just read a brief article on the Aquamist water injection system. Anyone have a list of the pros and cons of such a system on a 3rd gen? Is it really as effective as people make it out to be?
thanks,
kevin.

I dont know how effective it is but since installing water/alcohol injection on my FD I was able to find a small leak at the trottle body/intake elbow O-ring thanks to a small amount of water bubbling up. I cant tell any difference in power but I mainly did it as a preventative measure.
Pros and cons would be exactly the same for the FD as any other car. The Grand National guys swear by water injection and have been doing it forever. Here is another page about water injection and there are instructions on this page to build pretty much the setup I have.

Yes, water injection works quite well at raising the detonation resisitance of your engine.
I won't go into all the details here but basically it makes you engine behave as if it's running on much higher octane gas. You won't really get much more power if you keep your boost levels the same. But you can safely increase your boost levels with less risk of detonation and in turn get more power.
The water also has cooling effects which helps power a little bit.
Make sure you add a little alchohol to the mix to prevent corrosion.
The downside is that if your water injection system fails or your water tank runs dry you will have engine damage. With a rotary you will almost certainly have total engine failure. In my experience most water injection systems tend not to be super reliable.
