where do you guys locate the nozzle for your water/methanol injection? Before the IAT or after? Pics would be handy if you have em. I have one of those aluminum elbows already drilled with a nitrous port but was thinking of using it for meth injection however its before the iat sensor and I'm not sure that's a great thing.

 

I got two of them as shown and one right after the blower disccharge and I don't know if they have any effect on the IAT

 

Depends if you are using your IAT sensor to tune and if so, to what extent.

I prefer spraying post IAT because the readings a soaked IAT sensor gives are false data anyway.

But if you aren’t really using the IAT in your tune up and you spray pre IAT sensor… That is a good way to setup a safety in case the water/meth stops spraying. IE IF you see low IAT temps you know the water/meth is on. Anytime you see over “X” amount of IAT in boost you would cut ignition, pull boost/timing, whatever. Or add timing/boost only when the ECU sees those "false cool" IAT temps.

 

Thanks thats a great picture.
