Never understood why people spend such huge dollars on those things specifically, and huge overkill on fuel systems in general.
I got talked into( via peer pressure) taking a perfect working dead headed Holley black off a hard leaving legit 650 horse 9 sec street strip car, and put an expensive return style system/ much bigger pump on the car.
It didn't run a thousandth of a second better than it ran for years with the black. I am sure the black would have supported even more power, as long as it gets good steady voltage
My 2-cents,
For a 600 hp car running gasoline, it doesn't take much of a fuel pump. Maybe 50 GPH plus some reserve (say a 90 GPH rating).
Now a 1000+ hp engine running alcohol needs to move some fuel!
