porting allows more air to enter the chambers. You basically make the ports bigger.
Street-porting is simply making the stock ports bigger. It retains the good idle and driveability, but has the least power of all the porting jobs.
Bridgeporting involves adding a second port next to the original one and leaving a "bridge" of metal in the middle to keep the seals in place. This type of porting has a lot of power(250+ hp), but you get a crappy idle and passing emissions is almost impossible. Driveability also suffers.
Peripheral porting makes the intake ports like the exhaust ports. This is a race-type porting, as you could never get away with it on the street. This type of port gives a lot of power, easily in the 300-400 hp range normally aspirated.
It would be a lot easier to explain if I had pictures. Go to www.pineappleracing.com to see some good pics and explanations.
Do you know how a rotary works? If not this really won't make sense to you.
