I can partly agree.

I can see hydrolocking being a issue but I think that Would take a lot of flow to do that. But not no where neir melting the engine.
i believe he means if you tune to HAVE to use water to cool the engine then when you run out of water or flow stops for whatever reason you are in a bad place engine health wise
 
what engine? idi ? di? and are these newer engines with newer technology/ metallurgy piston design etc?
mine is an old tractor engine 3b-t....
i know that di can take more heat, and have heard people say their 1hdt xxx will take 1350-1400 (or more for short stints) without issue
I feel safe at 1150 continuously, 12-1250 for short pulls but start to worry about pre-cup, piston and head health much after that
some people seem to get all scared about 20 psi, but i feel the heat is the bad factor that needs to be mitigated

i appreciate the opinions offered from everyone
With my setup 1HDT 1250F it takes quite abit to get up there. I’m sure I can get it past if I increase the fuel and dial down the boost.

Mine, 4BD1T and VAG BMM tdi. Both direct injection, both with oil squirters under the pistons.

1200F (650C) sustained is perfectly safe for you.
 
What are the implications of running out of water/methanol mixture?

The impact largely depends on your current tuning settings and how you utilize the system.
For instance, if your current tune is mild and your truck runs well with acceptable Exhaust Gas Temperatures (EGTs), some argue that water/methanol may not be necessary.

However, many still choose to use it due to its proven benefits, such as reducing EGTs, improving fuel economy, cleaning properties, and enhancing overall efficiency and power.

If you run out of water/methanol mixture, you have a few options. You could drive to the nearest service station and use washer fluid as a substitute, or go to a hardware store to purchase methanol/methyl hydrate and distilled water to mix your own on the spot. Alternatively, you can simply turn off the system and drive carefully without it.

On the other hand, if you're running a high-performance tune that heavily relies on water/methanol, it's advisable to carry extra mixture with you and refill when necessary, or consider using a larger tank to ensure an uninterrupted supply.

Reducing EGT isn't a benefit. If your tune is safe then lowering EGT will reduce efficiency and performance. If your tune is unsafe then it needs fixed.
It is EGT that feeds your turbine.
The fuel economy and efficiency claims are simply displacing diesel with methanol.
 
So why is glycol bad for running water-methanol when using different washer fluid types???

alot of people run the rainX brand which has higer glycol percentages

in Canada, we can get winter washer fluid down to -49C pretty affordably $13cad for around 9L

MSDS: says it contains around 30-60% methanol and > 1-5% Ethylene glycol

could mix my own by weight pure methanol and distilled water price about the same.

and easily available at home depot. 99.9% methanol

MSDS

your engine aint meant to burn glycol
methyl hydrate and distilled water have little to no residues after combustion

Thanks. I’ll probably just be mixing my own. I just haven’t heard of any side effects of using washer fluid. Besides washer fluid not being as
Much as a strong mix.

Glycol probably gonna clog up stuff because of the residue.
