Hey guys,
I searched all over the forum but didn't find anything about the NX Ntercooler. Does anyone have it on their turboed civic? I have been thinking about getting that as my "new thing on the car when spring comes" thing.
It is $599 from NX and I know that the VW's have been putting it on a lot of their Golfs...
Anyone know anything about it for us?
Melissa

look for it on ebay sotre they have em for 499 i think...

you put it in front of you intercooler and it sprays liquid nitrous which is -30 degrees F.... some dynos have shown it to gain as much as 40 hp with just this mod... call around and see if you can just get the spray rain by itself... it's cheaper and all you need is the silonoid the bottle and some nitrous line...

his isnt' the NX ntercooler but a different brand.......does the same thing though.

i always wondered though, since u are spaying n2o or co2, will that harm ur engine if u are running high boost on a stock motor.

Its actually C02....FuterRSX's is called cryocool....you can see them on ebay for a while. C02 is expensive in general, but relatively cheap when compared to everything else. It actually does work. The theory behind the use of the intercooler is amazing - considering that the compression process of the turbo is supposed to raise the air charge temp to around 200 degress or something. So yeah, cooling the air with C02 will add HP to your car, but only pretty much for track or drag use, you don't want to do this on a constant basis or I'm sure you'll thermally stress your cooling fins / tubes (which means they'll eventually crack or something)....

I tried the system, ended up sucking a lot of nitrous into the engine, causing a lean condition. Probably could have used CO2, but decided to just sell the system back instead.

If you use CO2, probably OK, but if you're using nitrous, you'll have to find a way to compensate for the added nitrous with fuel, and theres not a way to do it because the amount you will suck in is such a variable amount.

Just run a 50 shot into the motor, better results, safer, and you'll still have just as cold temperatures.

Hey RSCivic....I just read your profile and it says you are making 183 HP?? How much are you boosting?! I made more than that on my 75 shot of nitrous. You have a lot of mods, so u must be at pretty low boost??

I think it depends on what is "low boost"- I think that so far my dyno is on of the top dynos w/ the basic SF turbo kit (Catalyst excluded).
This dyno was w/ 8psi. I was running 9psi before that. I have the basic SF kit- no alc injection no upgraded turbo.
The thing that I am happy about is that it is really hard to get higher torque than hp on a Honda. My boyfriend has a supercharged v6 Accord and dynoed 266 hp but only 216 torque.
That is why I want the ntercooler. I think that with that, plus getting some head work I will be happy with what I have.
It is pretty cool that there is another chick on the forum that knows about more than just wheels or window tint- I think that sometimes people think us girls don't know much about cars- until we spank them!
Let me know how your turbo set up is coming-looks like it is going to be a good one!

Hrrm ok!! Thanks for the answer. You're right it is DEFINITELY nice to know of at least one other girl on the boards that's concerned moreso with how to make more WHP And knows her stuff!!

AND, You're right. It is definitely not common to see a higher torque than HP on a Honda. That's why I was ecstatic to see my 185WHP Dyno w/ 209WTQ (on the 75 shot). Gotta say, I wasn't the only one that was surprised by those numbers.

I didn't realize that you were not running the alcohol injection. Somethin about an extra injector in my charge pipe and alc. injection doesn't sound right to me. Not right as in it doesn't work, it obviously does, just not the way I'm used to doing things/seeing things.

I'd definitely like for you to keep me posted on your progress!!
If you do get the Ntercooler....and dyno test/tune let us know!!

CO2 is colder than nitrous and will produce more hp because of the added cooling but it's not such a good idea because like riceburnerex said, he sucked up a lot of nitrous which caused him to go lean...

CO2 for you chemistry buff's out there doesn't like to combust and it actually cancels out oxygen when injested into the engine causing loss of hp....

i think with a little fuel tuning and the nitrous spray, you would get some nice gains with it because of the fact that not only are you boosting, but you're actually using a small shot of nitrous as well...

