Message I've opted into the group buy on the water injection kit. Before doing so, I had to do a little homework since I felt my situation was a tad unique. . .

I've wondered about the safety of the RaceLogic Traction Control system in my car. After my new motor is broken in, I plan on tinker with it to see how I like it. As many of you engineers and mechanics know (and a garage-amateur like me learned) it cuts a complete fuel pulse to one or more cylinders when it detects a predetermined amount of slippage. In this way, the "lean burn" threshhold is crossed since there isn't any fuel at all to fire so you don;t get detonation.

Water injection caused me to wonder, slippage occurs at high boost, when water is injected at its highest rate, so if you chop fuel for an injector cycle, will you wind up with too much atomized water in the system when the firing sequence resumes.

I polled a lot of people, Sebastian, Joe at Operation Z, Mark Leader, and The folks at Snow Performance and all agreed that the amount of water actually injected was too small to be a safety concern even if several pulses to the same cylinder were interrupted in a row.

Anyway, I plan on working with the setup to try it out, but I thought I'd just share my concerns and findings thus far from talking to people smarter than myself when it comes to the Z.
