How much hp does the standard nozzle support that comes with the kit? I want to make sure I don't need a bigger nozzle. It seems that sometimes I can unplug the power to the injection and the logs don't look much different. Does that mean I'm not benefiting from it?

That depends on the water/alc ratio, water/alc to fuel ratio, and the air to fuel ratio.air fuel ratio. No, you can benifit from injection a lot without seeing a large change in a/f ratio because of it. This is cause you have to run a lot more alc then petrol to change the a/f ratio a given amount. It makes sense that if you're running a 50/50 mix(assuming you are), and you're not running an extreamly large % of injection, that the a/f ratio wouldn't change much. Course it couldn't hurt to make sure that your injection kit is kicking in when it should be, and that you're using the right size nozzle for you. If you have a stock turbo and stock injectors, I would think that the m6 nozzle(standard) would be more then big enough. If anything, I would think about using a smaller nozzle. Course I don't run as high of a percent of injection to petrol as many people.

It depends on when you bought it. As of about 2 weeks ago our controller kit ships with 2 nozzles. 1 is a 6 GPH and the other is a 16 GPH. We started to find that some STI/WRX needed the larger. The EVO's tend to need the larger nozzle as well. Prior to that, they shipped with the 6 GPH. By shipping with both now, things are covered regardless of power.

About 2 weeks ago we re-developed our 16 GPH nozzle. The new design has better atomization and spray pattern.

If you can turn the "TUNE" knob to 10 and dont get any "bogging" you may want to consider getting a larger nozzle.

I'll give it a try on 10. I've hit 7 with no bogging already. I know it's been about 2 months or more since i bought the kit. I only got one nozzle I do suspect that I'm going to need a bigger one though.

setting 10 can have as much as 30% more flow than setting 7.

What size injectors do you have? How much boost are you running? What a/f ratio are you running?

standard injector. Not sure on the size. I think David said 6gph. Boost is 22 peak 20 by redline. a/f is around 11.7

When the a/f ratio is richer, ya need to run more injection to get a given water/alc to fuel ratio and to split up the origional fuel and air particles a given amount. This means that if you run the same amount of injection with a leaner a/f ratio(to get the water to fuel ratio back to normal since it was probably low from running so rich), you might actually get a slower burn and more knock protection. Ie-Maybe running a leaner a/f ratio(like 12 or 12.5 to 1) could help you better utilize your injection?

Well I turned it up to 10 and floored it a few times in 4th gear. I couldn't feel a difference. It seems I need the bigger injector. What are the chances of me getting the bigger one?

I also noticed that if i set the start to 16 it doesn't come on until i see about 20 on the gauge. If i set it to 1psi, it immediately comes on. If i set it to about 5psi it comes on around 9-10psi on the gauge. Is this just normal because when the controller sees the boost it triggers the pump but takes a sec for flow? If it's normal I'll just turn the dial down. Just never really paid attention before I guess.

So as long as the delay is normal I'm fine. I guess I just need the bigger injector. Does it have the same threading and size so that it will fit in the existing hole?

You can order a new nozzle off the site if you want, just let me know and I'll point you out to our new one. The only reason we sent a "free" nozzle to that other guy is because he just ordered a nozzle 1 day before we released our new nozzle and I felt that wasn't right.

these are calibrated using a compressor and are very accurate. Its possible that the calibration is off, its possible that the gauge is wrong and its possible that nothing is wrong. Look at the knob and align the line exactly with 16 or 20 and. To know for sure what you are seeing you can hook up laptop to it and datalog, thats the best way to see how much boost it thinks its reading. I have yet to see any controller that was calibrated wrong as each one goes through quite alot of testing, but its possible.

If thats the case I'll be glad for you to send the unit to me and i will test it. If its calibrated wrong I'll send you out a new unit and I'll pay shipping to you (you pay it to me). If its calibrated right, you will need to pay shipping back to you.

yes its the same, 1/8th NPT.

How much is the nozzle? I'm glad it's the same size. My gauge is right because my logging software says the ecu sees the same thing. I checked and it's right on the line. My pump is all the way in the trunk. That's the only thing I can thing of is the time it takes to initialze the pump. Once my green hits like 10psi it just seems to jump to 20ish. I don't think it's calibration of the controller either. Cause if i set it for 1psi it will come on right at 1psi on the gauge. If I slowly ramp to the desired psi on the gauge it will match what the controller is set to. But if I just floor it there's a delay. That's why i was pointing to a delay of the pump?

I cant discuss price, they are the outside thread injector on our website. I want to replace your controller for you, its not defective, but its obviously calibrated wrong. If its reading the wrong boost its not going to flow correctly. Please send it UPS or fedex to:

Coolingmist, LLC
6010 buford highway SUITE B
Norcross, ga 30071

Do not send via US MAIL, it must be fedex or ups. Also request a signature. Make sure its insured.

As soon as I get it I will send you a new one.

Is the controller just quick disconnectable? I mean I don't want to have to cut any wires or anything. If so and you'll replace it sure I'll send it in.

yes, it has a white connector on it. Just press the tab and pull apart.

Check this out(posts 90 and 91). They're just my calculations and all, but maybe it would be good to do your own calculations before you get a nozzle which flows more then twice as much as the one you're using(or any nozzle).

I don't have time for a lot of reading and getting complex. I just know that I'll have 400-450whp so I'll need a nozzle that can support that. I thought that was the whole point of the controller so that nozzle size didn't matter. That's why I bought the kit.

If you want the 16 GPH its available. Our controller allows you to lower the flow rate, but if you need more than the injector that you have can flow, obviously we can make it flow more than 100% of its capability.

Our new kits ship with 1 large and one medium that will work with just about any car. 16 GPH will be more than enough flow for you.

Like I've noted b4, cooling makes it seem like their controller is so special that it will make a 6gph nozzle work optimally on any car. I guess he's banking on people who don't have the time to do a lot of reading. You my friend should get a free or trade in nozzle(at least imo).

<whistles to self>

Not that it can't be used well with more powerful setups, but more that a 6gph nozzle can be(it is imo) too big for regular wrx injectors and sti injectors. Like I was saying b4, you do not need a bigger nozzle, but you might want one if you're planning on maxing out 1000cc or bigger injectors(which you are not), or are planning on running a really high injection %. An m6 nozzle(the one you have) should push about 400+cc of injection at your systems top flow, and that is big enough to get a 10% or higher water/alc to fuel ratio on a car that maxes out 1000cc injectors. If you don't run more then 800cc injectors can put out(which I think you won't), you should be able to run 13% or higher water/alc to fuel everywhere in the rpm range(with the nozzle you have), which is generally considered enough.

If you decide to get a bigger nozzle and have 800cc injectors, ya might not wanna take such a big step up. Or you could just get a 16gph nozzle.

peace

Yeah I agree that the nozzle should be free also since when i bought the kit i was told that the standard nozzle will work. I have the same mods now that I did then.

I'll get this out of the car and ship it to you this weekend. The last couple weeks have been crazy.

Our manager said he talked to you over the phone today. keep in mind we may need a week before we can turn this around and get it back to you. We have to have it recalibrated which is a timely process. Thanks again.
