Default Question about 1000cc injectors?

How much WHP can 1000cc injectors support on a fully built b18c, 9:1 C/R with a T3/T67?

Im thinking bout re tuning and wondering if I should get bigger injectors. Im making 425whp @ 15psi currently. I want 600WHP

u have a t3/t67 and u only pushed it to 15psi?

u can make upwards of 700whp with a good fuel system, the most i would push it with a walbro would be like 600whp, but if u had a good system that can support higher pressure max that turbo out

well I have never driven a car this powerful b4 so I am now getting familiar with how this car behaves. 15psi on this thing is scary...lol. well at least for me...lol. I have Aeromotive A1000 fuel pump, all steel braided lines, holley fpr, STR fuel rail and venom 1000cc so i guess that should be okay for 600whp.

I also wanna hook up some sort of direct port water/alcohol injection.

610whp: Fuel system consisted of 255lph intank, RC 1000cc injectors(peak & hold). Everything else that had to do with the fuel system was factory.

He means turn up the fuel pressure. If you're only pushing 30psi at the rail you'll get a lot less fuel than at 50psi. Or maybe you're asking the rail to flow too much, just another thought.

Maybe you're running out of flow through the rail then.
