Just want to fill everyone in (that are mildy interested) on an intake test I'll be doing this week if all goes well. The dragstrips are Atco Raceway in Atco New Jersey on Tuesday night and Cecil County Dragway in Maryland on Wednesday night. On both nights, I'll be testing out various intake setups. I have no expectations. It's just what I do as a hobby and having fun. Here are the setups I plan on doing (if I manage to get all the parts together).....

Car: 2015 LX CVT (Everything is currently stock)
Maf sensor: Maf sensor pipe piece was cut out of a stock 2015 maf air sensor housing. I ordered this previously to be cut up for testing.

1) Stock intake setup,


2) HPS Intake Cone filter (2")--> Maf Sensor --> Throttle Body (Aka Myxal Intake on a Stick)




3) 2.5" S&B Cone air filter --> 2.5" straight pipe --> 90 degree 2.5" - 2" Reducer, --> Maf Sensor --> Throttle Body (Myxal Short Ram)
This setup will be angled towards the firewall with filter close to the firewall/transmission area. It is only a test!




~~Bonus Intake **Work In Progress**
4) Stock cold air inlet--> 3" flexible ducting --> 3" inlet to PRM air filter --> 90 degree 3" piping --> 90 degree 3" - 2.5" coupler --> 2.5" straight pipe --> 90 degree 2.5"-2" 90 degree silicone reducer --> Maf sensor-->Throttle Body.
**Will update with pics once it is completed**
Pic below is the general setup. The only part not connected is the ducting I have that will connect to the cold air inlet on the top part of the bumper. I have the piece but I have to perfect the discharge side of the PRM intake as it goes to the 180 piping. Once I get that right, it will be done.





I have no expectations either way. I've never been one to guess although I have an idea on how this could turn out. The stock intake looks like a good setup but I somehow have always been able to extract a little extra horsepower out by changing it from stock. Either way, the timeslips won't lie.
Yes, I could dyno and I love to dyno but there is none near me anymore and this is a real world test. Feel free to stop by the tracks yourself if you'd like to test one of the setups on your 2015.

This is all for now. I'll update if/when I get those other two intakes put together. Worst case scenario, I'll only be testing #1 and #2 intakes. There are all kinds of variations that can be tested. Feel free to try this yourself. I'm familiar with hot engine bay air, intake diameters, lengths, etc. Just sharing!


Tested this 'track only' with a pantyhose intake to see what results I got. I call it the 'Myxal Vacuum Cleaner Intake'

16.01@88.96mph



Myxal LOL Intake (Laugh Out Loud)

This is basically the Myxal Intake on a Stick with a ridiculously huge air filter on it. I did it for shi*s and giggles. Restriction? Lol!


Here's the stock intake modified. Maf sensor bypassed. Gained .5 mph on topend at the drag strip. Air/fuel ratio's bumped up from 11.8:01 to 12.3-12.4:1.



PRM Intake!





Installed HKS Panel Filter for testing. The filter model is 70017-AK001. Test will take place on 9/26/14 at Cecil County Dragway. Will post results.



Completed PRM intake -->







Very First SRI-CAI ***Prototype***
Made this at the dragstrip by cutting up a cardboard box I had in the car. Haha!



New version! Official Myxal SRI-CAI


Yes, I'm dubbing this the Myxal Short Ram Intake, Cold Air Intake, Ram-air Intake. It has all the benefits of a short ram intake while sucking in cold-air through the J's Racing front grille. Woot Woot!

I can't finish it just yet since I have to run out and pick up the wifey and mother-in-law. I'll take a picture when I finish it when I get back. I'll add a top cover to it, and surround it with aluminum foil and duct tape here and there. :rotfl: I wanted to eliminate the accordion blue piece which makes the airflow a little turbulent. I also wanted to remove the 180 degree bend that is over the transmission and near the firewall. This can only pickup heat in this section. Intake air temps with the previous cold-air temperature always stays between 3-5 degress above ambient, with a best of 2 degrees warmer. This is awesome! Still, I want to strive for the air intake to be exactly the same as ambient. Can't hurt to try. This setup should be the ticket or pretty damn close.

And yes, it's lighter than the stock intake too. I mean, how much does cardboard weigh? I won't win any car shows but this will be interesting to test.




Edit --->
Cold Air Box in the making! Adding a 'lid' to the box to seal it off. Fun stuff! Laugh if you want! :rotfl:
Aluminum being added to help keep the cold air in and the warm air out. Hope it works!