 
Rep Power: 606

yeah, but how hard is it on the motor with a stock bottom end?

I mean, is it dangerous to be running around 8psi and spray the ntercooler vs. a 35 shot ?

 
Rep Power: 0

it's not being sprayed directly into the engine like a nitrous kit... it sprays liquid nitrous oxide on the intercooler to cool the temperature of the intercooled air even more...

RIGHT... so how the **** is there NOS or C02 getting into the engine with rice burner? that doesnt make sense... WHAT ITS BLEEDING threw the METAL? i dont get it .. why is it getting into the engine.. its not supposed to ... that sounds like a leak in the IC...

IF the spray is getting in when u spray on the intercooler then why isnt water getting in my engine when i rains...

im very confused on the whole NOS getting into the engine issue if ur not spraying it in the engine only on the intercooler...

Yeah that really doesn't make any sense, I agree...

The sprayer is in front of the intercooler... sprays on to the intercooler... toward the back of the car, while you drive forward. Guess what's behind your radiator somewhere? Your air filter. Sucks in the nitrous just as it sucks in the air. Unless you've got a seriously relocated air filter (above the hood for instance), you get your air supply through the radiator. Moving the air filter down to where most cold air intakes are would work, if you want to run the risk of ingesting water from puddles. You can eliminate this by only spraying before you launch, but this has a very limited effect on cooling since once the turbo spools, the intercooler heats right back up.

ok sooo what if u got a filter like say numbers 42 06 09 10 40 and 04 ?
i mean i duno where urs sits but if i did that id be more then fine...

not to mention your air filter sucks from in front of the tranny if im not mistaken.. mine points the other way.. SF kit should be fine with it imo.

I would be interested to see what type of gains someone could get with this type of kit.... The WRX guys seem to be using it everywhere and I think turbo Civic's could benefit quite a bit with the proper tuning... Combine it with SF's injection kit (would it even work?) and think of the boost numbers and whp people could be running on stock bottom ends.... Sounds very interesting....

My air filter is where the tranny and the block meet, which is why I was able to suck so much in. If the filter was elsewhere, then you'd probably suck less in. Easiest way to find out? Put the sprayer on your car, use a wideband o2, and find out if you're leaning out or not. If you're not leaning out, then happy spraying.

By the way, the intake air temps dropped from 106F to 54F while spraying... so the product does work.

i spray the co2 before i even launch so it doesnt get sucked in duroing driving, it turns the intercool WHITE... cold as HELL... works in my opinion, but only helpfull on hot days.. LOL... i hate nitrous so i would never try that out..........

i HATE when i forget sig....

Yeah I don't think that you ever should spray after you launch. It is funny b/c a lot of people think it is nitrous, not something to chill up the intercooler....

 
Rep Power: 0

Spraying before launch does help on a hotter day, but it's not nearly as effective as spraying while going down the track or street.

We played around with this as well, if I iced the intercooler over before the run, the intake air temp would be lower until about the 1/8th mile, and then after that, normal intake air temps. Did help my 60' times a very small bit, and didn't affect my a/f ratio at all because I wasn't spraying down the track. If you spray down the track, or spray at multiple points on the track, such as before launch, at the 1/8th mile, whatever you decide, your intake air temps will be lower throughout the run, not just at the beginning.

There's an EVO here that loves the system, he sprays going down the entire track and it helps him more than just icing down the intercooler before the run, but also uses a TON of nitrous. Can only get in 2, maybe 3 passes out of a 5lb (yes, it's small) bottle if he's spraying the entire way down the track. His air filter is located where he sucks in very little nitrous if any at all, so he has no problems using the system.

These kits are intended to spray while going down the track, according to Nitrous Express's tech support and by the fact that they include a wide open throttle switch. They wouldn't include that if they didn't intend the user to spray while going down the entire track.

Very very true. If you're not spraying the intercooler while running the track you're not getting the most of the kit....
