[Diy_efi] Re: water injection

[Bill Washington]

I ran a 2litre, naturally aspirated, carburated engine with with water 
injection for over 200000Km (~1982- ~1995).
I didn't notice any power change, fuel economy may have improved 
slightly - ~9litres/100km normal consumption achieved - it was a Peugeot 
504 station waggon, so it was a sizable body for the engine.
I had to rebuild the engine at about 400000Km due to head corrosion (- a 
repair shop had not put inhibiter in the coolant, resulting in a blown 
head gasket!)
When I pulled the head off the chambers and pistons were very clean! no 
carbon build up at all - so I concluded that if all the water did was to 
keep the combustion chambers clean - it was worth while! - they work a 
lot better without build up of any deposits!
