    Ported 6.4 intake resaults

    Just wondering how people made out with the ported 6.4 intake. I was thinking about having it done for one of my cars, just wanted some input.

    There's a thread where this was discussed some time ago, but can't remember which. The consensus was no gains as the stock intake is pretty much the as good as it gets on a stock or bolt on care. If going FI I believe the 6.1L intake is the preferred choice since it gets rid of the adjustable intake runners(?, think that's what they are called). The 6.4 can cause one bank to lean out due to these.

    It's not the runners that make it hard to tune, it's the entry angle of the air due to the neck of the 6.4 intake. That's what causes one side to be rich and leans the other side out.

    On a bolt on, N/A car it's hard to beat.

    Porting is a waste of time and money on NYLON6 intake manifolds.

    Garden variety boost levels are fine, serious boost levels are not as the air flow into the plenum is significant enough to lean out most of the right bank. I wouldn't bother with porting NYLON6 manifolds on engines which are pressurized, as any gains as seen on NA engines are definitely moot.

    Thanks, I've seen some of the other threads, just wondering long term.
