So I am interested in learning more about water meth injection. I am looking more the cleaning ability of the intake system and the cooling of the charge air. I have read where this injected pre turbo will help clean the turbo, cac, and intake manifold on a Duramax with positive crankcase evacuation. So I am sucking oil into my cac and am sure it is saturated. Hoping to not have to reroute this to gain the performance of a clean cooler. Please let me know your thoughts.
Yes you can run small nozzles such as a do2 and smaller before the turbo to help keep it cool and clean it. you will still want to run 14-20gph of nozzle after the turbo so you can cool the intake air temps down and get the in cylinder cleaning you are lookign for.
Does this system use EGT's as a trigger point or Boost? My truck usually runs with less than 10-15 lbs of boost except when towing my 5ver so I would need a system which triggers on low boost or at a specific EGT say 900 degrees. Does your system offer this feature? Jabs

We offer both system. I do perferr the boost based setups and then you will set the start point to when you start getting having heat issues. 1/4 of your max boost or even lower.

That makes sense glad I asked as u are right when the EGT's are steadily high then the engine is already hot. If it begins the injection process before that then heat issues resolved..Thanks..Jabs
On the LB7 where do you put the nozzles? I found instructions for LMM and LBZ but instructions do not match LB7. I assume you remove the plastic cover over the turbo and drill them in the right hand intercooler intake (as you face the truck) The other intercooler intake has a MAP sensor and another gadget installed in addition to my Turbo Boost port. Please advise if someone has drilled out and installed the nozzles on their LB7..Jabs
Drilled and tapped them into the intake on the intercooler housing going into the intake side (left intercooler housing as you face the truck from the front). I put 1/8 NPT #27 plugs into the holes until I decide which system to purchase. Jabs

Thanks DevilsOwn. Was not sure at first but when I routed all the intercooler hoses and intakes I found the best spot. Not to bad of a job either. Thanks again for your reply..Jabs
I will try and do it today. What is the function of the black box I believe its called a resonator it connects to the air box but does not have any holes in it. It has the 6.6 Diesel logo on the top?
For my LB7 I drilled two holes starting with a small bit and then using the larger bit for the 1/8 NPT #27 Tap. I did the drilling and taping dry with no oil or lubricant. I then used a powerful vaccum to suck out whatever aluminum shavings may have falled into the intake. You will have to remove the resonator of black box above the Turbo to do this. I stuffed a rag into the airbox intake going into the Turbo as metal shavings would have gotten in there if you don't do this. Took all of 15 minutes from start to finish.
Devilsown;3917210]No problem, Post up a pic of where you thinking about putting if you get a chance.[/quote]
I have heard of ppl running windsheild washer fluid for the water meth is this ok to use if so what is the best to use and also if the nozzle was tapped into the drivers side intercooler pipe would this help cool it down more because it would be flowing through the intercooler or is it just best to put in the passengers side?
You want the nozzle on the pass side "outlet" of the intercooler you do not want the moister going threw the core. It will not pass threw properly. Yes you can run washer fluid the cheap stuff works best.
Since were asking Q's here has it ever been tested to see what kind of HP and torque can be made with just straight distilled water. Reason I ask is if your look at the atomic make up of the two periodic table elements of oxygen and hydrogen both can be used to create horse power via more air(oxygen) or hydrogen in the space shuttle. Also if you think about it the steam from the water now feels the voids in the volumetric eiffiency in the cylinder so you have more oxygen which is present in H2O.
Yes there is hp gains by just running water. How much of its is from the removal of the inlet air temps and how much of it from the steam in the combustion chamber. I honesty don't know.

We have done lots of dyno testing. from your previous qusetion it sounded like you wanted to know how much power is gained from cooler intake air and how much of the power gain is from in cylinder cooling. I dont' know anyway to break it down like that.
I know that usually most diesels that i have seen usually make between 20-50hp is the average.

Is that with the water/meth mixture or straight water. I know that bml2200 said he saw 10hp but there has to be more in straight water because of its atomic make-up you know.
Robby there will be no gains due to the exploitation of the atomic make-up of water in this case... since the water undergoes no chemical change. It's H2O in and H2O out, it just changes phase from liquid to gas.
But not due to the fact that hydrogen and oxygen are being used... that is just false. In order to make that chemical change you have to run electricity thru the water... as in those foolish HOH or brown's gas systems. When the phase change occurs you do get thermal expansion as the water vapor takes up more volume than the liquid... like heating up a pot of water with the top of the pot welded down... but again, you are not in any way, shape, or form "burning" the water or chemically changing it at all.
I can honestly say when i put my meth kit on no power gain was felt. Never dyno'd it so a little power could be present, but i can vouch for the increase in fuel economy. I run 50/50 mix, with a 550 and 315 nozzle setup.
Ok I got the boost activation switch hooked up and it is making my truck pop when the boost is staying steady around 10 lbs the switch came out set at 10 just haven't adjusted it yet what's the problem
Sounds like combustion quench to me and your trying to inject to much water/meth at to low a psi of boost. Try adj it a lil higher so your starting psi on the kit doesn't start til you have proper boost to use the W/M correctly JMO.
Yeah with the right system you'll see MPG improvement if thats what your after as well as benefit from cooler egt's and a lil more power. Check my sig out as I'm running it on a stock engine and playing with fire with my 06 LBZ! My kit is only used for sled pulling and I only use water to aid in a lot cooler EGT since it can get pretty hot while pulling.
Well you should see about a 200-250deg drop in EGT's and somewhere around 70-80hp increase with the kit I run if you use the 50/50 mix boost juice snow sells. I still have a couple gallons in storage as back up ammo for a smack talker If I need it but other than that I only use it sled pulling.
