Forgive me if this has been asked and answered, a search revealed only stuff on their spray bars...

Does anyone have any experience with or insight on this product? On the plus side it seems like it would be more effective then an intercooler spray bar as it is directly in the path of air flow, but on the other hand it seems like it would be a huge intake restriction. They claim a 50 deg IAT reduction. Thoughts?

 

i looked at this a couple of years ago when it first came out (i think), but i couldn't find much data on it to support their claims. I ended up just getting a water meth injection kit

Have you looked at other car platform forums for results?

 

Google search results in mixed opinions on different car forums... Some swear by them and some say they are not worth the money.

For most applications I would probably agree with the latter opinion, but having a turbonetics kit, lowering IATs has become a priority.

Another good question I forgot to ask would be if this would provide any benefit at all when run in conjunction with water injection - since I will be adding an injection system for sure.

 

i looked at the site and it shows they have a intercooler sprayer which i think would be a better option. Should be almost as effective as say Nitrous Express intercooler sprayer (w/o the risk of sucking in nitrous through the air filter)

 

dei makes quality products and their whole system is stack-able,they also have a fuel cooler that can be used in conjunction.

 

very intertesting, i know dei is a reputable company and all. I wish someone could chime in on this.

great for the summer season.

 

you don't have to run nitrous through a nx intercooler sprayer you can also run co2 it just doesn't work as well as nitrous. but i doubt you really end up sucking in much nitrous anyway but the nx works for both like the majority of them do

 

Not sure exactly how that works but I have to assume that the system pushes the CO2 through that tear drop shaped object and that is how it cools the air. I would think an intercooler sprayer would cool down your intercooler which has a much larger surface area and would be more efficient at cooling your intake charge.

 

I personally wouldnt want to place anything that large into my intake tract. I don't see how it could be any more effective than straight water/meth injection, either.

Give it a shot if you really feel like it, but I wouldn't have high hopes.

 

Thats what i was saying . DEI makes a CO2 intercooler sprayer.

I wouldn't be willing to risk using a nitrous sprayer on my car though. Not sure about other tt setups by my filters sit on both sides of the intercooler so it is almost in the direct path of the sprayer

 

+1, mine is directly above the intercooler...

Taurran, I agree completely as far as it being a big obstruction. DEI claims it makes no difference, due to the shape of the bulb. I just don't see how its possible that it doesn't create a bottleneck though.

Well I am really just looking for any way possible to lower my IATs. I am definitely going with a water/meth injection system within the next few weeks. And I plan on getting one of those lace up charge pipe insulator sleeves, which in conjunction with my ptp turbo blanket should prevent most of my charge pipe heatsoak.

I'll be back on the dyno at PRE in July, and if I can hit my power goals this will be a non issue. If not I will be back looking for alternative solutions, including (but not limited to ) the idea we discussed, Taurran.

 

Anyone want to try it, just let me know. I picked one up and never ended up using it.... Practically giving it away.

Did you ever run this thing? Did you do the intercoller mount or intake tube?

I was wondering when using it with the intake tube adapter with that bulb gizmo, you think it should be installed behind or in front of the MAF sensor?

What I'm wondering is what would happen when you freeze that bulb thing up and the frost on it melts. The water droplets will go straight into the intake. Seems like if it got on the MAF sensor it would fug it up, so maybe behind would be best?

Would that small amount of moisture cause problems or would it be no worse than the vapors that go into the intake from the oil breather tube?

 

what moisture dude? are u driving in puddles or something? I mean think about it...u have an air filter, an intake pipe leading air into the throttle body. where does water come into the picture....unless u are talking about a water injection kit before the dei intake cooler. Maybe then it would be a consideration. But if that were the case I wouldn't be using straight water.

 

The demo I saw on a setup with the intercooler sprayer bar is that the sprayer bar gets cold enough that it gets a coat of ice/frost on it.


Since that setup is mounted in front of the intercooler the sprayer icing up doesn't matter.

While using the bulb/intake tube setup the bulb will ice over. When the frost on the bulb melts it's more of an isssue than the sprayer bar setup, since any moisture will be in the intake.

Thought I was clear enough.

 

The bulb will only get icy if you introduce water to the system. Otherwise the CO2 is passing inside the bulb. That would make only the bulb get cold. Then as air passes over and around (outside) the bulb...theoretically it would get colder. I am not a proponent of the bulb theory as much as the intercooler spray bar, but as many have stated DEI is a reputable company so it must have a benefit...even if it 2% it is still a benefit.
I have seen people at car shows with multiple bulb adapters...1 before the intercooler and 1 after which IMHO would work twice as good as just 1. But I still vote for the intercooler spray bar as my first choice (of the DEI products).

Just my 2 cents.

 

There is moisture in the air passing over the bulb. Therefor it is completely possible for frost to form on the bulb due to the dramatic and quick drop of temperature which could freeze the moisture (humidity) in the air.

Two of them in a row would not be twice as effective unless the first one was uneffective. The reason is that if the first one does in fact do what it is supposed to, by the time the air gets to the second one the differential in temperature will be dramatically less then the first one since the air should already be cooled.

I would personally go with a intercooler spray bar since an intercooler has drastically more surface area than this part does.

 

we actually tested them out on two different turbonetics setups trying to get the AIT down. when we sprayed it on both cars, the cars lost 50 -60 hp and made a really weird graph. we tried to figure out why and then realized that when it sprayed it onto the IC, it would travel up and get sucked into the intake. we moved the intake so it wasnt close to the bar and it worked better but no way was it worth the trouble for what it did...

 

Nitrous belongs in the engine worthless as IC sprayer the only reason u see gain on dyno is that the stagnant N2O fumes are sucked up the intake. Also Co2 depletes oxygen so why would u want that any ware close to an intake.

 

+1 nice first post
