I am thinking of placing that new N-ter Cooler (the thing that sparys Nitrous on your IC) on My FD along with WaterInjection. I also have a set up that sparys water on My IC pipes to reduces the tematures even more. As well as on the radiator so I can drive it in trafffic. Im into the water cvan u tell. But anyway back to the question is it possiable to go too limiting out freesing the water injection. Lets say 35-40F will it hurt my motor or is it ok.

 

whoa!?! Could youpost the parts/places you got this system from! Id love it run it

 

Um Yes, you can go to cold. What kind of ECU do you run??? A member just blew his motor using the N-ter cooler, and other mods using a PFC. The stock intake temp sensor did not compensate for the extra cold charge (more dense) because it didn't react fast enough to add the extra fuel.
While it is a very good thought in theory, and I too plan on using something like the N-ter Cooler, it is very risky to try and do something like this without proper testing and tune time.

Good Luck.
