do i need bigger injectors? Ok so im putting an ERL built 434ci ls into my g8. Its an 11.5:1 motor that should make right around 625-665hp im hoping. Wandering if the stock injectors from the g8 have a prayer of hanging in there? or do i need to upgrade if so to what? i know they are only 39# stock injectors but they are rated at like 40psi and the fuel system runs at 60psi. In z06's i think they get people out to about 550whp which is about where i think ill be at the crank, your opinons?

For power in the 600's, I'd suggest at least a 42# injector, maybe even a 50# if you want some room to grow. You'll need around 42-44# for fuel for the upper range of your power goals. 42# injector @ 60psi will give you just under 50# static, and that should keep your IDCs in the mid-lower 80% range.
