First of all I say leave it here, I think people need to see this . If it were me when you start going that fast it is a matter of volume as well as pres. I would use a sumped tank or cell with -10 into a big 1000 hp pump, one stable over 65psi , some over heat at 65 real bad, or can't flow the amount adv over that. Then -10 into a y-block at the rails, equal -8's into the rails and out into a 4 port reg then -8 back to the tank. Some may think a system like this is overkill but what's wrong with that. If you are going to run those king os trap speeds you need 700+ HP , that takes fuel and a bunch of it . Lot's of people have run those speeds with a lot less. My thinking is that why run on the edge or even near it. I like lots room to work with when it comes to fuel. To much can always be backed down, not enough can't be streched.
