You can wire a retard system where, if the system fail-safes are triggered (for example if the fluid level in the tank runs low) then timing is pulled way back to prevent meltdown. These can be incorporated into a non-boosted app as well. There's pros and cons for sure guys, but it's not really correct to refer to meth injection as a band air or to say it does not raise octane rating of the fuel it's mixed with in the intake system, because it most certainly does.

No doubt that in a boosted application. the WM system can be a huge benefit. The basis of this discussion though is use in a naturally aspirated engine. I think thats where things can differ a bit. Every combination will respond different.

In your case, I think you are right; your mixture was probably not of benefit to your application and any benefit of reduced detonation was offset by the the fact that higher octane fuel burns slower and makes LESS power if you don't need it. You obviously know what you're doing, so I assume you tried to run more timing with the meth and it didn't matter. You were in competition and didn't have time to start experimenting with the mixture, you wanted to WIN. (Congrats by the way!) But we shouldn't discount the possibilities here. If you have a high compression N/A motor combo that needs 110 or 116 to be able to run aggressive timing advance, you could opt for a meth kit and properly setup it could cost less than race gas in the long run and be a lot more convenient. I think most guys haven't looked at this for an NA setup because the kits have been marketed to the blower/turbo crowd. Snow's 20020 kit is for N/A combos. And another guy mentioned AIS, I know Rodney, he sold me a kit several years back for one of my Mustangs. I had a Novi 2000 on a big-bore 347 and it was a very comprehensive kit. AIS also makes an NA kit with a pump in the tank. Not trying to cause trouble here, hope I'm not being seen that way. Just trying to add to the discussion is all..

No hurt feelings here. I'm sure that is some potential on a higher compression NA engine as well. I'm totally sold on the boosted applications!

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!
