Custom Water/Methanol Injection Setup
 

I started doing some research on adding a water/methanol injection system to my supercharged 572.

I will give you a brief overview.

After looking at all the systems that were available on the market, I narrowed it down to AEM and Snow Performance. After numerous emails back and forth with their tech support/sales people, I felt that the Snow Performance system had more to offer and I felt a little more comfortable with what I was buying from Snow. I will say that initially AEM was quick to respond to my email and answered all of my questions and I had to send a few email to Snow to get them to respond. I almost gave up when I finally got an email back. After receiving that first email, they were responsive to all of my questions.

I did not want to use a stock ugly plastic bottle for my methanol tank. While AEM seemed sort of clueless when talking to me about using a different bottle/tank, Snow walked me through the issues I might see. Because methanol eventually turns aluminum chalky, I decided to use “Kreem” tank liner on the new aluminum tank I fabricated for this setup. Kreem tank liner is primarily made for lining motorcycle tanks, but will work on any tank that gas, diesel, alcohol or methanol is stored in. Since my tank is also at the same level as my intake manifold, I needed to use a solenoid so that water/methanol would not be sucked in to my intake, when vacuum is present. AEM did not offer a solenoid option.

My engine has a sheet metal intake. When I had it built, I had 4 - 1/8” NPT nipples added on the underside of the manifold for future use. I guess this new system counts as future use and decided to plumb a dual nozzle setup into the underside of my intake. I used 2 – 375ML Nozzles. Snow was very helpful in assisting me to determine the proper nozzle sizing.

The custom tank I made has a bracket for the pump and separate bracket for the solenoid and controller.

Before this water/methanol injection system, the car made 1015HP. I plan to get it back on the dyno for some additional tuning and will post the results I see from adding this kit within a week or so.

NICE! Have you had her on the dyno yet since adding the meth? Your IAT's are going to love it...:thumbsup:

I run water or water/alky injection on all my pump gas forced induction builds. Very good idea. You plan on running straight water or a water/alky mix?

I haven't had it back on the dyno yet since I just got it installed this past weekend. I am going to try and get it back on the dyno for some fine tuning sometime over the next 2 weeks. I will post results once this is done.

I run a 50/50 mix of water and methanol.

Looks great! When you post your results, let us know how your setup works with one/both nozzles and which percent they're driven.

Thats an awesome setup Ive been using water/meth for about 4 years now on turbo cars it works awsome. How are you controlling the spray boost, maf voltage, or IDC? They have a slew of new controllers out these days that can do all kinds of mapping. I always used Aquamist jets on my systems since they seem to have the best atomization.

Side note: Have you ever had issues with the hardline fuel lines mated directly to the motor? Ive always worried about the vibration causing stress in the fittings and leading to leaks.

I cannot choose one or two nozzles. It always uses both nozzles to spray.

The spray is controlled using the Snow Controller and is based on boost to control flow. The curve starts at 3 pounds of boost (about 10% flow) and increases until it hits 100% flow at 12 pounds.

I check the connectors every few months and tighten them if required. I have never had an issue with the lines.

Cool car.

What's the electric fan in the hood for?

To pull excess heat out from under the hood. I machined the stock hood louvers between the ribs to open them up. It drops under hood temps by as much as 30-40 degrees and engine temp by 5-10 degrees.

I'm taking note of this idea. :)

Do you have the fan sucking hot air out of the engine compartment or blowing cool air in? Can't tell if it's a puller or pusher fan in the pics.

Also, I'd like to see some pics of how you reworked the hood internal bracing around the other vents you added.

The fan sucks the hot air out through the stock hood ornaments that I machined. I will try and take some pics for you to see.

Just had the car on the Dyno. After making some A/F adjustments, the car picked up about 70HP, making 1085HP.

Thats some nice gains almost 10% what fuel is your base?
