What can WATER INJECTION kit do for my setup?

[PARAZZI]

Hey guys,

I am thinking to get my a water injection kit for my d15b7 setup. If you need to know my setup: a td05-15g greddy kit boosted on 8 psi, running on 450 cc injectors, HKS BOV, DCP (custom) intercooler and 2.5 inch stainless steel pipings. What can the water injection kit do for my setup? Will it help or benefit my setup at all? Thanks in advance.

i'd invest in a d16a6 or z6 block before the water injection, but im not really familiar with the water injection i know a couple ppl on here are running alchy injection tho

The sole function of water injection is avoiding detonation. It is not a power adder.

So with it you can run higher boost and higher compression. I think the reason it's not real popular is because you need to tune for it which throws another variable into the mix. Mistakes, like running out of water in boost, can be fatal.

If you're serious look into a Hondata S300 which has built in controls for water/alky injection that will look at all the factors of your engine and decide when to inject. Then get a quality injection kit with a spray nozzle / pump thats gauranteed not to fail.

water injection is meant for high boost on pump gas.

it acts as another aircooler (intercooler).

yeah as of i heard water injection is like another intercooler, but with it while tuning i know u can advance the timing and also i am planning to boost from 8-10 psi. so you think this will help my setup? or at least be ideal for it? thanks.

[SOHC_STUDENT]

I would think it too risky on a daily driver.

If you need the water to run 10lbs boost what happens when your water pump goes out, you run out of water, your sprayer nozzle clogs up while in boost? Too many points of failure for a reliable car.

Now for a track car or occational use, ie in car boost controler w/ alky controls... then yeah it'd be tits!

water/methanol injection can do wonders for making more power. it allows you to be more aggressive with timing without having to upgrade to a higher octane fuel.

evosol made 324hp on his Vitara setup with the stuff :TU:

Well my personal opinion in regards to H20/alky injection and D series is based on the cumalative research i did before i purchased my kit.

Well there where 3 main reasons that led me to try alky injection.
1. being that D series have small bores and are kind of limited to knock when trying to tune for the most power, unless you run race gas.
2. I'm using Vitara pistons so anything to help supplement the fuel system by way of keeping things cool is good in my book.
3. I wanted to be able to run high boost on demand if needed on pump gas.

What are some of my initial impressions?
You ever notice that your car runs quieter during the morning when the exhuast system is cool? I did. Well its kind of weird but after a good run @20psi and some alky through the engine my exhaust is very quiet, i can actually hear my turbo spool up really clearly, which i couldn't before using alky. I don't have any scientific proof but this leads me to believe that the water/alky does something as far as keeping the EGTs down.

I ran my car during the "High school drags" last friday during 95+ degrees of heat with a fair amount of boost and timing on 92pump+ h20/alky and zero signs of detonation on the plugs. I was only able to muster up a 12.95 @ 111 2.0 60ft in the sweltering heat (I definately need some more seat time too).
I'm currently running a 5gph nozzle (315cc) and after racing all day/night at high school drags and "friday night street racing" i only consumed 2 quarts from my 4qrt container of 50/50 mix.

I think its great for daily drivers since realisticly you might only be boosting a fraction of your total driving time, waisting away expensive race fuel. Where as on alky/water injection you have it there when you need it.

i hope this helps for those of you who are looking into alky/H2o injection.

For those who are wondering, i'm running the Devil's Own alky kit, which i might be bias b/c i own one, but in my opinion has the best progressive controler on the market. Its small, easy to set up and control, and fully digital and fast acting.

[evosol]

Oh... and i wanted to add that as far as tuning for the alky/H2o, i have a dual stage manual boost controler so i just tune the low boost conservatively since my progressive controler is only set to kick on in the upper "high Boost" maps.

I don't race around town so i just leave my daily driving at low boost, plus 18-20psi on street tires is retarded.

[kyle h.]

if you posted pics, I'd say sticky!

[turboedpickup]

but you have a b7... that's good that you would reduce the chances of detonation (bye bye rods) but you still have b7 rods that may snap just from too much pressure... would it not? - but come an a6 or a z6...another story persay.

[evosol]

For the original poster's power goals i think the d15 rods should be fine. And as far as alky/H2o for your set up goes, it all depends on how you want to incorporate it into your set up. I think it would work great in supplementing your fuel system just to hold back detonation for daily driving, but you could also get away with out alky/H20 injection just fine too, depending on how far you want to take it.

After reading this post there is really nothing to add.
You all have given good advice.
I would really be worried about those pencil rods on that D15
Though.

thanks a lot for all your info, after all the different opinions and comments i have heard from different people. i am gonna bite the bullet and invest on a water injection kit. maybe as off right now i am gonna sit on 8 psi and probabaly after invest in a boost controller later in the future and increase my boost, with the H20 injection it will help me later on and also advancing my timing when i tune my setup gain. thanks guys.

Javieroh snap! the infamous Javier from JGE!! :shocked:

Heres some pics i posted awhile back, if you do get a Devil's Own kit talk to Chance and tell him how you heard about it, on D-series.org from the guy in Washington. :) I'm sure he'll hook you up, he sent me the kit with extra hose and nozzle for free. Very nice guy and excellent customer service.

Mine is mounted in the trunk b/c i can't stand any more engine bay clutter + i like the idea of a larger capacity jug.

Heres a shot of the controler. It reads off of the map signal, and adjust duty cycle per pound of boost. The knob on the left hand side controls when the initial alky kicks in and the right hand knob controls the point of full duty. So with both knobs you can control the ramp rate of the spray.

The nozzle mounted.

sticky it if you'd like... We should have a "official H20/alky injection thread" to discuss this stuff.

thanks for all the info, i will keep Devil's injection kit in mind man, and I will keep u guys updated. thanks a lot.

also refer to the write up in the new honda tuning. i just read it and i think it's a pretty good article.
