ok, i'm not running NOS into my engine, just to the intercooler like the CryO, and I'm filling my bottle with CO2 because it's a buttload cheaper. The problem is that I have no idea how to run the tubing through my car, hook up electrical switches, plug what into what, etc. Basically, i don't know anything about it. If someone could link me to a diagram, or just give me a detailed explaination, it would be very much appreciated. You guys know everything, thanks in advance.
You need the regular nitrous basics like the bottle, SS line, fittings, solenoid, wiring and controlled by a direct switch or something like a Hobbs(sp?) switch. It automatically engages when a certain boost is achieved. IMO, if you are going to go through the trouble and expensive of buying and installing all the parts, you might as well just spray the nitrous. It is seriously very safe and will give a way more charge cooling effect than a spying system ever would. Just my $.02
Oh, and I just installed mine, and I had to run the line inside the car (seriously didn't want to do this) but subaru designed the car to have nothing indeoedantly attached underneath the car. I ran the line from the driverside of the trunk, under the support bar under the back seat, under the passenger side molding parallel with the fuel lines. I drilled a hole in the fire wall and put the line through a rubber grommet. Tedious job, but the time you put into it reflects what the end product will look like.
garcia, what do you mean just spray the nitrous... that's insane...
spray the CO2, at a welding supply shop its less than a 1/4 the cost of ntirous, and cools equally as well as any compressed gas... CO@ from a 5 lb bottle sprays at -100 F
You'd be a fool to use nitrous to cool your intercooler instead of CO2, not just for shear price difference of the two, but also because a bottle of nitrous in your trunk is like holding a large bomb in your car.... the bottle implodes/explodes get punctured, your letting lose a very volatile/flammable gas along with it... do you really want to burn to death after recieving the shrapnel wounds of the exploding metal bottle?
The CO2 if anything will put out a fire in your trunk because it chokes and retards flame... so if the bottle explodes, etc, the gas at least cannot ignite and explode into flames...
And my CO2 system is run out a small hole drilled in my trunk floor and attached at numerous point under my car (strategically placed to stay away from the ground and then up to my engine... so there is not real need to put that line in the cabin of your car... you sure don't want to be breathing that stuff if it should leak into the car... either you'll get high from the nitrous while your driving and crash... or you'll pass out from the CO2 and crash... that would be bad

lmao I was just about to post that very same thing. N2O is not flammable. CO2 can explode every bit as easy. the reason that it can blow up is from pressure not because it is flammable. Any pressurized gas can blow if pressure levels are too high to contain.
ever heard stories of pressure cookers blowing up?
sorry about the rant but that is such a misconstued myth.
the blow up risk is the metal of the bottle exploding from pressure, i realize this... AND that anything pressurized can explode, just thought that the nitrous would be also flammable in the explosion because it is typically used with the fuel to create more power. Is it not burning inside the engine chamber when combined with the fuel and air??? otherwise what point does it serve??? If not, how does nitrous create such HP? I always just figured it burned faster are stronger than gas and that was why people used NOS to get their cars to go faster... guess i'm wrong...
No, but it's an oxidizer just like oxygen (only more potent) so it's an accelerant. Needless to say, that means if there's any sparks or flames around during a crash or accident and that bottle breaks, you're only going to have that much bigger of a fire or explosion.
Well i have heard many things about thoes intercooler sprayers.. some people say that the gains from it on the dyno have been the intake sucking up some of the nitrous that was sprayed on the top mount.. it isnt too good of an idea if you ask me.. the air goes through the maf then works its way to the intercooler and if the intercooler is at -20 the air is getting very dense.. soo it is throwing off you air fuel.. its not the same as if it was dense air entering though the intake if that was so then the maf could add or take away more fuel.. if you are not getting a custom tune with the intercooler sprayer.. you are wasting you time and money..
on that logic, any modification to the stock intercooler at all would create the same effect... The MAF was originally designed and ECU originally programmed to run with the stock intercooler and its normal capabilities... But we all upgrade our intercoolers to ones that are much more capable than the stock version and the MAF is never able to make up for this since it comes first in the system... The colder your intercooler, the more performance you can get from your car, bottom line... This is why we have UTEC's in our cars to make efficeint use of other than stock parts. Certianly a dyno tune on CO2 would amke the best use of it, just like a dyno tune with stage 4 components would make more efficient use of them than if you just ran a standard TXS stage 4 map... Bottom line is this though... if you're running 19spi and its 85 degrees outside your car should be less likely to knock if you spray some CO2 through the intercooler between 15-19psi and WOT than if you don't... However,I'm pretty sure that colder intake temps will allow for higher boost levels to be achieved more easily, but we are just trying to cool the already boosted air once its been heated along in the process... So the question is...HOw much can the MAF really do with a stage 4 system, CO2 spray or not??? The MAF interepts atomosphere air temp, then the turbo compresses and heats that air, spreading it out (making it less dense), then an aftermakret intercooler cools it back down, effectively allowing it to scrunch back together... So by the time it enters the intake manifold, how can the MAF have any clue about the density of that air anymore since we've modified so much along the path of this system? What's one more little air cooling helper going to hurt? CO2 spray serves exactly the same purpose as a large front mount intercooler, or large top mount intercooler... it better cools the turbcharged, superheated intake air, that's all it does.
