I ordered some Bosch 63lbs @43.5 psi injectors for my whipple build. Texas speed said they have made 710 whp on a LS3 Camaro with these injectors. I have a 6.2L LS3 with a whipple 2.3l and I am going to push around 12 psi boost to it. Are these injectors enough??? They said they can flow far more then the 63# spec because that was rated at 43.5psi and running at the GM 58psi fuel system rating Should be closer to 70-80lbs.
If you are running a solid 58psi of fuel pressure they would be 72.7lb/hr injectors.
This is a rough calculation here but if you were to run those injectors on pump gas to about 90% duty cycle they COULD support like 850-875 crank horsepower. You can easily google a few different injector calculators and they will give you somewhere in that neighborhood of horsepower.
850cc are loser to 80#. Are you running pump gas? At 12# you may end up near the top of the duty cycle of those injectors. But not max them out. If you decided to go to e85 then they most certainly would be maxed out.
