I've got an extra engine with a medium pineapple street port on my 13brew. I cracked it open with thoughts of adding a brow to make it a bridgeport. I've traced the corner and side seal paths and it looks as though most of the meat for the bridge has been taken by the street port itself. If I added a bridge it would only be about 3/16" wide in order to keep enough meat on the seal path. Has anyone done this or am I wasting my time.
This is my "Fun" engine that I'm dickin' around with and kinda want the *brap* sound. I also plan to open up the exhaust ports to a RB race port (currently stock), would this make my *brap* or is it all in the bridge?

 

3/16 is not enough,you need enough material to support t least 50% of the corner seal and remember the side seals needs to be 100% suported(rinding on the bridge all the time)if not it will eat a side seal.

 

What I meant to say was the eyebrow is only going to be 3/16th in width, not the bridge.

 

Yes you can add one depending upon the width of the bridgeport cut as well as the width of the existing port job on the standard intake port. The goal is to leave as much of a bridge leftover as possible. You don't need a humongous bridgeport cut to induce alot of overlap to then produce the desired effects.

That's what I was hoping for, thanks.

 

Your original statement was good, he just did not read it correctly.
