Nozzle Installation Questions

Dust · 09-10-2008

Is the pump supposed to pulse and the nozzle supposed to drip? I hooked up the nozzle, and the pump was kicking on and off, and the nozzle was still spraying after the pump turned off. Is this normal?

Any comments on mounting the nozzle in the air box? I could aim it at the intake pipe, and that way any drips that come from the check valve will simply fall on the air filter, and evaporate. There is only about 2-3 inhes of space from the top of the box to the filter, but that is honestly more that the piping and the water is sprayed at the opposite wall instead of into the pipe. Any good or bad comments?

No drips should be coming from your chk valve. Trim the end of the hose a bit and try re-inserting it.

I know people have been doing it, but spraying pre turbo has been proven to wear your turbo blades over time.

I know they say w/ the high pressure nozzles the water is so atomized it won't hurt your turbo. It will just wear your turbo slower... but it will still wear. There will always be puddling when you spray fluid into a pipe. And the water droplets will errode your turbo blades over time.

Do what you will, but I've beat up a turbo pretty good spraying pre turbo.

Also it alcohol will puddle in the IC, and if you have any kind of backfire through your intake the meth will ignite and at the least probably blow your pipes apart. (if your running straight meth.) And if you run a 50/50 mix it will still corrode when the meth touches the alum. housing on the turbo and your IC.

Either way not a good idea if U ask me.

I personally have run as high at 30psi on pump gas and alcohol with little to no detonation.(low timing). I found 25psi and 25* of timing seems to be the sweet spot on my car. I don't see why you all think pre turbo is necessary?

Not many turbo's are effecient over 25psi anyway.... So if you can reach the max effenciency of your turbo without it, why rot out all your alum parts and destroy your turbo?

The dripping I was referring to was the water coming out of the nozzle after the system shut off. the system going from 2xx psi to the 2x psi of the check valve.
