Does anyone on here do it? I'm thinking of running it on my car. Any reviews?

Meth meth/water would also increase compression ratio and cool exhaust temps.

It'll give you a little bit of power from the meth(dont expect much) and on a poor or no ic setup will lower charge temps, I have tmic and it reduces charge temp from 70 to 40deg iirc(celsius). The water reduces egt a small amount and lets you run a little more fuel.

The primary benefit is to keep the engine carbon-free for maximum lifespan and efficiency. Cooler intake air and additional fuel are just a bonus.

The other side of that is its far more important than ever that the oil be frequently brought up to operating temperature to boil off the increased moisture contamination. Coolant temperature does not correlate to oil temp.
