unfortunately for us here in socal getting a gt car for msrp is darn near impossible regardless of past relationship with the dealer specially when too many buyers are welling to pay the asked ADM to have the latest and greatest. Same dealer sent me a spec sheet of a loaded gt3rs that had just hit their showroom. I passed the info to one of my friends who is in the market for one. My friend stopped by the dealer 2 days later only to find out the car was gone for $30k over. The car didnt even last 2 days.

How does it work?
Injectors spray water mist into the intake manifold, which quickly turns to water vapor through evaporation. As the water evaporates the air temperature is lowered by about 80 degrees F. This is the same principle as your body sweating. When your body sweats, the water on your skin turns to vapor and lowers your body temperature.Cooler air also means more dense air. The denser the air, the more fuel can be burned thus creating more power. Vehicles at sea level take in more dense air than at altitude on mountain roads. The thinner air at altitude decreases engine performance. In aviation, many piston driven engine aircraft compensate for the thinner air at altitude by using turbos. The turbos literally ram more air into the engine to compensate for the thinner air and create more efficient power.

I am not sure what you mean by "intercoolers" but the idea is to spray enough cold water vapor into the "intake" manifolds to cool the air for improved oxygen content due to more compressed air; thus more HP. This concept was used in the 2016 M4 GTS (I have one in my garage) recently but really goes back, way back into the 60's...I believe an American car industry innovation.

As for injecting water into the manifold, that goes back to WW2 when piston engine aircraft ran water/meth ADI to control detonation at absurd boost pressures.

Here’s something interesting.
I was black flagged at my first track day in my GT2RS. They called me in and told me I am dumping fluid every time I exit turn 1. I asked how much fluid and they said about 1/2 cup. We scratched our heads for a while. The track was shut down so we could inspect the fluid and it was gone. At which point I realized the fluid was distilled water that was pooling up in the front somewhere upon braking after the front straight.
It was quite a relief, and they let me back out no problem. I also got my fjest low water warning that day! Badge of honor.
