is this Water injection any good??????

[stealthex]

sjoback, I'm a dumbshit. I went to the Honda dealership and saw the dx. You know the two vacuum hose on the right side of the manifold? There is a metal plate bolted on the manifold right under the hoses. That's where a new plate with a fitting for the nozzle goes. But I guess that means the spearco water injection won't work because you need that new plate with the fitting from JR. Unless JR will sells the plate seperately from the water injection kit. Anyone want to volunter to call JR for the plate?

[sjoback]

crap, that would be where my air temp sensor is.

aah I don't need that damn thing anyway

[stealthex]

How did you put an air temp sensor there?

basically it should work, but i'm going to call spearco tomorrow, and find out for sure, i will also find out of the pump and nozzles......

So does anyone know definitively whether or not the blower is sealed so that we can put this in before it? No rumors please, just actual knowledge from Eaton. I cant imagine the bearings not being sealed, but anything is possible.

As well, in that first link there is a 2nd kit for NA, I wonder if it has a stronger pump? If so why couldnt we run that pump with the first kit?? That might be worth looking in to.

Ok, here is my take on Water-injection:

After doing extensive research and bugging countless people, who actually use various water-inj systems, the best way to do it is after the blower. The proper pump is one that puts out at least 85psi with minimal drop-off in pressure. A high-pressure pump is required to atomize the H2O properly. The better the atomization, the more effective it will be in cooling down the charge before it enters the cylinder head. The poorer the atomization, the more space(water and fuel mix) is being used up by the H20. Therefore robbing performance. The idea is for the water to completely evaporate before it enters the combustion chambers. This is why the Aquamist system is so successful in Europe on Turbo and Supercharged cars.

Now the Spearco unit looks good, BUT it uses a much weaker pump that cannot keep a steady high pressure for optimum atomization. When I called Spearco, the told me "mounting the sprayer nozzle after the throttle body is definitely not recommended"

I would also like to mention here that a certain person known by myself, Bill at ZYDYNE and Larry at ENDYN, seriously F*CKED their motor by not evaluating the water-inj system they had and poorly positioned the nozzle.

On the other side, kameleon has had success but kam's nozzle is before the throttle-body and the charger is spinning 10psi creating plenty of heat to completely evaporate the H20 (so we hope).

So, beware and be careful with H20, we can drink it but our engines can't!

BTW, as I have mentioned in an earlier post, I have purchased the aquamist system (with the JR logo). I hope to button up my car soon and head down to RELIABLE and see if there are any gains. I will post my dyno runs for all of us to see.

I like your ideas, the best route looks to be to go through Aquamist or Spearco, but Whaich has an advantage and which is cheaper and most importantly, BETTER?

I want to use some H20 in my JR manifold 'cause I know it's gettin' hot in there and I plan on uping the boost to 11psi from my 8psi, so I'll certainly need an intercooling system.

Thanx and,

Yes make sure you inject the water after the blower. Injecting before the blower will lead to destroying the bearings inside the blower. I believe all of the newer units including the SOHC kits are tapped for H20 injection. Mine unfortunately is not.

EXSC,

The person who you are referring to suffered the damage after going on a high speed run 140+. He has since rebuilt the charger and he is hauling serious ass now. I saw him running at a recent track event(road course) and he was one of the fastest cars out there. Call Moss Motors and get specific directions on where to tap if you are unsure.

[EXSC]

Yup, that's him. I know exactly where to tap it is just a matter of time when I do :-)

[JRCivic]

Tap the hole very close to the center of the intake manifold... near the vaccuum draw for the master cylinder. If you have a newer manifold, there will be a shiny silver/chrome 6-point screw threaded into the hole to block it off. This is where the nozzle should go.

Atomization is the important thing here. The Aquamist/JR kit may be expensive, but it is the BEST product for what our needs require. Injecting before the blower is potentially damaging to the blower lobes and the coating on them... the water WILL make discolorations on the blower lobes and if you were to have a problem with your blower within its warranty period, the folks at Eaton/JR will reject a warranty claim due to the water consumption !!!
