are 30lb injectors enought? i have a 402 with 225cnc TFS heads and 11.1 compression and a 600 lift 242 250 cam..i will be spraying it with a wet kit 150 shot..are 30lb injectors big enough?
30 lb/hr @ 3 bar are not enough for a stout 402. You need to invest in some 42 lb/hr @ 3 bar injectors or similar size. Check out FICINJECTORS (sponsor), they have some great prices on the Bosch Design III's. They are easy to tune, more efficient, and have better atomization characteristics than the Bosch Design II's.
I agree, I would say 36# minimal and 42# would be perfect. For example, I have 36# on my MS3 setup and it will squeek by but if I do anything else, I will have to get bigger. Less than 80% duty cycle is what your looking for. 42 should do it so +1 to 405HP Z06
I'm no expert though just my .02

Ultimately, power output and BSFC will dictate injector size so I'm making an educated guess on your combination. Here is the calculation based on 600 HP and a BSFC of .46. This combo would need 36 lb/hr @ 3 bar injectors to stay at or below 85% duty cycle.
