Hey all,
As you know, Zak runs water injection and I'm planning to very soon as well. Zak and I have talked about pre-turbo injection, as Richard L (the engineer behind Aquamist systems) recommends often that we put the injection as early as possible in the intake tract. Zak and I both agreed after some talking that pre-turbo injecting would probably not be very good (I at first thought it would be, but wasn't willing to sacrafice my new turbo to try it). Well, after a year and a half of doing pre-turbo injecting, here is what a guys turbo looked like:
I had actually talked to Richard about pre-turbo injecting and he is actually coming up with a nice injector to do it... I probably won't be doingit now though!

Good choice putting $4,000 rims on your 1990 Honda Civic. That's like Betty White going out and getting her tits done.

I bet if you are running in competitions and such, replacing the center section of a turbo every month or so is no biggie, but not quite where we are at, I don't believe. If we are trying to squeek every las bit of torque and HP yout of our blocks to use this, we need serios help!
Patience is the ability to idle your motor when you feel like stripping your gears

There is a huge amout of chatter on this very issue on just about every WI forum board. The fact is that the water mist has to be very fine otherwise the droplets will pit the blades when impacting them at supersonic speeds. Some claim that such "pitting" is unlikely and is hard to prove. I have never seen a compressor blade that is that badly damaged, I'm almost tempted to say that some other particulate matter may have entered the air stream to do that kind of damage. I knew a Porsche turbo guy years back that did a pre turbo WI and made similar comments though I never saw any visual proof. He eventually moved the nozzle to post turbo.
