Default Larger than 60lb injectors. Options?

What is available that is larger than the 60lb injectors by Motron but are not going to cause serious problems are need extras? I was told RC made 73lb injectors, but I have not been able to find them anywhere. I am thinking of going with a dual pump setup and maybe 73lb injectors and need help. I guess now, my goal is ~700 whp. Thanks in advance.

forgot to mention, this is via turbo, which from my understanding is more demanding on the fuel system.

The 60PPH rating on the Mototrons is calculated at a Fp of 43psi, 3 bar...
Have you calculated their flow rate, using the FP of your system???
My calcs show you need a 65PPH inj at 3 bar, at an estimated 775 FWHP, at 90% DC, .6 BSFC.
Running the Motos at 60PSI, base FP = 70.9PPH flow.
This should cover your FWHP, IF the FP reg is boost referenced. [BTW, the calcs on inj size are made using FWHP, not rwhp..]

HTH,
