So I'm in the process of upgrading my engine and I was running some numbers that say that the stock injectors run about 250cc and with the HP numbers im shooting for I will need 500-550cc ones. My question is how accurate this calculator is for injector size and if I will need a better fuel pump. Also Im about done with the first part of the build and should be making 330ish hp at the crank, are the stock injectors still safe at this point?
