Water/meth injection works, I would have blown-up or melted my motor years ago if it didnt. I test my system once a month with an ohm meter, air source and air pressure regulator. I also have an indicator lamp to let me know when the pump is operating. I have e85 local to me and I have thought of using it but I dont need it! I have ran up to 20psi. in my ford on 93 octane w/iron heads.

2 things I wont do again... buy race gas or build a high compression engine.

the National Advisory Committee for Aeronautics, in studies aimed at increasing the power from aircraft piston engines, came to the following conclusion: “The data indicated that water was a very effective internal coolant, permitting large increases in engine power as limited by either knock or by cylinder temperatures.”

Engine power production, referred to as brake mean effective pressure (BMEP), is measured by taking the average effective pressure of the cylinders as they progress through intake, compression, ignition, and exhaust strokes. Added power comes as a result of greater pressure, but a higher temperature inside the cylinder accompanies greater pressure. These higher temperatures can lead to detonation, referred to as engine knock, or pre-ignition, both of which are cases where the fuel-air mixture burns in an undesirable manner and can be destructive to an engine. To combat knock and pre-ignition as power increases, a richer air-to-fuel ratio is normally required. If the addition of extra fuel doesn’t provide enough knock protection, then a higher-octane fuel, which is more resistant to knock and pre-ignition, may be used. However, once the knock limit of a higher-octane fuel is reached, can anything be done? This is where a water injection system presents an appealing option.

The issue may be that cooling the charge may not be enough vs the higher octane fuel.

NEW! C85™
If you’re committed to using E85 type fuels, C85 is by far your best choice. Conventional E85 fuels are notoriously inconsistent, requiring up to a two-jet swing in tuning from one batch of E85 to the next. By contrast, C85 is blended with a consistent proportion of ethanol and every other component in every drum. In addition to taking all the guesswork out of tuning, C85 makes up to 4% more power and torque than conventional E85. With higher quality pure components, C85 is superior to E85 in terms of cooling effect, resistance to detonation and even includes corrosion inhibitors to fight the issues presented by ethanol. C85 works well in drag racing, oval track, off road and virtually any other automotive application, in particular forced induction applications due to its lower vapor pressure. Tests of C85 indicate most applications will require richening up by 1 jet size, or 2-3% over current jetting. Note that for racers unwilling to invest in the new carb and expensive fuel system upgrade required for E85, VP’s MS109, VP113 and Q16 continue to be the best race gas alternatives for the money.

Michael Plummer is a Snow Performance distributor. This is from his FAQ section (I've known Mike a long time from a Mustang site I've been a member of for 15 years)

3. Does the Snow Performance system work a carbureted application?
Yes.

We have systems for carbureted vehicles without superchargers or turbochargers. They inject according to vacuum and deliver 20-25 point octane gains over regular pump gas when using a 50/50 mix of water/methanol.
Any Snow Performance system can be used with or feature the special 4150 or 4500 style carb plates as well. MC and RT series systems include the carb plates.
Many muscle cars that previously required expensive high octane fuel now use regular pump gas with our system while getting better performance. These cars can use our MC (naturally aspirated) series systems for a clean installation and great results.

Thanks for all the discussion !!!
I "thought" that the Snow kit for NA had a fail safe built into it ?
It would not activate the controller if water/meth mix was low.
I meant to record his (Snow's) appearance on Horsepower.
In my case my CR is 14.58 -1. I am after cooler temps as well as a little more power and saving $$$ doesn't hurt. As hot as the center ports on our Pontiac's get the cooler the better..IMO. Can't hurt..
If I'm correct this stuff was originally used to give our WWII planes with super chargers a kick in the butt at higher altitudes to outperform our adversaries..without blowing them up..
I still think I'm going with the E85....but not a 100% sure..?

You'll be happy with E85 Troy,been running it for 3 years,no issues.My car sat for over 6 months this year,didn't drain the fuel,no issues.Gene also runs it and loves it!
