Water Injection

[jgarrett]

So i got my parts list for my propane system and will be workin on it in the next few weeks. Now may attention has shifted to H2O/Meth injection. Does anybody have any advise on a diy system. * what size nozzle do most people use * im lookin at a 100-120psi pump.......is this enough can you run propane and water injection.........if not which is better.

If you use propane then do not add the methanol, just use water.

Pressure depends on your boost. The higher your boost the higher the water pressure has to be to get the flow you need.

ill just have my stock turbo so max about 40psi

also im lookin at pressure switches and a found some oilpressure switches here locally that are set at 5psi at napa..........are oil switches normally open (NO) or closed (NC). i need a NO switch.

is 5psi what i should be lookin to activate both systems

also i found some nozzles for the water @ www.mcmaster.com part # 32215k12

these nozzles have a built-in check valve that close when pressure drops below 70psi so no dips of water or anything

any comments or suggestions

I don't know at what pressure you would inject propane but 5psi is way to low to start injecting water. Minimum is 20-25psi from all my investigating.
