Welcome to the WI forum. 
 
You propabably need more fuel then your stock injector can supply. Running 8-10psi will get you more than 20-30bhp. Additional fuel can be supplied by additional injector driven by a piggyback ECU. 
 
WIA can be use to keeping things cold and suppress the onset of knock. But I doubt if you can get away with adding alcohol to suppliment extra fuel requirement for 8-10psi.  
 
50/50 will help you running 8-10psi.  Your effective compression ratio will be around 12:1
