Power, please. Recognize need for anti-freeze in cool temps.
Plenty of data. Most of the data is drag strip and track speeds.

The fastest guys here run 100% meth.

Water injection doesn't work nearly as well in most applications as meth/water. Water isnt combustible and takes up space that could be used for air and fuel. But it absorbs lots of heat when it vaporizes which cool things very well. So its a tradeoff.

With meth or meth/water, there is very little tradeoff since meth is also a good cooling agent while being combustible. And on top of that, it has high octane. Pluses in all areas.

Simple at home science project. Dip one hand in water and the other in rubbing alcohol, blow on both.....which feels colder?

Im running rev 2.5,dci,kittyless dp, and pwm kit. Car feels smoother ad even sounds "healthier", dont know if its in my head but it does sound like the engine is running happier. Power can only be described as brutal but in a smooth way if that makes any sense.

When the engine revs at the higher rpms 4000-6000+ it just sounds and runs more smoothly than without meth...Car is also noticeably faster without a doubt

Just my cup of tea.

Modulatability? Not a fan of on/off - prefer total, silky control from start to max.

Ungh meth has me so intrigued but its another thing to un-install and re-install for service. Plus i would have to order meth, since there's no place to fill a drum around here.

but for the gains. and i heard your engine runs cleaner
