Finally got my Aquamist system installed. Car is running good and will go to the dyno tommorow. Also will change the pulley tommorow to up the boost(3.25). Check out my homepage for some pics of the engine bay and the tank in the trunk. Let me know what you guys/gals think of my little project. Thanks

Looks nice Pablo can't wait to see your #'s you should definatly be over 300 to the wheels. Did you go with a steel or metal idler pulley?

 

Not yet on the pulley..Have those things been made yet???

 

Pardon my ignorance but I usually just drink alcohol... What is the alcohol/water mixture supposed to achieve? Do you spray it into the combustion chamber?

 

It is used to cool the charged air of the supercharger and also prevent detonation. This system has been used on many turbo and supercharged cars. The reason you use alcohol with the water is to not reduce the octane in the motor.

 

Which system did you get (don't say the Aquamist water injection), I am wondering which one from their website- http://www.aquamist.co.uk/cp/cp.html (System1s, System2s, System2C)

What is the price of the kit that you are using and is there any need for anything else (MF2 Injector driver)

I know that I want to get a water injection kit, but I don't know what kit it is that I should be getting, how much it costs, and if there is anything else that I will need to get this kit to work.

Can you give me some specific answers please?

 

The system that Im using is the 1S system. This system works off boost. I can actually get you the system since I have an account with them. If you want the 1S system your price will be $435 shipped to your home. By the way is your max supercharged??? If not maybe the 2S system could work for you since that one comes with a computer that you can have the mist kick in with RPM. Let me know if you need some help.

 

For metal idler and tensioner pulleys, contact DanNY. I'm his guinnea pig.

Congrats Pablo! Did you mix 80/20 (water/methanol)? Make sure you check the peak boost tomorrow... remember I lost 2 psi?

Good luck!

 

You got fire(nos) and water(aquamist) boost now huh Pablo?!? I guess were gonna hve to start calling you Captain Planet!!! Especally after you pot your Dyno numbers!! Congrats man...
I have an intercooler and I'm getting 9psi with the 3.25. Didnt we discuss already that the water injection might rust an intercooler? If not...hmmmmm

Deac

 

Actually Lance from TOYOMOTO told me to go 50/50 ..so if the car goes bOOM then he rebuilds it stronger!!!lol Ill let you know about the psi but I drove it pretty hard and didn't notice any loss in psi it hit 8.

 

Excuse my naivity, but from what I have read so far I do not understand one thing. If you do not have a supercharger, what good would either of these systems do. I must be missing something.

Hobert

 

Don't you inject right before the Throttle Body(after the intercooler), so how would it rust the intercooler?

 

Help me out with this-I'm still learning...

Would this cooler be of benefit to an N/A engine (w/ all the standard mods)?

And what about for Nitrous users (since I'm contemplating this upgrade)?

 

Yo Pablo man.... put the pictures of your chrome CAI SC pipes back on your website man!!! Thats my favorite part!!!
"N-Ter cooler" huh? Hmmmm :nughty: I'll check that out!!!

 

I do have a supercharger on my car right now. Does it matter how much boost you are running as to how much water you inject? How do you determine at what RPM to start injecting it at?

Thanks again for your help and for your offer. I will be in touch when I have the money ready to buy the kit.

 

Get my replay yet?

The 1s system is boost dependant. You don't want to inject too much water. 10% of the fuel is the recommended water/fuel ratio. Check out http://www.aquamist.co.uk for more info.

 

Kev,
I'm just going through all my email and I just got your reply. Seems like I am getting so many old replys since the .Org server went down (had to sift through a lot of old stuff).

From reading on their website, it seems like the 1S system is the way to go for a good starter kit and the 2S system just has more bells and whistles that may not be absolutely necessary. Correct?

I know that you control how much water that you want to injectby the adjustable pressure switch (between 3-30psi, factory set at 10psi) but do you have to (or would you suggest) doing any tinkering (raise or lower it from facotry 10psi)?

Would it be better to get a bigger jet size or is the supplied one sufficient?

Too many questions and I hope that I am not driving your crazy. Trying to get all of this stuff figured out.

 

Yeah, I got some weird emails (yesterday night) that dated back to Tuesday.

1s is the way to go if you're not concerned about the water/fuel mixture. I think it's fine for the average user until they go hardcore with tuning, then 2s would be better.

Nope, we control how much water is injected by using different jets. I suggest asking for .8mm, .9mm, and 1.0mm (I currently using 1mm) if you're using a smaller pulley, otherwise the default sizes should be fine. The jet flows when the switch is activated upon boost level. I have mine set to come on at 3 psi.

 

if you get pulled over with that in your car.. is that considered open container?

 

But it's not in the cabin.

 

Where should you buy the alcohol to put in the mixture?
How much does it cost?
What ratio should you use? 80% water/20% alcohol or 50/50?

Thanks again.

 

I use methanol. You can buy a gallon of Alcohol denatured with methanol for about $9 at Home Depot.

I use 80% water and 20% alcohol.
Water is a better cooling agent... but methanol will increase your octane rating.


Now why can't I postwhore with useful information all the time?

 

Think we should make a sticky about aquamist.

 

FAQ'ed... but not its own sticky. I'll gather the info when I get a chance.

 

How about some pics and install directions?

I know your busy, but damnnnnn!

 

Install will vary from person to person. I put the windshield washer reservoir under the CAI hole. Pablo had someone make a reservoir and he put that in his trunk.

You can't see my install except for the boost sensor switch and one nylon hose underneath the SC piping.

The stout of the reservoir is now a rubber radiator hose. I capped it off with a rubber stopper... it's located in front corner of the battery, behind the headlight.

Edit--- the hose is outside of the pic

 

Hey Kev have you tried to get some freezing water with ice and toss that in and do a run?? I know thats what they do with water/air coolers at the strip...I might just try this at the dyno and if it works then when i hit the track its ICE time

 

You might clog the pump... which will die if it's running dry for a long time.

Ice water (without the ice) would work.

 

Doesn't ice float?

If your drawing the methanol/water mix from the bottom of the resevior, you shouldn't "clog" the pick up unless you run low on mix.

 

Good point, Im gonna try getting ice cold water and doing a run.

 

Yes, ice floats but I don't know how hard the pump sucks the water from the reservoir. Since the car is moving, I'm sure small particles will be bouncing in the fluid. If it just so happens to get knocked to the outlet and he's boosting... uh oh......

I'm sure the it won't kill the pump, but I wanted to scare Pablo.

 

One other thing.

If the temp of the mixture makes a big difference then maybe you should make some sort of shield or better yet an ICE BATH that surrounds it. Or mount it in the trunk and submerge it in an Ice Chest for special occasions, like the TRACK!!!!

BTW, that is some nice header wrap on that intake tubing. Competition Engineering makes some type of thermal blanket stuff that cost a pretty penny, but it should work better against heat soak. Plus, it's got to look better than that!

 

My reservoir is outside the engine bay (sits where the CAI filter goes) so I know it's getting plenty of cold air. Track? What track? Hehehe

Yeah yeah yeah..... function first, looking good second. Competition Engineering, eh? I'll check them out, thanks.

 

Yeah, they seem to make good stuff for not too much money.

I know of some EXOTIC stuff, but man would it be expensive for as much as you would need to coat your intake tube.

Too bad I couldn't get this NASA fuel cell blanket we use at work in a 2-3" roll. Man that stuff is a couple hundred dollars a square inch , but a scrap 6" piece sure works well on our company Briggs go-kart for keeping the exhaust pipe from heating up the carb.
