the proper calculation for injector size is:
cc/min = lb/hr x 10.5
lb/hr = expected bhp x 0.55/ number of injectors
(the 0.55 figure is actually the maximum load brake specific fuel consumption of a typical turbocharged engine)
so for instance:
300bhp x 0.55 = 165
165/4 = 41.25 lb/hr
to get the injector size in cc:
41.25 x 10.5 = 433.125 cc
440cc injectors should be sufficient but it's good practice to choose the next size up for future improvements.
