    Yep, this is one of the few cases where tighter is not always better.

    canister purge line is closed by the canister purge solenoid until the ecm tells the solenoid to open. This is usually at cruise

    So would this be a bad source for running a boost line? Would the FMU line would be a more optimal place since it's always in closed loop just like the EGR and Fuel Pressure Regulator?

    when cruiseing I see the vac at 16 and when I just put my foot in it more it go's to 0.

    and going to 3,500rpm I thought it was 2,500rpm

    Not sure, but either way it's the same amount your FMU is seeing so it's gotta reflect somewhat what the motor is seeing.

    I got mine from uprproducts.com for $99 when they first came out. I see they went to $130 but have heard if you shop around 5.0 Magazine and MM&FF you can find it for $99 still.

    This is what I went through.

    -Stock motor/SC-Trim setup = 4psi

    -Stock motor/SC-Trim with 2.89" supercharger pulley = 5psi

    -Ported Heads, Intake, 80mm Pro-M meter, UPR powerpipe with SAME pulley = 10psi.


    This leads me to believe the power pipe and 80mm mass air meter made a HUGE difference in cfm flow from the supercharger. I recommend it!! (I would get bigger injectors and a bypass valve though so it's not as easy as bolting it on) Well it is but the increase in horsepower might overpower your fuel system..

    ahh I hope I confused you on that last part.. :p

    :lol:

    I since have taken your advise and installed the a/c line under the discharge tube (Was easier to do than I thought :bang: ). I would take a new pic but (once again) my motor is torn down to the shortblock awaiting a 331 from Rick :banana:

    Depends on your plans with the motor. If you plan on doing heads and an intake in the future, you should go with 42#'ers right now and a 80mm Pro-M meter. If not, I'm sure you can get 24's or 30's. It's just a pain to recalibrate your meter if you ever want to upgrade to larger injectors so I like to do it once and leave a little room to grow.

    All you need is a new Mass Air Meter and Injectors. Also if you haven't already, get yourself a 255lph "High Pressure" In-tank fuel pump. It's also called a GSS340.

    So your new motor is getting boosted with the Sc-Trim?
