redondoaveb ran out of duty cycle but keep in mind he was running on e85 so takes more volume/fuel to get the same numbers that's why he needed bigger injectors and pumps. I hit 650 with rails and the hellcat pump running 1300cc injectors at under 80% cycle. Keep in mind you are be going to want to move volume over pressure. I feel like you shouldn't want the pumps fighting each other. But again depends on your setup as a whole unit |

I bet a 450 with a KB-BAP would flow enough for 800+whp and cost $400. I think those brushless pumps are well over $1k. We made 710whp on that setup with stock rails and fuel pressure didnt drop one bit.

Also I just noticed that injector dynamics has a fuel flow calculator on their website too. Even with 20lbs of boost and E85 they're only calculating 355lph at redline. Does that seem low to people? Last edited by HapaZ; 10-28-2021 at 03:36 PM. |
