How much meth are you spraying and where do you inject. With my small shot of 50/50 9gph nozzle pre throttle body my IAT2 doesn't really change much more than it did before. My IAT2 is a dedicated sensor read on NGauge through ZT-2 system somits real accurate data.I run my water meth setup as a IAT cooler only. At 20+psi of boost i was seeing real high IAT's very quickly. Now I can watch it drop below ambient during a run.
I have my sensor divorced and installed at the very back of my intake so I should in theory see the hottest temps.
Where do you inject?I have a dual nozel setup. Can't remember the gph at the moment, I want to say they are each 16gph or 19gph. Pretty sure they were 16 because if I went to the dual 19gph, I needed a twin pump setup. I shoot for a higher 49/51 meth/water mix, but i'm sure it closer to 40/60 because I error more on the side adding more water.
I spray 6" before the throttle body.
