i am looking at the water injector kit at urd. has anyone installed this unit? i am wondering if it is neccissary at all. i have a cold air intake on it, i know the manifold will still get hot but hot enough to rate one of these, i dont know. maybe some one can explain. my set up when complete will be supercharged with a genIII, cold air intake, port and polished heads, header w/ cat back exhaust, and the fuel system from urd. i might possibly rebuild the heads and put diffrent cams in. what do you guys think!!!
