water injection

[amalventano1@comcast.net (Allyn)]

Scott,
    You need high pressure for proper atomization in a water injection applicaion. Something like 30
pounds or so. That is for injecting right before the head. If you were to inject somewhere else
(i.e. before an intercooler for example), you could go with lower pressure since you need larger
droplets at that point in the air charge anyhow. I dont think that 'elsewhere' thing applies to your
situation though.
