You quoted:

"For best results, I recommend injecting it right before the throttle body. This ensures that you get the full benefit of in-cylinder cooling."

Are you sure about that? I just checked the aquamist web site and it said:

"13. Where do I place the water jet?
Normally immediately after the intercooler unless the intercooler suffers from heat soaking such as the type that is fitted on top of the engine (Subaru, GTI-R, Toyota Celica and etc). "

I found this picture with the injector right into the Y pipe before the intercooler:

I know Jackson Racing provides W/I solution for supercharged Miata's. How do these systems compare? or are they all using the same pump, nozzle, etc.?

DavidV, thanks for the reply and pictures. I'm a believer of water injection!

It just seems so wierd to spray into the intercooler. I would think the water would puddle and have a difficult time getting to the throttle body.

It uses high pressure pump and a special nozzle to pretty much vaporize the water going into the intake. that is what makes these so special.


DavidV,
couple of questions.. the pump used in the pic looks very similar to JR kit. Have you seen the kit from JR? Are they the same?
Any side effect from using longer waterline from pump to nozzle (vs short)?

Thanks!

I forgot one... any interference due to the type of pump used? Do you need to install away from certain electrical parts?

What are we talking about, water injection or intercooler sparying. I think you should clear up water injection and intercooler spraying. JDM STI's have i/c sprayers not water injection. Water injection is when you spray water into the combustion chamber to lower egt's, not spray at i/c to get lower intake temps.
We are talking about water injection - the debate is should the injectors be before or after the intercooler. IMHO they should be before the intercooler.
