Running 100% Water ? What to Tune for ?
Ok so Ive been searching but not with much luck besides the sticky up top about running 100% water.
I installed my kit but I cant turn it on yet because my wideband sh!t the bed and I cant tune my AFR. So Im wondering what I can do if I use 100% water ?
I know I cant lean out my AFR and advance timing but can I turn up the boost ? I know people say to run water if you run out of meth so Im wondering what the limitations are.
My car right not has a zero knock tune at 24 psi running a 12.0 on spool and 11.5 right to redline.
Anyone has had some experience with this give me some advice please. lol. Thanks.

Most dont do 100% water but if you insist on doing this I would get the smallest nozzle possible, keep the tune how it is and use the water injection just to keep temps down a little.
But I heard if you want to make more power you have to lean it out like crazy 12.5 or higher to see any gains, oh and boost to 30psi.

Yah see I was unsure on what the limitations and circumstances are. Ive read a lot of threads and just never came across the answer to my question.
Only reason why I was going to do water is because Im waiting on some funds for a new wideband so I cant tell what my AFR's are. I thought with water you only are able to turn up the boost and nothing else seeing your not raising the octane rating.
From what your saying though is that you can lean it while turning up the boost.
Either way I guess Im screwed because I only have a M7 jet and M10. Also have a dual nozzle upgrade just in case.
Looks like there is nothing I can do until I get a wideband huh ? That sucks seeing Im already anxious to get it working.

Thanks Ill take you up on that once I figure out why Im not getting power to the vcs-3g i believe it is.
I have the Labonte ISG-S3 and like I said above just taking my time with it and today go to finish it up which consisted of only hooking up the last red wire from the vcs-3g to a switched 12v source. I checked all my other wiring and everything that needs to be wired up is and done right.
Checked with a multimeter for power at my source and all is good so I am lost at the moment. I pm'd Dan a few minutes ago so well see what he says. Tomorrow Im going to jump a wire straight from the battery to the vcs-3g to be sure.
As for my mixtures. I think Im leaning towards a 50/50 mix. Ive been doing a lot of searching seeing waiting for answer's gets you know where. I have come to my own conclusion's based on other's and common sense and Ill be leaning towards 50/50 mix or 75%meth/25%water.
Only thing Im not sure on is what jet I should go with or just go with both nozzles and tune for it.
Long post I guess didnt mean it to be but one last thing with the Labonte nozzles. There is the filter and the what Im assuming is a jet inside of it with a slit in one end and a cross on the other. I wanted to find out which way it was supposed to go in. Anyone know what Im talking about ?

In terms of cooling properties I believe water has the advantage because it takes more heat energy to make it evporate. It will keep the temps in the combustion chamber cooler.
Meth has good cooling properties and is conbustable, this is why I believe people perfer meth to water.
In terms of limitations of water, I am not sure. Run somewhere between stock and what people are running their meth at. Maybe run 25-266lbs of boots and keeping your afr's near 11.5 at redline. Start around 24 lbs and tune for 0 knock increasing boost untill you are around 25-26lbs.
