air straighteners on the intake. I have seen them used in the dirt bike world for years to help improve low end throttle response. I have been curious to see if a company will make something similar to FMF's Snap. http://www.fmfracing.com/Products/Accessories/632
Just a simple design that slots into the intake tube before the throttle body. I've heard they make a small noticeable difference but have not ridden a bike before and after to know for sure.

I love the clean look of it. The stock air tube is so weird with all the ribs and such. The tube is a silicone type material I assume? And I wonder what the top of the box would look like. I know you guys are set on the square box shape but I think a round box would be different compared to all the others available like the Injen, and would have less disruption of the air around the filter because of the sharp corners of the box.

Keep going! Looking good!

Air straighteners on our MAF sensor and General design is necessary to provide accurate readings for the maf, not necessarily to provide more erm.. Throttle response
