Which fuel system?

[331 cobra]

I am building a high rpm NA engine and I want to have a good fuel system. It should be able to support 5-600 crankshaft horse power. I'm aiming for about 350 at the wheels, which is about 411 at the fly wheel, but I want to save a little room for a power adder down the road.

How much hp can a walbro 340 (high pressure 255lph), kirban regulator and stock lines handle?

What about inline pumps, should I get the walbro and a T-rex, or will the T-rex just give me more pressure?

What about a T-rex and just a pickup in the tank?

When will the stock fuel lines become the bottle neck?

When will a kirban regulator become the bottle neck?

Which regulators are better than a kirban?

A Kirban is a very good regualtor, either on the rail (stock style) or off the rail.

You can make 450-500RWHP and that is about it on stock lines with being safe, especially in a high rpm motor, some say higher but I'd be worried.

We made 425/467 to the wheels with a blower application, stock lines, stock rails, Kirban, GSS340 (high pressure 255lph) and a ATI inline (basically a T-rex but I like the mounts and wiring better)

Now if you want to put some lines on a -8 feed and -6 return should be fine, if a power adder is going to come into plat use a -10 feed. Any of the good aftermarket pumps and filters, Aeromotive, Weldon, Magnaflow, CPR..... Be prepared for around $1400-$1800 depending on your components.
