The methanol injection idea is a good one and there are lots of kits out there. The water/methanol mixture (a myriad of windshield wiper fluid works, just not the kind with glycol in it) acts as as an intercooler through evaporation in the intake tract and is actually more efficient than an air/air IC. Water also acts as a detonation reducer, while the methanol acts as an octane improver so you get a triple whammy benefit of being less knock prone from the water, being less knock prone from the octane bump and getting a cooler intake charge from evaporation. The big downside is adding another consumable liquid and the weight of the fluid/tank to the mix on top of gasoline. Also, if going this route you need a good kit with a failsafe, as you are a clogged sprayer away from a melted motor...the failsafe controls the wastegate in case of failure to reduce boost pressure so you can drive the car home, albeit under reduced power.
