Installing meth today..is this an ideal place? 
The IAT is already installed in this location(in yellow) and I was thinking about placing the nozzles on each side of the pipe(in red) as shown in the picture. They are 2 M7 nozzles, so they should atomize really well. I figured this would be far enough back to cool the incoming charge, and also register on the sensor so I could add and pull timing with the temp change. I didn't want the nozzles too close to the IAT. Also, I will be running a 33/66 meth/water mix(1 gal of M1 to 2 gal dis.water)

Yes. Im using 2 small M7s at high pressure. You don't want to get too close to the intake manifold(from what im told) because you wont have equal distribution to each cylinder. Plus having them further away allows the meth/water to cool the intake charge air.
Best is always debatable but here is what one company has on line

I put mine a lot closer to the TB, it works for me hope yours works good for you

Tried it tonight and it works great. Temps and AF dropped really quick. I have it set through my boost controller to turn on at 9.7psi. Immediately the IATS dropped along with the AFR. Im going to do some tuning tonight to see what I can get out of it. The owner of the company I bought my kit from said putting it before one 90* would cause no issues. Also where I have it, the meth has more time to better cool the intake charge coming in.

That makes sense. At first I wasn't sure if it was working. The temp would start to rise sharply(as usually) then level out(not normal) and as soon as id let off the throttle the temp would drop hard.
A friend swears mine isn't working and only 'fooling' the IAT sensor. I believe it makes the air denser (cooler) and helps prevent detonation (octane). As for how much, I push where I would without and feel that leaves me some margin.
Especially if the meth fails I shouldn't melt. With boost you never have enough margin, but I believe meth gives us a little so to me it is worth it.
Others turn it up more with meth and that's cool just I prefer to increase detonation safety. I use Blue windshield wiper fluid with one can of yellow 'Heet' that seems to make the gallon flammable. There is a big debate on the mixture as well
Thanks

Well it seems to be working pretty good. I only had the boost up to 12psi so far but one thing I notice is the IATs still rise but slower..and whenever I shift, they shoot down. then start to go back up again.
