I thought this topic jogged  a spot in my memory..GM had water 
injection in 1962.  Below is a description I found on the web.

All '62 Cutlasses offered a 185-bhp "Power-Pack" V-8, but greater 
interest surrounded another new derivation. This was the turbocharged 
Jetfire hardtop coupe, which shared honors with Chevy's 1962 Corvair 
Monza Spyder as America's first high-volume turbocar. With blower, 
the Jetfire V-8 churned out a healthy 215 bhp -- the long-hallowed "1 
hp per cu. in." ideal -- but carbon buildup with certain grades of 
fuel necessitated an unusual water-injection system (actually, a 
water/alcohol mix).

While the Jetfire was remarkably fast (0-60 mph in about 8.5 seconds, 
top speed around 107 mph), the water-injection proved unreliable. As 
a result, Olds abandoned turbos for 1964 in favor of a conventional 
330-cid V-8 of 230-290 bhp; at the same time, Buick's new 155-bhp 
225-cid V-6 became base power for the F-85 line.


My 65 Corvair Corsair Turbo had 180HP for 164cu and would squeal the 
tires up through 3rd. Good car except no one could work on it.  I 
took it in for a problem under warranty and when I picked it up, they 
said the vacuum advance had to be replaced. I said it had none, 
rather a pressure retard. They said they were sure they had replaced 
it correctly and after a spin around the block, I went back in and 
asked them to check to part they used versus the  part the manual 
called for. I  also said I doubted they had a pressure retard in 
stock.  I was right on both counts.
