MW50 -Secondary effects were cooling of the engine .

[Mustang]

A different system boost known as MW 50 was also used, although GM-1 and MW 50 .....
However, MW-50 was not a nitrous-oxide system, ...
but a Methanol-water injection system, which injected a mixture of methanol and water into the cylinders to cool the mix. Cooling causes the air to become denser, therefore allowing more into each cylinder for a given volume. This is the same principle that intercoolers work on.

I encounter new data in everywhere.
So easy..
All aim to the same point.
