Just remember 50/50 is max recommended. After 50% you start to lose cooling capacity.
I will be setting it to turn on sooner and probably switch to the .6mm nozzle this weekend.
I am at 82.6% fuel 17.4% water; the .6mm nozzle should bring it to 80/20.

will water injection leave a residue on ur maf sensor if u inject b4 it

No. That's where I inject. There's already water in the air you run through there every day anyway.

Is it true that water can have an ill-effect on teflon coated rotors?

willwren Feb 14, 2005 11:43 PM

No. Shoot the guy that told you so for sheer stupidity.

You got teflon on the frying pan, right? What happens to the teflon when you put water in the pan? It gets wet. Nothing more.

We like to think that 16000 rpm is fast, and it is for an Eaton blower, but it is too slow for there to be impingment damage to those big rotors.

A turbo, on the other hand, is much lighter construction and can spin at 100000+ rpm.
Even very fine water droplets will erode the compressor wheel.

Bingo. Which forces you to inject post turbo, which means you need a high pressure pump to get the water in there that the xxpsi of the air is trying to prevent.

With a SC, you can inject pre or post rotor (depending on what you're trying to do, and you're not having to overcome those high pressures. AND you still probably are flowing more CFM's than the Turbo you would have chosen.
