Default meth install

I'm installing my new meth kit... is it ok to mount the nozzle so that it sprays the intake air temp sensor and through the MAF? my only worry if i mount it after the MAF then the nozzle is only about 3-4 inches from the throttle blade.

You should install it AFTER the MAF. It doesn't matter how close it is to the TB blade as long as it doesn't hit it. Needs to be before the TB tho.

Anywhere after the MAF and before the T/B is where it's supposed to go. I hope the guy gets the message after all these posts.

To clarify for some of these guys, yes, it needs to be AFTER the MAF, and BEFORE the TB. As close to the TB as possible while still being able to fully anodize into the air going into the TB.

Mine is isntalled in my elbow in the pic, right before the IAT sensor. The methanol is corrosive, thats why you don't want it before the MAF, not to mention if sprayed prior to the MAF it would screw up your MAF readings entirely. Eventually the meth will corode away at the IAT sensor, but they are cheep to replace, and even if using 100% meth instead of the reccomended by Snow Performance 50/50 water methanol mix, it would still take years before you should need to replace a IAT sensor. Here's my Snow Performance setup. It is injected through the red line going into my metal 90 elbow prior to the TB.

Default Why not to mount in front of the MAF...

I have a junkyard MAF I'm going to gut eventually, since I run SD mode. For grins, I put my alky nozzle in front of the MAF. I'm injecting denatured alcohol and water, about a 70/30 mix.

Take a look at the yellow plot, it's the MAF output in Hz. When the alky flows, it causes it to read so high that it rolls back over to zero. Or, it's just plain freaking out. One interesting note, the MAF always seems to recover immediately after the alky stops flowing.
