I'll chime in here only because I am interested in the topic and have been 
running a WI system in my car for about a
year with good results.

My car isn't a turbo, it's a 110 PG and I have a single nozzle with an "M2" flow 
rating spraying from the center of the air intake
tube that joins the carb throats.

I found that even a smaller nozzle on each end of the tube was too much water, 
the engine stumbled too much at idle.  The center mounting
seems to give a good balance and the car doesn't ping with timing advanced to 
around 16 btdc.

A temp control unit prevents the unit from operating until the engine is warmed 
up.  A vacuum switch prevents operation unless the car is in 

acceleration mode.  I use 93 octane gas and all flat spots and hestiation are 
gone.  Idle is nice and smooth.

On an unrelated note, my thermostat crapped out again, but the Clark's fuel pump 
seems to be doing its job without leaking and stinking up the 

interior with raw gas smells...Bill Hershkowitz 69 Monza Coupe 110 PG A/C no
