cheers lad, i shud b ok so i be pusing bout 320isn only

555 divide by 5=which is 111
111 multiply 4=444hp at 100% injector duty
444hp taking the max you should run a injector safely is 80%
thats 80% of 444 is 355.20hp

so bart is on the money,around 350ish

what happens when you decide to get a bigger turbo???i am sure i saw 740cc injectors on here for around 350.your turbo will take what ever size injectors you fit once the car is mapped properly

its all a formula lad
