Looking for a 1K HP Fuel System..... Well, like most things in life, things don't go as planned, or done in timely manner, since my build will probably never get done, lets go to straight to boost. I already have GT45 turbo, I will use that till it blows, or runs out of breath.
What is needed for fuel pump, and injectors?
I'm not sure if a walbro 450 will get the job done, and not sure about the snake eaters injectors. I want something that is affordable, and I don't want to have that thought of if or when will the injector fail.
This will be a daily for the most part, needs to be reliable.
This will be a 3500lb, car.
Thanks.

What fuel type? Ethanol?
Just some back-of-the-envelope estimation seems to suggest that you need at least 100 lb/min fuel injectors to make ~1200 crank horsepower on ethanol, and you'd nearly be driving those static, so you'd probably want 120s. You'd need nearly 600 lph of fuel pump to comfortably support that much fuel flow, and you may need to oversize a bit past that if you intend to run a 4-bar base fuel pressure.

triple 400-450 pumps is usually recommended for 1000+ on e85. If wanting to try with dual pumps then i'd go with the new 525 "hellcat" pumps f90000285 is the part number. Direct plug and play with the old 450 pumps. 8an feed and 6an return will flow 1000+whp as well
