Injen Technology Intake and Exhaust (with dyno and pics)
 

Here is the finished intake, available in Polished and 'Wrinkle Black'.

Here is the dyno data from the intake, with 3rd and 4th gear pulls:

The exhaust isn't quite ready; they need to spend a couple more days working on the fitment and such.

EDIT: Moved from first to second post to put dyno and product pictures first.

So, my beautiful Delilah is down at Injen Technology again all week. The intake should be finalized this week, which means that units could start rolling out to distributors by the end of the month. Don’t quote me on this, but that sounds like a reasonable expectation.

The FR-S and BRZ are extremely efficient even at high intake temperatures, which is both really cool for us and really awkward for manufacturers, as the typical ‘colder and denser is better’ doesn’t necessarily show the gains, un-tuned, that you would expect of the car. I am not an automotive engineer, so I understood probably half of the discussion, but I know what I can hear and feel from the unit so far, and they definitely got something right. Response is smoother across the board, and once you pass about 2/5ths throttle, the intake noise is throaty and muscular. I LOVE cracking open the throttle now.

The intake doesn’t have a port for the sound tube, so a delete will be necessary. They did a ‘half delete’ on mine, keeping the tube to the compartment, but removing the port from the intake. I’ll show some pictures of that a bit later, when I get the car back.

The main reason my BRZ is there, though, is so they can finish the exhaust system. The catback is ~70% done, and is GORGEOUS. The merge collector and dual muffler setup ends in 4” polished slightly slant-cut resonated tips, and there is no drone at all. The tips perfectly fill out the cutouts for them in the car, and I’m really wondering how it would look with the OEM rear diffuser. Hmmm…

From the back, the exhaust looks menacing and clean. Injen is still deciding what to do for the downpipe and midpipe area; costs and gains need to be calculated. I really hope to have dyno graphs, pictures, and a couple videos by the end of the week. I am also hoping to have a duplicate prototype exhaust installed so I can do some real world road testing and show it off around town. :)

Rather than recount the whole company history for those not familiar with them, here's their 'about me' page:

The part I loved was this:
Almost everything is done right in that building, minus a couple small heat shield fabrication pieces (and they are working on moving that in house, too, I think).

I arrived at their facility this morning before anyone showed up (traffic was light on the 57N), and snapped a few external shots:

Anyone who has been there knows that the area is covered with feral cats, most of whom were absolutely fearless and adorable. Sorry, I love cats.:

My BRZ ready for testing!:

I passed 3000 miles on the way up there (don’t worry, my passenger took the shot):

While I was waiting for my ride to pick me up, Adrian asked if I'd like a brief tour of their facility, and I was extremely impressed. 100% of R&D and production is handled right here in Pomona, and all the materials were sourced from the US, as well. These guys love the company and love what they do. Everyone was all smiles there, and a lot of the guys working on the metal came up to shake my hand and welcome me. Seriously impressed.

First, the tubing is delivered and stacked outside their workshop. They go through their stock extremely fast, as orders are constantly pouring in:

After the metal is mandrel bent (their machines handle up to 3.5”), they cut it all to specification here:

Then it goes off to these guys. These gentlemen do all the welding. Pretty much all their welds are actually double-sided, which increases the strength of the weld.

Here they are polishing some of the first welds. Each piece goes through numerous polishing processes (sometimes up to 4 or 5 different stages per piece):

All the MAF sensor mounting blocks are cut outside and prepped right on site:

Their turnaround time is awesome. They can have an intake or exhaust made from scratch in under an hour, depending.

Once the pieces are completed, they either go to Shipping and Receiving to go out to distributors, or go into their ‘light stock’ area. I think the black (rather than polished) are more popular, so I think they try to keep more of those on hand:

Here is one of the rough prototype intakes, ready for further testing! I smudged out the numbering in the pic because, honestly, I was concerned about posting too much proprietary info. The guys at Injen were all incredibly nice, as well as genuinely cool people, and I don’t want to do anything that may cause them any grief:

This is their exhaust dyno location. They are currently building a new work area for all of their intakes, with a separate dyno, but this is where the magic happens, now:

Some beautiful metal work outsourced to Injen from an (unnamed) vendor:

I really hope to have more pictures of the installed exhaust, as well as videos and dyno results this week. I can't promise anything because, frankly, these guys are insanely busy and I'm not going to wander around under foot. I wish I could spend more time there, but I'm just the guy who's letting them use his car, and becoming a huge fan-boi in the meantime. :clap:

Could you ask if the intake will be tested by CARB? I know that they used to send their intakes for testing but I'm not 100% on it anymore.

WOULD IT KILL YOU TO RESIZE PICS?? THANKSSSSSSSSSSSS

Not his fault.

The forum software should re-size automatically, better yet there should be a plugin that should be added. :iono:

Looks good! You're at 3k miles already!

The intake will be CARB legal, yes.

I actually did resize the pics, sorry... They were originally 5 times larger. I dropped them to 1280x960, which should fit any modern widescreen monitor, including laptops.

Mobile phones and such may be out of luck, though. :P

Yeah, I've had the car since 5/26, and already put over 3000 miles of almost exclusively street driving miles on it. Mostly up and down PCH and around Santiago Canyon. :)

Injen is an incredible brand. I have had intakes for my old ford focus, mercury cougar, and now my eclipse. They make a 3" exhuast for the eclispe that I am planning on getting, and it is the highest rated exhaust on the market for it. glad to see they are working on this platform, as I love Injen and hope everyone goes with their products

You could use this, it would help all of us:

R&D at Injen is curious as to whether people would prefer a silver or black heat shield cover. The heat shield itself will be black, and the tubing will be available in either black or polished.

Added poll to thread to help track, but feel free to add comments or questions and I'll pass them along.

How come intake developers are placing the MAF sensor so close to the TB?

No clue, but I can ask.

Here is an example of what the silver would look like (on a different car). I should (hopefully) have pics of black tomorrow.

Here's the response I got:

Looks like more people are preferring black, at this point. Cleaner engine bay > more flash, maybe? :)