Almost completed



Completed! Added the official name to it. Lol! This should be fun! :vtec:



Yeah, Yeah, I know the air pathway ain't the greatest since the air comes crashing against the maf sensor and all. Who cares! That's why we test things to find out what it'll do. This is only revision #1. Ideally, I'd like to move the battery to another location and utilize that area for a bigger cold air box and a bigger air filter (Lol Intake). This way, I'll have more flexibility on how the cold air enters in with less items in the way. To be continued!

Revision #3 -- Monster S&B Filter

Here's how it came together. Took me a little over an hour.

**Update 4/23/15**

The S&B air filter came in that I ordered. I wanted an air filter that was larger than the small HPS air filter (from the previous model Fits) but smaller than the HUGE S&B air filter I am currently using.

I had some concerns the about the HPS air filter being restrictive and wanted to rule that out. The huge S&B filter took up all the space in the box. Just seemed like the air getting into the box could only get into the maf sensor right at that location, while the rest of the filter was being smothered by the sides of the box. So...a filter that was sized right in between seemed like it would be perfect. I also wanted to have some extra filtering on top of the filter as well. Why waste that space.




I ordered a blue filter to match the silicone and other bluish stuff already in the engine bay stock. Why not!?!


Anyways...that's all for now. I'm happy! :thumbups:

Good work. Happy to see you actually test your mods on the dragstrip and not just butt dyno them.

Myxalplyx

Thanks for reminding me. I should've put up some more of the test info. Here you go….




It was 86-87F when I ran with the stock intake installed. I didn't know how to describe how much fuel I had left so I simply stated I had a range of 43 miles remaining. Nothing special about my launches. I simply mashed the pedal to the floor. My trap speed was lower than I expected. Was hoping for mid 80's. It is warm out though but no excuses.
17.261@82.34mph
17.133@82.66mph




Things started to get nasty with the long tubed hot air intake I made, utilizing the big 2" S&B air filter. Temps where 83F and the gas tank range in miles was 37. All that hot air being sucked up over the transmission seemed to have slowed the car down some. Take note of my 60ft time. It got slower. I expected a better low end torque with this setup. It did surprise me but this is why I test.
17.548@81.93mph
17.416@81.91mph




The Fit seemed to like the filter being installed on the maf sensor. I thought this was gonna be the worst of the bunch due to the hot air it is sucking in as well as being very short ram = Loss of low end. Didn't seem like it was the case here. The 60ft time was better than the stock and the long tubed short ram. Interesting! Trap speed picked up nicely with 1/10th or two drop in 1/4 mile time. The temperature was dropping, getting down to 75F on the last run. Also, gas was 28 mile range remaining. Even still, it was better than I expected.
17.033@83.46mph
16.854@85.67mph

forgot to add that the opening of that vent will cause NO HARM no matter what the "experts" on the freak site say LOL.

They weren't even born when 2 barrel drag racers used to put washers under the carb with NO gasket and jetted them real big causing the exact same effect you are getting.

It worked so well the practice was banned by the NHRA.

For their info the pipe that you are disconnecting is just a VENT and as long as you keep an eye on the A/F ratio so they aren't too lean you are getting more power leaning down the super rich stock settings.

Yes there is a minute possibility of introducing a microscopic amount of dust in there but it would be so small the amount ingested on a few runs will have NO detrimental effects on your engine.

ScarfaceSix

All good scoop to beef up the Fit. Thanks!

Myxalplyx

Claymore,

I never did respond to this but I'm in complete agreement with you. If I were to keep the stock intake installed, I would've left this just the way it is, removed the splash guard and kept the HKS air filter in place. That seemed like an ok setup with the stock intake.

I know if Oscar Jackson did the same thing or if HKS or Spoon put a logo on that tiny air filter I installed, it probably would've sold like hot cakes....with no questioning behind it. Haha!

So, is anyone else out there making intakes or for that matter anything else aftermarket for the 2015 fit. Also, I am not being critical or anything. Just seems like a lot of tubing for the intake.

Myxalplyx

Nope! There's nothing out there made. I have not read about anything in the works either. Only panel filters to replace your stock air filter (HKS, Spoon, Mugen). You are correct though, it is just a bunch of tubing. During my last tests with the stock intake and modified exhaust, the stock intake had a trap speed around 85mph (86mph with HKS air filter). The PRM intake was trapping between 87-88mph. You'll notice the intake/exhaust modifications ain't pretty. Functional...yes!

Stay critical! That's a good thing. I'm interested in seeing if manufacturers come up with something.

claymore

It's more fun and satisfying making your own parts.

s0x

did you get a 2015?

claymore

Nope still my old GD. That I also make parts for.

Good stuff buddy! (<-devmail)
