The F1 boys used water injection on both turbo and non turbo in the mid
'80's until the water was considered part of the fuel capacity of the car.
They only had 150 liters of fuel to play with.  Ferrari in association with
AGIP used a deal called 'Emulsistem' which emulsified the fuel and water and
squirted it through the injector.

Both BMW and Ferrari abandoned water injection in favor of high percentage
toulene based fuels.  Although most teams used water sprayed intercoolers
until boost was limited to 2.5 bar absolute.

The non-turbo teams used the water for the engine and to cool the brakes.
They would also add water along with tires midway through the race. Funny
thing was when the water reservoir was inspected after the race it contained
water and lead shot!  They were starting the race under weight and then
adding ballast during the pit stop for the last half of the race.
