Can I run H2O inj without a tune for 2 months keeping boost at 22 psi?

C6C6CH3vo · Jan 9, 2006, 06:32 AM

I won't be able to tune my car right after installing an alcohol inj system. My ultimate plan is to run straight methyl and get tuned for it .

Would it be safe to go ahead and install and activate the kit and run straight H2O in the meantime until I do get tuned. Boost will remain at it's existing 22psi.

I would think it would'nt effect anything that much - the only change would be the tempertures and pressures - because H2O will not behave like a fuel. So if I keep all parameters the same, i.e., boost, timing, afr, then would'nt it be OK temporary for say, 3 months

Thanks

In my experience plain water injection works the best if you are running lean A/F ratios. I have found that just injecting a very small amount of water was enough to keep my timing from being pulled back on my previous set up. In other words unless you are experiencing some form of detonation or are having timing issues, you will not be able to take advantage of the water injection. Slowcar has had the best experience with running pure water so far that I know of.

Oh and if you do run water make sure it is distilled. The plain tap water can clog your nozzle with deposits.

i think he means is it safe to just install the kit with it operational using water until he has a chance to get it tuned for meth. i dont think he is planning on tuning it for water and just wants to know if he have water injected without any tuning and site effects till then. anyone?

I would need to know if he is experiencing any detonation or is his timing being pulled back because of his present tune. Otherwise if he isn't experiencing any of these issues I wouldn't run anything at all until he is ready to be tuned on alcohol. I've found out that you will actually lose power if you inject water when it is not needed.

It's not knocking

I want to instal a kit early so I wont rush into it if an opportunity for a tune arises.

I'm not quite sure if an installed kit that isn't operating (off) is safe, like in boost and also want to do a few operational checks afterwards.

You could install your kit and use water to make sure everything is working like it should. You can then deactivate it and make it functional again when you are ready to be tuned with the alcohol. Just keep your boost down to a reasonable level in the meantime. I had my Aquamist water injection system deactivated until I was ready to start using it. I hope that this answers your questions.

Yep, you answered my question>

I do however fear I might get anxious and turn the boost up a little and test it then too.

C6C6 What is up? Did u install the 10.5 hotside? I was wondering if I could take a look at your alky kit. What kind did u buy? I would like to find someone in Charleston, SC to pay and install my kit if I can't figureout.

I don't have a WI/MeOH inj setup installed or even a brand decided on, but I do have a plan in works and I am gathering all the facts here so when everything is ready, I won't hook it up backwards or grenade my the engine through the hood.

I do know I will take my time and make sure it's functional early before the tuning even if it meant driving around for months as is, and is why I'm asking questions now. The car takes my kids to school and me to work

Look at you two ploting with out me........

Slow up, I'll be home in under a week..................LMAO

You could run water only, no prob. The water will cool the intake charge, make the air more dense and stuff more in the cylinder. Max power will take backing fuel and raising timing a bit, however it will work on just water for the time being. Jet size and kit is unknown however.

C6C6CH3vo · Jan 10, 2006, 12:28 PM

Thanks TTP, thats what I thought, that running DI H2O untuned at normal boost will not hurt anything and will infact provide a more solid boost - colder more dense air

C6C6CH3vo · May 18, 2006, 09:51 PM

Thought I should provide my results of untuned alcohol since I spent the past time planning and installing the alchol kit since I posted this thread.

Anyhow, instead of using water at 22 psi I'm using the following:

80% methyl - 10% isopropyl - 10% H2O mix
24 psi boost
Snow 2D Kit with flow monitoring WG sol failsafe
375ml/min (@100psi) nozzle under 150 psi pump

Allthough untuned, I do have to say that by the butt, the car has gained more than what I got from cams, hotside, and whatnot all together. I expected less than half this from just cooler intake charge

. Cant wait to get tuned to tap the other half of fun it holds.

i totally agree with u on this......when i had alky with no tune....it feels amazing fast,,,it was giving me the most power than anything like cams etc,,,,, i boost it up like 26psi with alky no tune........of course later i got tune...but didnt notice a much in power difference between before and after the tune.....\

like al said, tunning only helps .....because with alky kit u wanna run rich condition , and alky likes to run rich without hurting the power performance...maybe loss of a few hp.but .better be safe than sorry just incase when it fails
