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.
Eugene is suggesting I run a DW440 brushless pump. I'm looking at the Radium website that talks about flow vs amp draw and the TI brushless they sell draws very little current for the amount it flows so it's probably going to heat up a lot less. Looks like it's around $600 for one, but of course there are a lot of ways to skin this cat.

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?
