Not sure how much (if any) carbon had been removed after ~1.5L of meth mixture but warm weather is disappearing fast so back on the dyno it went.

That is a mighty fine torque curve. I am assuming that the small turbo is running out of steam in the top end?

Yummy. +20ft-lbs everywhere.

Now take it apart again, gotta see them valves!

Is Husky 94 not a good idea for an Aquamist kit?

Not sure how Husky 94 has anything to do with running methanol injection. I am just assuming that he wants to tune for Shell 91 rather than Husky 94.

So you didn't actually clean the valves just inspected? I guess it will be a good trial run to see if the methanol injection helps clean off the carbon. How long will you go before inspecting again? How often is the methanol injected?

I was thinking more along the lines of winter coming up, and perhaps Shell 91 being preferred in the colder weather. From a tuning perspective, I'm simply not sure how the type of fuel would react with the meth as well as other extraneous factors like the weather (since Sunny mentioned it).

The turbo can hold more boost.  I tapered it down since it is still pushing against the stock exhaust.

I just happen to be running 91 in the tank (switched before our road trip in October).  I mentioned the cold weather only because I wanted to keep the dyno sessions within reasonable temperature range.

To MY untrained eye, the right one seems to be a tad cleaner. That huge chunk seems to have disappeared.

I agree with this.

What conditions are you injecting meth based on? RPM? Boost?

I think we would all be very interested in any details you care to share on the system and your install.

What percentage of methanol are you using?

I did some research on aquamist they have multiple options for load based injection reference (map, maf, injector) which are you using?

Are you using the PWM valve the offer to meter injection?

Do you find that you are having to trim fuel to compensate for the fuel content of the water/methanol mixture?

It is set up to be proportional to fuel injector flow (based on pulsewidth and fuel pressure).  I have set it up to start spraying at ~4psi of boost.  This relatively low threshold is used to increase the amount and frequency of meth injection events to aid the cleaning process.  After the system was functioning I drove to Cochrane and went up/down the hill (~3km one way) 5 times, basically holding boost at 5-6psi for as much of the climb as possible, for sustained meth (50/50 mix) spray.


There is still a good amount of oil that comes from the PCV system so I may have to do something about that.

I'd recommend this setup from IAG.  It lets you run a PCV with the one below.

You guys only see a tad difference? You can see the metal now on the right one!  And look at the walls they are cleaner now as well.

A tad difference in visible deposit would be an accurate description.

A big difference between what is visible in the pics is also an accurate description.

Here is what I see. #1 -different lighting. (understandable due to the method of photography) This results in a visual of what may, or may not be less accumulation on the runner walls. #2 - Valves that have been moving around doing their jobs. Don't forget that when valves move they are also free to spin. The spin appears to explain the appearance of less deposit, I believe it's still there essentially unchanged we just have a different view. #3 - Valves again, they are clearly resting in a different position of the intake/exhaust cycle. The part that appears to be shiny and be clean when compared to the previous is in fact the runner on the other side of the valve that we could not see before because of the closed valve position.

These are my observations, right or wrong only time will tell if the meth injection is going to do what it's expected too in this application. There is no reason to doubt that it will.

I understand that the intent isn't to completely vaporize the 50/50 mix in the intake, just wondering what your thoughts are on the effect of manifold temperature and the pressure? Specifically, I'm wondering if you intend to disable the system under extremely cold conditions due to atomization concerns? I have zero experience with these systems ...

I was thinking about a small DIY windshield washer fluid system that would inject based on pressure and maybe temperature (two switches in series). The temperature and pressure would be set high enough that it would only inject when the turbo was pushing hardish. A basic surflo pump and nozzle that pulls directly from the washer fluid reservoir. I assumed injection would be downstream of the inter cooler to avoid droplet dropout.

There is still a good amount of oil that comes from the PCV system so I may have to do something about that.

I have been looking for a catch can that is a little more OEM looking. With zero mods on the car a big billet $400 AOS is going to be a little gaudy. Any thoughts on these two?

Purolator also manufactures a AOS AS-902 without the relief valves etc. (which I like) Supposedly $70ish although I haven't found one actually for sale yet. They are OE on Porsches so I'm sure they are available.

Love this mod for the 2015+ WRX and STI.

What did you end up doing with the factory turn signal bulb?

Put the OEM mufflers back on today.  Not sure if the mufflers from the Nameless axle-back got louder over time or just me.  Have to try other options next Spring I guess.

From what I've seen on other cars as well as from what Nameless has told me, their "muffling material" will degrade over time at a faster rate than OEM. That's why I opted for the deletes again.

With the Nameless axle-back, engine/exhaust noise comes from the back seat area and pervasive even at low throttle openings.  With the stock mufflers back in, engine/exhaust noise is muted such that the majority of it comes from the dash area (low throttle driving or cruising).

Hopped into my 06WRX wagon today to compare and the MadDad Whisper CBE+Full-Race manifold+downpipe turned out quieter/less intrusive at low throttle than the Nameless axle-back on the 2015 WRX.
