Hi,

has anyone tried NOS in the form of intercooler spray? Or possibly just using water (like Subaru)?

If yes, how was it?

If not, why not?

If it's what I'm thinking of then yes, there are people that have tried the NOS that sprays into the front of the IC. It provides amazing results, but it's not popular.

Im really curious in doing this as well

Is anyone on here running that set up?

Im nowheres near a NOS expert since Ive never had one on any of my cars but if you were to spray it on the front of the IC wouldnt water or alcohol do as good of job? It would seem that it would be better to spray it in the intake for greater gains. Then again it would probably mess up the IAT too much and trigger a limp.

Once again, I dont pretend to know much about NOS but these were my initial thoughts.

As far as making the car look stelth when going to the dealer, wouldnt an NOS system be time consuming to remove and re-install? I know my IC is but Im not so concerned about that since they arent known to be the root cause for blown engines.

NOS, since it is pressurized, has a much higher cooling effect than water or alcohol, so the hp increase will be much larger. Of course, spraying into the intake or cylinders directly provides a much higher increase in power than intercooler spray, but I would consider intercooler spray safer.

NOS is not something you would have on a put-on/take-off basis. But, I don't see how the dealer could actually void your warranty, since you are not doing anything else than operating the car (albeit with the intercooler at a lower temperature than its surroundings).

This is an example kit: http://www.watsonperformanceproducts.../Detail?no=749 (just so we know what we are talking about, if this is a violation of any rules, mods please delete link)

EDIT: Here is a test in Honda mag http://www.hondatuningmagazine.com/t...est/index.html , so you can judge how much power this will give you.

Water is more effective than NOS - at least when cooling the intercooler.

What you care about is latent heat of vaporization, which is effectively how much heat is required to change the liquid into a gaseous state. That's a measure of how much heat will be absorbed.

Plain water, if you mist it lightly enough, requires roughly 2600 kilojoules / kilogram. The key is that you must MIST it, not douse the intercooler. If water is running off the intercooler, you're not getting vaporization. So the STi sprayer basically sucks. An analogy is that it is relatively quick to boil water on the stove, but takes a while (tons of heat) to turn all of that water into steam.

NOS, despite the Fast'N'Da'Furious'YO! rage, isn't that great for this application. Its latent heat of vaporization is only ~375 kj/kg. That means it's less than 20% as efficient as water in cooling your intercooler.

I've done the misting system, with water. It DOES reduce logged IATs, but it's a pain in the butt to install and a pain in the butt to use.

Hm, but I thought that the NOS system will decrease temps lower, while water will take longer to evap, so not reducing them as much, but for much longer?

That's why you MIST it, as I said before.

If you atomize it properly, it will evaporate on contact.

[JoeyFiasco]

is this something you could use everyday or just at the track?

[dlbrooks18]

who out there is running this setup? seems safe enough by spraying the intercooler. the snake design kit looks promising. reviews, please..

[ragingclue]

Someone dyno'd with one of these a while back and got some staggering results. Came to find out it was getting sucked into his intake, basically turning into a dry shot.

Larry aka oldbooster from N54Tech.com currently holds the record for the fastest 135i 11.76@119..he just installed that same kit on his car hoping to go faster..he actually ran out of nitrous in testing it out.He should be hitting up the track tomorrow with a 10lb bottle.Car should go faster..11.50s ? 11.60s ?

[ar design]

Put the nitrous in the motor. Way better results The N54 LOVES the bottle...

[shifterboy45]

hmmmm.

forced induction
increased i/c efficiency
+10:1 compression ratio
add an oxygen enhancer.....
= increase combustion chamber pressures

i wonder how much will this little open deck block handle before expanding a liner and .. well you what happens then

sounds like sooner or later --

have you tried that ?

I think he was being sarcastic. Hence the two "winks".

No sarcasm here. N54s love the bottle.

care to share with us some specifics ? ex : kit,nozzle,jets,whether it was on a tuned car or not.

High compression and boost and juice? For some reason I think think thats the healthiest for the internals, haha. Im sure it makes power though.

When setup correctly, its just fine. 50 dry shot, with our ESS flash it actually ran a tad richer on the bottle thanks to the tune compensating. We have a nice little kit available if anyone wants one

meth ftw

Can you post or PM the details/pricing for your kit?
