Quick video showing a half-bridgeport plus street port I performed on a Series 5 front iron housing. Video taken in summer '04.

  • It's done by hand. Thank you.

  • hi mate clean job . what hp are you looking for out of them . and being so smooth is;nt that a draw back as the air fuel wont attermise properly ?

  • It's not terribly smooth but that is a valid point. I don't finish the intake ports quite as smooth as I used to when I took that video for the very reasons you've brought up.

  • What do you use to get it so smooth? I've tried out a little bit of porting on an iron I had lying around, and it didn't come out nearly that nice, lol.

  • Im Thinkin Kay rolls and fine grit cross buffs would do it, Though this one looks like its CNC ported.

  • Flapwheels but basically you're right. Thanks for the compliment on the CNC porting; it's actually all hand-cut and done by eye without a template. I do have a methodology behind how and where I cut the bridgeports to help ensure that they're equal dimensions on both outer plates but they're all done by hand.

  • Lots and lots and lots of sanding steps. It's tedious.

  • Nice porting but I always wanted to know is how this gives the pulse sound the brideport makes...

  • hell yeah,brooklin bridge

  • Have you nitrated those plates ?

  • @bdc196 Its just that good......LOL

  • very good job

  • Would that be considered a MONSTER port?

    It's freakin huge and the bridge looks rather thin for a long lasting street car. Full race engine i assume?

  • Do mine next?

  • thats some nice porting!

    if i was to give you my s4 13b n/a plates,how much would you charge to do a full bridgeport job?

  • thats HUGE. but will it really work? looks a bit big
