Talking Difference between ports

What's the difference between 1/2 bridge than a full bridge?? Is the 1/2 bridge legal and full illegal? I love the sound of a bridgeported motor and I myself would like to get one, soon as the motor blows!

What do you mean by legal? For emissions, neither are going to pass.

A half bridge is only bridged on the secondary runners while a full bridge is on both runners.

Next time, Search. Its your friend.

Yes and no. To be more specific, a half-bridge refers to the extra port on the front and rear iron. On a full bridge, you are adding the extra port hole on all four iron faces, both secondary and primary (intermediate housing.). The half bridge is more streetable than the full bridge.

Nope. A half-bridge is one more step towards "race car." With a half-bridge you are going to have a higher, lumpier idle, and you will derive greater benefits from a larger turbo/higher boost. It can be streetable, though. I'm sure 93blackfd will chime in at some point
