703rwhp on 34psi PUMP fuel Water Only injection

Yes they are rebadge. In aus NGK wont sell us the R7420 plugs. Have to get them from japan.
Yes we sell the spark plugs.
On my car that water is set to go flat out all the time so on and off system because my microtech is too **** to have a proper high speed valve to control it correctly.
My water comes on at 14psi. I cant bring it on earlier cause it floods the engine with water.
If i had a Haltech on my car and had a high speed valve, i would bring it on at 7psi and dial back some water in the lower boost areas and then dial in the water as the boost got higher, we have this setup on a customer car, gt35r runs 30psi. Works brilliant.

The dials easily come out of adjustment. That was enough for me to put me off the whole system.
8x8 fuel mapping tables isnt enough for 30psi worth of boost. Not in my opinion anyway.
I would prefer a on/off system over their variable purely for reliability and consistency sake.

A GT35R running at 30psi boost? I didnt know those turbos made power at that boost level.

Well unless you try it youll never find out.
Everyone seems to stop at 22-23psi and say that they have maxed it out.
It kept making more power and more power. I believe the water has alot to do with the turbo being more efficient at higher boost levels but its only a theory.

YES ! seems the Post turbo water systems are the way to go, i been playin with some Diesels and post turb. works great.
you know 1000hp truck is crazy, but its happenin. and fuel is only $2.30 US gal.

Congrats on the numbers, very impressive setup. Maybe one day i'll push my system that far. I completely agree on running conservative fuel/timing. Let the boost make the power. That's why the turbo is on there after all. I was thinking when you were running a bit lower boost that you had to lean out the mixture quite a bit to make power due to excessive water. I'm guessing the increased boost fixed this and allowed you to richen the mixture up? or is it still running a bit leaner?

Nice
Good r&d!!
Im a novice in mechanics so i had a question. I understand that preturbo= before turbo, I just don't see where do you tap on both your nozzels. If you have a picture it would be much appreciated.
Also, your water is set to come in at full blast at 15 Psi, if you don't reach 30PSI or even 25Psi what happens to your mixture of fuel/water? Isn't there too much water in your engine? or the fact that you are running 1700cc primary fuel injector saves you in the low boost area?Or dou you have your smaller injector of water come in at low boost (15PSI) and second bigger water injector at (30PSI)?
Off topic a bit but is your drive terrain ( transmission, drive shaft, axels, diff,etc) stock?
Thank you for your valuable information and time! I'm just trying to get as much info to run well with my set up. My interest of water injection is the additional reliability (engine temp, knock, EGT) and improvement. I belive you are on that path. My current set up: 20B mild street port, single GTK 850 turbonetics, microtech ltx12, primary 550cc, secondary 1000cc, 3 ngk coils and 3 bosh coils all ngk IR plugs. 470 whp 400 TQ at 10 PSI.

Afs are 10.8-11 on all boost ranges 20psi and up.
My car has 3 boost settings. 15psi, 25psi, 34psi. On 15psi it does run alot of water so my fuel mixtures their are 11.5-11.8:1 to compensate otherwise it breaks up alot. On the 25 and 34psi setting its perfect.
Egts do not get any higher then 950 degrees celcius unless im on the road and i load it up 2nd, 3rd, 4th , 5th it will go just over 1000 degrees celcius and im sure if i loaded it more it would get hotter.
My old engine use to see egts of over 1050-1100 degrees celcius and never minded it. So im not worried about the EGTs. Ive heard alot of people saying it musnt be over 900 and so on but my experience is showing me otherwise.
What i have found to be most most important is KNOCK, and this is where ive found water to be most effective. IT COMPLETELY eliminates any form of knock. Not just on pump fuel either.
we have tested a wi system on a car running e85 which was running in excess of 35psi of boost and we were picking up knock, setup a basic wi system with a 700cc jet and all traces of knock disappeared.
As for my jet placement.
Its in the front of the turbo. My inlet pipe has 2 jets right in the centre.Youll see the water line feeding it in the pic.
I have tried post turbo. Not as effective.
As for my drive train. I am running a FC gearbox and a ford 9 inch diff. Both have been holding up fine so far. Ive had alot of people say my fc gearbox will not shift at high rpm or it will break etc but it has been flawless. I will say my box was in very very good condition to start off with. Of course im using one of our In house twin plate clutches. Single plate clutches stopped working when we reached just under 400rwhp.

It's stuff like this that makes me entertain the idea of pre-turbo water stuff more seriously. I'm not sold on it for alcohol but for water, after seeing posts like this, I'm becoming a believer.

I couldnt really comment on alcohol as my experience is limited. But i will say as long as water is doing the job, i dont need to worry about alcohol or any of the headaches that come with it.
Tuning a water injected car is different to alcohol.
Your not replacing fuel with water. This is what people get wrong. You want lots of fuel, lots of water and a very very very strong ignition.
