    Whats your fuel system setup? Line size, rail size, injector setup, psi, regulator location, pump(s), etc? Im reading some conflicting info and am curious to what you guys say. 800+ hp/40+psi, with a little nitrous sprinkled on top.

    Thanks!

    It's strange you should ask this on a 800+hp build but FPR is after the injectors on or past the return end of the fuel rail. You want the regulated pressure available to all your injectors & low pressure for the return line.

    This is only my opinion but most of the site members doing a 800+hp build know the basics, inside & out.

    Yup, makes a ton of sense. Im coming from the V8 world, where ive had high hp blow thru turbo and nitrous combos. 1000hp Ponchos and Fords, i can recite in my sleep. I also had an 11 sec Evo waaaaay back in the days. This time want to put a 1g 4g63 in a rwd domestic. Also my first time with FI on a high level, so im gathering as much info as possible. Thanks for the help. Its really appreciated.

    I of course run the mechanical, it has its ups and downs, the expense being a down, the mounting and lines being a down, the up is that its the last pump you will need. You can look in my pictures for views.

    Homemade pump mount running off of the exhaust cam, Aeromotive mechanical pump, Aeromotive big regulator for mechanical pump, dual Magnus fuel rails, (8) 1000cc staged injectors, -8 an feed, dual -6 an returns.

    Thats likely because there tends to be a human flaw, such that we think that whatever we have is the best, otherwise we wouldnt have chosen it, aka: we dont like to admit being wrong...
