So the methanol maybe detrimental to the rotors but must be used for proper evaporation to prevent pooling and damage. Maybe I can ask BillBoost37 to pour WW fluid on his leftover rotors to test for damage.

I have 100% methanol here. And a couple test SC'*.

Wow. You went 100% methanol with no damage? How long have you been doing that Bill?

Remeber that his rotors are not coated.

Mortehl, I said I HAVE 100% methanol. And a couple of TEST SC'*. How do you think I mix my 50/50 mix?

What I'm saying is that I'll test the rotors with 100% methanol to SEE what it does. And to clarify, I have TWO cars. One without and one with epoxy coated rotors.

I also have TWO spares. One for each car.

Of all the M45'* Neuspeed has seen with coating damage only two may have been related to water injection. Most of the VW'* with M45'* are injecting pre-rotor, including Neuspeed on their 2000 test bed.

I would not be too concerned about coating damage.

Rotor coating damage should not be a problem. The fluid will improve the rotor seal and may produce a pound or two of additional boost pressure.
The correct flow rate for my application will be 375 ml/min.
That'* about the same volume as a can of pop every minute at full flow.
The trick is full atomization with a fine mist, so the nozzle design and pressure is critical.

I've found that pressure is not critical with the right nozzle.

My Aquamist nozzle provides full atomization at anything between 10 and 70 psi.

Pressure is related to flow.
How much flow do you think it is capable of and how do you know it is enough to take full advantage of the benefits :?:

The flow at 10psi is within 90% of the flow at 70psi. I know because I measured it. I don't recall what the flow numbers were. I was looking for consistency.

I'm using pressurized air to deliver rather than a centifugal (expensive) pump. This is my 3rd system using this method, and it works good.

Especially considering I have air on board.
