    30lb injectors and 12-13psi

    My uncle just bought him a T-trim. He is planning on putting on his 351 EFI with a GT-40 intake, GT-40 heads, and a F-cam. Pulley combo will be 3.15 blower, and 7inch crank. He was told by Vortech that 30lb injectors will be fine with a FMU, he will be using my SFMU. I think he is crazy. 30lb injectors isn't enough IMO. Do yall think it will hold up? Heck I'm using 30lbs now and about to swich to 50's.
    89 GT - old combo -AOD, S-trimed, 302, stock short block - 6.67@106 with a 1.60 60ft, 4.10 gears. dyno 474rwhp, best in 1/4 3.55 gears 10.83@128 1.67
    Damn them stock cranks :(
    new comb in the works Dart 331 turbo :D

    98 GT - its a turd, but I like it ;)

    with an fmu it it'll live but he'll never get the most out of it with an fmu.
    89 Coupe with parts stacked inside of it and about 30#'s of dust on it with no end in sight. :weird:





    Although I am collecting parts for a 12.5:1 393 :D

    agreed, fmu is no more then a "band-aid" approach..... Talk him into bigger injectors and a chip/tuner.
