Bridgeport question
 
I am under the impression that I am not supposed to use the rubber plugs in the corner seals on the bridge side, correct?
Am I also correct that the apex seals must be flipped so the triangles do not ride on the bridge side?

No.
Unless you are referring to partial bridge engines (where only the secondary ports are bridged), then I can see why you would ask that due to the 2nd rotor having the triangle piece facing the bridged side
Off the top of my head, I can't remember about the rubber inserts on the corner seals, but I am under the impression that they will fall in in short time. However, take take my word for that, as I've only street-ported all the engines I build. You can opt for solid corner seals from Atkins though...

whoops, yeah i should have been clear on what engine i am doing. 13brew with the Bridgeport on the secondary side.

Just so im not misunderstanding you, I would need to flip the seal on the one rotor? I'll check out the solid corners seals, any drawback to using them?

Use the solid corner seals, they are better and yes the rubber plugs will eventually fall into the engine and may cause damage if used in a bridgeport motor. Plus all they do is aid on start ups.

If running a half bridge then yes you would have to flip the seals so the corner piece is facing the primary ports and not the bridge ports.

Does it matter that much ? I seen few full bridge running 2 piece seals.
What advantage does 1 piece seals hasve on a full bridge?

Depends on how big the bridge is. I heard of the small triangel piece of the seal falling into the port.

You always face the smaller piece away from the secondary ports on a half bridge. If you understand the reasoning to this then you can understand the benefits of a one piece apex seal on a full bridge setup.

Flip the seals around so the small piece faces the intermedia plate,im running a HBP with the rubber plugs only removed on the bridgeported plates(i keep the ones facing the center plate)and is start right up and i dont have comp. issues.120PSI
