-water Injection-
#61
and plan on running a similar system that all the Japan Forum guys run
and which one would that be?
These days I find the idea growing on me. Using it to make things better after the tuning is done. Not simply to be able to raise boost for more power, but for a reliability mod to a high tuned engine. No engine built for high performance purposes is "bulletproof". No matter how well built. Everything that can be done to reasonably lower the chances of a bad thing happening to a good engine is worth the effort for some people
I couldnt have put it better, great words.
I guess they are supposed to run around sucking in 80'c + intake air temp all day long 99% of the time till the water injection comes on at what ever boost you have it set for. WOW... that should make lots of HP and have a great power curve. NOT!
lol, I have though wi replaced the ic at first but after I gave it some though it really doesnt.
"I guess they are supposed to run around sucking in 80'c + intake air temp all day long 99% of the time till the water injection comes on "
thats exactly why I chose to have both, ic is not only a safety net, it really does make a difference, and to run wi all the time boost or not, well it would get really bothersome to keep refilling the water tank.

were all runing the aquamist S1 Race system, you don't really need the mapped system with a rotory because we're not usually boosting a lot so the basic system will cover it. If you were running some crazy boost then it would be nice to have the mapped system to add some more water as you went to the higher boost levels to keep things cool in the engine and prevent hot spots that will cause detonation.

City driving water injection armed:
On a day where the temp is 38C during my regular driving pattern in the city I will have 23-32 intake temps on average with extremes of 19C when im heavily accelerating to maybe 36C if I have not hit boost in a while (boost activates the water injection). On the highway I find it roughly the same, if Im cruising steady without hitting boost my intake temps will rise.
City driving without water injection on a 38C day my intake temps will rise to 60c. On the highway on a 38C day my intake temps will be 45-50.
This represents and extreme in temps, but shows the differences that water injection can provide.
I have a dual stage set up one nozzle in my IC end tank and one in my intake elbow near the manifold that is pointed toward the incoming air. comes in in full at 8 PSI

I've found with my intercooler, that at idle my intake temps are roughly around 50-60c in the hot Okinawan summer heat(95f+ with extreme humidity). As soon as I start moving(not boosting), they'll drop down to the low 40's. If I boost at all, my intake temps fall lower than 40c.
All these temps are taken during city driving...no highways in Okinawa(except for the e-way I guess)

In both your situations, one with water injection on, and the one with it off during normal daily driving around the city etc you should be having the same readings because it's still off until you hit 8psi of boost and I REALLLLLLY doubt your driving around in boost over 8psi 100% of the time in the city.
In your first statement alone it's obvious you’re full of it; let’s break it down for you. Real quick (I already hit part of it up above) you say
On a day where the temp is 38C during my regular driving pattern
Ok, it’s 100'F outside guys
to maybe 36C if I have not hit boost in a while (boost activates the water injection).
I haven't been in boost for a while, but because I have water injection installed even though it hasn't come on. I'm still running 2'c (4'f) lower than ambient air temps.
Also you still never said what you’re using to measure air temps?
Where are you measuring these my car is blessed by god air temps?
What size jet are you using that comes on at 8psi?
I personally think, well actually know you just pulled a bunch of numbers out of your *** or copied and pasted off some a rice boy site.

wouldnt be surprised. Then again what do I know...... it seems little fishy even to me though...

I've been reading up on WI for the past few months, and from the people that I have seen use it, they all say they use it to 1 raise boost, and 2 to be a safety measure. Out of all those people every last one of them had an intercooler, and said they would never just run WI. Just think about it if you are stuck in traffic at idle your temps are going to soar. And from everything I've heard, intercoolers really do not cause any significant amount of lag. All the pipes already have air in them it's not a vacuum so it doesn't take any time at all to pressurize them. All you have to do is shoot the air through them. As far as the methanol comment, I've talked to several other people who either run a mixture of methanol and water or full methanol. They all have great things to say about it. It further cools the intake charge, and it raises the octane. But again these people all have IC's wonder why?
