I am looking for basic Water Injection kit. I will be using it just for the purpose of safety to lower the chances of knock.
I have been looking at the AEM V2. Code number 30-3300
any input would be appreciate it.
what are your thoughts about that kit.?

Thanks..

 

I have the v1 for some time and it is excellent.
i believe v2 is exactly the same except better controller (has ***** instead of needing tiny screwdriver to adjust but otherwise the same)

 

Love your build and turbo choice.

If you turn on water/meth too early it is possible to hurt an engine. You'll feel it bog well before that point though, so continue moving it up until the transition is crisp/unnoticed.

The downside of using their controller vs. wiring it into a standalone ECU is you're unable to do it via RPM. I believe for the half a dozen cars I've tuned with similar setups, it pays off big to stage it later rather than sooner.

The AEM Nozzle you'd want to run is their Medium, 500cc, and ideally right after the intercooler so it has as much room to cool the intake air temperature as possible. Too much and it floods the intake. Use it more for temperature control, it works wonders.

Feel free to email me if you have any questions.

Thanks WANKfactor for you input and RGHTBrainDesign for your advise, very helpful. I looks like I will be getting this kit. It looks straight foward installation.

 

Very Interesting

 

I used the small nozzle on mine, I think 250 cc on the old kits. Its just for a bit of protection. I have enough power on pump gas. You can adjust starting boost and max flow boost. There is a test function so you can see what the flow looks like with the injector out of the car. I tell you its pretty nice, starts soft and then ramps up. Even with the small nozzle, myself and one whole end of the garage was completely wet with impossibly fine mist in a couple of seconds.
edit: boost not rpm, brain fart lol

 

I use one as my dyno WMI controller for development or when we don't know how its going to resolve itself in the chassis (engine dyno). They're simple and reliable. Honestly as long as you're using a real Shureflo pump (US made, I've seen some that were labeled as such but weren't made in the US) with the propler bypass almost every kit I've seen has been good enough for me to consider 'usable'.

 

Thanks everyone of you for your wise knowledge and input. I placed the order through rx7 store for the aem v2.
Mean while i will keep reading about it.

I have one more question. I have a fast reacting Air temp sensor, which its expouse filament. I have read mix opinion on this. Some said that there is not issues with it of getting blown away with water and other that don't recommend on using an expouse air temp sensor with wi.
thanks

 

I haven't had any issues in the past, though I stopped using standard thermistors and use thermocouples.

 

Cool.. thanks

 

Oh, you could have asked, I would have helped you out on the purchase!

 

OP, I haven’t read your build thread so not sure of power level, but there is a formula in the Stickys for nozzle sizing. An M5 nozzle would be for quite a lot of it.
Properly sized, it can come on early and stay on without issue or noticeable power loss. Too large of nozzle is probably more likely to do harm than coming on too early as he suggested..

I think nozzle placement should be AFTER the IAT sensor. Discussed in the next thread below this one. Reference post# 10.

Post IC, water will help only a little with IAT’s. Not nearly as much as alcohol. Water’s biggest effect is in the combustion chamber....cooling, knock and hopefully gradual carbon reduction.

 

Thanks Sgtblue,
I know that for wm 50/50 is recommended to use the 500cc nozzle, but what about just water? Should i use 250cc?
thanks again..

 

I used Howard Coleman's formula in the Nozzle sizing sticky at the top of this section. Basically nozzle size is determined by expected/estimated hp. This is cut and pasted from that sticky's first post....

On my particular car with my mods and estimated power level I ran an M3 (300 cc/min) nozzle, boost activated. Never had any issues. I don't even run ignition amplification.

 

Thanks for that formula, i thought i saw it somewhere. I will check it out.
