type in "methanol injection" in google.
youll see more infomation than you can poke a stick at.

It lowers cylinder temps which helps prevent knock and I believe allows you to more easily mess with timing.

it makes the fuel a higher octane... for example not sure for a fact but im guessing using 93 pump gas it might bump you up to around 95,96,97,98 octane, and it helps with knocking

What’s this water/alcohol injection?
It’s a method for cooling the combustion chambers of engines by introducing water/alcohol mixture to the incoming fuel-air mixture. This allows for greater compression ratios and largely eliminating the problem of engine knocking due to detonation. Water/alcohol injection will effectively increases the octane rating of the fuel mixture, meaning that performance gains can be obtained when used in conjunction with a supercharger or turbocharger, altered spark ignition timing, and other modifications. Many water/alcohol injection systems use a mixture of water and alcohol (usually 50/50), partly because the alcohol is combustible, while water is not; in addition, the alcohol serves as an antifreeze for the water.
The system was first used extensively on World War II fighter aircraft to increase power upon takeoff and bring up the service ceiling. A limited number of road vehicles with large-displacement engines from manufacturers such as Chrysler have also included water injection. Saab offered water injection for the Saab 99 Turbo. GM had plans to put water injection on Turbo Regals. They have a "Power Injection" light on the dash and "Power Injection" location in the fuse box. Unfortunately it did not go into production. With the introduction of the intercooler the interest in water injection disappeared, but today, water injection is also of interest because it can potentially decrease nitrogen oxide (NOx) emissions in exhaust. Water injection is primarily used with piston-powered internal combustion engines, but it has also seen good results and use with turbines.
The initial injection of water cools the fuel-air mixture somewhat, which may allow for more mixture to enter the cylinder. But the greater effect comes later during combustion when the water takes in significant amounts of heat energy as it converts from liquid to gas (steam), increasing piston pressure (torque) and reducing the peak temperature with its resultant NOx formation as well as the amount of energy absorbed into the cylinder walls. The duration of combustion is said to be longer. An interesting side effect that has been reported by some is that water injection effectively "steam cleans" the engine interior, resulting in less carbon residue buildup. Glowing hot carbon deposits are a known cause of knocking.
Fuel economy can be improved with water injection, although the effect on most engines with no other modification, like leaning out the mixture, appears to be rather limited or even negligible in some cases.
Some degree of control over the water injection is important. It needs to be injected only when the engine is heavily loaded and the throttle is wide open; as with other systems which need to monitor engine load, this can be determined by manifold vacuum, which is low when the engine is loaded and high when it is unloaded; however, provision must be made for starting, when the manifold vacuum is also low but water injection is undesirable

I've flown an airplane that had meth injected engines. Basically a turbine engine is limited in it's maximum power by temperature. The meth would cool them considerably and allow more fuel to be injected without temperature problems.
