I have just downloaded Autodesk Simulation CFD, so when i learn how to use it i might try to get a flow simulation betwean a real bp and this drilled/swiss cheese version.

Did I point out that the only difference (drivability, economy, powerband) between a small bridge and a large one is the amount of power you make?
I did?
I'll make the point again. There is no point to making a "small" bridge. Once you open up past the cornerseal, you will have all of the same drivability/tuning sensitivity problems no matter if it is a 1/4" hole or a full height water seal eating eyebrow. The only difference is that the bigger port will actually be worth the hassle. I've tried all sorts of combinations and I've "settled" on eyebrows as big as possible without hitting water jacket on the secondary side. Only because I run 2 piece apex seals and I don't want to relieve the rotor housing where the short piece is.
I predict no more power than an equivalent street port, probably less.

yeah you already did peejay, how about you wait till my build is finished and then after my dyno results, and if i don't make over 200whp, than i'll gladly accept that it those port don't work, but for now all i hear is bashing,
i've also saved my Lightened Rotors for a different build, i'm using my S5 NA rotors for this engine

So do it then! I had my first half bridge engine ported and back in the car in less than two days. Do it to it!
BTW - I'm not close to 200whp unless you configure the dyno to inflation mode.

Got it up and Running about 2 Weeks ago,
here are some Details of my setup
s5 NA Domino bridge port , S5 NA lower manifold with minor porting i did
Racing beat upper manifold modded with Fuel injected bungs and bracket for fuel rail and also ported
Custom made my own adapter/spacer to fit a Mustang Cobra dual 54mm Throttle body
S5 Motor , Goopy 2mm 2 piece Seals , all new seals and Bearings 8Lb flywheel, RB Eshaft Pulley, custom gauges made by speed hut
Microtech Lt10 with X4 box with 4 fc trailing coils, Headers are RB and exhaust is a Vibrant Single but i plan to change that with a better exhaust awr as soon as i get it
i still have some other stuff to install like my wideband, fuel cell, and cage strut bar, a fan shroud i'm currently making but for, and clean up wiring , Here are some pics
