Injectors are coming too this year - from SEMA
I don't know if the DI pump will flow enough for E85 and high HP but for a big turbo pump gas engine it will definitely help. The key is the mid RPM drop in pressure due to low RPM and high torque/fuel requirements.

That makes me wonder, though. . . we know the stock fuel pump will support 300 rwhp at 4000 rpm. That would mean that it will support 450 rwhp at 6000 rpm if the turbos would do it. Could you taylor a boost curve on aftermarket turbo's to limit hp to the fuel pump capability throughout the curve? In other words, 300 rwhp at 4000 rpm, 375 rwhp at 5000 rpm, and 450 rwhp at 6000 rpm (a flat 395 ft-lb)? I know it would sacrifice some low-end capability, but it would still be torquey and fly on top.

Thanks - that's about the best explanation I've heard so far as to what's going on. Since the EB has a very flat hp curve, then the fuel requirement is flat, yet the pump capacity is half at 2500 rpm of what it is at 5000 rpm.
