Alright well I searched for it, but my question is...What is the difference betweena bridge port and a street port....I know on a street port they port out the openings to the intake and exhuast ports....so what exactly is a bridge port? sorry I'm still really new had my car less than 6 months probably

 

A bridge port has another lip above the street port.

thanks alot...I don't suppose I could pass emisions with that?

 

when talking about a bridge port, dont ever plan on mentioning, or thinking about emissions, EVER!

 

haha well in Phoenix I gotta think about that kinda stuff...

 

it would never pass emisions or be trully "streetable" for that matter, 2000rpm idle, very loud, and horrid gas milage.

in other words i want one bad, when this engine goes bridge port is on the way.

 

haha It sounds badass...don't think I could afford something that dramatic though...

 

LOLZ yea, dont plan on safley passing any emission tests.

 

that is why its good to have an area that doesnt do emission

 

I have honestly thought about a mild half bridge. That would make some decent power over a street port I would think.

 

Mine seems to idle well at 1500 RPM, and isn't too loud. Of course it will idle a bit lower once the engine is broken in and it has been tuned.

Honestly in these days of programmable standalones, bridges are not nearly as nasty as they once were.

Gas mileage also isn't too bad, especially on the highway.

 

just get a mild street port if you have to worry about emmissions... BUT, if you have the hook-up over there for smog, then go right ahead with the b-port....

 

AFIK, the more extreme the porting gets, the lower the life expectancy of the motor, am I right?

So that's definetely something to keep in mind when selecting a port for your engine.

 

There's really no such thing as a "mild" bridge. A half bridge (only the secondaries get an eyebrow) is the only form of a "mild" bridge.

And yes, a bridge will make more power then a streetport - is Captin Obvious standign behind you or something??

 

How loud it is depends a lot on the muffler. Sure you have have a super loud bridgeport by using a large single can like the N1, or you could use the RB duals and have a reasonable sound level.

 

Depends. In theory a bridgeport should be no more or less reliable then any other port if the bridge does not intrude into the side seal track or corner seal area in a bad way, or if it is not too thin.

The real difference in porting is that a ported engine is much more likley to be run hard, thus the lower reliability...

 

I dropped the half-bridge idea and went full instead, I'll never look back. Bridge if you are wanting serious power, take advantage and run a large turbo. Oh yeah getting all your emissions done is tricky unless you have good friends.

 

LOL - you need to tell this to Jim K...

I tried explaining that to him but he gave me **** because I was 1/2 bridging a motor that was going to be turbo'd hehe...

But it should be reliable enough for my needs.....

 

New person pipe dreams.

Honestly. A bridge is for someone which has already hit 300+hp and knows rotaries and EMS's well.

You can easily get the hp you want without porting if your turbo. Jrat's proven that.

NA's.... well the only NA I think is worth while is a 20b.
