    9psi From the Vortech Impeller

    Got 9 psi on my Guage today spinning 8080 Rpms. Went prowling for some prey but a 150F got scared when he saw my big BOOST guage.
    GPS 74.8 with a full tank.

    That impeller can't give you that much of a boost

    Is that a mechanical boost gauge? MEchanical boost gauges are highley innaccurate.

    If the guage is inacurate what sort of boost does the following give you?
    Stock
    Vortech
    Riva Stage 3
    Rude

    Too many variable to pinpoint an exact boost meaurement (type of intercooler, elevation, temp, humidity) but the following will give you a general idea

    Stock 7 psi at 8100
    Vortech 8 psi at 8100
    Riva Stage 3 11 psi at 8500
    Rude 13-14 at 8500

    If the vortech pushes 8 psi @ 8100 would it push 9.2 @ 8280 rpm with a RR IC?
    Thats what I was seeing with my S2 setup.
