I've been running water/alky injection on my c5 for close to 1 year now. It works great on a boosted car, but takes some time to get it just right.

 

did you purchase a kit, or build it from components? it appears that the basic pieces are available but what did you do for water tank? do you have a high pressure pump on the system? where is the water injected? [ air bridge, throttle body, manifold..?] ;)

 

The two reasons that I like this forum so much better than the other forums that deal with the LS1/LS6 engines. 1st the members usually respond in a mature fashion. 2nd answers are usually backed up by real life experience. :thumbs:

 

:withstupid: Love to hear where you got your kit/components. :lurk:

 

vettemaster, would this benefit a heads & cam car? by how much?

 

MY EXPERIENCE WAS THAT THE WATER INJECTION ALLOWED WAY HIGH COMBUSTION PRESSURE WHILE MAINTAINING AGGRESSIVE SPARK CURVE. MY HIGH PRESSURES CAME FROM A TURBO, HOWEVER HIGH PRESSURE IS THE SAME BE IT MADE BY TURBO/ SUPERCHARGER OR HEADS ,CAMS, PISTONS... MY SYSTEM WAS AN INJECTRONIC THAT WAS VERY CONTROLLABLE AND EASY TO USE.. I AM MAKING INQUIRIES NOW TO SEE IF THAT SYSTEM WORKS ON OUR CARS.... EVEN IF JUST DOING BOLT ONS AND CHIP/ PROGRAMING.. I WOULD THINK THERE WOULD BE BENIFIT ... IF ONLY FROM PREVENTING DETONATION AND RETARDING OF SPARK... NOT TO MENTION THE CLEANING EFFECT...

 

On the turbo car I had the nozzle in the Air Bridge about I believe 4 inches in front of the throttle body and it was a pieced componets for a nozzle that had a lock nut to hold it in place with a very small hole, not even .15ths, and a small tube going to the windshield washer pump that held the acohol, I guy did use a water mixture of about 50% but I used straight out of the bottle and the washer pump kicked on at WOT only...I have run as much as 26lbs of boost but really would not recommend that much as it had a tendency to build a little to much power.......I put 60,000 miles on the car and never had any problems. I really see no reason why it will not work on any car....You definetly won't get a knock retard...A very cheap way to build power...If anyone beats me to this on the c5 I would like to know the results.

 

Got to tell you that the Snow Performance outfit is a lot prettier than the one I made and was surprized that it is a available componet all assembled.
I think I will even have to have on of those kits. Thanks for finding it Moundir and sharing it with us all...Also Shelby's kit....The Forum is a great site for all of us to share our exsperiences and problems. :hurray:

 

Sorry everyone...was just in a really bad mood when I posted that. I was not making fun of his idea, I was just venting. It was inappropriate and I am sorry. I do know about water injection from when they used it on WWII era fighter planes.

Again, sorry for causing a ruckus. :bb

Read two posts up. :seeya

 

sorry guy , I didnt see that, Its deleted,

 

Thanks for your reply. :thumbs:

I originally purchased a kit from http://www.smcenterprises.com (the kit is designed for turbo Buicks, but can be configured to fit any car). The guys name is Steve and he offers very good customer service and a quality product.

The SMC kit is very good, but I wanted to run Methanol and spray more volume than the SMC kit could support (the SCM kit was not methanol compatible at the time, but I think they may have better upgraded kits available now)

I now have a completely home built kit, but still use the SMC controller. The kit basically consist of the following:

-Shurflow diaphragm pump (capable of pushing over 300psi in my setup, these pumps are typically used as the water pressure system in boats and RVs and I was familiar with them from working on my boat)
-Small intermediate tank (this suppresses surging that is inherit in a diaphragm pump)
- Stock washer tank as reservoir
- 2 300psi stainless steel capable solenoids
- 2 m10 fine mist cone nozzles (these can be purchased at http://www.mcmaster.com)
- Stainless steel braided high pressure Teflon lines
- misc fittings, pressure switches, relays
- SMC controller box

The nozzles sit in my custom air bridge between my maf and the TB. The first nozzle is set to come on at 3psi and the 2nd comes on about 6psi (controls under my dash allow me to control turn on points and pump speed). I also have LEDs mounted in my pillar pod to show when the various nozzles are on and if the pressure is high enough. It also shows me when the tank is getting low. This is all custom, but it was very easy to setup (the SCM controller provides most of this).

Here are a few pictures to give you an idea of how it is setup. The pump assembly is mounted on the front driver side wheel well access panel.

This is not a great pic, but it shows the location of the two nozzles.

Anyway, I can't imagine this being much benefit on a non boosted car, but you never know until you try it. You can think of it as being very similar to running race gas. You won't see any benefit unless you are actively getting KR or you tune the car to run more aggressive timing or higher cylinder pressure.

I'm about to pull my heads for the first time this week, so it will be interesting to see how clean the pistons are.

THANKS FOR THE POST!!!!...THE SMC CONTROLLER LOOKS LIKE IT MAY BE WHAT I AM LOOKING FOR.... I HAVE EMAILED THEM TO FIND OUT WHAT I NEED TO KNOW....YOUR CAR MUST GET WITH IT... I LIKE YOUR SYSTEM..I HAD VERY SIMILAR SET UP YEARS AGO....PLEASE LET US KNOW WHAT MOTOR LOOKS LIKE UPON DISASSEMBLY...
