I'm hoping somebody can go over some port types for me...
I searched and read bits and pieces. I'm looking to port my engine in the near future but I dont know much at all about the different types of ports. So far I've heard street port, large street port, 1/2 bridge port, bridge port and extended port. I read that bridgeport can make up to 250hp if tuned properly and ran on a standalone.
1) What kind of horsepower would a 1/2 bridge port put down and would u still need the standalone?
2) I know that bridgeports effect the engines longevity but how many miles can you put on to a bridgeport before you need to start worrying?
3) Would a half bridgeport last longer?
4) How much horsepower can you gain from a large street port?
thanks a lot guys
really confused about all this just need some clerification.

Does anybody have any basic knowledge on porting? I'm trying to decide what I want to do so I know what I want and how much I need to get it done but I want to understand it a bit better. I've been searching and researching and im just down to the 4 questions listed above.
Any help is apreciated thanks

i got a s5 tII. No specific desired horsepower... I just like what I'm at, then want more late. Right now its at 240 at the wheels and im wanting a bit more... injectors, fuel pump, exhaust, intake, t3/t4 turbo, s-afc, ported waste gate, blow off valve, FCD is pretty much all thats done. Thanks. ONe thing I'm curious about is why people get mild street ports instead of large ones? Are there downsides to larger street ports that I'm not aware of?

The main thing I know of as a downside to the larger street ports is that you can get a bit of a lumpy idle with a larger street port, but nothing too bad (unless your TPS is out of calibration like me). Other than that I dont know of any reasons not to get a larger street port.

A bridgeport NA can make up to 250 HP if tuned with a standalone. A bridgeport T2 with a standalone, would make CONSIDERABLY more power than that, heh. Notice, with a full exhaust on you're T2, you had to have made quite a bit of horsepower, if it was quality, anyways. With all the mods you listed, you should have a bit more then 240 HP ?
With those mods, you should have considerably more then 240, No doubt in my mind. S5 T2, Something like (170?) HP to the wheels stock, exhaust/intake, exhaust done right would be an easy 30HP, Intake, depending on how you did it, is +/- 3-5 HP, Fuel pump+injectors/S-AFC/FCD, would set you at like, give or take a few, 230-240 HP at the wheels. But then a T3/T4...You'd be looking a little over 240 I think. Anyways, off topic, Street Ports last a lot longer then bridgeports, as the "bridge" or, the part the side seal rides across, tends to crack after use. Not sure exactly how long it can last, but I think you can make the bridge thicker (not massively, 1/30 inch thick like I've seen on a bunch of car's..) so it won't crack under such little use. Stand alone is a must for bridge, as you're idle will need to be set higher, more fuel, etc. Large Streetport, drawbacks include slightly less engine life as far as I know, and bad emissions.
injectors, fuel pump, exhaust, intake, t3/t4 turbo, s-afc, ported waste gate, blow off valve, FCD is pretty much all thats done.
