Aquamist HFS-1 alky kit

**scheides** · 03-05-2008

This kit is going to take a few days to install, so I'll document it as I go along.

A few months back I decided to ditch my SMC alky kit and upgrade to an Aquamist. There were a number of different reasons behind this, but ultimately the Aquamist is the best kit/combo available right now. It all boils down to two things: instant on/off spraying, and actual support for a real life failsafe.

The Aquamist has a HUGE pump that is always on. The top 1/4 of it is a bolt-on manifold that they designed so it can supply a constant 125psi to the fluid line, no matter how much flow there is. Full flow or zero flow. This kit has a valve that is placed in the line just before the injection point that instantly supplies perfect flow or zero flow to the engine.

The other thing I plan to do with this new setup is pretty amazing, and really clutch for this whole project. ECU hacks are being developed for the evo 8 ecu that will allow different fuel/timing/boost maps based on a voltage input to a free ecu pin. I've worked with Aquamist UK to figure out a good way to use this Aquamist kit to do this. The DDS Flow monitoring gauge for this kit has an on/off switch, so I'll be able to switch between fully tuned straight pump gas map@24psi to a fully tuned alky map@28psi with literally the push of a button. Also if anything ever goes wrong with the alky kit, I will revert to my pump gas map so all will be safe.

There's lots more to go on and on about with this kit, but I'll just jump into it. This kit is really comprehensive. A picture is worth a thousand words (and parts!) For reference, the pump is about the size of one of those big 24oz silver bullet beer cans:

This kit is kinda DIY in that you have to assemble *everything* yourself, you have to source your own alky tank, and any installation accessories you have to get yourself. I got some nice techflex to wrap up the tubing and wiring as it runs here and there through the car.

Here's the mount I made out of 1.5" x .125" aluminum from Menards. This holds the tank and pump:

Mounted up in the trunk, wiring semi-run:

Ran the fuel line/wiring loom behind the seat supports, so they wouldn't get smashed by people bouncing on the rear seats:

Trunk lining/carpet back in place. Glad I went with the 4 quart tank, it fits perfect!

DDS gauge temporarily mounted on my steering clumn:

That's all for day two, I probably have about 4 hours into this kit install as of now. Lots of time sitting and fiddling with all of the little pieces

Also, just wanna thank Modern Automotive Performance, I'm psyched a local shop can hook us up with the best alky kit on the market!

uh oh, scheides is gonna be a little quicker than i thought.
I can say that if E85 ever disappeared then i would do this.

**scheides** · 03-06-2008

E85 is not easily available for me, so this is the route I'm taking

Anyone w/o access to reliably high-octane, quality gasoline should consider a setup like this!

looks really nice I will be getting the same kit for the evo as soon as I get the twin plate in it

**Halon** · 03-06-2008

lookin good!

Nice. I plan on getting one of these rather than going E-85. At least with this route, you can save a little fuel mileage.

Well it was *really* nice out today and after a few days out of town I was excited to get some time in on this project. First thing I did was yank the tank and flip the float sensor over into the correct orientation, I felt like a dumbass about that one but it was nice that everything came apart so nicely

I then ran power and my small hose to the engine bay, and mounted the flow sensor and valve to the right of the glovebox (thanks for the tip KevinD!). I am focusing on keeping the wiring as clean as possible so I did not finish tonight.

Extra hose wrapped up in case I want to extend this bit further into the engine bay:

Mounted valve and flow sensor (tucked to the right):

All is well when everything is where it should be and you end up with this. Wiring leads for all of the sensors. Thank you aquamist for keeping everything semi color coded!

Nice and tidy:

There's a nice spot just above the glove box that this will be secured to. For now its just in the glove box while I test everything out and get the DDS dialed in. The wires to teh top right will be tie wrapped a bit more so they're all out of the way:

TkrPerformance · 03-12-2008

looks good and that is still alot of wires

**Kracka** · 03-12-2008

Looks good so far!

**scheides** · 03-12-2008

woot! major milestone tonight, wired in the kit to the factory ecu harness, not sure how ya can get much cleaner than this:

And voila, the DDS is alive!

Still gotta wire up the dimmer, main power, and fill the tank....its so close I can taste the alcohol!

**Kracka** · 03-13-2008

Looks good!

So, uh, how much power does it make?

craig · 03-13-2008

that looks really nice

I dunno, how much does your car make?

We'll find out here shortly...

DSM_421 · 03-13-2008

Wow, really impressive sheides, I can't imagine all that wiring was easy to keep track of.

Looks factory like, atleast who may ever buy your car in the future will be getting a car that was well done.

Kevin 1G Drummer · 03-13-2008

Sweet! Looks very nice

Defiant · 03-14-2008

The OP is rich...So the more money he has the more stuff he can buy and surpass us all. I wish I was a site owner...lol

A//// Guy · 03-14-2008

Looks nice! Why not get gauge pods on the pillar or does anyone make a bezel to put to the sides and under the dash, like they do for 2gs?

DSM_421 · 03-14-2008

Peter, he said the gauges up on his dash are temporary.
