Thank you. Currently the tune and boost settings are the same. I am swapping in a ported engine within a few weeks. From there, it will be tuned for 20-25 psi on 50/50. Should see 500whp, but we shall see.

Thanks! The pump sits right there to the left.. It has the word "Garrett" printed on it.

This WI system is a boost driven system. The turbo boost pressurizes the tank and feeds the air to the atomizer. If you look closely, you can see the fittings coming from the turbo elbow to the tank, as well as down to the air side of the atomizer. Water is fed from the bottom of the tank to the liquid side of the atomizer. Water engagement is controlled my a simple solenoid.

Have you read the first 18 pages of this thread???

lol nice explanation.

The setup looks really good man. It's nice seeing these things come together and I'm glad I could help out where I could. I'm certain with your careful planning and attention to detail this thing will put down some big numbers. I hope you have a good clutch for the car.

As to the question asked earlier regarding a post turbo nozzle, that's impossible with a turbo driven setup. The Pressure after the turbo and the pressure at the nozzle would equalize and there would be zero flow. You might get a little dribble but that's about it. It's the same reason why our fuel systems use a rising rate regulator, for every 1 psi of added boost our regulator adds an extra 1 psi of fuel pressure. As far as the injector is concerned its the same amount of pressure, the rail might have 60 psi at this point but it has to overcome the 20 psi in the intake tract, thus the effective pressure and flow is still based on the 40psi we set it to.

Mechanically boost driven = Preturbo ONLY

It's the RE Single Turbo Track kit. I almost bought the Monster, but I am glad I didn't.
The track kit is pretty large as it sits. Ben actually featured my car on his site a few years ago when I did the single swap. I'm number 10 in the gallery I think.

Thanks Brent! I have a new ACT 6 puck & HD plate going in with the engine.

I'm totally stoked to get this thing tuned! Just a few weeks. Lots of work ahead though.

Are you running all -3an fittings for the setup?

Say if you had longer than 3m of inter cooler pipes would pre turbo water injection still be effective?, like would the water reach the engine in time?

I'm sure it would. the water should reach the engine at the same time the air does since the air is what carries it.

Looking at the pics, I saw you are not running the nozzle with the **** to regulatr water flow. So how much water are you running?

The natural progressive nature of the system increases flow with boost. Brent's nozzle flows around 550cc at 20psi. The flow formula he posted earlier in the thread should allow you to zero in the flow at a particular boost.

I considered installing the metering valve, but chose not to. The flow seems to be about right for most applications. It all depends on the ignition. A little extra water won't hurt as long as the ignition can fire it. I will be running 50/50 as well, so that should make things a little easier.

Tune session on the 10th of Aug.... ready to see what she'll do

I just gave my WI some love this week. Here is a custom sized air filter with Brent's system mounted to it.

for the guys who have been running this kit for some time, can you please let us know how the turbo is taking the water injection? Any blade damage?

I know Rdahm posted a youtube vid regarding some wear on his gt35r. Any updates on the cause?

I've been running mine since the start of this thread. Haven't had any erosion on the blades. Rdahm runs the same nozzle as me which is a modified nozzle from spray systems. The nozzles I use now and the others in this thread are a custom nozzle by spray systems that uses a larger atomizing port. The flow is pretty much identical and I can't say that I notice a difference in atomization but theoretically the new nozzle should have better atomization. That doesn't explain why he has some erosion and I don't. I know he was also not running a blow off valve which maybe contributed? It's hard to say with so many variables and differences in mounting locations. I'm curious to know if the erosion Rob has effected the power or spool at all? obviously the 26 psi he runs now is going to make so much more power.

Been running the system for a few months at 23psi. No issues at all.

Made 454whp & 390ftlbs at 23psi with 90deg ambient temps that day. Brent's kits are very effective.

i bet that gt35r is a fun turbo with that much power and nearly instant spool

Yes Sir! Lights my 285's up in 3rd at WOT. It's a blast. Yes, the spool is killer. I had been considering going with a bigger turbo but I'll likely stay here. Traction has become an issue. In this nice 60 deg weather, likely closer to 480whp. Intake temps are ice cold and the thing is an animal.

Thanks for all your support and help.

No problem, I like to see all the good results people have when running my kit and kits like mine. Glad I could contribute

I didn't see the question lol. I noticed my air filter was rusting in spots where the nozzle was pointing. Definitely important to mount it properly. My first setup was off center and collected water on the inside of the filter before going into the turbo.

Since I posted the picture of my new air filter, ive had no erosion.

I will add some recent things to this thread as well.

Since using the system, I have noticed a small amount of compressor erosion. I feel this is attributed to the shortness of my filter. My atomizer shoots dead center in the compressor. However, it's only about 6" from the blade. As I have posted, my space is limited due to my Vmount. I feel there isn't enough room to allow complete atomization of the mixture in such a short distance. Brent had no issues with wear, as others haven't either.

I am currently revamping my bay and will be upgrading to Rotary Extreme's final design of their Vmount. With this, the intercooler angle will change a bit allowing me to run an intake pipe and a larger filter. I feel this will remedy the problem.

Additionally, I am changing the way I mount the nozzle to my filter. Before, I used the fluid cap tightened with a large brass washer on the inside, and a rubber O-Ring on the outside of the filter to tighten down the nozzle. I will be changing this design to what Brent did. I will be welding two small studs on the nozzle body, then drill 2 side holes into the filter. I feel this is a better design as I am not using the fluid cap with a simple grooved ring to hold the nozzle on.

Thanks for the updates XLR8 and Rdahm. Definitely if we can track down precisely why some have shown erosion and others haven't that would be good for future people going mechanical preturbo injection. I'm curious if the erosion had any noticeable effect on power or spool characteristics? Rdahm I'm glad since you mounted the filter differently the erosion stopped. And hopefully XLR8 will come back with good news too when he relocated the nozzle.

rx72c sent me a PM today saying he just tuned one of my systems to 600 RWHP on an RX3 13B pump fuel. I remember when I first joined the club almost 10 years ago now, the practical safe limit was around 400 RWHP on pump fuel, that was pretty much the norm until a few years ago. Now we see 500, 600 700+ RWHP on a fairly regular basis. Pretty amazing what a little water can do.

@dudemaaanownsanrx7. Ive been shopping around for a water/meth injection kit and can across this thread. Will this kit handle a water/methanol mix? Im also running a BW S372 turbo. Ive been running it at 13lbs and now its time to turn it up, I just want to make sure that this kit can flow enough for bigger turbos. Thank you for your time.
