    don't ls1's run at 4 bar and if it's a 3 bar injector you would have to convert it to a 4bar inj. i think i heard this from horist

    Static Flow Rate: 57.7 lb/hr @ 58.0PSI (400kPa) 606cc/min or 7.4gm/sec
    Dynamic Flow Rate: 1.1 gm/pulse - 2.5ms pulse width and 10ms repetition rate @ 43.5PSI (300KPa)

    what is it going in...whats the rated fuel rail pressure...
    important to know...

    and my #'s are for a 4 bar car...meaning LS1 fuel rails at 58psi
