Bridgeported engine results

BDC did my bridge port, A local did my assembly, and I have close to 50k miles on the motor. So I don't think that reliability is an issue when it's assembled properly. The problem is the limited gain vs reliability.
Power wise, it's not worth the cost unless you're just looking to squeeze that extra 5~10HP out of the motor (if that). As WTBRotary! said... Engine dyno plz. You'd have to have the same person spec out very similar engines, then compare the 2 with one ported and the other stock. I doubt that the numbers would be very drastically different to even justify the cost of establishing those perfect world numbers.
One thing I can say for sure is that an N/A bridge port is not going to add 20HP even in a perfect storm. I stand behind my earlier comments that there are much better ways to spend your money to make an RX8 fast. For the cost of shipping and and or labor, I don't even think that it's worth doing "just because it's already torn down". The N/A gains just aren't there with porting when compared to earlier 13bs, and when you start throwing FI in there, you REALLY can't quantify the impact of the porting.

rev it up
I believe Ric Shaw experimented with bridgeporting in the early years to look for gains so he could offer the service to his customers. He did not find any major benefits so after a few attempts so he does not recommend this to his clients.
He is offering a "custom port" as part of a rebuild with proven gains.
