With the car in motion most of the spray will either heat up or pass through the intercooler or even worse not even hit the intercooler. Which means it will have minimum cooling. I agree that there will be some effect, but I would be amazed if it produced anything over 5 hp. Now on a dyno where there is no wind and the car is stationary you could probably get a good gain by spraying a mass quanitity onto the intercooler.

I am not saying that a system like this couldn't work. If you sealed the back side of the intercooler and put up side deflectors and continously hammered it with a lot of NO2 you could see a lot better effect.

IMHO, there are better ways to use your money to increase performance.

 

It is a waste of money because it DOES NOT provide the advertised 50 HP gains when done properly and is dangerous because while they MEANT to spray it onto the intercool only, some ACCIDENTALLY got into the intake and caused the gains (as well as a lean condition). I explained this in an earlier post. It isn't hard to understand.

Have fun refilling a nitrous bottle every 5 runs down the strip or every minute of spray time for 5 Horsepower.

It's about common sense guys, not what your friend with a Trans Am says.

 

yes, this is correct...the gains are seen on a dyno due to the n20 or c02 mist travelling up into the engine bay and into the intake...since the car is stationary, the gas travels upwards...which can be very dangerous...

when the car is in movement, you will not see the gains you are talking about...if you REALLY want to get some gains like this at the drag strip, try dry ice on the intake mani...youll probably see the same numbers as far as times and traps, but you wont be spending hundreds of dollars...or get a spray bottle with ice water in it and spray your IC in between runs...but as far as a 50whp gain, i just dont buy it...if that were true, every turbocharged car would be running this setup and you wouldnt be having to ask about it

 

your right it would be real hard to hit the intercooler considering it is mounted on it

 

my buddy didnt just say a half second, he dropped a half second on the track. so the car is in motion so the co2 cant travel up the intake right... and even if it went though the intercooler it is still a half second no matter how you look at it.

ps co2 is non-combustiable gas so it wouldnt blow up if it got in the motor.

 

Ok dude, whatever. Report back when you get it installed and let us know how much you picked up. Just know that you can gain .5 in the 1/4 just by driving a little better or even just by improving your 60' time by .2. That is easy. You can also dramatically improve your 1/4 mile time by running in November compared to July. The fact that your buddy says he gained .5 from a mod means absolutely nothing to me. What happened to his MPH in the 1/4? Let me know how much that changed. Then let me know the two dates that he ran. Then let me know other changes made to the car between the runs. In fact, if you can, post the time slips. I will tear your 1/4 mile time argument apart. Please humor me.


BTW: CO2 is a nonCOMBUSTABLE gas so if you inhale it into an internal COMBUSTION engine you will lose power. Face it, this is a stupid mod and a waste of money.

 

didn't buschur or somebody test this a while back and conclude that it only works effectively if you fill the bottle with nitrous? hence what was said earlier that you would get a little shot of nitrous in the air intake and could be harmful to the car.

btw a friend of mine used this system on his sti and only got a small hp increase on the dyno. his trap speed stayed relatively the same.

 

if youre going to sit there and argue that the system is good to everyone that says its bad, then why did you even post asking about it?? just go get it if you are so convinced that it works

 

Okay, I'm not a scientist, but I am a skeptic. I have the NX N-Tercooler on my car. Because I didn't believe it would work, I put it on and ran it on the dyno, with and without the device activated. The bottle was filled with N2O.

Here's the graph:



Now, if I do my math right, you should be able to get at least 25 hp by cooling the intercooler down to sub-freezing temps. Assuming that's right, perhaps I got 23 extra hp by snarfing nitrous into my intake. The car has an open-element filter in the engine bay, so that's certainly possible.

Regardless of whether or not it's sucking some nitrous into the intake, it clearly made some big power gains. I DID have an air/fuel probe stuck in the tailpipe, and it barely changed between runs -- about a 0.1 change (leaner) in the air/fuel mixture. Certainly nothing to scare me, and that could be explained by the cold intake temps alone.

My verdict is:

- It works. I don't doubt it works on the street, regardless of speed. The liquid gas pours directly on the intercooler. Although I haven't recorded any data on the street, you CAN feel the power on the street.

- It MAY work partially because of inhaled nitrous. I didn't repeat the test with CO2 in the tank, so I can't really quantify how much.

- The intercooler DEFINITELY gets quite cold. It was covered in a thin film of frost during the dyno run.

Some other notes:

- It consumes LARGE amounts of gas. Figure you'll get maybe 30 seconds of solid use from the tank. Maybe 2-3 dyno runs, 3-4 drag passes, and you're done with ten pounds. Not something you'd want to run all the time, and forget about using it for, say, road racing. Unless it's just for that final lap sprint.

- The kit isn't much money, but install is pretty elaborate. It's like installing a "real" nitrous system. There's the bottle to mount, plumbing to run, wiring, switches, the fixture on the intercooler...

- It's a total attention getter. Any car event I go to, people recognize the thing and ask about it.



- On a car with an open cone-style filter under the hood, I do NOT recommend using CO2 in the tank, because sucking up CO2 will INHIBIT combustion in a big way. Just in case, I'd rather have something that will HELP if some stray gas gets in there. CO2 is about 1/10th the cost per pound, though.

I think it's a pretty good value in terms of horsepower/dollar, but keep in mind it's a very short-term hit, and if you're going to run nitrous, that's $50+ per tank fill up. Some people buy this kit for the "wow" factor. Some for the power. Many seem to like both parts of it...

Oh, and in terms of the health of the car...I've run a couple of bottles of N20 through the system. No damage that I can perceive. The car still runs strong, no problems. The motor definitely did not explode, nor do I expect it to.

I sold mine before I installed it....water and alcohol are enough IMO

 

Sounds good. Too bad only 4 runs. Sounds like a hasle to refill all the time. Great for the track though.
