Guys with water/alky injection Where did you mount your nozzle? I have a c5 with the ATI kit. I’m planning on mounting it in the air bridge between the MAF and the TB, but I was not sure if I should be closer to the MAF or closer to the TB. I’m a little concerned about screwing up the MAF readings, but want as much atomization as possible.
BTW, the ATI is a push setup, not a pull.

Re: Guys with water/alky injection I talked to steve at SCM and Iam going with a dual nozzle setup. Iam getting a larger #5 nozzle b4 the intercooler and a second #3 nozzle after the intercooler which will be mounted in the intake bridge b/w the MAF and TB.
Whatever I spray b4 the intercooler will probably be completely gone b4 it reaches the MAF. Any vapor will probably get trapped inside the intercooler and the air rushing though it will be cooled even greater due to the larger surface area within the intercooler. So Iam hoping that the only thing reaching the MAF will be colder air.
I plan to keep the second nozzle closer to the MAF to allow more atomization b4 whatever you spray gets into the engine. I could be wrong on this?

Re: Guys with water/alky injection Im going to mount mine right in front of the throttle body just like if it were a n20 setup. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: Guys with water/alky injection I like the idea of a nozzle before the intercooler, but it seems like that moisture would have to go somewhere. I gues it does not matter if it is pure alky and it is completely evaporated into the air.
I don’t completely understand how the MAF works. I know it somehow measures based on the current required to maintain a constant temp on the elements. It seems like any moisture on those elements would really throw things off. The alky might also damage them.
Maybe someone can chime in with a better explanation of how the MAF works. I just don’t want to screw up those readings.

The big benefit of alcohol is that it absorbs heat when it is transformed from a liquid to a gas. If you are spraying it before the intercooler, there is much less heat to absorb than in the combustion chamber.

Re: Guys with water/alky injection Inside the intercooler there is allot of surface area that the moisture of the alcohol will adhere to. And with the hot compressed air blowing through, it should completely evaporate b4 it reaches the MAF.
The reason I want to do this is that I want to drop the airtemp of the intake charge b4 it gets to my MAFT. So when the MAFT reads it it will log a cooler number and increase my timing.
