Yes, I like to run a smaller jet and 100% water vs a larger jet with some percentage of alcohol. Some guys like to run huge jets and lots of alcohol. I use it more for a reliabilty tool than a power increasing tool.H20injection said:Very nice are you using 100% water?
Got any schematics? That sounds really cool! Are you tuning around water or just purely for reliabilty?coach said:I agree and have the same setup as mike going in. Smaller jets with pure water for the cooling and reliability effects. I make enough power without needing more from alchohol injection.
I do however have a dual nozzle system going in. I have 3 pots and a compator system to run a single smaller nozzle, single larger nozzle or both together. This is referenced off the MAF signal.
What size jet are you running? and where are you injectiong?choaderboy2 said:Yes, I like to run a smaller jet and 100% water vs a larger jet with some percentage of alcohol. Some guys like to run huge jets and lots of alcohol. I use it more for a reliabilty tool than a power increasing tool.
I run a .5mm when running C16 for power and high boost. I run a .7mm for running around at 14 psi on pump gas and a 1mm for road racing to stop overheating and to assure no BOOM.H20injection said:What size jet are you running? and where are you injectiong?
1mm is good for insuring relaiblity at high boost on a 2 liter motor. If no other tuning changes are made you will lose about 10-15 hp with this sort of water volume. If you have an inefficent intercooler/turbo, your power could actualy not be changed much.H20injection said:I am really trying to decide what jet is the right size for me. I have a 1.mm in right now and dont really know if its to much or what. How do you guys select jets?
I knwo that is the general guidline but have always fond that that is too much water for all but for keeping the car from overheating on the road course. That much water looses power and its hard to get it back through tuning. What have you experianced?coach said:Glad you made it over here man! Jets are rated at a specific CFM based on the PSI of pump you have. I have heard that the jet should be about 25% of the total CFM of your fuel injectors. I have
4x550cc=2200cfm so I need around 550cfm of water flow through the injectors. Find a nozzle that flows that amount at the psi your pump is working and you have your base. Now you can adjust up or down in size as needed for advanced timing, fueling or whatever you want to add in.
You want to talk to Richard Lamb, he was the older asian guy with the british accent, he owns the company and is the brains.NX$paniard said:dead-on Mike!! I spoke with Aquamist at SEMA this year.. their techs.. one was a hillbilly dumbass... they both stated that for a 2 liter turbo to begin with the.7mm jet and work your way up or down (usually-but not always, up) depending on how you are tuning.. as Mike stated either around the water system, reliability or looking for more power---again depending on the efficiency of the turbo setup(ic and snail).
Thats awesome taht you were able to draw that much power form the pump gas!!! definitely a good aspect for street/daily driven turbo cars..
Mine is set up to turn on right before the torque peak were cylinder pressure is the highest and detonation is most likely to occur. Then by the nature of engines, the excessive water on the top end takes care of itself.coach said:With my system and the dual nozzles I ordered a .4mm nozzle and a .6mm nozzle so i will have those sizez and a combined size of 1mm for adding water. The controller will be nice cause the water will be more linear to engine load and fuel. I don't like simple boost setups cause you have a ton of water right when you hit the set boost psi then at WOT your water is much less compared to air/fuel.
