Methanol blend
 
Hey, guys. I thought, 100%What is the merit of using methanol?I guess the cooling efficiency is higher for 50:50 and 70:30, but what? Because the moisture does not enter merit, it feels like a problem such as corrosion does not occur.I appreciate all the responses in advance.

I use 100% all the time.

I use 50/50 to 60/40, to reduce risk of fire.

What is the merit of 100% methanol? Does it improve output from 50:50?

i use 100%, no mixing. Using this mostly on recommendation from Trebila and his tune.

I see AIT drops at or below ambient

Higher Meth % would be required with higher boost and more advanced timing.

Presumably, you need to log and see if there are any knocks, if so, higher Meth % would be required.

Some run 100% because they need to (boost levels) and others do it at lower boost, just for the insurance factor.

I intend to start at 50/50 and log. Will go up to 100% or whatever is required to ensure 0.0 knock at 17 PSI. (this is simply my target)


Uneducated Comment: I believe water would have a better cooling impact, though Meth would certainly help too. I'll be testing this for myself soon enough.

I am using prometh direct port system (using 7th injector), but it seems that there is no problem at 22psi with a hybrid turbo at 50:50 blend so far so far.
Many people are using 100% methanol, so I was wondering what kind of change there is.

I did a lot of reading and the gist is that water is better for reducing cylinder temp (thus knock), meth is better for reducing intake air temp, and only methanol counts as fuel. If you need as much fuel as you can get, 100% meth is appropriate. Otherwise unnecessary IMO.

100% methanol has the effect of additional fuel? Thank you for teaching me. It seems that 50:50 is more advantageous for cooling effect and knocking prevention. I also try both logs.

100% methanol is twice the fuel vs. 50/50 meth/water. Makes sense right?

I think that it is more advantageous to run 100% methanol than you think from your opinion. You seem to have a wealth of knowledge and experience with methanol. So it will be helpful. It was troubled because it became difficult to set after making it a direct port system.

has anyone here broken a throttle body running 100% meth? I ran maybe 5-7 gallons of 100% VP M1 before my throttle body was cooked. I am injecting through the chargepipe.

I have been running meth for over a year at 50:50, but the throttle body has not broken down. Is not it a coincidence that 100% methanol seems to have no adverse effect on the throttle body?

There is no way methanol can ruin, brake a tb
