I was being a little modest with the exhaust ports, they are actually opened up a little, being about the size of the sleeve. I didn't want to make them any bigger than the sleeve and then have the exhuast gases have more turbulence from hitting the edge of the sleeve. Thanks for all your replies! and someday you guys will hear from me about my half bp.... someday... muahahaha.

No its going to be a turbo'ed TII motor... [/quote]

There is a sleeve in the rotor housing for the exhaust ports. Here is some pics of what I mean... I love digital camera's

Another shot. See what I mean? I don't want to open up the exhuast so that the gases hit the edge of that sleeve. I guess I could just port the sleeve some too though...

pulling the sleeve out will increase heat, disrupt flow, and you lose power.

We're talking about bridgeporting the 3rd and 4th intake ports on a 4-port turbo motor (secondaries) and leaving the primaries unbridged.

RICE RACING on the other forum advocates doing this on monster turbo setups. He knows his ****.

yeah you can do that if youre going to be making the exhausts THAT LARGE. but unless youre running some kind of bridge port the gains arent really worth it. ive done it on some engines ive build, i leave them in now

Ummm, the name of the thread is half-bridge, and every post so far has been about bridge porting.....
