I am missing some thing some where, i know the Meth drops the Pre combustion temp much more than water But the Water Changes the Flame front on Combustion which dramatically effects the EGT's but not so much the Air temp, where as Meth Drops the air temp but doesn't do much for the EGT's.

Now are we talking Air temps because 50/50 is bound to work better? or are we talking EGT's because 100% water is Much better than 50/50? isn't it? This is why i am using 75% water to 25% Meth.


BTW you don't want neat Meth any where near you, it not only Burns with no Flame or Smoke but is absorbed through the skin and builds up in your system, If you Drink it or some one Drinks it by mistake it Causes Blindness, Brain damage and a host of other nasty stuff but you have to Drink allot for it to Kill you which is why i think its Evil stuff (leaves you a mess and doesn't have the good graces to finish you off) here in the UK most don't like Mailing/Couriering it but you can get severely done over by the law if you are caught with it in your car without the correct warning stickers (rightly so, i'd hate to be in a Crash and being burnt while every one is watching and thinking i'm going mad)

Good read up learning a lot
My car will be some where off 400hp and I will like to install the w.i only for safety our typical summer is 45-50c and 60c asfald temp plus 80% humidity in Cyprus
I do not have a thermostat, full fan settings , ic greddy and big koyo rad smaller water pulley for running the water pump faster , running water and motul antifreeze and I still have 78c the lowest I got on water and 45c on air the car has alsow custom air ducts and vented hood
So as u see I REALLY need it for cooling me down and not for extra power
1.can I install it after tune so I do not worry if it works or not
2.as we can not find ethanol or whatever u dude's use I will be running only water so will I be fine for safety and how mach water I will have to spray ?
3.for safety I will have to install in after the ic or before the ic or before the turbo or on the elbow?

THanxs for any info

so in conclusion the best locations to run the nozzles would be where exactly?

application: 400hp Single Turbo, Street Port, V-Mount.

thank you in advance

After the intercooler and as far away from the throttle body as you can get.

Water...or water/methanol? What's your goal...lower IAT or engine cooling? Will you tune with it? How sophisticated do you want to be with management? No pat answer IMO, too many variables. But a lot of info in the AI section stickys to help decide.

I would like the best of both so I would think 50/50 (water/Meth) would be the best option as to both lower engine temps and IAT right? or am I mistaken.

and yes I will be tuning with it after the engine break in period. the ecu will be Adaptronic; but I was wondering they offer a control management option for the Water/Meth

ive seen a lot of members input their Nozzle at the angle of the Elbow like the attached picture; would this be a optimal location? I will be using a Greddy elbow.

Yes that will be fine.

The elbow is not ideal, Narfle this contradicts what you posted earlier no?

IMO, ideally plumb your nozzle right post intercooler. I just moved mine from the Greddy elbow to the cold side IC pipe close the IC end tank. Allows more time for better atomization.

I've always been pretty happy with windshield wiper fluid--- primarily water, not much alcohol in there serving to raise your effective octane so if it fails not as big of a deal. In my experience you can run up to 22-23 psi safely with wwf and enough fluid. I've done it with Aquamist for many years in the past, and plan to with my current AEM setup. The OEM wwf tank works perfect and is large enough too

Yeah I feel like further away would be more ideal, but for the aims being discussed I don't think the location pictured is going to ruin everything.

^For water/methanol I agree, the farther upstream the more time for contact with the air and the better IATs. Not a big brain, but I don't see it doing much for atomization.

The most robust system is ensuring your car runs great without water/meth.

Get cold air into a low pressure drop intake filter. run an open exhaust, have a well ducted intercooler/radiator/oil coolers. run low 80C water temps, 0-10C over ambient air intake temps. good maintenance.

then throw on a water/meth kit to ensure the good times roll on. If you want 350WHP+ it might be good to use a kit. water, water/meth will vary. I think the blue crude from the windshield wiper fluid clogs stuff up so I make my own. I am tuning with a larger nozzle size soon. will let you know how that works out.

FWIW, the other injectors on our cars are much closer to the combustion chamber. So long as it atomizes well enough to not pool in one side of the throttle body, it's probably a wash in this application. Most of this armchair quarterbacking is better served in mega build threads. Midway on the stock elbow is probably very effective for a decent, smallish AI system.
