Twin Hellcat pumps is a LOT of fuel. I'm sure that LT5 will need it. Interested to read up more on the fueling on this setup as I'd be willing to modify my fuel system as it's the limitation of my current setup being twin CTS-V.
Looking at the numbers it looks like the hellcat puts out 40% MORE than the V at same pressure and voltage. And on top of that, looking at the flow chart for the pump it's flow doesn't drop off as fast with fuel pressure increase.
**EDIT**
Looking at the numbers, two pumps can support around 1700hp comfortably on E85
