Nitous InterCooler Cooler!!!

has anyone used nitous on their FX stock engine. What are the results???

When I was at Shawn Chruches shop on the Dyno Day, the guy from Nissan Magazine suggested that I get a Intercooler (IC) cooler. The company DEI make a system called CRYO2 which consists of a Tank filled with CO2 Gas which is piped into a Ring that is installed on the IC. Using a Switch, it sprays CO2 Gas on the Intercooler which dramatically reduced (almost freezes) the air going though the IC which will drop the AIR tempreture going though the IC. They also have another Option that has a Ball inside a 3" Intake Tube which CO2 passes though which subsiquently reduces the air that is going though the Intake tube.

The problem with CO2 (Carbon Dioxide) is that it replaces oxigen (deoxidizer) which is needed for Combustion. If CO2 comes in contact with the AIR that is entering the engine, it reduced the Horsepower since it's reducing the amount of Oxigen.

On the Other hand, N2O (Nitrous Oxcide) has the exact oposite effect. N2O is a non-combustable Oxidizer which elevates the amount of Oxigen as well as having the same Temp reducing caracteristics. Nitrous is used in Combustion Engines to produce high levels of HP due to these caracteristics. Usual application of N2O in race engines is direct injection of the gas into the intake or directly into the cylinder head.

If not used properly, N2O can kill an engine due to generating extream heat levels that is caused by bigger explosions inside the cylinder chainber.


Now My Questions: The Same CRYO2 system can be run with nitrous instead of CO2. This means that IC can not only be cooled while engine is idling, it can also be used in higher RPMs without the Oxigen robbing efects of the CO2. The Problem is that how much of the N2O will get into the intake and what sort of problems will it cause for the engine.

I would imagine the resedues of either gas getting into the intake is not that much to cause a concern, however, I do not want to take any unwanted risks.

CO2 is effective enough to cool down the IC before runs, but N2O is effective before and during. Since the Port hole for the Intake is very close to the front of the FX Engine, I'm concerned it might put too much of one or the other into the intake.

Anyone has a different oppinion or experiance?
 
It has been a while since you post this but i was looking into the Cry system as well and was wondering if you got this system or not and what your experiances where.......
 
I had a Nitrous Express intercooler chiller on my Maxima (not an FX, but a VQ30 so in the family). Gains were there, but negligible. It is not something worth buying in my opinion, I had a sponsorship deal with them and so put it on along with a standard single fogger kit. Both nitrous and CO2 aren't that cheap, and spraying it onto an IC isn't an effective use. I would say that buying a meth kit or just spraying nitrous the regular way are better uses. It does look cool, but that's about it.
 
While I have never used one of these systems personally, I have to agree with shadow. A system like that should be used (in my opinion) on higher horsepower cars (700-900whp) to protect against detonation by bringing down the intake charge. Water/Meth injection does the exact same thing, except it is sprayed into the intake charge. I would choose Water/Meth, then I would choose Nitrous - direct port injections, then only as a last resort I might consider an IC spray kit.

Water/Meth - Chemically cools intake charge
Nitrous - chemically cools and adds oxygen to the intake charge
IC cooler - physically cools intake charge

For the power levels your build is aiming for, I think an IC cooler system like this is not very beneficial. For me, the value is not there for the initial investment and upkeep (CO2, NO2, Water/Meth) plus maintenance and failure safeguards.

If you finish your build and find that you have knocking, pinging or evidence of detonation under certain circumstances, THEN I would consider a system like this to add insurance against those issues if it is appropriate.
 
Not on the FX specifically, but I did run nitrous for 4 years and then boost for the last 6 years in separate vehicles. You can use nitrous to cool the intercooler as demonstrated by many of the early sanctioned import racers who were already running nitrous to compensate for their turbo lag. However, they always have to be very careful in avoiding accidental nitrous ingestion which would lean out the engines. The gain from this cooling method is small but when you're competing for big money, prizes and fame every HP counts.

For street and non-race vehicle, this is impractical as a long term solution. Depending on location, nitrous is $3-5 a pound and CO2 is around $1-3 a pound. If reducing intake air charge temp is your goal, then I would consider a larger IC (space allowed) or a more efficient IC option first. If you're running low boost then parasitic losses through these suggestions may not be worth it, imo.
