Just my opinion and tastes. It's your car do what you like. It will definitely help performance. I like the clean look of just an intercooler through the opening. IMHO the bar breaks up the nice look of a large intercooler. This is the internet we don't have to agree. I don't mean to offend anyone. Sorry if I did.

In addition to all that it DOES work, im just not sure how well!!

That is interesting....45 HP increase from cooling the IC....sounds worthy. I bet you consume a huge amount of N20 in the process though!

As far as the question from the pearlcoupeg35,

a nitrous system doesn't produce the majority of its power from the colder air charge. That is a side benefit, but far from the concept behind adding N20 to a car. The purpose of adding n2o is to take advantage of the extra Oxygen atom. Nitrous oxide is far more oxygen rich than AIR. During the combustion the process the oxygen atom separates from the nitrogen and is consumed in the combustion. Extra fuel is added to keep the A:F ratio in check.

DJ, no hard feellings. everyone's entitled to their own opinions!! Thats the beauty of living in the US. His car is FI, therefore the NX I feel would 'only' benefit him, however as most have said there are cheaper alternatives (CO2, etc). Here's a G I found w/ FI and the N tercooler kit...

In my opinion it doesnt 'really' take much away from the FMIC, as its a small ring thats barely noticeable...

It's a trade off because you have to fatten your fuel curve to take advantage of the intercooler being chilled. richen the mixture-lose power just to get it back with the nitrous. had it on a turbo'd gs-r. worked great on hot days when the car would feel sluggish from the heat. you could also refill with CO2 which was cheaper.

I think the sulphur is added so people don't huff the chit.

You spray the intercooler just before a run not while you are running.

Great mod. You'll see good results. Its totally not rice. This mod is more economical and smart to use . It costs less than regular nitrous kits and it will not create engine problems that the nitrous injections kits can cause. COLD air is goooood!!!

The elliptical ring will hardly be noticeable to other people in traffic, IMO, so I'm not convinced that it will look rice.

That's why, in our case (PE TT), you hsould think about moving hte intakes down into hte wheel well area (like i did). I posted all this in teh FI forum a couple of weeks ago. Check it out.

Have fun! Take pics and dynos and track times!!!

UNREAL
That's exactly what it does, its honestly amazing and makes a HUGE difference on warm, hot, even cold days to make it even colder LOL.. It also makes up for robbed power from heatsoak, here's mine and to those who say its "rice", like wtf, are you being serious right now? Those are ignorant comments !

all this yappin about cooling your intercooler with n2o.

imo its a waste. i'd rather do a progressive alchy injection kit and be done with it. extra octane and icy intake temps yay for more boost.

just my opinion though

LOL, im one step ahead, i also have water/alcohol injection for cooling purposes

I have the same kit still in the box...Let me see if I can find the instructions and send them to you...PM me email.

I have the remote bottle open and the full pedal kit too...so you open, arm and it sprays at FT.

PS use CO2 in the bottle...WAY -$$$...and same cooling properties.

This is the CO2 kit my friend is using on his car. I like this system simply for the co2 benifits without the possibilty of any N2O detonation problems. Just a thought.

ok I dynoed my car a last month and it made 45 hp more when we took a bottle of N2O and sprayed the intercooler on a run. SO YES! it DOES work very well if you cool the intercooler.

I have the front ring installed with the solenoid and the line but I just can't find a good place to put the bottle. Any suggestions? I tried to mount it to the folding seat but its a heavy bottle and not easy to bolt down to the seat. ANybody got pictures of their setup. PLease PM me!!!

did you check the boost and air fuel when you dyno'd the car with the n-ter-cooler? most like the cooler denser charge leaned out your ratio. beware of that when boosting with the system active. unless you have a piggyback with switchable maps, i would leave a system like this alone. i was told by my intaller i could fatten the fuel curve to compensate for the denser air being introduced or just lean the motor out a little for more power. an ideal setup i think would be to have a system that will add a little more fuel when you use the system. i kept it on my gs-r because i was going through my fast and furious phase. it's a nice system that is very effective when used corrrectly.
