I think you ment to say lets you run more timing. By raising the octane level it is the same as running race gas. You are able to run more timing if you have the means to adjust it. And if not you will just see your full timing because you will not have any Knock. If you have a IAT sensor and either spoof it with a 4.7k ohm resistor or spray your methanol before the sensor you will have better results because the computer will see the temperature drop as well.

On my GTP I ran 26 degrees timing at WOT with a 20/80 mix and a M10 nozzle, Off the alcohol i could only run 15 degrees with the 2.8 pulley. I had no cam and no intercooler and was still running 13.00's. Every degree of timing is around 3 wheel hp gained. So it makes a noticble difference.
