The meth is used to cool the air, it does raise the octane but you're spraying so little its negligible.I did my thesis on methanol injection but here is the crux of it... using a time frame of 2 revs at an engine speed of 5,000rpm, injecting a know quantity of water:methanol at a mix of 50:50 the energy required for vaporisation of the mixture is 139J. This after another page of calc's using the data of mass of air from the MAF it results in a charge temperature drop of 23.63*C. This increase engine hp from 293bhp to 325bhp. This increase is not ONLY down to the denser air though, the ecu also advances the ignition to take advantage of the cooler air, so some of the power increase has come from increased ignition advance... This only works if your mix is fully vaporized before it hits the IAT sensor. If its not it will wet the sensor and it will record a much lower temp, advance the timing too much and ping its little pistons out !!!huh.... the majority of 6 months work in a few lines !!!</blockquote>
