People have been doing this in race cars for years if not decades.
Windshield fluid is like 70% methanol or something like that. Its an easy way to decrease combustion temps and allow for more advanced timing (in a gasoline car) without running into denotation issues.
Not sure how it translates to a diesel since a diesel operates on denootation basically. I guess if the combustion chambers got too hot, it would denotate way before the piston got close to TDC, and this would be a good way of remeding that.
Either way, the major downfall is you have to keep refilling the system. Honestly, unless your looking for every last HP , your better off with just a properly tuned engine without it.
drag racing - sure
Dyno queens - sure
Real life, not really the all that sensible.
