need a difinitive ans: on a turbocharged/superch. engine, all things being unchanged, will hot, wet air sustain less boost than cool/dry air? in other words will my boost (87 gn) be somewhat less in summer (95 deg.), than in fall (50 deg.) i am showing about 19# even after shortening my waste gate rod. ------------have alch. inj. knock will eat me up if is not used. i know that the alch. spray cools the egt. and a little boost will be lost but i would like to be able to run about 20/21# if possible. any help....appreciated
