N-tercooler fmic spray kit

Okay, I DID search already but, found a bunch of half assed threads that were never completed, or got off topic lol. Does anyone know how well this kits work? Better yet does anyone actually have one on their car? I know these kits are made to spray either Nitrous or CO2. Wouldn't CO2 be alot colder? I played tournament paintball for about 2 years and I know that we used compressed air/nitrous over CO2 for our guns because CO2 was too cold and had other downsides. Any input on this subject would nice.

I've had a couple of friends that have used it on there stock side mounts and they said that is was a very noticeable gain. But 52hp that seems a little far to even for a front mount.

You won't see much of a gain on something like a t-25 where your turbo is already pretty much maxed out as for lbs/min of air flow. so the only benefit there is going to be a slightly more dence air charge entering the motor. If you have a larger turbo like a 20g that you havn't been able to reach the maximum lbs/min airflow because the air charge was to hot and causing detonation then the co2 cooler would deffinetly give you a much larger gain.;) As far as numbers go, its going to depend on what your set up is.

I am sure you could google a couple of different gases and find out what temp they leave the bottle at to help you decide what you would like to use. Another intersting option I know the GN guys use are propane injection turbos.
