Advantages of higher PSI for Water Injection?

Forrest Nearing said:
yes, a lot of the home-built systems we made back in the day were plumbed like this because the pumps we were using were pretty weak. Granted, this was on cars making 15-25psi, but pressurizing the front end of the resovoir took that differential out of the equation.

it definately works! :D

Thanks Forrest! Glad to hear someone has done it before but you do make a good point, it kinda does sound like a bandaid for the weaker pumps. I've seen people run a boost line to a sealed resevior before but that was on a gasser and he was actually injecting it with only that boost reference as the means of pressurising the fluid and he was injecting it into the low pressure side of the turbo (ie. the inlet of the compressor). Keep in mind he was only running 9lbs of boost, but i actually worked, until the water started to degrade the compressor blades of the turbo. It was on an old chrysler 2.2 non intercooled setup. Yes very ghetto but actually pretty quick for his budget. running in the high 13's in a lebaron - very unsuspecting :ft:
 
What if you used an outside source like a compressed air tank? Fill to 120psi then regulate to say 10 psi under your max boost. Use aulminum tanks the same size as the resivoir, mount in front of the bumper, call it part of your weight bracket.
 
Anymore and I'm thinking that the best course of action would be a 120 volt pressure washer and a big power inverter.

I just need a bit of venture capital. Nitrous solenoids would be the most expensive part, washers and inverters are cheap off of ebay.
 
Why not run the pump from one of those 120v washers with a 12v motor instead?
 
It wouldn't be hard to use the pressure washer pump and a starter motor. The hard part would be guesstimating how much of a starter motor you'll need for the pump. Then just getting the shafts to mount.

The big reason that keeps me from contemplating that route is the fact that I want to mount the pressure washer in my toolbox; if I had a starter motor in my tool box, I'd need to wire it with like 25' of 00 wire... If I had a big inverter right by my battery in my engine compartment, I'd just have to run an extension cord to the tool box.

If there's room in the engine compartment somewhere for the unit, 12 volts would be king. I don't know how well your run-of-the-mill cheapy inverters deal with motors like is on a pump? Is the AC wave clean enough for that?

It'd be cool to have a 2000 watt inverter for other utility reasons too.
