if you were to spray the dry kit at your estimated 475hp level it would take at least #33 pound injectors (thats at the maximum 90% duty cycle). the closest available size is 36# so you should go that route.

it takes .5lbs per hour to make 1hp.
take your hp level and devide by 2, than devide by the number of injectors (8). this will tell you fuel needed at 100% duty cycle, 90% is the highest you can run without damaging the injectors over time. add 10% for your final number

475/2= 237.5 /8 = 29.68 + 10% (3#) = 32.68# dry kit

325/2= 162.5 /8= 20.31 + 10% = 22# wet kit

Well they only inject as much as you need, so if you got 30#'ers when you only needed 24's, no harm done, plus you woudn't be relpacing them if you decided to add boost later on.
actually thats not true... if theinjectors have such a small pulse width bcuz the injector is too large then ull have driablility issues

however with the setup you running i think ull be ok with 30s... only if u have bigger plans tho
