[s-cars] water injection

[Joe Pizzimenti]

I think this is another case of the "theorists" on list worrying about
a possibility that will never happen.  I've been running
water/methanol injection for a while, running basically a closed
wastegate (as much boost as the turbo will put out) and had a few
times where I've seen steam come out the back of my car and haven't
had a problem yet.

I've never heard of impeller blades exploding because someone got a
little happy with the water.  Someone care to prove me wrong?
