[Diy_efi] water injection

[David Allen]

One I've seen uses a Vickers Vane hydraulic pump, which was the original 
steering pump on the engine.  The man I talked to mixes his water with 
soluble oil (as used for machinist's tool cooling) to protect the pump; and 
injects at over 1000 PSI through nozzles like used on a pressure-washer. 
Injection is per-cylinder at the intake ports,  plus one nozzle just after 
the last turbo at the inlet of the intake manifold. There is a lot of water, 
but I'm not sure the exact volume.
