<< The formula for calculating the injector size is as follows.
 pounds of fuel per hour is equal to the expected bhp times 0.55 divided by
 number of injectors, then divide by 0.80. ( you want injectors at 80% max at
 peak power)
 
 400 hp times 0.55 = 220 divided by 8 = 27.5 divided by 0.8 = 34.375 lb
 injectors.

Don't forget to factor fuel PSI...
