Default Spray before or after the MAF?????????

I have a ZEX wet kit and have heard mixed reviews about where to put the nozzle. I want to spray AFTER the MAF but I still have the stock "accordion-like" bellows. My buddy sprays right in the side of his lid before the MAF and hasn't had any problems with the sensors, not sure about it but he also said when you spray in the lid the fuel-n20 mix atomizes a little better, basically what i'm saying is that will I hurt the MAF or IAT sensor if I spray before them?

Does it matter that it will be so close to the TB. Many people (including vendors) say to keep it about 6" from the TB

Go to Home Depot and replace the accordian with a 3" Fernco, yes it will be a tight fit over the TB but once there your good. Wet = post MAF, Dry = Pre MAF.

Definitely spray it after the MAF. The MAF was never meant to flow fuel through it. Look into picking up a smooth bellow. You could always run a fernco coupler as a smooth bellow.

The nozzle should be OK then closer to the TB mounted into the fernco piece w/o any problems? (after all itll be tapped into a piece of rubber)

IF the fernco is tight when trying to put it on, pop it in the microwave for 15-60 seconds and it will go on like butta.

As for mounting the nozle in the fernco, depending on yoru nozzle you probably could use a combination of washers and nuts to make a nice mounting that is secure on both sides of the fernco.

How close is your nitrous line to the PS Pump pulley? From your oic it looks CLOSE! I am sure it's not, but in that shot it looks like it's resting on it. Also is your fuel line going to the fuel solenoid hooked up in that shot?
Just wondering...
