Really? there really aren't many gains to be had going from 93/meth to e85/meth. the meth is already giving you the octane and cooling boosts.... the e85 is just there as a safety precaution. I went to e60 and most of my gains were just had from the car leaning out from running out of fuel.

We dont have 93 octane where I live, can either get 91 or E85.

and you are running meth as a fuel source. if you are injecting meth... it's being used as a fuel. unless you are not compensating your injectors for it, and are running fat af.

I'm just getting into meth and will be installing the Alky kit along with E85 the end of this month. I'm trying to learn as much as possible about it so this possibly a stupid question but:
If meth increases octane then how can someone only use it for cooling purposes. It seems that if you inject an explosive chemical into the intake it's going to add to the fueling.

My stock engine was 705whp ,lt 4 fuel, 3.70 pulley meth n 93 @12lbs with just cat deletes ,it made it a year, Im thinking headers and 3" × pipe would have dropped boost enough to keep it under the tipping point. Plus I was stupid and never invested in HP tuners , I could have been logging and possibly caught it .

Agree with him, even a moderate amount of meth injection means that some fuel is being added. My thought is that if your intent is cooling more than fuel supply, then using windshield washer solvent like laynlo15 used to would be the way to go. The solvent is something like 35% methanol, so you'd be adding less fuel than you currently are with straight methanol.

I am not running straight meth, it is a 50/50 mix of M1 methanol and distilled water per the owner over at Alky Control. I have already logged the vehicle the current setup only changed the A/F ratio .01 which has already been corrected. To your comment of seeing any gains from 91/Meth to E40 with no meth. No, we didnt see any gains as that wasnt the goal of the project. The goal was to take the LT1 fuel system out, turn the meth injection off and not use it as a fuel source and to put the LT4 fuel system in the car and push the Ethanol up as high as I could and still make the same power as I did on 91/Meth. Project was a success. Car makes the same power and I didnt have to rely making sure the meth tank was full. The shop that did the original supercharger install said they didnt trust the LT4 stuff and meth inj was the only way, research from others like myself have shown they were wrong and that the LT4 stuff can handle 91/93 just fine and make around 600rwhp. Add some E85 and you can make over 600rwhp with no issues. I have the tune pretty conservative, at this time I am not looking to see how far I can go and lose a piston and end up with a $10k+ engine build as that is what will happen next. So yes, meth inj can be used and not be used as a fuel source. If you car is setup right with the proper fuel setup you can make up to 700rwhp without the need for meth only by using the LT4 fuel system and/or 3rd party pumps along with some E85.

As far as temperature is concerned, it is the same as putting rubbing alcohol on your skin - once it is spread on your skin it evaporates very fast, which in turn pulls heat with it, which is why it feels cool. The reason why you would use strait meth or meth/water depends on what you are trying to gain with the meth. For maximum cooling effect, meth/water will net more temp drop. Strait meth will supply the most octane. You would would want to asses your pre-meth situation on what you want to achieve - IE, if you are running boost but with no intercooler, you are pretty much going to be capped on boost about 5-7lbs. Add one meth nozzle and you can easily double that.
