The Problem with a superchargerkit, without intercooling, is the hot air which is terrible for the engine and kills all boosts-gains becouse the engine is pinging and the ecu retards the ignition ...
Methanol pulls heat out of the charged air when it quickly evaporates from the atomization. That, in addition to the h20 saturation slows down the fuel burn, allowing for significant amounts of increased timing, which lowers EGT, allowing for a leaner AFR and more boost before detonation occurs and the EGT comfort zone is exceeded.

So yes, it REALLY allows for more HP. It doesn't produce it alone, but allows for significant alterations to a tune which will make more power.
