Fuel supply I'd like someone to recommend a fuel pump for up to 600 hp. Will I need a pressure regulator in the system or not?
Any one know the fuel delivey capacity of the stock fuel rails? Should I uprate them? Suggestions?

Re: Fuel supply a dual intank walbro 340 would do nicly
you could use a single walbro and increase the voltage, but a dual would be better imo.
id get a arftermarket regulator too. like a charged air boost and vacuum reference.

Re: Fuel supply I've seen it in person! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> Looks killer too, not to mention flows a shitload of fuel.

Re: Fuel supply Holy Moly!!
Good job and a great set of pictures MM.
How do I work out the required pump pressure for my set up? (42lb injectors running a clean 500rwhp through twin turbos.)
Does the pump just keep pumping and the regulator restricts flow, or does the regulator just smooth things out?
Oh, and are the stock fuel rails up to the job.
Cheers guys.

Re: Fuel supply I dont think the stock lines or the rails or even your 42# injectors are what it will take to comfortably run 600rwhp, after all, that is what i upgraded from.
the pressure you need just depends mostly on what you want to run, since you can adjust the same sort of thing with injector flowrate in the comptuer.. mine is at 60psi at 0 vaccum.
the regulator sets the fuel pressure, without it you would only have fuel pressure based on the friction in the lines, pretty much nothing which is unacceptable.
