    Anybody know what Brad 5 heads flow out of the box?

    Thanks,

    heads

    call Brad ask for Jeramie,may give you that answer. But I wouldn't worry about flow, it's the velocity for your combo that should be important. Don

    Brad V Flow Numbers

    We have a set on a 451 KB.
    The flow is 480 @.800 intake and 360 @ .750 on the exhaust.

    Hope this helps.:)

    I am interested to know the flow numbers also, but...
    The NA airspeed vs boosted airspeed has to be different, given the same port. And so I have to wonder how much the airflow numbers really correspond to HP output of a boosted engine.

    Let's compare headflow and a car driving on a curve in the road.
    How tight the road curve is represents the shape of the cyl hd port.
    The cars speed represents the airspeed.
    So if the flowbench airspeed represents an approximate airspeed of an NA motors real life running than let's call that 65 MPH in this car. Now onto this road curve (port) in a boosted engine. Because of boost the cars MPH is significantly increased and it would "scrub" a lot less if the curve was straighter.

    I'm not sure I'm making any sense in my explaination.

    Don't get me wrong, we work on airflow on a regular bases, but I would love to see some back to back tests.

    I started experimenting with NA ports and airflow testing vs boosted port shapes last winter and had to stop, so I could get my stuff ready for the track.

    I don't know crap about designing a blown port, so I can only assume that the ports on a Brad 5 are built with that in mind, with little or no consideration for NA. Which may mean that they don't show real hot numbers on a NA flow sheet. I am still curious though. ;)

    I'm curious also. In fact I've asked on here before.
